OBJECTIVE The purpose of this study was to determine the effects of patient, surgeon, and hospital factors on survival after repair of ruptured abdominal aortic aneurysm (AAA) and to compare them with risk factors for survival after elective AAA repair. It was hypothesized that patients operated on by high-volume surgeons with subspecialty training would(More)
OBJECTIVE The purpose of this study was to determine factors associated with increased likelihood of patients undergoing surgery to repair ruptured abdominal aortic aneurysms (AAAs). Specifically, we investigated whether men were more likely than women to be selected for surgery after rupture of AAAs. METHODS All patients with a ruptured AAA who came to a(More)
OBJECTIVE Records for all patients in Ontario who underwent elective repair of abdominal aortic aneurysms (AAAs) or repair of ruptured AAAs between 1993 and 1999 were studied to determine whether the profile of surgeons or patients changed and to determine whether postoperative mortality changed over time. The secondary objective was to describe long-term(More)
BACKGROUND It has been proposed by Zamboni and colleagues that multiple sclerosis is caused by chronic cerebrospinal venous insufficiency, a term used to describe ultrasound-detectable abnormalities in the anatomy and flow of intra- and extracerebral veins. We conducted a meta-analysis of studies that reported the frequency of chronic cerebrospinal venous(More)
OBJECTIVE Blunt abdominal aortic injury (BAAI) is very rare, and current literature is limited to case series of single-center experience. Through an analysis of the National Trauma Data Bank, the largest aggregation of United States trauma registry data, our aim was to characterize the associated injury pattern, contemporary management, and in-hospital(More)
PURPOSE To test and validate magnetic resonance imaging (MRI) sequences for peripheral artery lesion characterization and relate the MRI characteristics to the amount of force required for a guidewire to puncture peripheral chronic total occlusions (CTOs) as a surrogate for immediate failure of endovascular therapy. METHODS Diseased superficial femoral,(More)
BACKGROUND Managing postoperative electrolyte imbalances often is driven by dogma. To identify areas of improvement, we assessed the practice pattern of postoperative electrolyte management among surgeons and residents. STUDY DESIGN An online survey was distributed among attending surgeons and surgical residents at the University of Toronto. The survey(More)
OBJECTIVES Smartphones have become the most important personal technological device. M-learning is learning through mobile device educational technology. We aim to assess the acceptability of a smartphone learning experience among the vascular trainees and determine if results could inform formal teaching efforts. METHODS A survey of the vascular trainees(More)
BACKGROUND Venous leg ulcers (VLUs) are common but challenging health problems. Better understanding of the risk factors involved in delayed healing of VLUs may therefore guide individualized treatment plans to improve patient outcomes. OBJECTIVE We sought to identify the risk factors associated with delayed healing of VLUs in patients seen at a tertiary(More)
Executive Summary Background: Zamboni has proposed that multiple sclerosis (MS) is caused by abnormalities in the anatomy and flow of the cerebral veins, which he has called chronic cerebrospinal venous insufficiency (CCSVI). The primary purpose of this systematic review was to examine the evidence evaluating the association between venous abnormalities and(More)
