Purpose:
To review a 10-year experience with endovascular embolization of visceral artery aneurysms.
Methods:
Twenty-five patients (13 men; mean age 52.1 years, range 31-80) presented with VAAs of varying locations and etiologies: 10 splenic, 3 gastroduodenal, 2 pancreaticoduodenal, 3 hepatic, 3 superior mesenteric, 2 celiac, 1 left gastric, and 1 jejunoileal. Ten patients were asymptomatic; 7 aneurysms were ruptured. Transcatheter coil embolization was the treatment of choice in all patients.
Results:
Coil placement was initially (<7 days) successful in 23 (92%) patients. One superior mesenteric artery aneurysm remained perfused, and recurrent bleeding occurred 2 days after intervention in 1 case, but repeated embolization excluded the aneurysm. One patient with necrotizing pancreatitis died from sepsis 10 days after endovascular treatment and surgery (4% 30-day mortality). Long-term follow-up revealed excellent results after an average 48.7 months (range 14-75) with only 1 recurrence after 12 months.
Conclusions:
Embolotherapy is the treatment of choice in visceral artery aneurysms, regardless of etiology, location, or clinical presentation.
