Abstract
Objective To investigate the treatment of visceral artery aneurysm (VAA) and its safety and efficacy. Methods Clinical data of 18 patients with VAA admitted at Department of Vascular Surgery, Hainan General Hospital from 2012 to 2018 were retrospectively analyzed. All cases were solitary aneurysm (10 cases of true aneurysm, 8 cases of pseudoaneurysm) , including 7 cases of splenic artery aneurysm, 3 cases of renal artery aneurysm, 4 cases of superior mesenteric artery aneurysm, 2 cases of gastroduodenal artery aneurysm and 2 cases of hepatic artery aneurysm. Endovascular treatment was performed in 13 cases, including 9 cases of embolotherapy and 4 cases of stent-implantation. Open surgery was performed in 5 cases, including 3 cases of aneurysmectomy plus artery reconstruction and 2 cases of aneurysmectomy. Results There were 13 cases of endovascular treatment, the success rate was 92.3% (12/13) , and the success rate of laparotomy was 100% (6/6) . After 6 to 48 months follow-up, digital substraction angiography and CT data before and after treatment were compared and analyzed. All aneurysms were disappeared or completely isolated from the circulation, no rupture, hemorrhage, recurrence, or infection were observed. No severe complications or death were found, splenic infarction symptoms occurred in 2 cases after surgery. No abnormalities of liver and kidney functions were found after treatments of hepatic and renal aneurysms. There were no obvious symptoms of pancreatitis and intestinal ischemia after operation for gastroduodenal artery aneurysms and superior mesenteric artery aneurysms. Conclusion VAA is unpredictable and complicated. There is no constant surgical method. Sufficient analysis and evaluation should be made according to the manifestations and imaging characteristics. As long as it is applied properly, it is safe and effective for both open surgery and endovascular surgery. Most patients with VAA could be given endovascular treatment as primary procedure. It is also feasible to convert to open surgery when endovascular treatment failed. Key words: Visceral artery aneurysm; Open surgery; Interventional therapy
