Objective  To investigate the technical feasibility and effectiveness of intraoperative sac embolizaion with coils and fibrin glue for preventing type Ⅱ endoleak after endovascular aneurysm repair (EVAR). Methods  A patient with abdominal aortic aneurysm (AAA), which had high risk of type Ⅱ endoleaks, was treated with combined packing of coils and fibrin glue in order to prevent type Ⅱ endoleak after EVAR. Percutaneous catheter preset and balloon occlusion were used to ensure accurate packing. Results  At the end of the operation, the angiography showed that the blood flow of the stent and distal artery was unobstructed, there was no type Ⅰ and Ⅲ endoleaks, and delayed angiogram showed no collateral circulation of aneurysm. The procedure was successful. The operative duration was 120 min and the blood loss was only 20 mL. No complications such as colonic ischemia and ectopic embolism occurred, and the patient was discharged on 3 days after operation. At 6 months after follow-up, the computerized topographic angiography showed that the aneurysm cavity was completely thrombotic, without type II endoleak, and the diameter and volume of aneurysm were reduced. Conclusions  The technique of intraoperative sac embolizaion with coils and fibrin glue during EVAR is safe and effective to prevent postoperative endoleaks, which is simple and feasibility. Intraoperative indwelling catheter and balloon blocking are the key points of successful implementation of this technique.
