【 摘 要 】

BackgroundVascular injury is a very rare complication following arthroscopic knee surgery. This is the first report of pseudoaneurysm at the saphenous branch of the descending genicular artery complicating semitendinosus tendon harvest in arthroscopic anterior cruciate ligament reconstruction.Case presentationA 19-year-old male had developed large ecchymosis, focal swelling and tenderness around his posteromedial knee after an arthroscopic anterior cruciate ligament reconstruction. Compartment syndrome of the lower leg and deep vein thrombosis were ruled out. A pseudoaneurysm formation was confirmed through an angiography and coil embolization was performed. At one year follow up, the patient reported improved functional outcome with good stability of the knee. However, mild paresthesia over the posteromedial calf was noted due to the compression injury of the saphenous nerve by the hematoma.ConclusionsThe pseudoaneurysm was presumed to result from accidental vascular injury while dissecting the accessory bands of the semitendinosus and was successfully treated by coil embolization. Care must be taken to section the expansions of the hamstring tendon, especially when the patient presents with underlying coagulopathy or vascular disease.
