Descending aortic banding for re-rupture of retrograde aortic dissection after emergency thoracic endovascular aortic repair.

Conversion to open repair after thoracic endovascular aortic repair (TEVAR) for acute type B aortic dissection is rare, but inevitable. We present a case of an 86-year-old man with ruptured type B aortic dissection after TEVAR. He received a successful stent-graft implantation of the descending aorta without any type of endoleak. After the patient was transferred to the intensive care unit, he went into a shock state. Contrast-enhanced CT revealed a re-rupture of acute retrograde type B aortic dissection. The false lumen was patent and perforated to the left thorax. Left thoracotomy and descending aortic banding was performed. Descending aorta was encircled with a woven Dacron graft at the distal part of the rupture site to compress the patent false lumen. The bleeding was stopped, and the follow-up CT showed false lumen thrombosis. Descending aortic banding is one of the quick and effective open conversion techniques.
