Resuscitative endovascular balloon occlusion of the aorta (REBOA) was developed for controlling intra-abdominal arterial bleeding before definitive bleeding control, and is commonly used in patients with ruptured abdominal aortic aneurysms. Although there is limited evidence for other uses of REBOA, we used REBOA in a patient with massive gastrointestinal bleeding. A 53-year-old man with hematochezia was admitted to our emergency department with an initial systolic blood pressure (SBP) of 83 mmHg. His SBP decreased to 40 mmHg in 10 minutes despite rapid fluid infusion...

Ruptured abdominal aortic aneurysm (rAAA) is an emergent condition that carries higher mortality rate. Although there had been development of interventional and surgical technique besides improved critical care, mortality rates were still varied between 35 and 53% in the reported series. Preoperative shock was reported as a major factor predicting mortality rate. Feasibility of simultaneous endovascular repair of rAAA and silent thoracic aortic aneurysm (TAA) is not known. Herein, we aimed to demonstrate the advantage of simultaneous endovascular repair of rAAA and silent TAA in the settling of hemodynamic and neurologic instability...

An Abdominal Aortic Aneurysm (AAA) is a permanent focal dilatation of the abdominal aorta at least 1.5 times its normal diameter. The criterion of maximum diameter is still used in clinical practice, although numerical studies have demonstrated the importance of other biomechanical factors. Numerical studies, however, must be validated experimentally before they can be clinically implemented. We have developed a methodology for manufacturing anisotropic AAA replicas with non-uniform wall thickness. Different composites were fabricated and tested, and one was selected in order to manufacture a phantom with the same properties...

BACKGROUND: In 2014, we published a series of articles in the Journal of Vascular Surgery that detailed the decrease in volume of open aneurysm repair (OAR) completed for abdominal aortic aneurysm (AAA) by vascular surgery trainees. At that time, only data points from 2000 through 2011 were available, and reliable predictions could only be made through 2015. Lack of data on endovascular aneurysm repair (EVAR) using fenestrated (FEVAR) and branched (BrEVAR) endografts also affected our findings...

BACKGROUND: Short-term survival benefits of endovascular aneurysm repair (EVAR) versus open repair of intact abdominal aortic aneurysms have been shown in randomised trials, but this early survival benefit is lost after a few years. We investigated whether EVAR had a long-term survival benefit compared with open repair. METHODS: We used data from the EVAR randomised controlled trial (EVAR trial 1), which enrolled 1252 patients from 37 centres in the UK between Sept 1, 1999, and Aug 31, 2004...

We herein report a case of a rare complication of spinal cord ischemia (SCI) following endovascular aneurysm repair (EVAR). Computed tomography showed stenosis and calcification of bilateral iliac arteries and a saccular aneurysm of the terminal aorta. Paraplegia occurred soon after balloon angioplasty of iliac arteries and EVAR. Cerebrospinal fluid drainage was not performed because the patient was on dual antiplatelet drugs. The patient was treated with intravenous methylpredonisolone and naloxone; however, this did not improve his paraplegia...

A 79-year-old man underwent endovascular repair for abdominal aortic aneurysm (AAA), and both internal iliac arteries (IIAs) were preserved. Postoperatively, loss of appetite developed. On the fifth day, computerized tomography (CT) showed inferior mesenteric artery thrombus formation, necrosis of the descending colon and rectum, and generalized peritonitis. The endovascular devices had not migrated. A colonic resection was performed. Histological analysis confirmed intestinal necrosis associated with mesenteric thrombus...

In the modern endovascular era, abdominal aortic aneurysm repair is still not free of complications with re-interventions following endovascular aneurysm repair (EVAR) being more common than with open surgical repair. A variety of endovascular, open surgical and combined techniques were described according to the anatomical considerations and general health of the patient to achieve the best possible result after these complications. In cases of type Ib endoleak following aorto-uni-lateral EVAR for an abdominal aortic aneurysm, the use of the internal branched device (IBD) constitutes a safe and effective technique...

Objectives: Unexpected systemic inflammatory response with high fever and increase in C-reactive protein (CRP) occurred frequently after endovascular abdominal aortic aneurysm repair (EVAR). This excessive inflammatory response affects the postoperative course. We evaluated the effects of steroid on the postoperative inflammatory response after EVAR. Methods: Steroid therapy, intravenous infusion of methylprednisolone 1000 mg just after the anesthesia induction, was started since December 2012. After induction of the steroid therapy, 25 patients underwent EVAR with steroid therapy (Group S)...

Introduction: Abdominal aortic aneurysm has a lower incidence in the female population, but a higher complication rate. It was been hypothesized that some anatomical differences of abdominal aortic aneurysm in women could be responsible for that. We proposed to analyze our data to understand the differences in the clinical and anatomical characteristics and the outcomes of patients undergoing endovascular aneurysm repair, according to gender. Methods: A retrospective analysis of patients undergoing endovascular aneurysm repair between 2001-2013 was performed...

AIM: A ruptured abdominal aortic aneurysm (rAAA) remains a significant threat to life, with a 30-50% in-hospital mortality rate. The recent introduction of emergency endovascular aneurysm repair (rEVAR) in New Zealand presents an alternative to open repair for rAAAs. The aim of this paper is to review the current experience in New Zealand in the repair of rAAAs. METHODS: Data from the Australasian Vascular Audit (AVA) was reviewed, with data pertaining to rAAAs collected for the five-year period from January 2010 to December 2014...

Since the introduction of fenestrated endovascular aneurysm repair (FEVAR) in 1996, great advances have been made in endograft development. Custom-made and off-the-shelf fenestrated and branched endografts have been used to treat patients with complex abdominal aortic and thoraco-abdominal aneurysms. Most experience has been gained with the Cook Zenith® fenestrated endograft (Cook Medical Inc., Limerick, Ireland). The Cook Zenith® endograft is customized with fenestrations, (fixed) inner or outer branches, or a combination of them, to cover a wide range of complex aneurysms...

Endovascular aneurysm repair (EVAR) is a safe alternative to open surgical repair for an abdominal aortic aneurysm. However, unfavorable aortic anatomy of the aneurysm has restricted the widespread use of EVAR. Anatomic limitation is most often related to characteristics of the proximal neck anatomy. In this report, we described a patient with a severely angulated proximal neck who underwent EVAR, but required repeat intervention because of thrombotic occlusion of stent graft limbs.

OBJECTIVE: Despite vast improvement in the field of vascular surgery, elective abdominal aortic aneurysm (AAA) repair still leads to perioperative death. Patients with asymptomatic AAAs, therefore, would benefit from an individual risk assessment to help with decisions regarding operative intervention. The purpose of this study was to describe such a 30-day postoperative (POD) risk prediction model using American College of Surgeons National Surgical Quality Improvement Project (NSQIP) data...

OBJECTIVE: Abdominal aortic aneurysm (AAA) is a frequent, potentially life-threatening, disease that can only be treated by surgical means such as open surgery or endovascular repair. No alternative treatment is currently available, and despite expanding knowledge about the pathomechanism, clinical trials on medical aneurysm abrogation have led to inconclusive results. The heterogeneity of human AAA based on histologic examination is thereby generally neglected. In this study we aimed to further elucidate the role of these differences in aneurysm disease...
