Pseudoaneurysm is a rare complication of ankle sprain, with 18 case reports published in the current literature. In the vast majority of the cases, they were treated surgically. We present 3 cases of pseudoaneurysm following ankle sprain, treated by nonsurgical methods in 2 cases, and spontaneously healed in another. The diagnosis was made between 2 and 4 weeks after traumatism, by ultrasonography and arteriography in 2 cases, and only by ultrasonography in a third case. The pseudoaneurysms originated respectively from the perforating fibular artery, the dorsal pedis artery, and a lateral malleolar artery. Largest diameters of the pseudoaneurysms ranged from 2.4 to 6 cm. Patients were successfully treated by thrombin injection in a case and by coil embolization in another. Spontaneous thrombosis was demonstrated at follow-up in the third case. These cases suggest that a nonsurgical treatment can be considered for pseudoaneurysms complicating ankle sprains.
