Characteristics and Management of Free Flap Compromise Following Internal Jugular Venous Thrombosis

Purpose Free flap compromise after internal jugular venous thrombosis (IJVT) occurs fairly infrequently in oral and maxillofacial rehabilitation and reconstruction but could seriously affect the patient’s postoperative recovery. The aim of this study was to analyze and discuss the characteristics and management of such flap compromise. Patients and Methods The authors performed a retrospective case series of 13 patients who underwent reconstruction of oral and maxillofacial defects with anterolateral thigh flaps and developed flap compromise from IJVT from July 2014 through December 2016 at the Second Xiangya Hospital of Central South University (Changsha, China). The clinical features of flap compromise are described, and the precautions and improvement measures are reported. Results All 13 patients were men with an average age of 50.3 years. Flap compromise caused by IJVT occurred on postoperative days 3 to 7, of which 2 flaps were salvaged (15.4%) and 11 flaps failed completely after immediate urgent re-exploration. Four patients presented with orocutaneous fistula after salvage surgery that healed well after a period of wound dressing. Conclusions Because of the late occurrence and low salvage rate of flap compromise caused by IJVT, intensive flap monitoring after reconstruction surgery is necessary for patients with free flap transfer.
