Variaciones anatómicas de las arterias radial y ulnar en miembros superiores plastinados / Anatomical variations of radial and ulnar arteries in plastinated upper limbs

Los avances en el área de la salud, con el desarrollo de nuevos procedimientos diagnósticos y quirúrgicos, requieren un conocimiento cada vez más preciso de la anatomía humana. La difusión de la disposición variable de la anatomía resulta primordial no sólo en el campo de la especialización o el postgrado, sino por sobre todo, en el pregrado, desde donde se formarán los especialistas que luego desarrollarán esas nuevas prácticas clínicas y quirúrgicas que requerirán una sólida formación anatómica. Es por esto que la aplicación correcta de técnicas anatómicas en las muestras anatómicas es fundamental para que esta enseñanza en el pregrado pueda desarrollarse de manera eficiente, teniendo la plastinación un rol fundamental en este sentido. El objetivo de este trabajo consistió en dar a conocer el hallazgo de variaciones anatómicas arteriales en los miembros superiores de una muestra humana sometida al proceso de plastinación para fomentar, por un lado, la importancia del conocimiento anatómico en el pregrado, el postgrado y las especialidades, como así también la relevancia de la preservación a largo plazo de material biológico para la difusión continua de la anatomía.

SUMMARY: Advances in the area of health with the development of new diagnostic and surgical procedures require an increasingly precise knowledge of human anatomy. The diffusion of the variable arrangement of anatomy is essential not only in the field of specialization or postgraduate, but above all, in the undergraduate, from where the specialists will be trained who will later develop these new clinical and surgical practices that will require a solid anatomical background. This is why the correct application of anatomical techniques in anatomical samples is essential for this undergraduate teaching to be developed efficiently, plastination having a fundamental role in this regard. The aim of this work was to report the discovery of anatomical variations in the upper limbs of a human sample subjected to the plastination process to promote, on one hand, the importance of anatomical knowledge in undergraduate, postgraduate and specialties, as well as the relevance of long- term preservation of biological material for the continued dissemination of anatomy.

Síndrome compartimental após ruptura espontânea de pseudoaneurisma da artéria radial esquerda / Compartment syndrome after spontaneous rupture of a left radial artery pseudoaneurysm

A abordagem transradial é indicada para reduzir risco de morte, complicações vasculares ou sangramento. Em pacientes com doença cardíaca isquêmica estável, a abordagem radial é recomendada para diminuir sangramento no local de acesso e complicações vasculares. As complicações são raras, podendo ocorrer hematoma, perfuração e, muito raramente, pseudoaneurisma da artéria radial. Neste relato de caso, é descrito um caso raro de pseudoaneurisma da artéria radial esquerda associada à síndrome compartimental no antebraço esquerdo após realização de cateterismo eletivo. O diagnóstico foi confirmado por ultrassonografia com Doppler, que evidenciou pseudoaneurisma da artéria radial esquerda, medindo 2,1x1,5cm, com colo de 0,3cm. O tratamento cirúrgico do pseudoaneurisma e da síndrome compartimental restaurou a função completa do membro.

The transradial approach is indicated to reduce the risk of death, vascular complications, or bleeding. In patients with stable ischemic heart disease, the radial approach is recommended to reduce vascular complications and bleeding on access site. The complications are rare, and hematoma, perforation, and pseudoaneurysm (very rarely) of the radial artery may occur. This case report describes a rare case of left radial artery pseudoaneurysm associated with compartment syndrome in the left forearm after elective catheterization. The diagnosis was confirmed by Doppler ultrasonography, which showed a left radial artery pseudoaneurysm, measuring 2.1x1.5cm, with a 0.3-cm long/wide neck. Surgical treatment of pseudoaneurysm and compartment syndrome restored full limb function.

Introdução: Dispositivos externos compressivos após a punção radial para cateterismo cardíaco e intervenção coronária percutânea visam à hemostasia, ao conforto para o paciente e à segurança. O estudo objetivou avaliar pacientes submetidos a procedimentos coronários invasivos por via radial, nos quais se utilizou um curativo compressivo e de baixo custo, desenvolvido no serviço, avaliando a segurança dele e a ocorrência de complicações. Métodos: Indivíduos submetidos à coronariografia e à intervenção coronária percutânea, avaliados no momento de retirada do curativo compressivo e após 7 dias, por meio de questionário abrangendo comorbidades, quadro clínico, tempo do procedimento e de compressão, avaliação física de hematoma e dor, e Doppler vascular sonoro para avaliação de oclusão da artéria radial. Resultados: Foram avaliados 144 pacientes, sendo 138 com seguimento em 7 dias. Os eventos não diferiram entre procedimentos diagnósticos e terapêuticos. Na avaliação imediata à retirada do curativo, revelou-se incidência de 4,2% de oclusão da artéria radial, com dor referida em 23,6% dos pacientes, graduada em 2,9±1,7 pela Escala Visual Analógica (intensidade de zero a dez) e sem sangramentos graves. Hematoma ocorreu em um paciente (0,9%), com classificação III pelo critério EASY. Na avaliação de 7 dias, a incidência de oclusão da artéria radial foi de 2,2%, a dor foi referida em 11,1% da amostra (intensidade 1,8±0,8), e o hematoma foi evidenciado em 3,5%. Conclusão: O curativo compressivo mostrou-se um procedimento seguro, com baixa taxa de complicações e baixa taxa de dor local nos pacientes submetidos a procedimentos coronários invasivos pela via radial.

Background: External compressive devices after radial puncture for cardiac catheterization and percutaneous coronary intervention aim at hemostasis, patient comfort, and safety. The objective of the study was to evaluate patients undergoing invasive coronary procedures by radial approach, in which a low-cost compressive dressing developed at the service was used, assessing its safety and the occurrence of complications. Methods: Patients undergoing coronary angiography and percutaneous coronary intervention, evaluated at the time of removal of compressive dressing and after 7 days, by means of a questionnaire addressing comorbidities, clinical picture, procedure and compression time, physical assessment of hematoma and pain, and a vascular Doppler ultrasound to evaluate radial artery occlusion. Results: A total of 144 patients were evaluated, 138 of whom were followed up within 7 days. Events did not differ among diagnostic and therapeutic procedures. In the immediate evaluation after removal of dressing, an incidence of 4.2% of radial artery occlusion was observed, with pain reported by 23.6% of patients, graded at 2.9±1.7 points in the Visual Analogue Scale (intensity of zero to ten), and no major bleeding. Hematoma occurred in one patient (0.9%), classified as type III according to the EASY criteria. In the 7-day evaluation, the incidence of radial artery occlusion was 2.2%, pain was reported in 11.1% of sample (intensity 1.8±0.8), and hematoma was evident in 3.5%. Conclusion: The compressive dressing proved to be a safe procedure, with a low rate of complications and a low rate of local pain in patients undergoing invasive coronary procedures via radial approach.

Efeito da nitroglicerina no espasmo e na oclusão da artéria radial em cateterismos transradiais realizados em mulheres / Effect of nitroglycerin on radial artery spasm and occlusion in transradial catheterizations performed in women

Introdução: O benefício do cateterismo transradial já foi confirmado em pacientes do sexo feminino. Mulheres submetidas a exames por cateterismo transradial apresentam desafios únicos. A ocorrência de espasmo e oclusão da artéria radial após o procedimento é maior em mulheres. Objetivamos avaliar o benefício da nitroglicerina na redução de espasmo e oclusão da artéria radial em mulheres submetidas a cateterismo transradial. Métodos: Estudo multicêntrico, prospectivo, randomizado 2x2 fatorial, duplo-cego. Participantes foram randomizados para nitroglicerina 500mcg ou placebo em dois momentos: após colocação do introdutor hemostático e antes da retirada. A avaliação de espasmo da artéria radial foi clínica, por meio de escala dor. A avaliação da oclusão da artéria radial foi realizada com Doppler, nas primeiras 12 horas. Resultados: Foram incluídos 2.040 pacientes, sendo 774 (37,5%) mulheres. A média de idade foi similar entre os sexos (62,2 anos versus 61,5 anos; p=0,27). A incidência de espasmo da artéria radial foi maior nas mulheres (21,2% versus 6,6%; p<0,01), bem como a incidência de oclusão da artéria radial (3,4% versus 1,8%; p=0,03). O uso da nitroglicerina no início do procedimento não reduziu a incidência de espasmo da artéria radial em mulheres quando comparado com o placebo (19,7% versus 22,6%; p=0,34), tampouco as taxas de oclusão da artéria radial (4,3% versus 2,5%; p=0,17). O uso da nitroglicerina ao fim do procedimento não reduziu a incidência de oclusão da artéria em mulheres (2,8% versus 3,9%; p=0,37). Conclusões: O espasmo e a oclusão da artéria radial são mais frequentes em mulheres submetidas a cateterismo transradial quando comparadas aos homens. O uso da nitroglicerina não apresenta efeito benéfico na redução dessas incidências.

Background: The benefit of transradial catheterization is well established in female patients. Women undergoing transradial catheterization exams present with unique challenges. The occurrence of radial artery spasm and occlusion after the procedure is higher in women. The objective of this study was to evaluate the benefit of nitroglycerin in reducing radial artery spasm and occlusion in women undergoing transradial catheterization. Methods: This was a 2x2 factorial randomized, multicenter, prospective, double-blinded study. Participants were randomized to nitroglycerin 500mcg or placebo at two time points: after placement of the hemostatic introducer and before its removal. The evaluation of the radial artery spasm was clinical, using a pain scale The evaluation of the radial artery occlusion was performed with Doppler, in the first 12 hours. Results: A total of 2,040 patients were included, of which 774 (37.5%) were female. Mean age was similar between sexes (62.2 years versus 61.5 years; p=0.27). The incidence of radial artery spasm was higher in women (21.2% versus 6.6%; p<0.01), as well as the incidence of radial artery occlusion (3.4% versus 1.8%; p=0.03). The use of nitroglycerin at the beginning of the procedure did not reduce the incidence of radial artery spasm in women when compared with placebo (19.7% versus 22.6%; p=0.34), nor did the rates of radial artery occlusion (4.3% versus 2.5%; p=0.17). The use of nitroglycerin at the end of the procedure did not reduce the incidence of artery occlusion in women (2.8% versus 3.9%; p=0.37). Conclusions: Radial artery spasm and occlusion are more frequent in women undergoing transradial catheterization when compared to men. The use of nitroglycerin does not have a beneficial effect in reducing these incidences.

Comparison between free wrist crease flap pedicled with superficial palmar branch of radial artery and traditional free toe flap in reconstruction of hand soft tissue defects: A study on clinical efficacy / 中华显微外科杂志

Objective:To compare the difference in clinical efficacy between a free wrist crease flap pedicled with superficial palmar branch of the radial artery flap (SPBRAF) and a traditional free toe flap (TFTF) in reconstruction of hand soft tissue defects, and to provide reference for the treatment of small-to medium-sized hand soft tissue defects.Methods:Data of 37 patients who received hand surgery in Department of Hand Surgery, No.971 Hospital of the PLA Navy from December 2016 to December 2019 for small-to medium-sized hand soft tissue defects were retrospectively studied. Among the 37 patients, there were 32 males and 5 females, aged between 18 and 65 years old, with 41.5 years old in average. According to the reconstructive surgical procedure, patients were divided into SPBRAF group (22 cases) and TFTF group (15 cases). Regular follow-ups were conducted after surgery. The difference in curative effect at the last follow-up between the 2 groups was evaluated by the comparison of data acquired in follow-up. SPSS 25.0 was used to analyse the data statistically. The evaluation indicators included flap survival, long-term recovery of flap, recovery effect at donor site, total active movement(TAM) of the affected digit, time of hospital stay and the time return to work. P<0.05 was considered a statistically significant. Results:All free flaps survived. All patients were entered 6-18 (mean, 10) months of postoperative follow-up to comprehensively evaluate the therapeutic effect. According to the Evaluation Trial Standards of Upper Limb Partial Function of Hand Surgery of Chinese Medical Association, in the SPBRAF group, 20 flaps were found in excellent, and 2 in good; in the TFTF group, 14 flaps were found in excellent, 1 in good. There was no statistical difference between the 2 groups( P>0.05). The colour, texture and thickness of flaps between the 2 groups were either in excellent or good. There was no statistical difference between the 2 groups( P>0.05). TPD in the TFTF group (5-6 mm) was better than that in SPBRAF group (6-7 mm) with statistical difference between the 2 groups ( P<0.05). Texture at donor sites between the 2 groups was either in excellent or good ( P>0.05). In terms of appearance, sensation and recovery time of donor site, it was found that the SPBRAF group(mean, 6 weeks) was significantly better than those in the TFTF group(mean, 8 weeks) and there was statistical difference between the 2 groups ( P<0.05). In terms of recovery of TAM in single-digit, excellent or good were shown in both groups and there was no statistical difference between the 2 groups ( P>0.05). In terms of hospitalisation and time for return to work, the SPBRAF group(mean, 8 days and 17 weeks) was significantly better than that of TFTF group(mean, 12 days and 24 weeks), and there was statistical difference between the 2 groups ( P<0.05). Conclusion:SPBRAF has an ideal effect on reconstruction of small-to medium-sized hand soft tissue defects in hand. Although the flap is still inferior in sensation and appearance compared with the TFTF, the advantages in terms of donor site recovery, patient satisfaction of the donor site and reduced time of hospitalisation and return to original work are more obvious. SPBRAF provides a good complement to surgical procedures reconstructing a digit defect.

Application of hemostatic bandage in wound management after transradial coronary angiography and/or interventional therapy / 中国实用护理杂志

Objective:To explore the clinical effectiveness of hemostatic bandage on wound safety and comfort after transradial coronary angiography and/or interventional therapy.Methods:This was a experimental study. A total of 400 consecutive patients who underwent transradial coronary angiography and/or interventional therapy in the Department of Cardiology, Peking University Third Hospital from July to October 2022 were enrolled and randomly divided into the hemostatic bandage group and the hemostatic balloon compressor group by the envelope method with 200 cases in each group. The hemostatic bandage group and the hemostatic balloon compressor group were treated with hemostatic bandage and hemostatic balloon compressor as transradial artery hemostatic device, respectively, to observe and compare postoperative hemostatic effect, hemostat use time, complication rate, postoperative pain, the degree of numbness in the finger on the operated side and wristband comfort between the two groups.Results:The hemostatic success rate was 98.5% (197/200) and 99.0% (198/200) in the hemostatic bandage and the hemostatic balloon compressor group, respectively, with no statistical difference ( χ2=0.20, P>0.05). The hemostat use time in the hemostatic bandage group and the hemostatic balloon compressor group was (6.23 ± 0.47) h and (17.01 ± 7.74) h, respectively, and the difference was statistically significant ( t=-19.66, P<0.01). The incidence of complications in the hemostatic bandage group and the hemostatic balloon compressor group was 13.5%(27/200) and 29.5%(59/200), respectively, and the difference was statistically significant ( χ2=8.01, P<0.05). Among the complications, swelling occurred in 21 individuals of the hemostatic bandage group and 54 individuals of the hemostatic balloon compressor group with statistically significant differences ( U=16 689.50, P<0.01). Besides, the hemostatic bandage group was significantly better than the hemostatic balloon compressor group with statistically significant differences in wound pain at immediate postoperative ( U=13 669.50, P<0.01), in finger numbness at immediate postoperative and 1-hour postoperative (immediate postoperative: U=17 838.00, P<0.05; 1-hour postoperative: U=13 342.50, P<0.01), in comfort at immediate postoperative, 4-hours, 8-hours and 12-hour postoperative(immediate postoperative: U=9 966.50, P<0.01; 4-hour postoperative: U=12 851, P<0.01; 8-hour postoperative: U=14 900, P<0.01; 12-hour postoperative: U=15 920, P<0.01). Conclusions:The hemostatic bandage shows better hemostatic effect, shorter compression time, lower complication rate, less wound pain, less numbness of the finger on the operation side, and higher comfort of the wrist band compared to hemostatic balloon compressor after transradial coronary angiography and/or interventional therapy, which is worthy of clinical promotion.

Objective:To apply the best evidence for the prevention of radial artery occlusion after transradial coronary angiography or intervention to clinical practice and evaluate its effect.Methods:This was a quasi-experimental study. Based on the evidence continuous quality improvement model, evidence-based practice method was used to obtain the best evidence, formulated review indicators, analyzed the obstacles in the practice process and took action strategies. The 88 patients who underwent transradial coronary angiography or intervention in the Cardiology Department of Qilu Hospital of Shandong University (Qingdao) from June 1 to 30, 2020 were selected as the baseline review group by convenience sampling. The 94 patients who underwent this treatment from September 1 to 30, 2020 were selected as the evidence application group. The baseline review group used the original perioperative management plan, and the evidence application group used the perioperative management plan based on the best evidence. The implementation rate of each review indicator, the incidence of radial artery occlusion, the degree of compression pain, and the comfort level of patients were compared between the two groups.Results:The implementation rates of review indicators 1, 2, 3, 5, 6, 7, 8 in the evidence application group were 100.0% (94/94), 100.0% (94/94), 11.7(11/94), 88.3% (83/94), 100.0% (94/94), 100.0%(94/94), 85.1%(80/94), respectively, which were higher than those in the baseline review group(all 0), except for the review indicator 4, the differences were statistically significant ( χ2 values were 9.00-178.02, all P<0.05). The incidence of radial artery occlusion and the incidence of pain Numerical Rating Scale>3 points in the evidence application group were 2.1% (2/94) and 3.2% (3/94), respectively, which were lower than 14.8% (13/88) and 23.9% (21/88) in the baseline review group; the comfort level of patients in the evidence application group was 96.8% (91/94), which was higher than 63.6% (56/88) in the baseline review group. The differences were statistically significant ( χ2 = 8.01, 15.21, 30.10, all P<0.05). Conclusions:The best evidence for the prevention of radial artery occlusion after transradial coronary angiography or intervention can be applied to clinical practice, which can standardize the behavior of medical staff, reduce the incidence of postoperative radial artery occlusion, reduce the degree of compression pain, and improve the comfort of patients.

Comparison of pain levels of traditional radial, distal radial, and transfemoral coronary catheterization

SUMMARY OBJECTIVE: The aim of our study was to compare the traditional radial artery, distal radial artery, and transfemoral artery, which are vascular access sites for coronary angiography, in terms of pain level using the visual analog scale. METHODS: Between April 2021 and May 2022, consecutive patients from three centers were included in our study. A total of 540 patients, 180 from each of the traditional radial artery, distal radial artery , and transfemoral artery groups, were included. The visual analog scale was applied to the patients as soon as they were taken to bed. RESULTS: When the visual analog scale was compared between the groups, it was found to be significantly different (transfemoral artery: 2.7±1.6, traditional radial artery: 3.9±1.9, and distal radial artery: 4.9±2.1, respectively, p<0.001). When the patients were classified as mild, moderate, and severe based on the visual analog scale score, a significant difference was found between the groups in terms of body mass index, process time, access time, and number of punctures (p<0.001). Based on the receiver operating characteristic analysis, body mass index>29.8 kg/m2 predicted severe pain with 72.5% sensitivity and 73.2% specificity [(area under the curve: 0.770, 95%CI: 0.724-0.815, p<0.0001)]. CONCLUSION: In our study, we found that the femoral approach caused less access site pain and a high body mass index predicts severe pain.

A comparison of the success rate of radial artery cannulation between the ultrasound?guided and conventional palpation techniques in elderly patients undergoing cardiothoracic surgery

Background:Ultrasound?guided (USG) radial artery cannulation against the standard palpation technique increases the first attempt rate in both pediatric and adult patients. The objective of this study was to evaluate the benefits of USG versus the palpation technique in improving the first attempt rate in elderly patients. Methods: The patients over 65 years of age were randomized to the USG or Palpation group. The radial artery identification in the USG group was performed with the aid of the Sonimage HS 1. In the Palpation group, the radial artery was identified by manual palpation. The operators were cardiothoracic anesthesiologists. Overall success was defined as cannulation completed within 10 min. Results: Eighty patients (40 in each group) were recruited. The respective first attempt and overall success rate for the USG group were similar to the Palpation group (P > 0.999 and P = 0.732). The time to the first attempt and overall success were also similar (P = 0.075 and P = 0.636). The number of attempts, number of catheters used, and failure rates were similar between the groups (P = 0.935, P = 0.938, and P = 0.723). The number of successful cannulations within 10 min was similar for both the groups as categorized by the radial artery diameter (P = 0.169). Conclusions: The USG did not increase the first attempt or overall success rate of radial artery cannulation in the elderly patients undergoing cardiothoracic surgery. The time to first attempt and overall success were similar between both the groups. The number of attempts and number of catheters used were similar between both groups.

Assessment and comparison of distal radial artery diameter in anatomical snuff box with conventional radial artery before coronary catheterization

Background: The distal radial artery (dRA) approach at anatomical snuff box has gained attention of the interventional cardiologist in last few years. The procedural success rate by this novel approach depends on size of the radial artery and therefore the study was planned to study the size of distal radial artery. Methods: Total of 1004 patients of >18 years of age undergoing coronary catheterization were included in the study. The vessel diameter was measured from media to media in the anatomical snuff box a day prior to coronary catheterization. Results: The mean diameter of right radial artery at conventional access site was 2.56 ± 0.35 mm and at distal access site 2.23 ± 0.39 mm (p < 0.001). Females had significantly smaller radial artery diameter as compared to males at right conventional access site (2.42 ± 0.36 mm vs 2.60 ± 0.34 mm; p < 0.001) and distal access site (2.09 ± 0.38 mm vs 2.27 ± 0.39 mm; p < 0.001). The diameter of the right dRA was not significantly correlated with age (r2 linear ¼ 0.002, p ¼ 0.0475) but was positively correlated with height and weight (r2 linear ¼ 0.076, p ¼ <0.001 and r2 linear ¼ 0.005, p ¼ <0.001) and negatively correlated with BMI (r2 linear ¼ 0.076, p ¼ 0.519). Conclusions: This study has shown the size of right dRA 2.27 þ 0.39 mm in males and 2.09 þ 0.38 mm in females. Diabetes, hypertension, height and weight are important predictors of dRA diameter

Study of Variations in the Course of Brachial Artery: A Cadaveric Study

Background: Brachial artery begins as a continuation of axillary artery at the distal border of teres major, runs downward at first medial to the humerus and then inclines to lie in front of the bone until it appears in the cubital fossa, where it ends at the level of the neck of radius by dividing into radial and ulnar arteries. Objectives: To know the variations in the course of brachial artery. Methods: Dissection was done on 40 upper limbs from embalmed adult human cadavers in the Department of Anatomy, Kamineni Institute of Medical Sciences, Narketpally. Dissection of Brachial artery was carried out according to Cunningham’s manual of practical anatomy. Results: In all 40 specimens (100%), the brachial artery begins at the inferior border of the teres major muscle as the continuation of the axillary artery. In 37 specimens (92.5%), single brachial artery (BA) was present in the arm. It runs inferiorly on the medial side of the biceps brachii muscle to the cubital fossa. It divides into the radial artery (RA) and ulnar artery (UA) opposite the neck of radius at elbow. In 3 specimens (7.5%), doubling of the brachial artery in its course was observed. In these specimens, the brachial artery was divided into two divisions in the arm. Both divisions runs inferiorly on the medial side of the biceps brachii muscle to the cubital fossa. In these two divisions, one lies superficial to the median nerve and was called the superficial brachial artery (SBA) and other division continues as the brachial artery proper (BAP). In all these 3 specimens (7.5%), the superficial brachial artery (SBA) continued as the radial artery (RA) and brachial artery proper (BAP) continued as the ulnar artery (UA) in the cubital fossa. Interpretation and Conclusion: The present study is important for Surgeons, Orthopedicians, Vascular surgeons, Clinicians and Anatomists as it provides the knowledge of variations in the course of brachial artery in the arm and cubital fossa.

RESUMEN Objetivo: Determinar cuáles fueron los eventos clínicos adversos relacionados con el uso del método femoral y método radial en pacientes que fueron sometidos a procedimientos de cardiología intervencionista en el Hospital Nacional Hipólito Unanue, durante el periodo 2015-2017. Materiales y métodos: La metodología fue comparativa, retrospectiva, con diseño observacional y analítico. Se trabajó con un total de 151 historias clínicas de pacientes que presentaron eventos clínicos adversos. Se empleó la revisión documental como técnica de recolección de datos, y una ficha de recolección de datos como instrumento, la cual fue diseñada por el investigador. Para realizar el análisis se utilizó el programa R. Resultados: De 151 cateterismos cardiacos, el 51,66 % se realizó por el método femoral y 48,34 %, por el método radial. Con respecto a la edad de los pacientes, el promedio fue 59,6 ±11,3 años; el 39,73 % de ellos estuvo entre el rango de 60 a 70 años; y el 73,50 % fueron pacientes del sexo masculino. En cuanto a las comorbilidades, la hipertensión arterial y la diabetes mellitus fueron las enfermedades más recurrentes entre los pacientes. Se presentaron eventos clínicos adversos relacionados con el uso de ambos métodos de acceso vascular, aunque no se consideraron graves; sin embargo, su incidencia es alta. Para la muestra del método femoral, en 50 % de los casos, se presentó hematoma (25,60 %), hemorragia (9 %), isquemia (1,30 %), reacción vagal (1,30 %), pseudoaneurisma (1,30 %), un caso raro tipo quemadura (1,30 %) y dolor (10,20 %); mientras que, en el método radial, en 19,14 % de los casos, se presentó hematoma (8,21 %), hemorragia (2,73 %), espasmo radial (1,40 %) y dolor (6,80 %). Conclusiones: Después de que se determinó cuáles eran los eventos clínicos adversos, se llegó a la conclusión de que es mejor usar el método radial en vez del método femoral para procedimientos de cardiología intervencionista.

ABSTRACT Objective: To determine the clinical adverse events related to the use of femoral and radial artery access in patients who underwent interventional cardiology procedures in the Hospital Nacional Hipólito Unanue from 2015 to 2017. Materials and methods: A comparative, retrospective, observational and analytical study was conducted with a total of 151 medical records of patients who had clinical adverse events. Medical record review was used as data collection technique, and a data collection sheet designed by the researcher was used as instrument. The R software was used for the analysis. Results: Out of 151 cardiac catheterizations, 51.66 % were performed by a femoral artery access and 48.34 % by a radial artery access. The average age of the patients was 59.6 ± 11.3 years, out of which 39.73 % ranged between 60 and 70 years, and 73.50 % of the patients were males. The most frequent comorbidities were arterial hypertension and diabetes mellitus. Non-serious clinical adverse events occurred as a result of both vascular access procedures; however, their incidence was high. Fifty percent (50%) of the patients who underwent a femoral artery access procedure showed the following adverse events: hematoma (25.60 %), bleeding (9 %), ischemia (1.30 %), vagal response (1.30 %), pseudoaneurysm (1.30 %), a rare skin rash that looked like a burn (1.30 %) and pain (10.20 %). In contrast, 19.14 % of the patients who underwent a radial artery access procedure presented hematoma (8.21 %), bleeding (2.73 %), radial artery spasm (1.40 %) and pain (6.80 %). Conclusions: After determining the clinical adverse events, it was concluded that radial artery access is better than femoral artery access for interventional cardiology procedures.

Assessment of postoperative outcomes of radial artery as a sequential graft in coronary artery bypass grafting / 中华胸心血管外科杂志

Objective:To explore the perioperative effect of radial artery as a sequential graft in coronary artery bypass grafting(CABG).Methods:The clinical data and perioperative complications of 109 patients, who underwent radial artery(RA) or great saphenous vein(SVG) as a sequential graft during CABG from April 2020 to December 2020 in Beijing Anzhen Hospital, were analyzed, there were 86 males and 23 females, aged from 39 to 79 years, with an average of(61.1±8.0)years old. According to the graft materials, they were divided into the RA group(n=47) and SVG group(n=62).Results:There were no significant differences between the two groups in age, gender, comorbidities, echocardiographic results, transplant vascular indexes, coronary angiography results, and operation methods(on-pump or off-pump, use of left internal mammary artery, number and distribution of distal anastomoses)( P>0.05). There were also no significant difference between the two groups in ICU stay, postoperative hospital stay and drainage with 24 hours after CABG( P>0.05). The incidence of postoperative cerebrovascular events, postoperative infection and secondary thoracotomy in the RA group were higher than that in the SVG group. The incidence of myocardial infarction, postoperative ventricular arrhythmia and postoperative IABP assistance in the SVG were higher than that in the RA group, but the difference was not statistically significant( P>0.05). Conclusion:The application of radial artery as a sequential graft during CABG does not increase the risk of perioperative complications, and the patients recover smoothly.

Reconstruction of defects of distal-and-middle segments of finger pulps with striated wrist transverse flap carrying superficial palmar branch of radial artery with sensory nerve / 中华显微外科杂志

Objective:To evaluate the clinical effect of striated free wrist transverse flap pedicled with superficial palmar branch of radial artery carrying sensory nerve in repairing pulp defect of middle-and-distal segments of fingers.Methods:From February 2019 to March 2021, the data of 20 patients with defects of middle-and-distal finger segment were collected. The defects were repaired with striated free wrist transverse flaps pedicled with superficial palmar branch of radial artery. The defects sized were 2.0 cm×1.5 cm-4.0 cm×1.5 cm, and the flaps sized were 2.5 cm×2.0 cm-4.5 cm×2.0 cm. The flap carried metacarpal cutaneous branch of median nerve for the reconstruction of the sensation of finger pulps. The donor sites were directly sutured. After operation, the patients were evaluated according to the shape, sensation and functional recovery of the repaired fingers through outpatient visits and reviews via WeChat.Results:All 20 flaps survived and the wounds healed well. All patients entered regular follow-up for 6-12(average, 8) months. The colour of the flaps was close to the finger skin, without bloating flaps. The flaps were soft in good shapes and function. TPD were 6-11 mm, at 8 mm in average. The scars at the donor sites were hidden and the wrist function was not affected. According to the Trial Evaluation Standard of Upper Limb Function of Hand Surgery Society of Chinese Medical Association, 16 patients were classified as excellent and 4 as good.Conclusion:The striated transverse wrist flap with radial artery palmar superficial branch and sensory nerve offers many advantages, such as a good texture, hidden donor site, convenient flap harvesting, good recovery of sensation, etc. More clinical studies and the promotion of the technique are expected.

Efficacy of different compression methods for hemostasis at the radial artery puncture point after percutaneous coronary intervention / 中国基层医药

Objective:To compare the hemostatic effects and patient comfort of different compression methods for hemostasis after transradial coronary intervention.Methods:A total of 160 patients who received transradial coronary intervention in The Affiliated Hospital of Hangzhou Normal University from October 2018 to February 2020 were included in this study. In group A ( n = 80), patients underwent spiral compression at the puncture point (release for 1 turn at 2 hours after surgery, rotation for 1 circle after 1 hour, and full decompression). In group B ( n = 80), patients underwent spiral compression at the puncture point (release for 1 turn at 2 hours after surgery, rotation for 1 circle after 2 hours, and full decompression). Percutaneous arterial oxygen saturation value in the affected limb, heart rate, and Visual Analog Scale score at different times after surgery, pain and comfort score at 2 and 12 hours post-surgery were compared between the two groups. Results:Percutaneous arterial oxygen saturation value at 4 and 12 hours post-surgery in group A was (96.6 ± 0.7)% and (97.8 ± 0.5)%, respectively, which was significantly higher than that in group B [(96.2 ± 0.6)%, (97.6 ± 0.7)%, t = 3.88, 2.08, both P < 0.05]. There were no significant differences in total score and subscale score of the General Comfort Questionnaire at 2 hours post-surgery between groups A and B (both P < 0.05). At 12 hours post-surgery, scores of psychological and physical subscales and total score of the General Comfort Questionnaire in group A were (23.64 ± 3.02) points, (12.64 ± 2.05) points, (68.25 ± 6.04) points, which were significantly higher than those in group B [(22.20 ± 2.96) points, (11.38 ± 2.47) points, (64.42 ± 6.71) points, t = 3.05, 3.51, 3.79, all P < 0.05]. At 2 hours post-surgery, there was no significant difference in Numerical Rating Scale score between groups A and B ( P > 0.05). At 4 and 12 hours post-surgery, Numerical Rating Scale score in group A was (2.51 ± 0.58) points and (1.75 ± 0.76) points, respectively, which was significantly lower than that in group B [(2.95 ± 0.63) points, (2.31 ± 0.71) points, t = -4.59, -4.82, both P < 0.05). The incidence of complications was significantly lower in group A than in group B (8.75% vs. 20.00%, χ2 = 4.11, P < 0.05). Conclusion:Compression for hemostasis is highly effective by releasing for 1 turn at 2 hours after transradial coronary intervention, rotating for 1 circle after 1 hour, and full compression because it can greatly mitigate pain, ensure the oxygen supply to the affected limbs, and improve patient comfort.

Feasibility of a single catheter intervention using the transradial approach for ST-segment elevation myocardial infarction / 中国基层医药

Objective:To evaluate the safety and effectiveness of primary percutaneous coronary intervention using the transradial approach in patients with acute ST-segment elevation myocardial infarction (STEMI) based on electrocardiography results.Methods:The clinical data of 298 patients with STEMI who had indications of emergency coronary angiography and percutaneous coronary intervention who received treatment in The Second People's Hospital of Shantou between January 2015 and June 2019 were retrospectively included in this study. These patients were assigned into traditional transfemoral intervention (TTFI, n = 56), traditional transradial intervention (TTRI, n = 167), and single transradial intervention (STRI, n = 75) groups. Door-to-balloon (D2B) time, needle-to-balloon (N2B) time, hospital days, and the incidence of major adverse cardiac events within 1 year after treatment were compared among the three groups. Results:The D2B time in the STRI, TTFI and TTRI groups was (67.6 ± 2.1) minutes, (73.3 ± 15.3) minutes, and (77.4 ± 16.7) minutes, respectively. There was a significant difference in D2B time among the three groups ( F = -2.24, P = 0.013). The D2B time was significantly shorter in the STRI group than in the TTFI and TTRI groups ( t = -1.84, -1.84, both P = 0.033). The N2B time in the STRI, TTFI and TTRI groups was (7.6 ± 2.1) minutes, (15.3 ± 6.5) minutes, and (14.1 ± 5.7) minutes, respectively. There was a significant difference in N2B time among the three groups ( F = -4.34, all P < 0.001). The N2B time was significantly shorter in the STRI group than in the TTFI and TTRI groups ( t = -2.06, P = 0.020; t = -3.12, P < 0.001). The proportion of patients with D2B time less than 90 minutes in the STRI group was 74.7% (56/75), which was significantly higher than that in the TTRI [46.1% (77/167)] and TTFI [51.8% (29/56)] groups ( χ2 = 4.07, P < 0.001). The incidence of major adverse cardiac events within 1 year after treatment in the TTFI, TTRI, and STRI groups was 16.1% (9/56), 13.2% (22/167), and 9.3% (7/75), respectively. The incidence of major adverse cardiac events within 1 year after treatment was significantly lower in the STRI group than in the TTFI and TTRI groups ( χ2 = 5.67, P < 0.05). Conclusion:STRI is safe and effective for STEMI and is expected to improve long-term prognosis.

Effects of wrist hand thumb joint fixtures in infants to prevent the unplanned extubation of radial artery manometric tube in children with congenital heart disease / 中国实用护理杂志

Objective:To understand clinical effect of a homemade infants wrist hand thumb joint fixtures to prevent the unplanned extubation (UEX) in radial arterial puncture tube in children with congenital heart disease.Methods:From October 2016 to October 2019, 150 cases infants patients with simple congenital heart disease in cardiac surgery of the First Affiliated Hospital of University of Science and Technology of China were selected as the research objects, and the radial artery invasive manometric tube was routinely indwelling after operation. Subjects were randomly divided into observation group and control group, with 75 cases in each group. In the observation group, the wrist joint of children was fixed with homemade fixation device. The control group used conventional fixation methods to fix the wrist joint of infants. The incidence of pressure injury and unplanned extubation were compared between the two groups.Results:There was 1 case (1.33%) pressure injury in the observation group and 2 cases (2.67%) in the control group, and there was no statistical significance in the two groups ( P>0.05). The unplanned extubation rate of radial artery pressure tube occurred in 5 cases (6.67%) in the observation group, and lower than that in the control group (17/75, 22.67%) ( χ2=7.67, P<0.01). When children in the state of agitation and very agitation, the incidence of unplanned extubation rate in the observation group was 0 and 4.35%(1/23), lower than that in the control group 15.79%(6/38) and 35.00% (7/20), respectively ( χ2=6.19, 6.64, both P<0.05). With the extension of ICU time, the incidence of unplanned extubation rate was increased. The incidence of unplanned extubation rate was 4.76% (2/42) and 9.09% (3/33) in the observation group and 18.18%(8/44) and 29.03% (9/31) in the control group when ICU time was ≤24 h and>24 h, respectively. The difference was statistically significant ( χ2=5.51, 4.17, both P<0.05). Conclusions:The homemade wrist thumb joint fixtures device for infants does not increase the pressure injury of the fixed part, and can reduce the incidence of unplanned extubation of radial artery manometric tube in children with congenital heart disease.

Distal transradial access for cerebral angiography and neurointervention: a systematic review and meta-analysis / 国际脑血管病杂志

Objective:To investigate the efficacy and safety of distal transradial access for cerebral angiography and neurointervention.Methods:The literature about distal transradial access for cerebral angiography and neurointervention were searched in PubMed, EMbase, the Cochrane Library, CNKI, WanFang Data, and VIP database from January 2015 to September 2021. Two reviewers independently screened the literature and extracted data according to the inclusion and exclusion criteria, evaluated the literature quality according to the Newcastle-Ottawa scale. The R 4.0.5 software was used for meta-analysis.Results:A total of 12 articles with 987 patients were enrolled. All the studies were retrospective design and did not compare with the results of proximal transradial access and transfemoral access. A meta-analysis of the operation success rate and complication rate using a fixed effect model showed that the operation success rate of distal transradial access was 96% (95% confidence interval 95%-97%), and the incidence of minor complications was 3% (95% confidence interval 2%-4%). One patient had serious complications.Conclusion:The distal transradial access is a safe and effective alternative approach for cerebral angiography and neurointervention.
