[Hematoma of the iliac psoas muscle. 29 cases].

We present 29 cases of haematoma of the iliac psoas muscle, following anticoagulant treatment and review 158 cases so far published. In 60 p. 100 of cases, the anticoagulant was some form of intravenous or subcutaneous heparin; prescribed in 40 p. 100 of cases for venous thrombosis followed rapidly by pulmonary embolism, in half the cases between the 3rd and the 14th day. Hypocoagulation was excessive in 64 p. 100 of the cases. Clinically the onset is marked in all cases by a violent pain in the territory of femoral nerve, anaemia (40 p. 100) psoïtis (32 p. 100) and iliac mass (51 p. 100), ecchymosis (13 p. 100) and particularly 23 among 29 cases an early or late femoral paralysis. The clinical diagnosis has been confirmed by echography 21 cases an or CT scan (7 cases). Our approach has been definitely surgical. The surgical procedure carried out in 20 p. 100 of the cases published, and in 23 of our ones, relieves the pain, provides for an early efficient physiotherapy, and a regression of the femoral paralysis, much more rapidly and completely than in the absence of surgery. The anatomical lesions, and the condition of the femoral nerve are described in the operative records, account for that evolution and explain our position. Traumatic and hemophilic have evocated.
