ABSTRACT

OBJECTIVE@#To evaluate the effectiveness and safety of Rotarex catheter system in treating femoropopliteal artery stenosis accompanied with thrombosis.@*METHODS@#From Jun. 2017 to Dec. 2019, the clinical data of 32 femoropopliteal artery stenosis accompanied with thrombosis cases treated with Rotarex catheter system were retrospectively analyzed. There were 23 males and 9 females aged from 50 to 89 years and the mean age was (70.7±10.3) years. Six cases had acute course of disease (≤2 weeks), 17 cases had subacute course of disease (>2 weeks, ≤3 months), and 9 cases had chronic course of disease (>3 months). Mean lesion length was (23.4±13.7) cm, mean occlusion length was (19.9±13.3) cm, and in-stent occlusion 7 cases. The superficial femoral artery (SFA) was involved in 13 cases, the popliteal artery (PA) was involved in 8 cases, and both SFA and PA were involved in the other 11 cases. All the cases were treated with Rotarex catheter system. When necessary, suction with large lumen catheter was enabled. Residual stenosis was treated with percutaneous transluminal angioplasty (PTA). Drug-coated balloon (DCB) was only used in patients with financial status, and stent was used only when it was necessary. Heparin was used for 24 h after procedures, and after that, antiplatelet agents were used. Doppler ultrasonography was taken during the followed-up.@*RESULTS@#Technical success was 100%, and mean procedure time was (107.4±21.5) min. 8F (1F≈0.33 mm) and 6F Rotarex catheter were used in 27 and 5 cases respectively. In 27 cases, forward flow was obtained immediately after debulking with Rotarex catheter, and in the other 5 cases, suction with large lumen catheters were used. PTA was used in all 32 cases. DCB were used in 8 cases, of which 4 were used in in-stent stenosis. Twelve cases were implanted stents. There were no perioperative deaths. The only one procedure related complication was distal embolism. We took out the thrombus with guiding catheter. In all cases, mean hospital stay were (4.6±1.5) d. The ankle brachial index increased from 0.32±0.15 to 0.86±0.10 after treatment (t=-16.847, P < 0.001). The Rutherford stages decreased significantly (Z=-4.518, P < 0.001). All the patients were followed up for 6.0-36.0 months, and the median time was 16.0 months. 2 cases stopped antiplatelet agents, which resulted in acute thrombosis. Another percutaneous mechanical thrombectomy and PTA were taken in one of them. Two cases died of cardiovascular disease during the follow-up, and no amputation was observed. Target lesion restenosis occurred in 7 cases during the follow-up, and target lesion revascularization (TLR) was taken in two of them.@*CONCLUSION@#In treating femoropopliteal artery stenosis accompanied with thrombosis, Rotarex catheter can remove thrombus effectively, and that can expose underlying lesions and reduce stent use and complications rates. It is a safe and effective method.

ABSTRACT

Objective: To summarize the single center experience of transcatheter aortic valve replacement (TAVR) with a simplified operative protocol. Methods: Consecutive patients who underwent transfemoral TAVR (TF-TAVR) from July 2020 to December 2020 in Fuwai Hospital were retrospectively analyzed. We compared the baseline characteristic, procedure information, 30-day follow-up outcomes of the patients who underwent TF-TAVR without the simplified operative protocol (routine group) or with the simplified operative protocol (simplified protocol group). Results: 93 patients were collected, 42 patients belonging to routine group, 51 patients belonging to simplified protocol group. In simplified protocol group, there were 51 patients planned to use ultrasound-guided femoral access puncture, procedure was successful in all 51 patients (100%). There were 49 patients planned to use the radial artery as the secondary access, procedure was successful in 45 patients (92%). There were 48 patients planned to use the strategy of avoidance of urinary catheter, this strategy was achieved in 35 patients (73%). There were 12 patients planned to use the left ventricular guidewire to pace, procedure was successful in 11 patients (92%). There were no differences in baseline characteristics, major clinical endpoints and 30-day follow-up outcomes between the two groups. Meanwhile, the procedure time ((62.5±17.9)min vs. (78.3±16.7)min, P<0.001), operation room time ((133.7±25.1)min vs. (159.2±42.6)min, P<0.001), X-ray exposure time ((17.2±6.5)min vs. (20.2±7.7)min, P=0.027) were significantly shorten in simplified protocol group compared with the routine group. Conclusion: Our study results indicate that the simplified operative protocol of TF-TAVR is as effective and safe as the routine operative protocol, meanwhile using the simplified operative protocol can significantly increase the operative efficiency of TF-TAVR.

ABSTRACT

Introducción: La arteria femoral común y sus ramas suministran la mayor parte del flujo sanguíneo al muslo, así como a la totalidad de la pierna y el pie, lo que da lugar a la mayor rama del triángulo femoral: la arteria femoral profunda. Objetivo: Exponer la efectividad de la profundaplastia femoral en la "era endovascular". Reporte del caso: Se presenta un caso de enfermedad arterial periférica de múltiples sectores, sin criterio de cirugía revascularizadora (derivación protésica aorto bifemoral). El paciente manifestaba claudicación intermitente a menos de 30 metros, localizada en pantorrilla derecha. En el estudio hemodinámico se apreciaron los índices de presiones tobillo/brazo disminuidos en arteria tibial posterior (0,46) y pedia derecha (0,33). La ecografía doppler del sector femoral derecho evidenció una estenosis de la arteria femoral profunda en su origen, que producía aumento de las velocidades picos sistólicos (479 cm/s), con flujo desorganizado, dilatación posestenótica y oclusión de la arteria femoral superficial en su origen. Se realizó endarterectomía femoral común y profunda con colocación de parche de politetrafloroetileno. El paciente evolucionó sin complicaciones posoperatorias. En el seguimiento se observó mejoría clínica en relación con la distancia de claudicación y un aumento de los índices de presiones tobillo/brazo en arteria tibial posterior y pedia derecha (0,50), respectivamente. Conclusiones: La profundaplastia femoral, aún en la "era endovascular", permanece como un proceder eficaz que resulta alternativa de tratamiento revascularizador en la enfermedad arterial periférica de localización infrainguinal(AU)


Introduction: The normal femoral artery and its branches supply most of the blood flow to the thigh, as well as to the whole leg and foot, which forms the largest branch of the femoral triangle: the deep femoral artery. Objective: Show the effectiveness of femoral deep plasty in the "endovascular era". Case report: It is presented a case of peripheral artery disease in multiple sectors, without surgical criteria of revascularization (derivación protésica aortobifemoral). The patient presented intermittent claudication in less than 30 meters, and it was located in the right calf. In the hemodynamic study, the ankle-arm pressure indexes were dicreased in the posterior tibial artery (0,46) and right dorsalis pedis artery (0,33). The doppler echocardiography of the right femoral sector confirmed a stenosis in the deep femoral artery in its origin, which produced an increase in the peak systolic velocity (479 cm/s), unorganized flows, poststenotic dilatation and occlusion of the superficial femoral artery in its origin. It was performed a common and deep femoral endarterectomy with colocation of polytetrafluoroethylene patch. The patient evolved without post-surgical complications. In the follow-up, it was observed a clinical improvement in relation with the claudication distance and the increase of the ankle-arm pressure indexes in the posterior tibial artery and right dorsalis pedis artery (0,50), respectively. Conclusions: The femoral deep plasty, still in the ´´endovascular era´´, is an efficient procedure that is an alternative to the revascularization treatment in the peripheral artery disease with infrainguinal location(AU)

ABSTRACT

Abstract With transcatheter aortic valve implantation (TAVI) technology expanding its indications for low-risk patients, the number of TAVI-eligible patients will globally grow, requiring a better understanding about the second-best access choice. Regarding the potential access sites, the transfemoral retrograde route is recognized as the standard approach and first choice according to current guidelines. However, this approach is not suitable in up to 10-15% of patients, for whom an alternative non-femoral access is required. Among the alternative non-femoral routes, the transaxillary approach has received increasing recognition due to its proximity and relatively straight course from the axillary artery to the aortic annulus, which provides a more accurate device deployment. Here we discuss some particular aspects of the transaxillary access, either percutaneously performed or by cutdown dissection.

ABSTRACT

Abstract Background Retroperitoneal open iliac conduits (ROIC) are used in patients with hostile iliac anatomy undergoing endovascular aortic repair (EVAR). Objectives We hereby report our experience of ROIC in patients subjected to EVAR. Methods This was a retrospective evaluation of 8 patients out of a total of 75 patients (11%) who underwent EVAR in the last 10 years. Pre-procedure computed tomography angiography was used to assess the dimensions of iliac and femoral arteries. Patients who had small arterial dimensions (i.e. smaller than the recommended access size for the aortic endograft device) were subjected to ROIC. Results The mean age of the 3 males and 5 females studied was 45.7 ± 15.2 years. The indication for ROIC was the small caliber ilio-femoral access site in 7 patients and atherosclerotic disease in 1 patient. All external grafts were anastomosed to the right common iliac artery except one which was anastomosed to the aortic bifurcation site because of a small common iliac artery. The procedural success rate was 100%. Local access site complications included infection (n=1), retroperitoneal hematoma (n=1), and need for blood transfusion (n=3). The median post-intervention hospital stay was 10 days. All patients had favorable long-term outcomes at a median follow-up of 18 months. Conclusions Female patients require ROIC during EVAR more frequently. Adjunctive use of iliac conduit for EVAR was associated with favorable perioperative and short-term outcomes.


Resumo Contexto Os condutos ilíacos abertos retroperitoneais são utilizados em pacientes submetidos a reparo endovascular de aneurisma (REVA) com anatomia ilíaca hostil. Objetivos Relatamos a nossa experiência com os condutos ilíacos em pacientes submetidos a REVA. Métodos Trata-se de uma avaliação retrospectiva de oito pacientes, de um total de 75 (11%), os quais foram submetidos a REVA nos últimos 10 anos. Foi realizada angiotomografia computadorizada antes do procedimento para avaliar as dimensões das artérias ilíaca e femoral. Os pacientes com dimensões arteriais menores, abaixo do tamanho de acesso recomendado para o dispositivo de endoprótese aórtica, foram submetidos a condutos ilíacos. Resultados A média de idade dos participantes foi de 45,7±15,2 anos, sendo três do sexo masculino e cinco do sexo feminino. As indicações para condutos ilíacos foram local de acesso ilíaco femoral de pequeno calibre, para sete pacientes, e doença aterosclerótica, para um paciente. Todas as próteses externas foram anastomosadas na artéria ilíaca comum direita, com exceção de uma, que foi anastomosada no local da bifurcação aórtica por apresentar artéria ilíaca comum menor. A taxa de sucesso do procedimento foi de 100%. As complicações no local de acesso incluíram infecção (n = 1), hematoma retroperitoneal (n = 1) e necessidade de transfusão de sangue (n = 3). O tempo mediano de internação hospitalar pós-intervenção foi de 10 dias. Todos os pacientes apresentaram desfechos de longo prazo favoráveis no seguimento mediano de 18 meses. Conclusões As pacientes do sexo feminino necessitaram de condutos ilíacos durante REVA com maior frequência. O uso adjuvante de condutos ilíacos com REVA foi associado a desfechos perioperatórios e de curto prazo favoráveis.

ABSTRACT

ABSTRACT Purpose: To evaluate the impact of submersion of the microsurgical anastomosis suture area using saline (0.9% NaCl) in an experimental laboratory during the training of medical students and resident physicians. Methods: Wistar rats (n = 10) were selected to have the two femoral arteries sectioned and anastomosed end-to-end under optical magnification. They were randomly divided, so that on one side suturing was performed under submersion with saline, and the contralateral side was kept dry during the procedure. The surgical times, as well as the patency within 30 min and 72 h of the procedure, were evaluated. Results: Six male Wistar rats survived the surgical anesthetic procedure, with the average initial weight of 243.3 g and the average artery diameter of 0.86 mm, with average time of 15.67 min for the submerged technique and 20.50 min for the dry technique (p = 0.03). The failure rates were 17 and 50% for the submerged group and the dry one, respectively (p = 0.62). Conclusions: Submerged microvascular suture does not compromise the patency of the vessel or increase the time of anastomosis. Therefore, it is a strategy that can be applied by the surgeon according to his/her technical preferences.

ABSTRACT

Objective: To analyse the clinical application of thoracodorsal artery perforator flaps (TDAPF) in the repair of head and neck defects. Methods: A retrospective review was conducted on 38 patients with oral and maxillofacial head and neck malignant tumors who underwent radical resection of oral and oropharyngeal carcinoma and TDAPF repair in the Department of Oral and Maxillofacial Head and Neck Oncology of the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from June 2017 to November 2018. Among them, 32 were males and 6 were females, aged 30-74 years. Flap size, vessel pedicle length, diameter and number of perforators, and flap fat thickness were recorded and counted. Elasti Meter and Skin Fibro Meter were applied to measure the skin elasticity and hardness in the donor areas of 4 kinds of skin flaps before the flap preparation. SPSS 19.0 statistical software was used for statistical analysis of the data. Results: All the flaps survived (100%). The mean elasticity of TDAPF [(41.2±12.9) N/m] was significantly lower than that of anterolateral thigh [(77.6±23.3) N/m, χ²=88.89, P<0.05], anterolateral thigh [(62.6±17.7) N/m, χ²=59.99, P<0.05] and or forearm flap [(51.7±8.6) N/m, χ²=37.82, P<0.05]. The hardness of TDAPF [(0.037±0.016) N] was also significantly lower than that of anterolateral femoral [(0.088±0.019) N, F=93.27, P<0.05], anteromedial femoral [(0.059±0.020) N, F=25.71, P<0.05] or forearm flap [(0.062±0.016) N, F=29.11, P<0.05]. Follow-up period ranged from 2 to 14 months. The 38 patients treated with TDAPF had a good recovery of the functions in the recipient areas, and the scars of the donor areas were not obvious after surgery, without serious complications. Conclusion: TDAPF is suitable for reconstruction of head and neck defect, with ductile texture and good recovery of the morphology and function of head and neck.

ABSTRACT

Objective: To investigate the effects of femoral approach versus radial approach on the incidence of contrast-induced acute kidney injury (CI-AKI) in patients with coronary heart disease, who received twice contrast agents within a short interval. Methods: A total of 322 patients with coronary heart disease, who admitted to the General Hospital of Northern Theater Command from January 2010 to January 2015, were included in this retrospective analysis. All patients exposed to contrast agents twice within 30 days. The patients were divided into two groups according to the approach of interventional operation: radial artery group (n=235) and femoral artery group (n=87). Serum creatinine (SCr) values were detected at 48 and 72 hours post procedure. Endpoint events were CI-AKI, which was defined as SCr increased>0.5 mg/dl (44.2 μmol/L) or relative ratio ((postoperative SCr-preoperative SCr)/preoperative SCr×100%>25%) within 72 hours after contrast agent use after excluding other causes. Clinical characteristics and the incidence of CI-AKI were compared between the two groups, multivariate logistic regression analysis was used to detect the risk factors of postoperative CI-AKI in these patients. Results: The proportion of smoking, PCI history, STEMI patients and levels of fibrinogen, fasting blood glucose, troponin T was significantly higher in femoral artery group than in radial artery group (all P<0.05). The interval between two procedure sessions was significantly longer in the femoral artery group than in the radial artery group (P=0.001). The incidence of CI-AKI tended to be higher in femoral artery group than in radial artery group after the first operation (18.6% (16/87) vs. 11.9% (28/235), P=0.133). CI-AKI incidence after the second operation was similar between the two groups (P>0.05). Multivariate logistic regression analysis showed that interventional approach was not an independent risk factor for postoperative CI-AKI in patients with coronary heart disease undergoing interventional procedures twice within 30 days (P>0.05);STEMI (OR=2.854, 95%CI 1.100-7.404, P=0.031) and diuretics use (OR=4.002, 95%CI 1.470-10.893, P=0.007) were independent risk factors for CI-AKI after the first operation. Conclusion: There is no correlation between the risk of CI-AKI and interventional approaches in patients with coronary heart disease who undergo interventional surgery twice within 30 days.

ABSTRACT

Abstract Purpose: To modify a surgical catheterization method using the bent needle introducer in small animals. Methods: Eight-week-old male Lewis rats were used in the study. A needle introducer was created by bending a 21G injection needle at 45°. The bent needle introducer was used for catheter insertion into the left femoral artery of the rats under anesthesia. As a control, a catheter was directly inserted into the blood vessel without the introducer. The insertion time of each method was measured. Blood pressure and heart rate were measured 24 h after catheter insertion using the telemetry system. Results: Using the introducer, the catheter was successfully inserted within a short time in all rats. Without the introducer, a longer duration was required for catheter insertion. The frequency of the insertion with no catheter-based errors with the introducer tended to be higher than that without the introducer. The mean arterial pressure and heart rate 24 h after catheter insertion in each group were almost the same. Conclusions: We developed a surgical catheterization method using the introducer in small animals. This could potentially reduce the frequency of the insertion with catheter-based errors and insertion time.

ABSTRACT

Abstract Objective: Over the past 10 years, the rate of patients who have undergone coronary artery bypass graft (CABG) surgery has increased twofold in cases of coronary angiography. Today, transradial access is the first choice for coronary angiography. We aimed to compare the efficacy and reliability of radial versus femoral access for coronary angiography in post-CABG surgery in this study. Methods: Data from 442 patients who underwent post-CABG surgery between 2012-2017 were retrospectively compared. The right radial route was used in 120 cases, the left radial route in 148, and femoral route in 174. These three pathways were compared in terms of procedure time and fluoroscopy time, efficacy, and complication development. Comparisons among the three groups were performed with Bonferroni test for continuous variables and chi-square or Fisher's exact test for nominal variables as a binary. Results: Comparison results indicate that femoral access was better than left radial access and the left radial access was better than right radial access in terms of fluoroscopy time (10.71±1.65, 10.94±1.25, 16.12±5.28 min, P<0.001) and total procedure time (17.28±1.68, 17.68±2.34, 23.04±5.84 min, P<0.001). The left radial pathway was the most effective way of viewing left internal mammary artery (LIMA). No statistically significant differences were found among the three groups in other graft visualizations, all minor complications, total procedure and fluoroscopy time "Except LIMA imaging". Mortality due to processing was not observed in all three groups. Conclusion: The left radial route is preferred over right radial access for post-CABG angiography because the left radial pathway is close to the LIMA and is similar to the femoral pathway. In LIMA graft imaging, right radial access is a reliable route, even though it is not as effective as other pathways. We hope that the right radial pathway will improve with physician experience and innovations.

ABSTRACT

El pseudoaneurisma, como lesión arterial tardía, puede evolucionar en periodos prolongados, encontrándose casos tras décadas del desencadenante, sin embargo, es infrecuente encontrarlo luego de 2 años ya que generalmente se logran identificar y resolver antes de este período. Objetivo: Exponer el caso de un pseudoaneurisma de arteria femoral de 15 años de evolución. Métodos: Paciente masculino, con antecedente traumático por herida por arma de fuego complicado con lesión vascular en miembro inferior izquierdo, quien presentó aumento de volumen progresivo y pulsátil en muslo izquierdo de 15 años de evolución, exacerbándose progresivamente con dolor de fuerte intensidad opresivo al caminar en los últimos 5 meses. Examen Físico: disminución de pulsos tibial posterior y pedio, ausencia de pulso poplíteo y anquilosis de la articulación de la rodilla. Resultados: Pseudoaneurisma de arteria femoral izquierda. Intervención Quirúrgica: Exploración vascular, pseudoaneurismectomía, interposición con injerto autólogo contralateral (vena safena). Conclusión: el pseudoaneurisma de la arteria femoral, como lesión arterial tardía, puede presentarse con un cronocidad tan prolongada, que incluso puede sobrepasar una decada, como lo expone el presente caso(AU)


Pseudoaneurysm, as a late arterial injury, can evolve in such long periods, finding specific cases after decades, however, it is infrequent to find it after 2 years, since it is generally possible to identify and resolve it before this period. Objective: to present the case of a 15-year femoral artery pseudoaneurysm. Methods: Male patient, with history of gun shot wound complicated with vascular injury in left lower limb 15 years ago, who had a progressive and pulsating volume increase in the left thigh and intense oppresive pain when walking in the last 5 months. Physical Examination: decreased posterior and pedial tibial pulses, absence of popliteal pulse and ankylosis of knee joint. Results: left femoral artery pseudoaneurysm. Surgical Intervention: Conventional Approach: vascular exploration + pseudoaneurysmectomy + interposition with contralaterial autologous graft (safena vein).

ABSTRACT

Abstract Vascular bypass is a surgical procedure widely used to treat peripheral vascular disease. The intraoperative anesthetic technique and the most appropriate postoperative analgesia for these high-risk patients remain controversial. We present the case of a patient undergoing femoropopliteal-distal bypass in our service, presenting with relevant comorbidities to the choice of anesthetic technique. This patient had several determining factors of difficult airway, especially thoracic kyphoscoliosis, which prevented him from being properly positioned for airway management, and chronic lung disease. This patient was also taken antiplatelet drugs, which is a contraindication for neuraxial block. So, we chose the anesthetic technique of peripheral nerve block, specifically the blockade of femoral and sciatic nerves.


Resumo A cirurgia para bypass vascular é um procedimento amplamente usado para o tratamento da insuficiência vascular periférica. A técnica anestésica para o intraoperatório e para analgesia pós-operatória mais apropriada para esses pacientes de alto risco ainda permanece controversa. Apresentaremos o caso de um paciente submetido a bypass femoropoplíteo distal no nosso serviço, que apresentava comorbidades relevantes para a escolha da técnica anestésica. Esse paciente apresentava fatores determinantes de via aérea difícil, principalmente cifoescoliose da coluna torácica, que o impedia de ser posicionado adequadamente para o manejo da via aérea, além de ser portador de patologia pulmonar crônica. Também fazia uso de antiplaquetários que contraindicavam o bloqueio de neuroeixo. Por isso, optou-se como técnica anestésica pelo bloqueio de nervos periféricos, especificamente o bloqueio dos nervos femoral e isquiático.

ABSTRACT

Aneurismas verdadeiros isolados da artéria femoral superficial (AFS) são eventos raros. Manifestam-se principalmente em homens idosos e frequentemente estão associados a outros aneurismas. Possuem etiologia variada e costumam ser detectados quando apresentam complicações como trombose, embolização distal ou, mais raramente, ruptura. O presente caso refere-se a um paciente cujo aneurisma de AFS se apresentou roto contido e sem associações com outros aneurismas. Foram realizados eco-Doppler colorido arterial, que diagnosticou a ruptura, e angiotomografia, que evidenciou aneurisma sacular de AFS medindo 11,4 × 8,8 cm, com grande trombo mural. Uma arteriografia foi utilizada para programação de revascularização, e detectou-se leito distal via artéria tibial anterior. O paciente foi submetido a revascularização cirúrgica convencional eletiva em artéria femoropoplítea distal com veia safena ipsilateral invertida, com sucesso. Apresentou como complicação pós-operatória infecção de sítio cirúrgico. A pesquisa microbiológica teve resultado negativo, e o estudo anatomopatológico confirmou aneurisma verdadeiro da AFS


Isolated true aneurysms of the superficial femoral artery (SFA) are rare events. They mostly manifest in elderly men and are frequently seen in conjunction with other aneurysms. They have varied etiology and are usually detected when they complicate with thrombosis or distal embolization, or, more rarely, when they rupture. The present case report describes a patient with an aneurysm of the SFA that was ruptured and contained and who had no other aneurysms. Color Doppler ultrasound of the arteries revealed the rupture and angiotomography showed a saccular aneurysm of the SFA measuring 11.4 × 8.8 cm, with a large mural thrombus. Arteriography was used to plan revascularization and showed the distal bed with outflow via the anterior tibial artery. The patient was treated with conventional elective distal femoropopliteal surgical revascularization with the ipsilateral saphenous vein inverted, which was successful. Recovery was complicated by a postoperative surgical site infection. Microbiology tests were negative and the anatomopathological study confirmed a true aneurysm of the SFA

ABSTRACT

Abstract Purpose: To compare the continuous and interrupted suture technique on femoral artery on rats after vessel repair and 14 days after. Methods: Twenty rats were operated randomly divided into two group matched according to the suture technique used: interrupted or continuous. We performed a femoral anastomosis on the right femoral artery. We analyzed weight, arterial caliber, anastomosis time and patency after vessel repair and 14 days after. Results: There was no significant difference between groups in the weight (p=0.64), diameter of the femoral artery (p=0.95) and patency (p=1.00). The time spent in the anastomosis was 451 seconds in the continuous group and 718 seconds in the interrupted group, presenting significant difference (p<0.01). Conclusion: The continuous suture technique shows a similar patency rates than interrupted technique, however with a shorter time to perform the anastomosis.

ABSTRACT

O complexo tratamento de dissecção da aorta ainda apresenta controvérsias devido à gravidade do caso e à necessidade de individualização da terapêutica. A gravidade relaciona-se ao difícil diagnóstico pelas queixas inespecíficas e pelas graves complicações inerentes à evolução da doença (ruptura aórtica, síndrome de má perfusão, dissecção retrógrada, dor ou hipertensão refratária). Este relato apresenta um homem de 61 anos, tabagista e hipertenso mal controlado, que evoluiu para dissecção aórtica de tipo B de Stanford. Foi abordado através de técnica endovascular com uso de endoprótese com stent para tratamento do caso após falha do tratamento medicamentoso. O tratamento endovascular mostrou-se uma ferramenta eficaz para o tratamento definitivo, com boa taxa de sobrevida ao final do primeiro ano após o procedimento


Complex treatment of aortic dissection is still a controversial subject because of the severity of these cases and the need to treat on a case-by-case basis. Severity is related to the difficulty of diagnosis caused by nonspecific complaints and by the serious complications inherent to disease progression (aortic rupture, hypoperfusion syndrome, retrograde dissection, refractory hypertension or pain). This article reports the case of a 61-year-old male smoker with poorly controlled hypertension who suffered a Stanford type B aortic dissection. After drug-based treatment failed, the patient was treated using endovascular techniques to place an endoprosthesis with stenting. Endovascular treatment is proving to be an effective tool for definitive treatment, with a good survival rate at the end of the first year after the procedure

ABSTRACT

Fundamento: A técnica radial reduz a prevalência de complicações vasculares, sangramento grave e mortalidade quando cotejada à técnica femoral. Entretanto, esta ainda predomina como via de acesso preferencial para a efetivação de procedimentos coronários invasivos, requerendo a adoção de estratégias capazes de minimizar intercorrências. Objetivos: Comparar a sobrevida livre de eventos cardiovasculares adversos graves aos 12 meses de pacientes submetidos à estratégia intervencionista precoce pelo acesso radial ou femoral com dispositivo de oclusão vascular. Métodos: Estudo randomizado de não inferioridade envolvendo 240 pacientes com síndrome coronariana aguda sem supradesnível do segmento ST. A função de sobrevivência livre de morte, infarto agudo do miocárdio ou acidente vascular encefálico foi estimada pelo modelo de Kaplan-Meier e comparada utilizando-se o teste de log rank. Resultados: A taxa de complicações vasculares no sítio de punção arterial aos 30 dias foi de 12,5% no grupo Angio-Seal e de 13,3% no grupo radial (p = 1,000). A incidência de sangramento grave ou transfusão sanguínea aos 12 meses também não diferiu entre os grupos (2,5% versus 1,7%, p = 1,000). Não se observou diferença quanto à curva de sobrevida livre de eventos cardiovasculares adversos graves (90,8% versus 94,2%, p = 0,328). Conclusões: Não houve distinção entre as técnicas na sobrevida livre de eventos cardiovasculares adversos graves aos 12 meses de seguimento. Ensaios clínicos com maior poder estatístico são necessários para a validação desses achados


Background: The radial approach reduces the prevalence of vascular complications, major bleeding and mortality when compared to the femoral approach. However, the last still prevails as the preferred approach for the performance of invasive coronary procedures, requiring the adoption of strategies to minimize complications. Objectives: To compare the survival free of major adverse cardiovascular events at 12 months in patients undergoing early intervention strategy by the radial or femoral access with vascular closure device. Methods: Randomized non inferiority trial involving 240 non-ST-segment elevation acute coronary syndrome patients. The survival free of death, myocardial infarction or stroke was estimated by the Kaplan-Meier method and compared using the log rank test. Results: The 30-day rate of vascular complications in the arterial puncture site was 12.5% in the Angio-Seal group and 13.3% in the radial group (p = 1.000). The 12-month incidence of major bleeding or blood transfusion did not differ between groups (2.5% vs. 1.7%, p = 1.000). There was no difference in survival free of major adverse cardiovascular events (90.8% versus 94.2%, p = 0.328). Conclusions: There was no distinction between the techniques in survival free of major adverse cardiovascular events at 12 months of followup. Clinical trials with greater statistical power are needed to validate these findings

ABSTRACT

Contexto: Os dispositivos de oclusão vascular (DOV) permitem rápida remoção da bainha introdutora de um acesso arterial, reduzindo o tempo de hemostasia, a restrição do paciente ao leito e as complicações no sítio de punção. Objetivos: Avaliar a eficácia e possíveis complicações do uso de dispositivo de oclusão arterial comparado com a compressão manual. Métodos: Estudo longitudinal prospectivo randomizado com 20 pacientes no período de dezembro de 2014 a julho de 2015 em Maringá (PR). Foram divididos em dois grupos: aqueles que utilizaram DOV (grupo DOV) e aqueles submetido apenas a compressão manual (grupo CM). Realizaram-se exames de ultrassom Doppler para avaliar a espessura pele-artéria pré e pós-procedimento e verificou-se o tempo de compressão e de deambulação. Os dados foram analisados pelo Programa Statistical Analysis Software. Resultados: Um total de 60% dos pacientes eram do sexo masculino e a média de idade de ambos os grupos foi de aproximadamente 60 anos. Não houve diferença na espessura pele-artéria entre os grupos. O tempo de compressão no grupo DOV foi de 2 minutos e no grupo CM foi de 21±2,11 minutos (p = 0,0005), e o tempo para retorno de movimentos no membro inferior puncionado foi de 2,35±0,75 horas no grupo DOV e de 6 horas no grupo CM (p = 0,0005). Não houve complicações. Conclusões: Neste estudo a hemostasia por compressão manual foi tão efetiva quanto o uso de DOV, embora o tempo de compressão e o tempo para retorno às atividades sejam menores nos pacientes submetidos ao uso do dispositivo


Background: Vascular closure devices (VCD) make it possible to rapidly remove the introducer sheath from an arterial access, thereby reducing the length of time in hemostasis, the time patients are restricted to their beds, and the number of puncture site complications. Objectives: To evaluate the efficacy and possible complications associated with use of an arterial occlusion device compared with manual compression. Methods: This was a prospective, randomized, longitudinal study of 20 patients conducted from December 2014 to July 2015 in Maringá, PR, Brazil. They were divided into two groups: those who were treated using a VCD (VCD group) and those for whom only manual compression was used (MC group). Doppler ultrasound examination was used to determine skin-artery depth before and after the procedure and the length of time compression was maintained and the delay before mobilization were also recorded. Data were analyzed using the program Statistical Analysis Software. Results: A total of 60% of the patients were male and the mean age of both groups was approximately 60 years. There was no difference in skin-artery depth between the groups. The duration of compression in the VCD group was 2 minutes and in the MC group it was 21±2.11 minutes (p = 0.0005), while the delay before return to mobility of the lower limb that had been punctured was 2.35±0.75 hours in the VCD group and 6 hours in the MC group (p = 0.0005). There were no complications. Conclusions: In this study, hemostasis by manual compression exhibited equal efficacy to use of a VCD, but the duration of compression and delay before resumption of activity were shorter in the patients for whom the device was employed

ABSTRACT

Introdução: O Registro Angiocardio, que agrega dados de cinco diferentes centros do Estado de São Paulo, oferece a oportunidade de estudar a associação de fatores de risco cardiovasculares com a extensão da doença arterial coronária (DAC), avaliada pela cinecoronariografia. Este estudo buscou analisar preditores independentes de DAC multiarterial em nosso meio. Métodos: De agosto de 2006 a janeiro de 2014, 16.320 pacientes com DAC foram incluídos e divididos nos grupos uni e multiarterial. Resultados: Pacientes multiarteriais (n = 9.512, 58,3%) apresentaram-se, em média, 3 anos mais idosos, com maior prevalência do sexo masculino (69,4% vs. 65,4%; p < 0,01), hipertensão arterial (80,0% vs. 73,5%; p < 0,01), diabetes (40,7% vs. 28,8%; p < 0,01), dislipidemia (39,6% vs. 34,9%; p < 0,01), antecedentes familiares de DAC precoce (23,0% vs. 21,3%; p < 0,01), insuficiência renal crônica (4,1% vs. 2,6%; p < 0,01), acidente vascular cerebral prévio (3,8% vs. 2,8%; p < 0,01), doença vascular periférica (4,0% vs. 3,3%; p = 0,02) e infarto do miocárdio prévio (18,4% vs. 13,9%; p < 0,01), além de menor prevalência de tabagismo (20,0% vs. 24,5%; p < 0,01). À análise multivariada, foram preditores independentes de lesão multiarterial idade > 40 anos (odds ratio - OR = 1,996; IC 95% 1,52-2,63; p < 0,01), sexo masculino (OR = 1,202; IC 95% 1,12-1,28; p < 0,01), hipertensão arterial (OR = 1,439; IC 95% 1,34-1,55; p < 0,01), diabetes (OR = 1,697; IC 95% 1,59-1,81; p < 0,01), dislipidemia (OR = 1,223; IC 95% 1,15-1,30; p < 0,01), infarto agudo do miocárdio prévio (OR = 1,393; IC 95% 1,28-1,52; p < 0,01) e insuficiência renal crônica (OR = 1,597; IC 95% 1,33-1,91; p < 0,01). Conclusões: A DAC multiarterial em nosso meio é associada aos fatores de risco tradicionais para aterosclerose, com exceção do tabagismo. A idade, o diabetes e a insuficiência renal crônica foram os fatores preditores mais fortes para a DAC multiarterial avaliada pela cinecoronariografia


Background: The Angiocardio Registry, which comprises data from five different centers in the state of São Paulo, offers the opportunity to study the association between cardiovascular risk factors and coronary artery disease (CAD) extent, as assessed by coronary angiography. This study aimed to evaluate independent predictors of multivessel CAD in Brazil. Methods: From August 2006 to January 2014, 16,320 patients with CAD were included and divided into the single- and multivessel groups. Results: Patients with multivessel disease (n = 9,512, 58.3%) were on average 3 years older, with a higher prevalence of males (69.4% vs. 65.4%; p < 0.01), arterial hypertension (80.0% vs. 73.5%; p < 0.01), diabetes (40.7% vs. 28.8%; p < 0.01), dyslipidemia (39.6% vs. 34.9%; p < 0.01), family history of CAD (23.0% vs. 21.3%; p < 0.01), chronic renal failure (4.1% vs. 2.6%; p < 0.01), previous stroke (3.8% vs. 2.8%; p < 0.01), peripheral vascular disease (4.0% vs. 3.3%; p = 0.02) and previous myocardial infarction (18.4% vs. 13.9%; p < 0.01), as well as a lower prevalence of smoking (20.0% vs. 24.5%; p < 0.01). At the multivariate analysis, the following were independent predictors of multivessel lesion: age > 40 years (odds ratio - OR = 1.996; 95% CI: 1.52-2.63; p < 0.01), male gender (OR = 1.202; 95% CI: 1.12-1.28; p < 0.01), arterial hypertension (OR = 1.439; 95% CI: 1.34-1.55; p < 0.01), diabetes (OR =1.697; 95% CI: 1.59-1.81; p < 0.01), dyslipidemia (OR = 1.223; 95% CI: 1.15-1.30; p < 0.01), previous acute myocardial infarction (OR = 1.393; 95% CI: 1.28-1.52; p < 0.01), and chronic renal failure (OR = 1.597; 95% CI: 1.33-1.91; p < 0.01). Conclusions: Multivessel CAD in Brazil is associated with traditional risk factors for atherosclerosis, except for smoking. Age, diabetes, and chronic renal failure were the strongest predictors for multivessel CAD assessed by coronary angiography
