Do aortic necks of ruptured abdominal aneurysms dilate more than asymptomatic aneurysms after endovascular repair?
Aneurysm necks in patients with ruptured aneurysms are larger and dilate at a greater rate than those with nonruptured aneurysms. The accelerated rate of expansion in some patients must be borne in mind during follow-up and in secondary endovascular interventions and conversion to open surgery.
Coexistence with empty sella-arachnoid cyst raises the possibility of cerebrospinal fluid inbalance in the etiology.
