Endovascular Treatment of a Ruptured Pseudoaneurysm of the Intercostal Patch after Descending Aortic Aneurysm Repair

2020 
Anastomotic pseudoaneurysm and patch aneurysm are life-threatening complications following thoracoabdominal and descending thoracic aortic aneurysm (DTAA) repair. The aortic wall tissue is fragile in patients with Marfan syndrome, who are at high risk of anastomotic pseudoaneurysm and patch aneurysms. We experienced a rare case of ruptured pseudoaneurysm of the intercostal patch after DTAA repair in a patient with Marfan syndrome. A hematoma was separated from the pseudoaneurysm caused by adhesion of the left lung after DTAA repair, which made diagnosis difficult. To prevent type II endoleak and achieve thoracic endovascular aortic repair, we treated the patent intercostal arteries by embolization.
