BACKGROUND: Acute aortic dissection is known as the most dangerous aortic disease, with management and prognosis determined as the disruption of the medial layer provoked by intramural bleeding. The objective of this study was to evaluate the safety and necessity of antiplatelet therapy on patients with Stanford Type B aortic dissection (TBAD) who underwent endovascular aortic repair (EVAR). METHODS: The present study retrospectively analyzed 388 patients with TBAD who underwent EVAR and coronary angiography...

PURPOSE: To compare the follow-up results of endovascular aneurysm repair (EVAR) vs open surgery (OS) for inflammatory abdominal aortic aneurysms (IAAAs) with regard to immunoglobulin G4-related diseases (IgG4-RD), which are fibrous inflammatory conditions characterized by elevated serum IgG4 concentrations and numerous infiltrations of IgG4(+) plasmacytes. METHODS: Between January 2005 and December 2015, 91 patients were treated with EVAR (begun in 2008) and 166 patients underwent OS for AAA...

BACKGROUND: During the past decade, endovascular treatment has become the treatment of choice for all types of aortoiliac occlusive disease, including TASC C and D lesions. Patency rates, however, are still below those of open surgical techniques. One propagated technique to improve patency rates is the use of covered stents. This review assessed the available literature on covered stents for aortoiliac occlusive disease. METHODS: An extensive search was performed of the MEDLINE, Embase, and Cochrane databases...

BACKGROUND: Spinal cord injury (SCI) is reported to occur in 3-12% of thoracic endovascular aortic repair (TEVAR) cases, but is a potentially preventable complication of TEVAR for thoracoabdominal pathologies. Although many strategies have been devised to reduce the incidence of SCI, the effectiveness of prophylactic cerebrospinal fluid drainage (CSFD) and left subclavian artery (LSA) revascularization remains controversial. METHODS: From 2012 to 2014, 162 patients underwent TEVAR at a single institution...

BACKGROUND: The most feared complications following endoscopic endonasal skull base surgery are arterial vascular injuries. Previously published literature is restricted to internal carotid artery injuries. The ideal method for controlling arterial bleeding during this kind of procedure is debated, and a variety of techniques have been advocated. OBJECTIVE: To evaluate the management and outcome following intraoperative arterial injury during endoscopic endonasal skull base surgery...

REVIEW
Norman R Hertzer
Ruptured abdominal aortic aneurysms have an alarmingly high mortality rate that often exceeds 50%, even when patients survive long enough to be transported to hospitals. Historical data have shown that ruptures are especially likely to occur with aneurysms measuring ≥6 cm in diameter, but there are so many exceptions to this that several randomized clinical trials have been done in an attempt to determine whether smaller aneurysms should be repaired electively as soon as they are discovered. More recently, further trials have been conducted in order to compare the relative benefits and disadvantages of modern endovascular aneurysm repair to those of traditional open surgery...

The success of endovascular repair of abdominal aortic aneurysms remains limited due to the development of endoleaks. Sac embolization has been proposed to manage endoleaks, but current embolizing materials are associated with frequent recurrence. An injectable agent that combines vascular occlusion and sclerosing properties has demonstrated promise for the treatment of endoleaks. Moreover, the inhibition of aneurysmal wall degradation via matrix metalloproteinases (MMPs) may further prevent aneurysm progression...

Feature selection is essential in medical area; however, its process becomes complicated with the presence of censoring which is the unique character of survival analysis. Most survival feature selection methods are based on Cox's proportional hazard model, though machine learning classifiers are preferred. They are less employed in survival analysis due to censoring which prevents them from directly being used to survival data. Among the few work that employed machine learning classifiers, partial logistic artificial neural network with auto-relevance determination is a well-known method that deals with censoring and perform feature selection for survival data...

BACKGROUND: Abdominal aortic aneurysms pose a substantial clinical burden, and a significant proportion are not anatomically suitable for open repair or standard endovascular aneurysm repair (EVAR), instead requiring fenestrated EVAR (fEVAR). We sought to compare clinical outcomes and trends over time in patients undergoing fEVAR in Australia. METHODS: We conducted a retrospective analysis of all patients undergoing fEVAR at a tertiary referral centre between 2010 and 2015, including outcomes and complications, both as inpatients and after discharge...

OBJECTIVE: Spinal cord ischemia (SCI) is a devastating complication of thoracic aortic aneurysm repair in the era of thoracic endovascular aneurysm repair (TEVAR). This review aims to clarify the causes of SCI during TEVAR and to propose ways that it may be prevented. METHODS AND RESULTS: We performed an extensive literature search of SCI during TEVAR. Based on the existing literature, we examined the anatomy of the anterior spinal cord artery, which supplies blood to the anterior aspect of the spinal cord, and discuss reported effective ways to prevent SCI during TEVAR, including augmentation of arterial blood pressure and drainage of cerebrospinal fluid...

Endovascular aortic repair (EVAR) is often followed by aneurysm recurrence. Alginate oligosaccharide (AOS) has potential antitumor properties as a natural product while the related mechanisms remain unclear. Toll-like receptor (TLR) signaling is associated with inflammatory activity of aneurysm and may be affected by miR-29b. Thus, inhibitory function of AOS on aneurysms was explored by measuring the important molecules in TLR4 signaling. After EVAR, a total of 248 aortic aneurysm patients were recruited and randomly assigned into two groups: AOS group (AG, oral administration 10-mg AOS daily) and control group (CG, placebo daily)...

OBJECTIVE: Ischemic colitis (IC) is a well-described complication of ruptured abdominal aortic aneurysms (rAAA). The purpose of this study was to compare the incidence of IC in patients with rAAA undergoing open (OR) vs. endovascular aneurysm repair (EVAR) at a single institution. In addition, we analyzed the incidence of ischemic colitis pre- and post- implementation of a formal rupture AAA protocol (rEVAR protocol). METHODS: A retrospective analysis of prospectively collected data on all patients presenting with rAAA to our institution between Jan 2002 and Oct 2013 was performed...

OBJECTIVE/BACKGROUND: The aim is to present current results of open complex aortic repair in patients with connective tissue disease (CTD). METHODS: This was a retrospective cross-border, single centre study. From February 2000 to April 2016 72 aortic operations were performed on 65 patients with CTD (41 male, median age 41 years [range 19-70 years]). Fifty-six patients (86%) underwent at least one previous aortic repair (71 open, four endovascular), including 33 patients (51%) operated before at the site of the procedure reported here...

PURPOSE: To identify anatomic and hemodynamic changes associated with impending visceral chimney stent-graft occlusion after endovascular aneurysm repair (EVAR) with the chimney technique (chEVAR). METHODS: A retrospective evaluation was performed of computed tomography scans from 41 patients who underwent juxtarenal chEVAR from 2008 to 2012 to identify stent-grafts demonstrating conformational changes following initial placement. Six subjects (mean age 74 years; 3 men) were selected for detailed reconstruction and computational hemodynamic analysis; 4 had at least 1 occluded chimney stent-graft...
