PURPOSE The United Kingdom Small Aneurysm study has demonstrated the low risk of rupture in aneurysms less than 5.5 cm in diameter. With the advent of endoluminal techniques, patients considered unfit to undergo laparotomy are now considered for endovascular repair. However, the natural history of aneurysms larger than 5.5 cm remains uncertain, especially(More)
OBJECTIVE To measure and compare the physiologic, metabolic, and hemodynamic responses to aortofemoral bypass grafting by three techniques: open or conventional laparotomy, laparoscopic-assisted (minilaparotomy), and totally laparoscopic grafting. METHODS Twenty-four laboratory-bred hounds were randomized to one of three groups (open,(More)
Dysphagia and recurrent gastroesophageal reflux complicate use of the Angelchik prosthesis. The authors developed an inflatable silicone device, similar to the Angelchik prosthesis, that may allow for the adjustment of the total pressure exerted around the gastroesophageal junction after implantation. To estimate its potential to prevent gastroesophageal(More)
Our aim was to examine the feasibility of a totally laparoscopic insertion of a bifurcated aortofemoral bypass graft in a canine model and to compare the surgical results with those in control animals undergoing standard grafting and laparoscopic-assisted bypass procedures. Using a six-port approach, we exposed and cross clamped the aorta, tunneled a(More)
There is limited data regarding hyperbaric oxygen's effectiveness in the treatment of nonhealing arterial insufficiency ulcers. This study was designed to analyze healing rates and amputation rates in patients who underwent adjunctive hyperbaric oxygen for a nonhealing arterial insufficiency ulcer. A retrospective chart review was completed on patients who(More)
INTRODUCTION Hyperbaric oxygen (HBO2) therapy uses different maximum treatment pressures. A side effect of HBO2 is oxygen toxicity seizure. The purpose of this study was to determine the overall incidence of oxygen toxicity seizure and assess risk at different treatment pressures. METHOD A retrospective chart review was performed on patients who underwent(More)
BACKGROUND Limited population-based data are available on trends in the incidence of arterial surgery, balloon angioplasty, and amputation for arterial occlusive disease of the legs over the past two decades. METHODS We identified all elective and emergency arterial operations, balloon angioplasty procedures, and amputations performed for all residents of(More)
