[Pseudoaneurysm - a rare complication after insertion of a distal locking bolt of an intramedullary femur nail].
A pseudoaneurysm is caused by an extravasal hematoma after vessel injury. Persistent blood supply via the afferent artery can lead to aneurysm growth with potential rupture of the lesion. We present a case of a 27-year-old man who developed three independent pseudoaneurysms after insertion of percutaneous distal locking bolts for static locking of an intramedullary femur nail. Color-coded Doppler sonography and intraarterial subtraction angiography were used to detect the lesion. Successful treatment consisted of endovascular embolization (coiling) with injection of a platinum coil into the aneurysm's supplying vessel. Pseudoaneurysm after fracture or fracture fixation represents a rare complication, but the risk of acute bleeding by pseudoaneurysm rupture should not be neglected.
