OBJECTIVE Complete exclusion and depressurization of the aneurysm sac is the prime goal of endovascular repair (EVAR) of abdominal aortic aneurysms. Thus, any EVAR that results in a type I or III endoleak has been classified as a technical failure. The current method to detect endoleaks uses intraoperative aortography. However, aortography is limited by its(More)
BACKGROUND Thoracic aortic aneurysms (TAAs) and type B aortic dissections (ADs) are relatively frequent, serious conditions that are often managed nonoperatively because of perceived poor outcome of standard surgical reconstruction. Recently developed stent graft techniques represent a more attractive, less invasive option. We sought to determine the(More)
Endovascular aneurysm repair (EVAR) of ruptured thoracoabdominal aortic aneurysms may be compromised or even impossible due to short proximal and/or distal necks or landing zones, respectively. Supra-aortic branches may limit the proximal anchorage and visceral or renal arteries the distal anchorage of endografts. While solutions have been proposed to(More)
PURPOSE The purpose of this study was to evaluate the safety and effectiveness of Palmaz stents as a less morbid alternative to traditional surgery for focal aortic arch branch lesions. METHODS Twenty-two patients with symptoms and a mean age of 61.3 years were treated from July 1991 to May 1995 with 26 stents at the following locations: 8 innominate(More)
The endovascular repair of thoracic aortic pathology is on an evolutionary threshold, as advancing technologies and techniques combine to offer the interventionist expanded treatment opportunities. A variety of maneuvers are recommended to address the landing zone limitations to thoracic endografting imposed by the arch vessels: transostial bare stent(More)
OBJECTIVE We sought to define the learning curve relative to the incidence and range of intraoperative problems and to establish guidelines for troubleshooting during the endovascular repair of infrarenal aortic aneurysms. METHODS We prospectively evaluated our first 75 consecutive cases over a 12-month period and focused on perioperative critical events(More)
PURPOSE During endovascular grafting of an abdominal aortic aneurysm (AAA), iliac limb extension to the external iliac artery may be indicated when the common iliac artery is ectatic or aneurysmal. Preliminary or concomitant coil embolization of the internal iliac artery (IIA) is thus necessary to prevent potential reflux and endoleak. We sought to(More)
OBJECTIVES The purpose of this study was (1) to find out whether preoperative inferior mesenteric artery (IMA) patency (on radiographic imaging) predicts IMA-related endoleaks after endovascular repair of infrarenal abdominal aortic aneurysms, (2) to determine feasibility of measuring aneurysm sac pressures in patients with endoleaks, and (3) to report(More)
BACKGROUND The postimplantation syndrome of fever and leukocytosis after endovascular repair of infrarenal aortic aneurysms has not been previously characterized and its etiology is not known. METHODS We studied the first 12 patients who underwent successful endovascular repair of infrarenal aortic aneurysms with Dacron-covered stent-grafts, as part of an(More)
Two hundred fifty years have passed since Frank Nicholls' history-making, accurate observations on the anatomic findings and cause of death of King George II were published. Several decades later, the disease was named, using--for the first time--the terms dissection and dissecting attached to an aortic disease process. Another century went by before(More)
