Definitive reconstruction was made using a free latissimus dorsi flap and split-skin grafts. One week before the surgery, the plasmapheresis protocol and blood transfusion were administered, in order to achieve a hemoglobin S level of ≤ 30%. Intraoperatively, the flap pedicle was rinsed with plasminogen activator inhibitor-1 until the thrombolytic agent was obtained from the comitant vein; after the arterial flow had been released, an intravenous bolus dose of heparin(2000 U) was administrated. No vascular complications occurred. Postoperatively, the patient received a 10-d course of hemodilution and a 14-d course of full-dose anticoagulation. After 8 mo postoperatively, the patient was able to walk and run, and showed complete wound healing. This case indicates that sickle cell disease is not a contraindication to free tissue transfer; however, the complications, their rate and overall outcomes for these cases are not yet clear. Herein, we provide an algorithm based on our clinical experience in this type of case and treatment, including several recommendations that may help to reduce thrombosis risk and systemic complications.展开更多
