[Emergency Thoracic Endovascular Aortic Repair of Ruptured Kommerell's Diverticulum with an Acute Aortic Dissection].
2016
Abstract This case report describes emergency thoracic endovascular aortic repair (TEVAR) of a ruptured Kommerell's diverticulum associated with a type B acute aortic dissection in a patient with a right aortic arch. A 64-year-old male was admitted with symptoms of sudden paraplegia and shock. The computed tomography imaging showed right aortic arch anomaly, with mirror image branching of the major arteries. The aorta was dissected from the origin of the right subclavian artery to the terminal aorta, with a thrombosed false lumen. Rupture was found in a 6.3 cm aneurysm located in the distal arch, which was diagnosed as Kommerell's diverticulum. We performed emergency TEVAR, and the aneurysm was successfully excluded using deployment of a Gore Tag stent-graft. At 3 months' follow-up, the patient was doing well and showed shrinkage of the aneurysm was confirmed. TEVAR is considered to be a suitable procedure for an emergency aortic catastrophe even in patients with aortic anomaly.
