title: Femoral nerve palsy after mandibular reconstruction with microvascular iliac flap: a complication under anticoagulation therapy.
abstract: Pharmacological prophylaxis and intervention are used extensively in head and neck reconstructions with microvascular flaps. There is no universally accepted protocol, but the microvascular surgery literature recommends intraoperative anticoagulation with heparin. Here is reported a case of iliacus haematoma with subsequent femoral nerve palsy after the harvest of a microvascular iliac flap for mandibular reconstruction in a patient who had been treated with heparin. The association between femoral nerve palsy and anticoagulant therapy has been well described. It remains unclear as to why the iliacus muscle is particularly vulnerable to intramuscular haemorrhage. Femoral nerve neuropathy is also an uncommon but recognized complication after abdominopelvic surgery. Iliacus haematoma secondary to microvascular surgery has not been previously reported. This case illustrates the need to be aware of this type of complication and its clinical manifestations for patients under anticoagulant therapy in the perioperative period during microvascular reconstructions.
