Progressive Wound Necrosis Associated With Postoperative Thrombocytosis in Mastectomy and Immediate Breast Reconstruction Surgery: Report of a Case

A 37-year-old who underwent splenectomy for motor vehicle accident-related injuries was diagnosed with stage IIA carcinoma of left breast 12 years later. She underwent bilateral mastectomy and bilateral immediate unipedicle TRAM flap reconstruction. Her preoperative platelet counts ranged from 332 to 424 K/cmm. Intraoperative fluorescein confirmed mastectomy flap viability. On postoperative day 1, platelet count was 374 K/cmm and all suture lines appeared benign. The patient was discharged 3 days later with healthy appearing tram flaps and slight epidermolysis in the abdominal region. Over the next 2 weeks, both the mastectomy flaps and the abdominal region underwent progressive necrosis as the platelet count increased to 1390 K/cmm. Aspirin therapy was instituted at this time. The TRAM flaps remained completely viable. Eighteen days later, the patient required wound debridement with secondary closure of the breast wounds. Platelet count peaked at 1689 K/cmm 2 days later (postoperative day 38). The wounds deteriorated again and were managed conservatively. Two months after mastectomy, the first area of spontaneous healing was documented (platelet count 758 K/cmm). Ultimately, wounds healed as platelet count reached its preoperative baseline. We hypothesize that an abnormal secondary thrombocytosis at subdermal plexus level caused problematic healing in this patient's mastectomy and abdominal flaps.
