OBJECTIVE Kommerell diverticulum with aortic dissection involving aortic arch is a rare but troublesome condition. The purpose of this study is to summarize the experience and strategy of surgical treatment. METHODS From November 2015 to January 2018, seven consecutive patients underwent surgical treatment in our institution. Three patients with acute type A aortic dissection and one patient with acute type B aortic dissection received total arch replacement and frozen elephant trunk (FET) implantation through median sternotomy. Three patients with chronic type B aortic dissection underwent total aortic arch and descending aorta replacement through median sternotomy and lateral thoracotomy. RESULTS There were seven male patients whose median age was 42.3 ± 11.7 (from 14 to 54) years old. There was no perioperative death in this study. One patient had postoperative critical illness polyneuropathy and required prolonged mechanical ventilation (485 hours) and recovered finally. Follow up was completed for all seven patients with a median follow-up time of 7 (3-46) months. One patient with type A dissection developed aneurysm of the descending aorta distal to the FET and received reintervention. No clinical events and abnormal computed tomography manifestations were found in the other seven patients. CONCLUSIONS Total arch replacement and FET through single median incision is a reliable method for Kommerell diverticulum associated with acute dissection involving arch. For Kommerell diverticulum associated with chronic type A or B aortic dissection involving aortic arch, graft replacement by double or single incision is safe and appropriate.
