Sternal wound dehiscence after transverse thoracosternotomy for bilateral lung transplantation: report of a case

Transverse thoracosternotomy is the standard approach for bilateral lung transplantation (BLT), but all measures must be taken to prevent breakdown of the sternal wound. We report a case of sternal dehiscence with subcutaneous and peristernal air collections, which occurred 1 month after BLT, performed through a transverse thoracosternotomy, in a 38-year-old man. Surgical exploration revealed that the sternal wires had cut through the bone, causing air leakage of both lungs. We repaired the injured lungs and reapproximated the sternum; however, a pseudo-joint of the sternum developed postoperatively. We report the clinical course of this post-transplant patient to highlight the impact and management of sternal dehiscence.
