Endovascular Repair vs Medical Therapy for Uncomplicated Acute Type B Dissection: Aortic Remodeling.

ABSTRACT:

Background

The optimal initial management for uncomplicated acute type B aortic dissection (uATBAD) remains unclear. We evaluated 1-year aortic remodeling and clinical outcomes of thoracic endovascular aortic repair (TEVAR) vs exclusively optimal medical therapy for uATBAD.

Methods

Patients with uATBAD were retrospectively grouped by initial treatment modality, with 52 patients treated with TEVAR and 142 with optimal medical therapy. Clinical outcomes and aortic remodeling were compared at presentation and 1-year follow-up. Aortic remodeling parameters, including change in true lumen diameter, full lumen diameter, and true lumen index, and extent of false lumen thrombosis were assessed at 12 thoracoabdominal levels and compared between treatment groups.

Results

TEVAR
