Patients can be treated effectively for AVF nonmaturation early on, and it is possible to identify those patients at risk of nonmaturation most effectively with an early postoperative assessment of hemodynamic risk factors. Additional research is needed that concentrates on adopting the strategy of early treatment of patients with postoperative risk factors.
IntroductionUse of patch angioplasty in carotid endarterectomy (CEA) is suggested to reduce the risk of restenosis and recurrent ipsilateral stroke. The objective is to conduct a systematic review with meta-analysis and trial sequential analysis as well as Grading of Recommendations Assessment, Development and Evaluation (GRADE) assessments comparing the benefits and harms of CEA with primary closure of the arterial wall versus CEA with patch angioplasty in patients with a symptomatic and significant carotid stenosis.Methods and analysisThe review shall be conducted according to this published protocol following the recommendations of the ‘Cochrane’ and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Randomised clinical trials comparing CEA with primary closure of the arterial wall versus CEA with patch angioplasty (regardless of used patch materials) in human adults with a symptomatic and significant carotid stenosis will be included. Primary outcomes are all-cause mortality at maximal follow-up, health-related quality of life and serious adverse events. Secondary outcomes are symptomatic or asymptomatic arterial occlusion or restenosis, and non-serious adverse events. We will primarily base our conclusions on meta-analyses of trials with overall low risk of bias. However, if pooled point estimates of all trials are similar to pooled point estimates of trials with overall low risk of bias and there is lack of a statistical significant interaction between estimates from trials with overall high risk of bias and trials with overall low risk of bias we will consider the precision achieved in all trials as the result of our meta-analyses.Ethics and disseminationThe proposed systematic review will collect and analyse secondary data from published studies therefor ethical approval is not required. The results of the systematic review will be disseminated by publication in a peer-review journal and submitted for presentation at relevant conferences.PROSPERO registration numberCRD42014013416.
The fenestrated Anaconda is a viable treatment option for complex abdominal aortic aneurysms. Acceptable mortality and morbidity and low reintervention rates contribute to good midterm results. Occurrence of early type I endoleak was relatively common, but these resolved spontaneously in all patients.
Several successful cases of endovascular treatment of type B dissections in patients with Marfan syndrome have been reported. In our patient with Marfan syndrome, a type B dissection was successfully treated endovascularly. Three weeks after this procedure, a computed tomographic angiography (CTA) revealed a perforation of the aortic wall distal to the left subclavian artery by a bare strut of the stent graft. A second stent graft was placed to treat this complication. In patients with Marfan syndrome, complications might be prevented by using stent grafts specifically developed to treat dissections. However, specific complications, eg, perforation, must be taken into account and patients have to be followed attentively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
