BACKGROUND Thoracic endovascular aortic repair (TEVAR) represents a therapeutic concept for type B aortic dissection. Long-term outcomes and morphology after TEVAR for uncomplicated dissection are unknown. METHODS AND RESULTS A total of 140 patients with stable type B aortic dissection previously randomized to optimal medical treatment and TEVAR (n=72)(More)
BACKGROUND Thoracic endovascular aortic repair (TEVAR) represents a novel concept for type B aortic dissection. Although life-saving in acute emergencies, outcomes and survival of TEVAR in stable dissection are unknown. METHODS AND RESULTS One hundred forty patients in stable clinical condition at least 2 weeks after index dissection were randomly(More)
Endovascular aortic repair (EVAR) has emerged as a promising, less invasive alternative to conventional open surgery for the treatment of infrarenal abdominal aortic aneurysms (AAAs). In the last 20 years, the application rate of EVAR and its clinical results have significantly improved thanks to the evolution of stent-grafts and endovascular delivery(More)
OBJECTIVE Endoluminal aortic stent grafting offers a potentially less invasive alternative to open chest surgery, especially in patients with polytrauma. We compare the results of conventional surgical repair and endovascular treatment of traumatic aortic rupture. METHODS Retrospectively, 74 patients with acute traumatic aortic rupture were analyzed. Most(More)
Open thoraco-abdominal aortic aneurysm repair is a demanding procedure with high impact on the patient and the operating team. Results from expert centres show mortality rates between 3-21%, with extensive morbidity including renal failure and paraplegia. Endovascular repair of abdominal aortic aneurysms initially required an undilated portion of the aorta(More)
BACKGROUND Endovascular stent-graft placement is emerging as a novel treatment option for patients with diseases of the descending thoracic aorta. However, currently no consensus guidelines exist to direct uniformity in stent-graft procedures as well as for pre- and postprocedural patient management, unlike that for the management of other cardiovascular(More)
BACKGROUND Safe fixation of endovascular stent grafts in thoracic aortic disease often requires covering of the left subclavian artery (LSA) with the stent graft. It is controversial whether this occlusion can be done without additional risk of ischemic complications. METHODS In 102 patients treated with endovascular stent grafts, the LSA was covered. In(More)
OBJECTIVE Endovascular stent grafting represents a novel concept for type B aortic dissection both in the acute and subacute/chronic setting, with an unknown effect on outcomes. METHODS In a prospective trial 140 patients with stable type B dissection were randomly subjected to elective stent-graft placement in addition to optimal medical therapy (n = 72)(More)
BACKGROUND We evaluated endovascular stent-grafting as a new technique in aortic surgery. METHODS One hundred ninety-six stent-grafts were implanted in the thoracic aorta in 172 patients. All procedures but one were performed in the operating room by a team of cardiothoracic surgeons; 112 operations (57%) were emergency procedures. Twenty-four procedures(More)
BACKGROUND Examination of a large collective combined with individual case analyses may give new insights into mechanisms and prevention of spinal cord ischemia (SCI) after thoracic endovascular repair. METHODS In an 11-year period, stent-grafts were implanted in 406 patients for various aortic pathologic conditions. The mean age was 63 years (15-91(More)
