Endovascular therapy for visceral artery aneurysms.

BACKGROUND

The aim of this study was to report outcome and complications of endovascular therapy for visceral artery aneurysms (VAA).

METHODS

Forty endovascular procedures for VAAs were performed in 33 patients between 2009 and 2014.

RESULTS

The main indications was size (N.=15), bleeding (N.=14) and mycotic aneurysm (N.=3). The splenic artery was the most common artery of true aneurysms (11/16) and pseudo aneurysms due to pancreatitis (5/14). The median size of the true aneurysms was 24 mm (range 15-65). Two ruptures of true VAAs occurred in elderly. Five patients had eleven synchronous artery aneurysms at CT abdomen. Local anesthesia was used in 93%. Coil embolization were performed without (N.=15) and with (N.=14) other techniques. Nine aneurysms were excluded with stent grafts and patency rate was 88%. Coil embolization was complicated by five spleen infarctions, managed with splenectomy (N.=1) and drainage of abscess (N.=1). One patient died, unrelated to the VAA.

CONCLUSIONS

Endovascular therapy of VAAs, irrespective of etiology, was an effective treatment option.
