Minimally invasive treatment of portal pseudoaneurysm in a haemophiliac after knee arthroscopy

摘要

The formation of a pseudoaneurysm or ‘false’ aneurysm is a rare vascular complication of arthroscopic surgery. Its occurrence is even more uncommon in the background of a clotting disorder. We present a case of a recreational athlete with a history of haemophilia, who developed a pseudoaneurysm over an arthroscopic portal site following arthroscopic-assisted anterior cruciate ligament reconstruction. The lesion was treated successfully with image-guided thrombin injection. We discuss the association between haemophilia and pseudoaneurym formation as well as prevention methods and treatment options.
