True brachial artery aneurysm is relatively rare. There are only some cases that have been reported previously in medical literature. Brachial artery aneurysm might be asymptomatic or revealed by a brachial mass with beating pulse or peripheral ischemia. The diagnosis usually relies on ultrasound and arterial scan or magnetic resonance imaging (MRI). The main treatment is the surgery which allows cutting the aneurysm and grafted with a part of great saphenous vein by two end-to-end anastomoses. We present a case report of true aneurysm of brachial artery in a 40 years old woman who was treated in Thai Binh Medical University Hospital.","PeriodicalId":17397,"journal":{"name":"Journal of Vascular Medicine & Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88050217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, RT-PCR is considered the gold standard. However, its diagnostic priority compared to Chest CT remains unknown. Objective: We sought to perform a meta-analysis using retrospective studies comparing Chest CT and RT-PCR in COVID-19 detection among hospitalized patients. Methods: We performed a comprehensive literature search using Pubmed and Google Scholar for studies comparing Chest CT and RT-PCR between January 1 and April 3, 2020. Outcomes included COVID-19 detection using RT-PCR alone, Chest CT alone, true positives when combining the two, and true negatives when combining the two. Results were reported as an odds ratio (OR) with 95% CI. Results: A total of 6 retrospective studies were included comparing RT-PCR with Chest CT. A total of 1,400 patients were enrolled (average age 46.28 ± 2.7 years, 41.6% were males). Chest CT was superior to RT-PCR for COVID-19 detection [OR 3.86, 95% CI (1.79- 8.31, p=0.0006)]. Heterogeneity (I2) was high (75%), but sensitivity analysis failed to reveal any single contributor to observed heterogeneity. Conclusion: Chest CT appears to be a more sensitive and quicker alternative to RT-PCR in the detection of COVID-19 in hospitalized patients, and may serve as a superior screening tool.","PeriodicalId":17397,"journal":{"name":"Journal of Vascular Medicine & Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89917328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

García","doi":"10.35248/2329-6925.20.8.389","DOIUrl":"https://doi.org/10.35248/2329-6925.20.8.389","url":null,"abstract":"Infrainguinal revascularization in end-stage renal disease patients is controversial, despite of patency and limb salvage rates observed in several studies. This study provides more favourable overall survival and amputation free-survival rates than the contemporary study of the same characteristics. The revascularization of patients with ESRD is frequently conditioned by poor survival. With the data we provide, approximately half of the patients were alived and their limb was salvaged at 3 years, and this is encouraging. Thus, we can be more aggressive in daily practice and offer revascularization in ESRD patients. Objective: This study analyzed long-term outcomes and evaluate the benefits and limits of infrainguinal revascularization (IR) both surgical and endovascular revascularization with critical limb ischemia (CLI) in patients with and without ESRD. Material and Methods: A total of 1188 patients were prospectively collected and analyzed retrospectively. We included 108 (9.1%) patients with ESRD and of them 70 (64.8%) receiving hemodialysis. Results: The 30-day mortality rate was higher in ESRD group (5.6 vs. 1.8, p=0,009). The second patency was similar in both groups at 1 and 3 years (87.6% and 85.3% vs. 82.9% and 81.6%). ESRD patients had a lower overall survival and amputation free-survival (AFS) (at 1 year 79.6% vs. 91.8% and at 3 years 57.9% vs. 79.1%, p<0.001) and (at 1 year 68.2% vs. 78.8% and at 3 years 45.7% vs. 64.6%, p<0,001) than non- ESRD patients. The limb salvage rates achieved excellent outcomes during follow-up at 1 and 3 years. (83.5% and 83.2% vs. 66.0% and 77.6% (p=0.194). Cox regression analysis showed that hemodialysis was an independent predictor of all-cause mortality and AFS (HR=2.38, 95% CI 1.54- 3.68, p<0,001). Octogenarian patients and coronary disease was independent predictor of all-cause mortality (HR=3.05, 95% CI 2.3-4.01, p<0.001) and (HR=1.49, 95% CI 1.14-1.95, p=0.03). Conclusions: The long-term patency and limb salvage rates in patients who underwent IR with CLI and ESRD was comparable with non- ESRD patients. Despite, the overall survival and amputation free-survival rates was poorer in ESRD patients, we advocated for aggressive revascularization attitude in ESRD patients but we must individualize treatment decision and should be offered revascularization for patients with acceptable life expectancy.","PeriodicalId":17397,"journal":{"name":"Journal of Vascular Medicine & Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75242104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is closely related to ineffective contact between the endograft ends and the wall of the blood vessel. In this study, we have developed a realistic stent-graft deployment simulation using the Finite Element Method of 3D nitinol stent in a patient-specific Thoracic Aortic Aneurysm (TAA). This work aims to investigate the impact of the realistic complete stenting procedure by a progressive expanding deployment of the stent graft on the migration behaviour. A comparison of results is investigated between the realistic and non-realistic deployment methods to predict the overall (stent–aorta) biomechanical behaviour. We have also investigated the effect of including the graft material on the mechanical behaviour of the (stent-graft) during the deployment and the contact stability (stentgraft)/aorta after the deployment. The simulation results show that the realistic deployment method did indeed influence the mechanical behaviour, positioning, and eventually the functioning of the stent-graft when compared with the traditional deployment methods. The impact of adding the fabric tissue to the stent being deployed in an idealized straight centerline on the contact stiffness seems to be modest compared the deployed stent without graft.","PeriodicalId":17397,"journal":{"name":"Journal of Vascular Medicine & Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90357551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Until recently 1-2 sec hit inflation pumps were used generating emptying veins and arterial-venous pressure gradient enabling greater arterial flow. To obtain better perfusion results we used a pump that, in contradiction to the “empty veins” devices, obstructed limb venous outflow by venous occlusions and in a long period therapy expanded perfusion vessels and brought about persistent reactive hyperemia. Aim: To check toe and calf arterial inflow measured by venous stasis plethysmography and capillary flow velocity during arterial assist IPC in a long-term therapy of ischemic legs. Material and methods: Eighteen patients (12M, 6F) age 62 to 75 with leg peripheral arterial disease (PAD, Fontaine II) were studied. Pneumatic device with two 10 cm wide cuffs (foot, calf) (Bio Compression Systems, Moonachie, NJ, USA) inflated to 120 mmHg for 5-6 sec to occlude the venous flow, deflation time 16 sec, applied for 45-60 min daily for a period of 2 years. Results: Increase in toe arterial pressure, volume, capillary blood flow velocity and one-minute arterial inflow test was observed. The two years therapy showed persistence of resting limb increased toe capillary flow. Intermittent claudication distance increased by 20-120%. After two years assist TBI increased from 0.2 to 0.6 (range 0.3 to 0.8) (p<0.05 vs pre-therapy). Conclusions: The crucial factor of rhythmic repeated venous outflow obstructions should be taken into account in designing effective assist devices.","PeriodicalId":17397,"journal":{"name":"Journal of Vascular Medicine & Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79868690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design: Randomized, cross-over, blinded trial of an intermittent mechanical compression device (Venowave), compared with a sham compression device. Setting: Hamilton Health Sciences, Hamilton, Canada. Participants: 27 patients with severe peripheral limb ischemia, as identified by at least one of: i) ABI<0.4; ii) ACD<200 m (Fontaine stage IIb); iii) toe-brachial index<0.5; or iv) toe pressure<40 mmHg or rest pain due to arterial ischemia. Main Outcome Measures: The primary outcome measure was Absolute Claudication Distance (ACD) while walking on a treadmill. Secondary outcome measures included Initial Claudication Distance (ICD), walk time measured in minutes, and a modified version of the Walking Impairment Questionnaire (WIQ). Results: There was no significant difference in ACD (mean difference: 14.1 m; 95% CI: -31.6 m-59.9 m; p=0.53) or ICD (mean difference: 5.9 m; 95% CI: -26.3 m-14.5 m; p=0.55) between active and sham devices. Mean walk time was identical between active and sham devices (5.6 minutes (2.1) vs. 5.6 minutes (2.0); p=0.99).
