title: Successful endovascular treatment of aneurysm sac hygroma after open abdominal aortic aneurysm replacement: a report of two cases.
abstract: We report two patients with perigraft hygromas after open abdominal aortic aneurysm replacement treated with relining the existing graft by covered stents with subsequent decrease in the size of the hygroma and disappearance of symptoms on follow-up. To our knowledge, these two patients are the first reported cases of successfully treated perigraft hygromas after open repair of abdominal aortic aneurysm using endograft relining of the existing grafts. This endovascular treatment avoids the need for aortic graft excision and replacement, which may be a challenging undertaking.
