However, dilatation of the vessels either in the arterial system or in the venous territory is another vessel disease. Varicocele, pelvic, and peripheral varicose veins and hemorrhoids are aneurysms of the venous vascular regions and have been defined as dilating venous disease, recently. Coronary artery ectasia, intracranial aneurysm, and abdominal aortic aneurysm are examples of arterial dilating vascular diseases. Mostly, they have been defined as variants of atherosclerosis. Although there are some similarities in terms of pathogenesis, they are distinct from atherosclerotic disease of the vessels. In addition, pathophysiological and histological similarities and clinical coexistence of these diseases have been demonstrated both in the arterial and in the venous system. This situation underlies the thought that dilatation of the vessels in any vascular territory should be considered as a systemic vessel wall disease rather than being a local disease of any vessel. These patients should be evaluated for other dilating vascular diseases in a systematic manner.","PeriodicalId":14448,"journal":{"name":"International Journal of Vascular Medicine","volume":"2018 ","pages":"9024278"},"PeriodicalIF":2.5,"publicationDate":"2018-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6129317/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36499547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients were divided into four groups in accordance with ultrasound morphologic classification of vessel wall. Duplex scanning of carotid and lower limb arteries was performed. Carotid-femoral (cfPWV) and carotid-radial (crPWV) pulse wave velocity (PWV) were measured. Local carotid stiffness was evaluated by carotid ultrasound.Results: WSR of patients with plaques without and with hemodynamic disturbance was 416±128 s-1 and 405±117 s-1, respectively, which was significantly less than the WSR in patients with intact peripheral arteries - 546±112 s-1. Decreased carotid WSR was associated with increased crPVW, cfPWV, Peterson's elastic modulus, decreased distensibility, and distensibility coefficient.Conclusion: In patients with HTN and atherosclerotic lesions of peripheral arteries, it is registered that the carotid WSR decreased with increasing severity of atherosclerosis.

However, little postprocedural data exists on the outcomes in patients with clinical arterial peripheral vascular pathology [abdominal aortic aneurysm (AAA), carotid artery stenosis (CAS), and peripheral artery disease (PAD)] undergoing TAVR for severe aortic stenosis.Setting: A single center healthcare system.Methodology: A retrospective chart review case-control study of 342 consecutive patients who underwent a TAVR for severe aortic stenosis at Sanford Health in Fargo; ND was performed to determine if preprocedural comorbid AAA, CAS, or PAD was associated with worse outcomes after TAVR.Results: Patients with preprocedural comorbid AAA, CAS, or PAD had no significant difference overall survival at 1 month (94% versus 95% p =.812), 6 months (88% versus 89% p = .847), 1 year (74% versus 83%, p =.130), or 2 years (58% versus 63%, p =.611) after TAVR. Patients with clinical arterial peripheral vascular pathology also had no significant difference in preprocedural outcomes.Conclusion: This study gives evidence to suggest that patients with a comorbid clinical peripheral arterial pathology at the time of TAVR do not have a statistically significant increase in mortality out to 2 years after TAVR and no increase in procedural complications. These results affirm the safety and feasibility of TAVR in patients with AAA, CAS, and/or PAD.","PeriodicalId":14448,"journal":{"name":"International Journal of Vascular Medicine","volume":"2018 ","pages":"2707421"},"PeriodicalIF":1.3,"publicationDate":"2018-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2018/2707421","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36399791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of pharmacological prophylaxis significantly reduces the incidence of thromboembolic events in high risk patients. The aim of this study was to assess appropriateness of DVT prophylaxis in hospitalized medical patients in an Ethiopian referral hospital.Methods: Cross-sectional study design was employed. Patients with a diagnosis of DVT, taking anticoagulant therapy, and those who refused to participate were excluded from the study. Two hundred and six patients were included in the study using simple random sampling method. Modified Padua Risk Assessment Model was used to determine the risk of thromboembolism. SPSS (version 21) was used for analysis.Result: The total risk score for the study subjects ranged from 0 to 11 with a mean score of 3.41 ± 2.55. Nearly half (47.6%) of study participants had high risk to develop thromboembolism. Thrombocytopenia (platelets < 50 billion/L) or coagulopathy, active hemorrhage, and end stage liver disease (INR > 1.5) were the frequently observed absolute contraindications that potentially prevent patients from receiving thromboprophylaxis. Thromboprophylaxis use in nearly one-third (31.6%) of patients admitted in the medical ward of UoGRH was irrational. Patients who had high risk for thromboembolism are more likely to be inappropriately managed for their risk of thromboembolism and patients with thrombocytopenia or coagulopathy were more likely to be managed appropriately.Conclusion: There is underutilization of pharmacologic thromboprophylaxis in medical ward patients.

The patients were followed up for the development of potential clinical presentations for 12 months.Results: MFM implantation was successfully completed in all the patients. During the process, two patients developed endoleak and so they were treated with postdilatation that was performed through balloon intervention, whereby the patients fully recovered. Although a short-term ischemic cerebrovascular event occurred in one of the patients 36 hours after the MFM, the patient recuperated without any noticeable neurological sequelae. Overall, three patients died after the procedure, one of whom died in hospital three days following the intervention due to acute renal failure, while the second one lost his life at the end of the first month due to the occlusion of superior mesenteric and celiac arteries. The third patient died at the end of the third month due to acute myocardial infarction. The rest of the patients developed no complications or had no mortality at their 12-month follow-ups.Conclusion: MFM can be preferred as an alternative approach in the treatment of aorta and iliac artery aneurysms including major lateral branches.

In this review, we will evaluate the role of percutaneous transluminal angioplasty (PTA) according to patency of arteriovenous fistula and grafts.

The infection rate is as low as the number of complications. Fistula can be used in dialysis in the same day without the need for a central venous catheter. Primary patency is >50% in the first year while primary assisted patency is 80-90% in the same time period. Repeated PTA is as durable as the primary PTA. An early PTA carries a risk of new interventions. Cutting balloon can be used as a second-line method. Stents and covered stents are kept for the management of complications and central outflow venous stenosis. PTA is the treatment of choice for stenosis or obstruction of dialysis fistulas. Repeated PTA may be needed for better patency. Drug eluting balloon may become the future in PTA of dialysis fistula, but more trials are needed.","PeriodicalId":14448,"journal":{"name":"International Journal of Vascular Medicine","volume":"2018 ","pages":"1420136"},"PeriodicalIF":1.3,"publicationDate":"2018-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2018/1420136","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36118038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the multicenter randomized MIMICS trial, treatment of femoropopliteal disease with the BioMimics 3D (n = 50) significantly improved 2-year primary patency (log-rank test p = 0.05) versus a control straight stent (n = 26), with no cases of clinically driven target lesion revascularization between 12 and 24 months (log-rank test p = 0.03 versus controls). In geometric X-ray analysis, the BioMimics stent was significantly more effective in imparting a helical shape even when the arterial segment was moderately to severely calcified. Computational fluid dynamics analysis showed that average wall shear was significantly higher with the helical centerline stent (1.13 ± 0.13 Pa versus 1.06 ± 0.12 Pa, p = 0.05).
