title: Iliopsoas haemorrhage in patients with haemophilia: results from one centre.
abstract: Iliopsoas haematoma is a well-recognized complication of haemophilia, and is considered as potentially life threatening and significantly associated with morbidity. There are only rare reports on the incidence or outcomes of iliopsoas bleeding since the widespread usage of modern therapies for haemophilia. In this study, we present the experience of Ege University Haemophilia Centre with iliopsoas bleeding and its early and late complications. We reviewed 146 haemophiliacs (106 haemophilia A, 40 haemophilia B). Fourteen iliopsoas bleeding episodes were identified in eight haemophiliacs. Three patients (37%) had one episode, four (50%) had two episodes and one (13%) had three episodes. Two patients had a high titre inhibitor against factor VIII and accounted for three bleeding episodes (21%). We did not observe any episodes in six patients receiving prophylaxis. Iliopsoas haematomas were confirmed by ultrasonography in all patients. In physical examination, the most common symptoms were thigh, hip and groin pain, hip flexion contracture, abdominal tenderness and paraesthesia in the distribution of the femoral nerve. The mean duration of therapy with clotting factor concentrate was 7.8 +/- 1.6 days. The mean duration of hospitalization was 4.8 +/- 2.0 days. All patients started to receive a physical therapy program 6.0 +/- 2.4 days after the initiation of haemostatic therapy which lasted 20.0 +/- 6.0 days. Ultrasonographic findings related to iliopsoas haematoma disappeared in all patients within 3 months from the initial episodes. Only in one patient with mild haemophilia A, heterotopic bone formation (myositis ossificans) developed as a long-term complication. In conclusion, pain around the hip joint, femoral neuropathy and hip flexion contracture in a patient with haemophilia should alert the physician to the possibility of an iliopsoas haematoma. Early and effective factor replacement therapy is essential in the prevention of the complications.
