Staged endovascular treatment of aneurysmal progressive development of an intercostal arteries island reimplanted with the loop-graft technique.

Abstract

A staged endovascular strategy was used to treat the aneurysmal evolution of the aortic island including intercostal arteries reimplanted in a loop-graft, following thoraco-abdominal aortic open repair in a young patient diagnosed with Marfan syndrome. First, selective coil embolization of patent intercostal arteries was performed in 2 separate sessions, to minimize the risk of spinal cord ischaemia. Then, the aneurysm was successfully excluded occluding the loop graft with 2 PTFE-membrane vascular plugs.
