OBJECTIVES This study tested the hypotheses that endografts can be visualized and navigated in vivo solely under real-time magnetic resonance imaging (rtMRI) guidance to repair experimental abdominal aortic aneurysms (AAA) in swine, and that MRI can provide immediate assessment of endograft apposition and aneurysm exclusion. BACKGROUND Endovascular repair for AAA is limited by endoleak caused...

OBJECTIVES The purpose of this retrospective, single-institution study is to describe a 4-year experience of examining early and late clinical outcomes after endovascular repair of abdominal aortic aneurysm (AAA). MATERIALS AND METHODS Between October 1998 and January 2003, 455 patients were submitted for AAA treatment, of whom 269 underwent open repair and 186 were treated with an endovascul...

Background—Thoracic endovascular aortic repair offers a less invasive approach for the treatment of ruptured descending thoracic aortic aneurysms (rDTAA). Due to the low incidence of this life-threatening condition, little is known about the outcomes of endovascular repair of rDTAA and the factors that affect these outcomes. Methods and Results—We retrospectively investigated the outcomes of 87...

OBJECTIVE Endovascular techniques to treat abdominal aortic aneurysms results in lower morbidity and mortality rates. However, dilation of the common iliac arteries prevents adequate distal sealing, which compromises the procedure success. The aim of this study is report the long-term outcomes of patients with abdominal aortic aneurysms associated with aneurysm of the common iliac artery follow...

INTRODUCTION The management of thoracic aortic disease involving the ascending aorta, aortic arch and descending thoracic aorta are technically challenging and is an area in constant development and innovation. OBJECTIVE To analyze early and midterm results of hybrid treatment of arch aortic disease. METHODS Retrospective study of procedures performed from January 2010 to December 2012. The...

A ruptured thoracic aorta is a rare but lifethreatening condition requiring immediate intervention. Possible causes of a ruptured thoracic aorta are ruptured descending thoracic aneurysms, acute type B aortic dissections, penetrating aortic ulcers, and traumatic thoracic aortic injuries (TTAI). Thoracic endovascular aortic repair (TEVAR) offers an effective treatment for these acute thoracic ao...

OBJECTIVE To measure the pulsatility of human aneurysms before and after complete exclusion with an endograft. METHOD Five aortic aneurysms obtained during necropsy were submitted to pulsatile perfusion before and after implantation of a bifurcated endograft. The specimens were contained in a closed chamber filled with saline solution. A vertical tube attached to the chamber was used to measu...

BACKGROUND Supraaortic branches limit extended application of endovascular aortic repair. For this purpose, we applied extensive reconstructions. METHODS Between October 2002 and March 2005, 11 patients (mean age 72.3 years) presented with acute or chronic aortic diseases originating from the aortic arch (arch aneurysms n=8, type B dissections n=3). Treatment was by autologous sequential tran...

The modality of treatment and the appropriate time point to treat type II endoleaks after endovascular repair of abdominal aortic aneurysms (EVAR) remain controversial issues. The purpose of the present study was to assess the efficacy of translumbar embolization of type II endoleaks after endovascular repair of aortic aneurysm repair. Eighty-four consecutive patients after EVAR were analyzed f...

PURPOSE To evaluate the acute and midterm effectiveness of a novel vascular occlusion device for embolization of the internal iliac artery (IIA) before endovascular repair of aortoiliac aneurysms. MATERIALS AND METHODS Between March 2005 and April 2006, nine men (mean age, 75 years +/- 5; range, 66-83 y) with aortoiliac aneurysms underwent bifurcated endovascular stent-graft procedures. All t...
