Temporary aneurysm neck balloon occlusion during percutaneous thrombin embolization of a superficial femoral artery pseudoaneurysm

HIGHLIGHTS: Thrombin migration.Ultrasonographically guided thrombin injection.Aneurysm neck occlusion with a balloon. ABSTRACT: An iatrogenic pseudoaneurysm of the superficial femoral artery was embolized with ultrasonographically guided thrombin injection. In order to avoid thrombin migration to the limb arteries, during the injection, the aneurysm neck was temporarily occluded, inflating a 5 mm balloon. The balloon was deployed endovascularly with a crossover technique. At six months' follow-up, the pseudoaneurysm remained occluded and the limb arteries were patent.
