Intercostal artery's access for type II endoleak embolization.

Endoleaks represent a main issue of endovascular approach of thoracic aorta diseases and their treatment continue to be challenging. According to some authors, type II endoleaks sustained by intercostal arteries should not be treated because of the technical difficulties. However, the persistence of a pressurized aneurysmal may confer an ongoing risk of enlargement and/or aortic rupture. We describe the successful treatment of type II endoleak in 2 patients with an intercostal artery's access. In both cases, the endoleak was discovered during follow-up and was treated with its direct coil embolization under local anaesthesia.
