Background: Endovascular repair of aortic diseases is a well-established therapeutic alternative for patients with the appropriate anatomy and/or high surgical risk, as it provides lower morbidity and mortality rates. This study aimed to analyse the outcomes of asymptomatic patients undergoing endovascular treatment of thoracic aortic dissections with an aortic diameter > 5.5 cm or endoleaks. Technical success, therapeutic success, morbidity, mortality, and perioperative complication and reintervention rates were assessed. Methods: The present retrospective study, which was performed at a reference centre from January, 2010 to July, 2011, analysed consecutive patients undergoing endovascular repair of chronic complicated type B aortic dissections based on the Stanford classification. Results: Twenty-six patients were treated. The mean age was 56.4 ± 7 years, and 61.5% were males. Technical and therapeutic success rates were 100% and 74%, respectively. The perioperative mortality was 7.6%, and the mortality rate in the first year of follow-up was 19.3%. The reintervention rate was 15.3%. Conclusions: In the present study, endovascular treatment of chronic type B aortic dissections proved to be a feasible method associated with acceptable perioperative complication rates. The therapeutic success and reintervention rates indicated the
Background:The endovascular treatment of carotid atherosclerotic disease has continuously evolved, although ischemic or embolic complications may occur even with the use of cerebral protection systems. This study was aimed at evaluating the perioperative results of an initial series of patients using the flow reversal system during carotid angioplasty. Methods: This was a prospective, non-randomized, non-controlled, singlecenter study. Asymptomatic patients with lesions > 70% or symptomatic patients with lesions > 50% in the internal carotid artery were included. The flow reversal system was used with pre-dilation in selected cases and open-cell stents were used in all cases. We evaluated the occurrence of major and minor strokes, transient ischemic attacks (TIAs), acute myocardial infarction (AMI) and death within 30 days after the procedure. Results: Between September 2010 and February 2011 carotid angioplasty was performed in 17 patients, most of them male (70.6%), with mean age of 66.7 + 8 years, of which 17.6% were diabetic. Approximately half of the patients were symptomatic, 5 patients had a prior history of stroke (29.4%) and 3 had TIA (17.7%). Technical success was achieved in 100% of the patients. There was one death (5.9%), 24 hours after the procedure in a high surgical risk patient treated in the evolution phase of an AMI due to repetitive TIAs. There were no cases of major or minor strokes or TIAs during the follow-up. Conclusions: In our study, the flow reversal system proved to be effective and safe in patients undergoing carotid angioplasty.
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.
