Hybrid Surgery for Multiple Visceral Artery Aneurysms: A Case Report

Abstract

We present a case with multiple visceral artery aneurysms that were treated with a hybrid approach involving both surgical and endovascular treatment. The patient was a 48-year-old female. She was diagnosed with multiple visceral artery aneurysms including 2 splenic artery aneurysms, celiac artery aneurysm, and bilateral renal artery aneurysms during an examination for loss of appetite. With regard to 2 splenic artery aneurysms, the proximal aneurysm was treated surgically, whereas the peripheral aneurysm that was located deeply in the abdomen was treated with coil embolization. The celiac artery aneurysm located at the bifurcation of the common hepatic artery and splenic artery, an intracranial aneurysm clip was used. The left and right renal aneurysms were resected and renal arteries were reconstructed surgically. The postoperative course was uneventful. The pathological diagnosis of all aneurysms was segmental arterial mediolysis. The reconstructed vessels were patent without stenosis or recurrence at 1year after the operation. Hybrid treatment involving surgical resection, endovascular coil embolization, and obliteration with clips was useful in the treatment of multiple visceral artery aneurysms.
