The Mechanism of Volume Regulation by Cervical Neuroforaminal Veins as was Previously Demonstrated for the Internal Vertebral Venous Plexus (IVVP) in the Cervical and Lumbar Region / Mecanismo de Regulación del Volumen por las Venas Neuroforaminales Cervicales como se Demostró Previamente para el Plexo Venoso Vertebral Interno (PVVI) en la Regiones Cervical y Lumbar

SUMMARY: Head and cervical spine movements cause narrowing or widening of neuroforamina. In healthy individuals these movements do not cause symptoms of radiculopathy. This implies a compensating volume-regulating mechanism of the neuroforamina. Such a mechanism has been postulated in the years before CT and MRI for the neuroforaminal veins. Dural sac indentations with emptying and refilling of the internal vertebral venous plexus (IVVP) were postulated in the lumbar region using myelography. Emptying of the IVVP occurs in the lumbar spine when moving towards maximal extension and refilling while moving towards maximal flexion. Such indentations have not been shown in the cervical region. With MRI this mechanism has been demonstrated during axial rotation in the C1-C2 segment. It consists of emptying and refilling of the IVVP and thus prevents dural sac compression. During spinal surgery, the IVVP and connecting neuroforaminal veins may be damaged. Because the clinical implications of dysfunction of this protecting mechanism of the IVVP and its neuroforaminal venous connections are not clear, the consequences of such damage are unknown. Therefore, these venous structures should be examined by studying the cervical spine in supine position and, if possible, in different postures (flexion, extension and axial rotation) using MRI with contrast-enhancement and fat suppression. These images may be a basis for future advancement of clinical care.

Los movimientos de la cabeza y la columna cervical provocan un estrechamiento o ensanchamiento de las neuroforaminas. En individuos sanos estos movimientos no causan síntomas de radiculopatía. Esto implica un mecanismo compensador de regulación del volumen de las neuroforaminas. Este mecanismo se ha postulado en los años anteriores a la TC y la RM para las venas neuroforaminales. Mediante mielografía se postularon hendiduras del saco dural con vaciado y llenado del plexo venoso vertebral interno (PVVI) en la región lumbar. El vaciado del PVVI se produce en la columna lumbar cuando se mueve hacia la máxima extensión y se rellena mientras se mueve hacia la máxima flexión. En la región cervical no se han observado tales depresiones. Con resonancia magnética se ha demostrado este mecanismo durante la rotación axial en el segmento C1-C2. Consiste en vaciar y rellenar la PVVI y así evitar la compresión del saco dural. Durante la cirugía de columna, la PVVI y las venas neuroforaminales que las conectan pueden dañarse. Debido a que las implicaciones clínicas de la disfunción de este mecanismo protector de la PVVI y sus conexiones venosas neuroforaminales no están claras, se desconocen las consecuencias de dicho daño. Por tanto, estas estructuras venosas deben examinarse estudiando la columna cervical en decúbito supino y, si es posible, en diferentes posturas (flexión, extensión y rotación axial) mediante resonancia magnética con contraste y supresión grasa. Estas imágenes pueden ser una base para futuros avances de la atención clínica.

Anatomical Study of the Cardiac Veins and their Tributaries in Bovines (Bos indicus) in Comparison with Humans and Other Animal Species / Estudio Anatómico de las Venas Cardiacas y sus Tributarias en Bovinos (Bos indicus) en Comparación con Humanos y Otras Especies Animales

SUMMARY: In bovines, anatomical observations of the coronary vascular tree describe qualitative characteristics. The objective of this study was to morphometrically characterize the coronary veins and their tributaries in cattle. An arcuate application with 2.0 silk was performed around the ostium of the coronary sinus of 28 bovine hearts and a number 14 catheter was placed, through which semi- synthetic polyester resin and mineral blue color was perfused. In 22 hearts (78.6 %) the great cardiac vein was originated at the cardiac apex. The configuration of the arteriovenous trigone was mainly closed inferior and superior types (50 %). The caliber of the great cardiac vein at the level of the atrioventricular sulcus was 6.7 +/- 1.2 mm. The origin of the left marginal vein was observed in the lower third of the left cardiac margin (53.6 %), its distal caliber was 4.1 +/- 0.8 mm and its drainage was at the level of the great cardiac vein. The middle cardiac vein originated from the cardiac apex in 78.6 % of the samples, emptied mainly into the coronary sinus (82.1 %) and its distal caliber was 4.7 +/- 0.9 mm. Anastomoses occurred in 28.6 % of the hearts, being found in most cases between the middle cardiac vein and the great cardiac vein (50 %), which was significant compared to other anastomoses (p<0.001). The length of the coronary sinus was 42.2 +/- 5.1 mm, its distal caliber was 13.8 +/- 2 mm, and its shape was cylindrical. Myocardial bridges were found in 3 hearts (10.7 %) mainly in the lower third of the middle cardiac vein (66.6 %). Most of the main coronary veins drained into the coronary sinus, with some cases with atypical outlets and the presence of a high percentage of anastomosis that serves to improve cardiac venous drainage in case of venous compression or obstruction.

En bovinos, las observaciones anatómicas de árbol vascular coronario describen características cualitativas. El objetivo de este estudio fue caracterizar morfométricamente las venas coronarias y sus tributarias en bovinos. Se realizó una aplicatura arciforme con seda 2.0 alrededor del ostium del seno coronario de 28 corazones de bovino y se colocó un catéter número 14, a través del cual se perfundió resina de poliéster semisintética y color azul mineral. La vena cardiaca magna se originó en 22 corazones (78,6 %) en el ápex cardiaco. La configuración del trígono arteriovenoso fue principalmente cerrado inferior y superior (50 %). El calibre de la vena cardiaca magna a nivel del surco atrioventricular fue 6,7 +/- 1,2 mm. El origen de la vena marginal izquierda se observó en el tercio inferior del margen izquierdo cardiaco (53,6 %), su calibre distal fue 4,1 +/- 0,8 mm y su desembocadura fue a nivel de la vena cardiaca magna. La vena cardiaca media se originó en el ápex cardiaco en el 78,6 % de las muestras, desembocó principalmente en el seno coronario (82.1 %) y su calibre distal fue 4,7 +/- 0,9 mm. Se presentó anastomosis en el 28,6 % de los corazones, encontrándose en la mayoría de los casos entre la vena cardiaca media y la vena cardiaca magna (50 %), lo cual fue significativo en comparación con otras anastomosis (p<0,001). La longitud del seno coronario fue 42,2 +/- 5,1 mm, su calibre distal fue 13,8 +/- 2 mm y su forma fue cilíndrica. Se encontró puentes miocárdicos en 3 corazones (10,7 %) y en el tercio inferior de la vena cardiaca media (66,6 %). La mayoría de las venas coronarias principales desembocan en el seno coronario, con algunos casos con desembocaduras atípicas y la presencia de un alto porcentaje de anastomosis que sirve para mejorar el drenaje venoso cardiaco en caso de compresión u obstrucción venosa.

ABSTRACT Introduction: The clinical, etiological, anatomical and pathophysiological classification (CEAP) standardizes the manifestations of lower limb venous disease. Objetive: To investigate the association between insufficient venous systems and the clinical classification of CEAP. Method: A quantitative, cross-sectional, analytical, correlational design was carried out. Non-probability sampling for convenience. Sample size was 136 lower limbs from 71 patients. Chi-square, Monte Carlo and Odd ratio (OR) statistical tests were used with 95% confidence intervals through bivariate logistic regression (p<0.05). Results: 71.8% were female, average age of 66.1. The most frequent insufficient venous system was the superficial one (61.7%). 100% of the dilated great saphenous veins (GSV) had insufficiency. The most frequent CEAP clinical class was C2: 44.9%); 35.1% of C1 (telangiectasia) had an insufficient venous system and 50% of C2 had GSV insufficiency (p=0.227). There was an association between insufficiency of the superficial and deep venous systems and the CEAP clinical classification (p=<0.001). The deep venous system was associated with severe chronic venous disease of the lower limbs OR (6.04) with 95% CI (1.02-35.73) and p=0.047. Conclusions: An association was evident between the insufficiency of the superficial and deep venous systems with the clinical classification of CEAP. One third of lower limbs with C1 (telangiectasias) had an insufficient venous system.

Risk factors of supplementary injection after foam sclerotherapy for varicose veins of lower extremities and its impact on blood coagulation function / 实用医学杂志

Objective To explore the risk factors of supplementary injection after foam sclerotherapy for varicose veins of lower extremities and its impact on blood coagulation function.Methods A total of 185 patients with varicose veins of lower limbs diagnosed in the First People's Hospital of Zunyi from January 2018 to December 2021 were selected.The corresponding pathological data were collected,and the D-dimer,thrombin time,and fibrinogen level of patients were detected 1 d before and 1 d after the surgery.The postoperative video phone follow-up lasted until 6 months after the surgery.The patients were divided into single treatment group and supple-mentary treatment group according to whether supplementary injection of foam sclerosing agent was needed during the follow-up.Propensity matching on the data between the two groups was conducted,and the correlation between disease course data,coagulation factors,and the occurrence of supplementary injection was analyzed.A time series model for the incidence of supplementary injection was established,and the therapeutic effect and complica-tions were observed.Results After propensity matching,there was still significant difference in the degree of lesion between the two groups(P<0.05).On the first day after surgery,there was significant difference in the D-dimer and fibrinogen groups between the two groups(P<0.05),and but no significant difference in thrombin time(P>0.05).The occurrence of supplementary injection was significantly correlated with D-dimer,fibrinogen,thrombin time,and first-time injection dose(P<0.05),and the incidence of supplementary injection was higher in patients who received first-time injection in January,August,September,and December.Both groups achieved successful treatment 6 months after surgery,and there was no significant difference in the incidence of compli-cations.Conclusion Patients with lower limb varicose veins of C3/C4 are more likely to require supplementary injection compared to patients with other levels.The level of D-dimer and fibrinogen at 1 d after surgery is positively correlated with the occurrence of supplementary injection,while the dose of the first injection is negatively corre-lated with the occurrence of supplementary injection.

Polidocanol-foam treatment of varicose veins: Quality-of-life impact compared to conventional surgery

Abstract Background and objective: Lower limb varicose veins are a prevalent disease associated with several available treatment options, including conventional surgery and polidocanol foam sclerotherapy. However, few studies have analyzed therapeutic modality outcomes based on Patient-Reported Outcome Measures (PROMs). This large sample-size study was designed to evaluate the outcomes of polidocanol foam sclerotherapy compared to conventional surgery based on an analysis of PROMs. Methods: This was a prospective, observational, and qualitative study of 205 patients who underwent varicose vein treatment with either polidocanol foam sclerotherapy (57 patients, 90 legs) or conventional surgery (148 patients, 236 legs). Patients were preoperatively assessed and re-evaluated 30 days after the procedure using the Venous Disease Severity Score (VCSS) and specific venous disease quality-of-life questionnaires (VEINES-QoL/Sym). Results: Both treatments significantly improved VCSS and VEINES results 30 days after the procedure (p < 0.05). However, surgery promoted greater improvements in VCSS (on average 4.02-points improvement, p < 0.001), VEINES-QoL (average 8-points improvement, p < 0.001), and VEINES-Sym (average 11.66 points improvement, p < 0.001) than did sclerotherapy. Postoperative pain and aesthetic concerns about the legs were the domains of the questionnaires in which the results varied the most between the treatment modalities, with worse results for sclerotherapy. Conclusion: Both polidocanol foam sclerotherapy and conventional surgery positively impact patients' quality of life after 30 days, but the improvement is more significant for patients who undergo conventional surgery.

Thermoablative treatment of tributary veins with multiple puncture sites expands the applications for endolaser in treatment of lower limb varicose veins, providing, comprehensive, safe, and effective treatment.

Abnormal communication between cephalic and basilic veins-a case report

The cephalic vein and basilic vein begin respectively from lateral and medial ends of the dorsal venous arch of hand. The basilic vein is confined to the medial side of upper limb and continues upwards as the axillary vein whereas the cephalic vein is confined to the lateral side of upper limb and drains into the axillary vein. The aforesaid veins communicate with one another through the median cubital vein that lies in the roof of cubital fossa. The superficial veins are used for venepuncture, cardiac catheterization, bypass grafting and arteriovenous fistula for hemodynamic access. The authors chanced upon a variation in the cephalic and basilic veins in the right upper limb of a cadaver of a sixty years old female dying due to natural causes. The cadaver was used for routine dissection classes of first year MBBS students in a medical college of Eastern India. The cephalic and basilic veins of the said cadaver joined with each other in the cubital fossa. The brachial vein began from the point of union of the two former superficial veins and the single brachial vein replaced the paired brachial veins which is usually the norm.

Morphological Study of Small Cardiac Vein, Right Marginal Vein, Posterior Vein of the Left Ventricle, Left Marginal Vein, Oblique Vein of Marshall, and Anterior Cardiac Veins in Human Hearts of Western Region of U.P – Clinical Implication

Introduction:Cardiac venous system is an important system for various cardiac interventional procedures such as cardiac catheterization. Various veins like right marginal vein, small cardiac vein (SCV), posterior vein of the left ventricle, left marginal vein, oblique vein of Marshall drain into coronary sinus. While anterior cardiac veins drain right ventricular wall directly into right atrium. Materials and Methods: An observational cross‑sectional study was conducted on thirty cadaveric hearts during a 2‑year period in Shri Ram Murti Smarak Institute of Medical Sciences, Bareilly, Anatomy Department. The length, diameter of SCV, left marginal vein, posterior vein of the left ventricle, right marginal vein, and oblique vein of Marshall were taken. Results: The study reveals the length of SCV as 28.12 ± 22.87 mm. The length of right marginal vein and posterior vein of the left ventricle is having a significant correlation with age. The length of oblique vein of Marshall is lower in males as compared to females. A number of ACVs were significantly related to weight of cadaver in males. Conclusions: The present study provides data of cardiac veins for various cardiac interventional procedures.

Comparison between Wright and Shukla formulas: which is better for the placement of umbilical catheters in newborns ≤ 1500 g? / Comparación entre las fórmulas de Wright y de Shukla: ¿cuál es mejor para la colocación de catéteres umbilicales en recién nacidos ≤ 1500 g?

Abstract Background: Intravascular venous (VUC) or arterial (AUC) umbilical catheter placement is the most frequent invasive procedure in the neonatal intensive care unit (NICU). Either Wright's or Shukla's formula is used to introduce the catheters. However, Shukla's formula is associated with incorrect insertion, especially for newborns < 1500 g. This study aimed to determine by chest X-ray if Wright's formula is better than Shukla's formula for the correct placement of umbilical catheters in newborns ≤ 1500 g. Methods: We included patients admitted to the NICU of a secondary-level hospital between 2021-2022 who received VUC or AUC through the Wright or Shukla formulas. Results: A total of 129 newborns were included: 78 with VUC and 51 with AUC. In VUC, 50% with Wright and 36.8% with Shukla formulas had the correct location, (p = 0.24). In AUC, 56.6 % with Wright and 52.4% with Shukla formulas were placed correctly placed, (p = 0.76). VUC with weight < 1000 g were correctly placed in 36.4% with Wright and 33.3% with Shukla formulas (p = 0.58). VUC in newborns > 1000 g were correctly placed in 66.6% with Wright and 38.4% with Shukla formulas (p = 0.065). AUC in newborns < 1000 g were correctly placed in 45% using Wright and 42.9% Shukla formulas (p = 0.63). AUC in newborns > 1000 g were correctly placed in 80% using Wright and 57.1% Shukla formulas (p = 0.23). Conclusions: We found 13% more correctly placed VUC using Wright's formula. Moreover, Wright's formula was 29% above Shukla's VUC placement in neonates > 1000 g, although there was no significant difference due to the sample size.

Resumen Introducción: La colocación de catéteres intravasculares venosos umbilicales (CVU) y arteriales (CAU) es el procedimiento invasivo más frecuente en la unidad de cuidados intensivos neonatales (UCIN). Para introducirlos se utilizan las fórmulas de Wright y de Shukla, aunque esta última podría estar asociada con una inserción incorrecta, especialmente en neonatos < 1500 g. El objetivo de este estudio fue determinar mediante radiografía de tórax cuál fórmula es mejor para la correcta colocación de catéteres umbilicales en recién nacidos ≤ 1500 g. Métodos: Se incluyeron los pacientes ingresados en la UCIN de un hospital de segundo nivel entre 2021-2022 que recibieron CVU o CAU mediante las fórmulas de Wrigth o Shukla. Resultados: Se incluyeron en total 129 recién nacidos: 78 CVU y 51 CAU. En CVU, Wright 50% y Shukla 36.8% tuvieron localización correcta, p = 0.24. En las CAU, Wright 56.6% y Shukla 52.4% tenían una ubicación correcta, p = 0.76. En CVU con peso < 1000 g, Wright 36.4% y Shukla 33.3% bien situados, p = 0.58. En CVU > 1000 g, Wright 66.6% y Shukla 38.4% bien situados, p = 0.065. En CAU < 1000 g, Wright 45% y Shukla 42.9%, p = 0.63. En CAU con peso > 1000 g, Wright 80% y Shukla 57.1%, p = 0.23. Conclusiones: La colocación del CVU fue 13% mejor con la fórmula de Wright. La fórmula de Wright superó en el 29% la colocación del CVU en los neonatos > 1000 g en comparación con la de Shukla, aunque no hubo diferencia significativa debido al tamaño de la muestra.

Prolonged standing (92.9 percent) was the primary modifiable risk factor, while hypertension was present in the non-modifiable ones (33.8 percent). 40.3 percent reported the use of compression stockings to prevent the progression of the disease. Conclusions: A high incidence of varicose veins was determined in female nursing staff, of advanced age, associated with occupational risk factors such as prolonged standing and sedentary lifestyle(AU)

Effects of maternal anxiety on fetal and maternal circulation

SUMMARY OBJECTIVE: The aim of this study was to evaluate the association between maternal anxiety in the third trimester and changes in fetal and maternal circulation assessed by Doppler velocimetry. METHODS: This is a prospective, cross-sectional study. The inclusion criteria were good health, a singleton pregnancy, maternal age between 18 and 40 years, and gestational age between 34 and 40 weeks. Doppler measurements included mean uterine artery pulsatility index, fetal middle cerebral artery pulsatility index, peak of systolic velocity, umbilical artery, and umbilical vein. The Beck Anxiety Inventory questionnaire, validated for the Brazilian population, with 21 self-reported items, was applied. RESULTS: The study included 34 pregnant women, and 6 (17.7%) presented a total Beck Anxiety Inventory score showing moderate or severe maternal anxiety. The mean maternal age was 28.1 years (SD 5.7 years); the mean gestational age at interview was 36.5 weeks (SD 1.8 weeks), and the mean Beck Anxiety Inventory total score was 12.3 (SD 9.8). The group with moderate or severe anxiety, compared to the group with minimal or mild anxiety, presented an association with lower maternal age (median 21.5 vs. 29.5 years, p=0.019), lower fetal umbilical vein blood flow (median 189.4 vs. 249.5 mL/min, p=0.047), and lower umbilical vein-corrected blood flow (median 68.5 vs. 84.9 mL/kg/min, p=0.038). CONCLUSION: Maternal anxiety may affect fetal circulation patterns in late pregnancy and is associated with reduced blood flow in the fetal umbilical vein. The underlying physiopathology needs further investigation.

Application of cerebral venous drainage imaging evaluation in patients with acute ischemic stroke undergoing endovascular treatment / 国际脑血管病杂志

The cerebral venous system plays an important role in maintaining cerebral blood flow homeostasis. Research has shown that cerebral venous drainage is associated with collateral circulation status and outcomes after endovascular treatment in patients with acute ischemic stroke. There are currently multiple methods for evaluating cerebral veins based on different imaging techniques. This article reviews the imaging evaluation methods for cerebral venous drainage and their application in patients with acute ischemic stroke undergoing endovascular treatment.

The clinical outcomes of endovenous microwave ablation and radiofrequency ablation for great saphenous varicose veins / 中华普通外科杂志

Objective:To compare the efficacy of intraluminal microwave ablation with radiofrequency ablation in the treatment of varicose veins of the lower extremities.Methods:The clinical data of 520 patients (522 affected limbs) who underwent lower extremity varicose vein surgery at the Department of Vascular Surgery of the First Affiliated Hospital of Anhui Medical University from Jun 2021 to Sep 2022 were collected. Patients were divided into endovenous microwave ablation group (EMWA group, n = 201) and radiofrequency ablation group (RFA group, n = 321). Follow-up was performed at 1 week, 1 , 6 and 12 months after surgery. The primary efficacy endpoint was the occlusion rate of the treated segment vein, the primary safety endpoint was the incidence of surgery-related and/or device-related complications, and the secondary endpoints were the venous clinical severity score (VCSS) and chronic venous insufficiency quality of life questionnaire (CIVIQ) scores at follow-up. Results:The technique success rate and the occlusion rate of the affected segment vein was 100% in both groups evaluated one week after surgery; Six and 12 months after surgery, the occlusion rate in the RFA group was 98.9%, and that in the EMWA group was 99.3% and respectively 97.8%, 97.2% ,without statically significant difference.During the follow-up period, there were no cases of reoperation due to vein recanalization. no serious events such as deep vein thrombosis, pulmonary embolism or death occurred in either group. The incidence of adverse events (induration, ecchymosis, skin burn, incision infection, limb numbness, hematoma, thrombotic superficial phlebitis, endovenous heat induced thrombosis, etc.) in both groups was compared, and the difference was not statistically significant. VCSS and CIVIQ scores improved significantly in both groups at 1 ,6 and 12 months after treatment, and the difference was statistically significant(all P < 0.01). Conclusion:EMWA and RFA have the advantages of simple operation, good clinical efficacy and high degree of improvement in quality of life.

Management of primary catheter malposition following totally implantable venous access port implantation via the internal jugular vein / 中华普通外科杂志

Objective:To investigate the characteristics of primary catheter malposition (PCM) following totally implantable venous access port (TIVAP) implantation via the internal jugular vein (IJV) and management strategies.Methods:Clinical data of 587 consecutive breast cancer patients undergoing TIVAP implantation via the IJV performed by single team at the Department of Breast Surgery, the First Affiliated Hospital of Zhengzhou University from Aug 2017 to Aug 2022 was retrospectively analyzed.Results:A total of 593 TIVAP were implanted and PCM was found in 18 cases (3.0%). Four hundred and twenty five TIVAP were implanted via the right IJV with one PCM case (0.2%). One hundred and sixty eight TIVAP implantations were performed via the left IJV and PCM occurred in 17 cases (10.1%). The interventional management with a pigtail catheter was performed as a first-line strategy in 11 of the 18 PCM cases, with a success in 10 cases and failure in one. Three cases were successfully managed with the digital subtraction angiography (DSA)-guided open approach. Four cases underwent blind open procedure firstly and 2 suffered a failure.Conclusions:A higher incidence of PCM is found in TIVAP implantations via the left IJV than the right one. The interventional management with a pigtail catheter or the DSA-guided open procedure proves to be feasible for the correction of PCM.

Randomized controlled trial of endovenous N-butylcyanoacrylate endovenous nonthermal ablation and radiofrequency endovenous thermal ablation for incompetent great saphenous veins / 中华普通外科杂志

Objective:To evaluate the safety and efficacy of n-butyl cyanoacrylate (NBCA) in treating great saphenous vein(GSV) incompetence.Methods:60 patients (60 limbs) with GSV incompetence were randomly divided into NBCA glue group (30 cases) and radiofrequency ablation(RFA) group in 30 cases. The clinical outcomes, venous clinical severity score(VCSS), and quality of life using the Aberdeen varicose vein questionnaire(AVVQ) were evaluated. The primary endpoint is the occlusion rate of GSV at 3 months after surgery.Results:For the two groups, the occlusion rate of GSV was 100% immediately after surgery and at 3 months follow-up. AVVQ and VCSS were improved in the two groups( P<0.05). In terms of complications, the NBCA group had scleroma in 3 cases, pain and skin redness in 1 case respectively, but no ecchymosis and numbness. In the RFA group, numbness occurred in 1 case, skin redness in 2 cases, scleroma in 3 cases, ecchymosis and pain in 4 cases respectively. The incidence of ecchymosis and total complications in the NBCA group was significantly lower than that in the RFA group( P<0.05). No DVT or other adverse event occurred in both groups. Conclusion:NBCA and RFA have the same short-term closure rate. Furthermore, the NBCA treatment requires less equipment, no use of tumescent anesthetic, and has lower incidence in terms of complications than that of RFA.

Incidence and related factors of umbilical venous catheter tip migration / 中华围产医学杂志

Objective:To analyze the incidence and the related factors of umbilical vein catheter (UVC) tip migration within 7 d after umbilical vein catheterization.Methods:This prospective study involved neonates who were successfully indwelled with UVCs in the Department of Neonatology of Gansu Provincial Women and Child-care Hospital from June 2020 to December 2021. The position of the UVC tip, length of umbilical stump, body weight, and abdominal circumference were recorded after the UVCs were inserted successfully, and the changes in these four data at 2, 24, 48, 72 h, and 7 d after catheterization were analyzed and compared. All the subjects were divided into the non-migrate group, inward migration group, and outward migration group. Chi-square test, Mann-Whitney U test, or Kruskal Wallis H test were used for statistical analysis. Results:A total of 157 newborns were enrolled, with 51 cases in the inward migration group, 62 cases in the outward migration group, and 44 cases in the non-migrate group. There were no significant differences among the three groups regarding gestational age, birth weight, gender, born through cesarean section, age at the time of catheterization, use of sedation, and feeding modes (all P>0.05). The migration rates of UVCs tip at 2, 24, 48, 72 h, and 7 d after catheterization were 0, 27.4% (43/157), 27.2% (31/114), 25.3% (21/83), and 29.0% (18/62), respectively. The cumulative migration rates at 24, 48, 72 h, and 7 d were 27.4% (43/157), 47.1% (74/157), 60.1% (95/157), and 72.0% (113/157), respectively. Compared with the non-migrate group, the inward migration group had a shorter umbilical cord stump at 24 and 48 h [0.5 cm (0.4-0.5 cm) vs 0.6 cm (0.5-0.8 cm); 0.4 cm (0.3-0.5 cm) vs 0.5 cm (0.5-0.6 cm), Z=－5.55 and －3.69, both P<0.05], less abdominal circumference increment at 48 and 72 h [0.6 cm (0.5-1.0 cm) vs 0.9 cm (0.7-1.2 cm); 0.6 cm (0.3-0.9 cm) vs 0.9 cm (0.7- 1.3 cm), Z=－2.03 and －2.09, both P<0.05)], and more weight loss percentage [－4.7% (－6.0%-－3.6%) vs －3.1% (－3.7%-－2.2%); －6.0% (－7.5%-－5.0%) vs －3.9% (－5.1%-－2.4%), Z=－3.75 and －2.96, both P<0.05]. The abdominal circumference increased more in the outward migration group at 24, 48, 72 h, and 7 d than those in the non-migrate group [1.6 cm (0.9-1.9 cm) vs 0.7 cm (0.5-0.9 cm); 1.5 cm (1.2-1.8 cm) vs 0.9 cm (0.7-1.2 cm); 1.7 cm (1.3-1.9 cm) vs 0.9 cm (0.7-1.3 cm); 1.6 cm (1.1-1.9 cm) vs 0.9 cm (0.6-1.3 cm), Z=－4.82, －4.79, －3.74, and －3.09, all P<0.05]. Conclusion:The incidence of UVC tip migration is high, which could be affected by dryness and retraction of the umbilical cord stump and the change in neonatal abdominal circumference and body weight.

Pulmonary arteriovenous malformation and cryptogenic stroke / 国际脑血管病杂志

The relationship between pulmonary arteriovenous malformations (PAVMs) and stroke remains unclear. With the development of imaging technology, studies shows that PAVMs are an important cause of cryptogenic stroke (CS). Most PAVMs are not diagnosed until the onset of stroke. The main pathogenesis of PAVMs-related CS is paradoxical embolism and increased blood viscosity caused by iron deficiency anemia. Antiplatelet therapy and interventional therapy may have a preventive effect on recurrent stroke in such patients. This article summarizes the pathophysiological mechanism, diagnosis and treatment of PAVMs-related CS, hoping to provide new ideas for the diagnosis and treatment of CS.
