dehiscence
Pronunciation: dee-HISS-ents
Partial or complete separation of surgical wound edges, particularly concerning sternal wound healing.
Full Definition
Wound dehiscence refers to the partial or complete breakdown of surgical incision sites following cardiac surgery. In the context of cardiac surgery, this most commonly affects the sternal wound after median sternotomy, where the sternum may separate despite wire closure. Dehiscence can range from superficial skin separation to deep sternal wound infection with complete sternal separation (mediastinitis). Risk factors include diabetes, obesity, immunosuppression, poor nutritional status, and surgical site infection. Management depends on the depth and extent of dehiscence, ranging from local wound care to complex reconstruction with muscle flaps.
Usage
Usage note: Serious complication requiring prompt recognition and appropriate management. Distinguish from simple infection.
