Extra-Anatomic Revascularization of Extensive Coral Reef Aorta

Background Coral reef aorta (CRA) is a rare, potential lethal disease of the visceral aorta as it can cause visceral and renal infarction. Various surgical approaches have been proposed for the CRA treatment. The purpose of this article is to report different extensive extra-anatomic CRA treatment modalities tailored on the patients' clinical and anatomic presentation. Methods From April 2006 to October 2012, 4 symptomatic patients with extensive CRA were treated at our department. Extra-anatomic aortic revascularization with selective visceral vessels clamping was performed in all cases. Results Technical success was 100%. No perioperative death was registered. All patients remained asymptomatic during the follow-up period (62, 49, 25, and 94 months, respectively), with bypasses and target vessels patency. Conclusions The extra-anatomic bypass with selective visceral vessels clamping reduces the aortic occlusion time and the risk of organ ischemia. All approaches available should be considered on a case-by-case basis and in high-volume centers.
