A study on treatment of visceral artery aneurysm

Objective To evaluate open and endovascular procedures for the treatment of visceral arterial naeurysms.Methods Clinical data of 93 cases were reviewed from Jan 2001 to Jan 2011,including 47 males,and 46 females.Splenic artery aneurysm in 45 cases,superior mesenteric artery aneurysm in 15 cases,renal artery aneurysms in 10 cases,common hepatic artery aneurysm in 7,celiac artery aneurysms in 11 and gastroduodenal artery aneurysm in 5 cases.All cases had either open procedures or endovascular procedures after comprehensive evaluation.Results Surgical open procedures were performed on 34 cases,and endovascular procedures were performed on 59 cases.The perioperative complication rate were 52.9％ and 13.6％ for open and endovascular groups respectively.The mean follow-up time was 36.8 months ( 11 months to 10 years).1 -year survival rate and 5-year survival rate were 100％and 60.6％ in open surgery group,compared with 100％ and 84.5％ in endovascular group.Conclusions Endovascular repair is effective for visceral artery aneurysm with lower perioperative complication rate and better long-term survival rate.
