Diagnosis and treatment for 17 isolated iliac aneurysms

Abstract

Objective To summarize the experiences in surgical and endovascular treatment for isolated iliac artery aneurysm.Methods Data of 17 cases with isolated iliac artery aneurysm were reviewed and analysed retrospectivel.17 cases were examined with color Doppler ultrasounograpy preoperatively,13 cases underwent computed tomographic angiography (CTA),2 cases did digital subtraction angiography (DSA).Artificial graft interposition were performed in 10 cases with unilateral iliac artery aneurysm,endovascular repair were performed in 6 cases.One case was treated by artificial graft interposition after a failed endovascular repair. Results Preoperativaly correct diagnosis was established in all 17 cases,and they were cured after operation.The average operative time was (3.7 ± 1.2) h in group of surgical operation,and ( 1.4 ±0.7) h in group of endovascular treatment (P ＜0.05).The length of hospital stay was ( 16 ± 5 ) d for the group of surgical operation,and ( 9 ± 4 ) d for endovascular treatment ( P ＜ 0.05 ).The percentage of blood transfusion was 72.7％ ( 8/11) in the group of surgical operation,and 16.7％ (1/6) in the group of endovascular treatment.There were a ureteral injury and a ectopic embolism happened during the procedure.There were 2 hip claudication and 2 type Ⅰ endoleaks after operation,which subsided after 3 months. Conclusions Artificial graft interposition or endovascular repair is effective treatment for isolated iliac artery aneurysm which has the advantage of minimally invasiveness and rapid recovery.
