Endovascular treatment of acute type B dissection and Kommerell's diverticulum.

ABSTRACT

A 59-year-old man presented with severe hypertension and resistant interscapular pain. Transesophageal echocardiography and computed tomographic angiogram demonstrated acute type B dissection associated with aberrant right subclavian artery with 3.5 cm Kommerell's diverticulum. Open repair was deemed to be high risk to elevate perioperative mortality and morbidity of this surgical technique. Therefore the patient was managed with an endovascular procedure after 14 days of medical therapy because of resistant thoracic pain. We did not observe intraoperative or perioperative mortality and right arm ischemia or symptomatic subclavian steal.
