Bentall procedure for retrograde type A dissection after endovascular repair in type A aortic dissection: A case report.

Abstract

Rationale:The management of retrograde type A dissection (RTAD) after thoracic endovascular aortic repair (TEVAR) for type A aortic dissection (TAAD) has rarely been reported. We report the management of RTAD after TEVAR with in situ fenestration for TAAD.Patient concerns:A 59-year-old man with TAAD had undergone TEVAR with in situ fenestration 4 months prior to presenting to our emergency room complaining of acute chest and back pain. Computed tomography angiography showed RTAD starting from the proximal endograft and extending to the aortic root.Diagnosis:The patient was diagnosed with RTAD.Interventions:We performed only the Bentall procedure, and the patient did not require total arch replacement. We removed the bare spring of the proximal endograft and anastomosed the prosthetic graft with the endograft and the native ascending aortic wall.Outcomes:The postoperative course was uneventful, and the patient remained asymptomatic for 3 years after surgery. Computed tomography angiography at the 3-year follow-up showed no perivalvular or anastomotic leakage.Lessons:RTAD after TEVAR for TAAD was safely and effectively treated by anastomosing the prosthetic graft with the endograft and the native ascending aortic wall instead of total arch replacement.
