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.
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.
