Endovascular Treatment for Acute Type B Aortic Dissection Involving a Right-sided Aortic Arch and Kommerell's Diverticulum: A Case Report and Review of the Literature

Abstract

Background: Aortic dissection involving a right-sided aortic arch (RAA) associated with Kommerell's diverticulum is extremely rare and remains a complicated entity for surgical therapy because of its anatomical characteristics. Fewer than 40 cases have been reported in the English language literature to date.

Methods: We reported a case of 69-year-old male patient who presented with acute type B aortic dissection involving an RAA associated with Kommerell's diverticulum, a stent-graft was accurately deployed and embolization of the left subclavian artery. In addition, a review of the literature was performed to examine its clinical presentation and the efficacy of management strategies.

Results: One year follow-up showed positive aortic remodeling with exclusion of Kommerell's diverticulum and thrombosis of the false lumen.

Conclusions: An aortic dissection involving an RAA associated with Kommerell's diverticulum is an extremely rare condition. Endovascular therapy is technically feasible when the dissection involves this unusual vascular malformation.
