Transcatheter coil embolization of splenic artery aneurysms

Objective To explore the clinical application value of transcatheter coil embolization of splenic artery aneurysms.Methods The data of 18 splenic artery aneurysms patients were retrospectively analyzed.There were 14 true aneurysms and 4pseudo aneurysms.There were 6proximal type,4middle type and 8hilar type.After angiography of splenic artery,embolization was performed using general coils,microcoils or mechanically detachable coils.All patients were followed up with enhanced CT or CTA 1week,1,3,9months after the operation,then telephone follow-up was performed monthly.Results The embolization procedure was performed successfully in all the 18 patients.Totally 11 cases underwent isolation technique,4cases underwent packing technique,3cases underwent isolation technique and packing technique.Twelve patients had postembolization syndrome after the operation,among them,8patients had different level of splenic infarction(infarcted volume about 10%—35%);4patients had minor complications.There were no aneurysm enlargement,rupture or recurrence and related complications during the follow-up period.Conclusion Transcatheter coil embolization of splenic artery aneurysms is simple,feasible,safe and effective.
