rome and Aortic-Diseases

To report our single-center experience with the chimney technique for aortic arch pathologies and the mid- to long-term results in these patients.. From June 2002 to May 2013, 26 patients (18 men; mean age 71.2 years, 53-86) underwent thoracic endovascular aortic repair (TEVAR) combined with chimney technique. Indications for treatment were: a proximal landing zone <15 mm long distal to the left subclavian artery (LSA), thoracic aortic aneurysm (n=13), complicated type B aortic dissection (n=10), type I endoleak after previous TEVAR (n=2), and penetrating aortic ulcer (n=1). Treatment was performed in the emergency setting in 7 cases. The 28 chimney stent-grafts (double chimneys in 2 patients) were deployed in the innominate artery (n=7), left common carotid artery (n=10), and LSA (n=11). All patients underwent computed tomography before discharge, at 1, 6, and 12 months, and yearly thereafter.. Technical success was 100%. One (3.8%) perioperative death was due to a cerebral hemorrhage. No major stroke was registered, but 3 (11.5%) minor strokes occurred (all resolved). Paraparesis developed in 2 (7.7%) patients. Median follow-up was 36.8 months (range 1-131), during which an additional 4 (15.4%) patients died, but only 1 death was aneurysm-related. Chimney graft patency was 89.3% (25/28); an asymptomatic fracture was found in a patent chimney stent-graft at the 18-month follow-up. The type I endoleak rate was 23% (n=6); 3 endoleaks associated with aneurysm sac enlargement were treated.. The chimney technique for aortic arch pathologies is safe and feasible and may be an option in patients considered at high risk for surgery or who are ineligible for conventional TEVAR, especially in the emergency setting. Concern persists regarding type I endoleak, and long-term follow-up remains mandatory.

Penetrating ulcer of the aorta has been recognized as a distinct aortic disorder, defined by the ulceration of an atherosclerotic plaque. The lesion has the potential to evolve acutely into aortic rupture, but chronic pictures are possible. Late evolution into rupture, frank aortic dissection and progressive aortic enlargement have been documented. We discuss different modalities of presentation on the basis of recent clinical cases. As the optimal treatment, either surgical (open or endovascular) or medical, is based on a correct diagnosis, we highlight the importance of including aortic ulcers in the differential diagnosis of chest pain. Although endovascular treatment can be advisable in cases with favorable anatomic condition and in patients with multiple comorbidities, the open surgical option should be available given the heterogeneous location and clinical scenarios of these lesions.
