Abstract:
Objective To discuss the endovascular interventional treatment of complicated splenic artery aneurysms(CSAA)and its clinical efficacy.Methods The clinical data of 15 patients with CSAA,who were admitted to authors'hospital to receive treatment between January 2013 and December 2022,were collected.The clinical manifestations included rupture with bleeding(n=2),splenic aneurysm originating at the proximal end of the normal splenic artery(n=3),splenic aneurysm originating from the superior mesenteric artery-splenic artery co-trunk(n=4),and splenic aneurysm originating from the celiac trunk-superior mesenteric artery co-trunk(n=6).According to the origin of the splenic aneurysm and the size of aneurysmal cavity,the following endovascular treatment methods were employed:① coil embolization of aneurysmal cavity,②combination embolization of the outflow tract,aneurysmal cavity and inflow tract,③covered stent implantation for intraluminal isolation,and ④bare stent-assisted spring coil embolization and combination therapy with multiple approaches.The medium-term and long-term efficacy of endovascular interventional treatment were analyzed.Results A total of 15 aneurysms were detected in the 15 CSAA patients,the mean diameter of aneurysmal cavity was 1.8-3.2 cm(2.5±0.4 cm),and the success rate of endovascular treatment was 100％.The mean follow-up period was(22.8±10.2)months.In 13 patients(86.7％)the splenic artery aneurysm remained thrombosis with no enlargement of the aneurysmal cavity.One patient had to receive endovascular interventional treatment as the aneurysmal cavity continued to enlarge.One patient developed covered stent occlusion as the patient did not take drugs regularly,and no hepatic or intestinal ischemia,or death occurred during the follow-up period.Asymptomatic focal splenic infarction occurred in 5 patients.Conclusion For CSAA with different anatomical variation origin,endovascular interventional treatment is clinically feasible,safe and effective.
