Type A aortic dissection can develop during TEVAR or even years after TEVAR. Careful operative procedures and follow-up should be mandatory for patients with aortic dissection as TAAD seems to occur more frequently among these patients.

Endovascular repair of SAAs using stent grafts appears to be safe and effective. In terms of preserving the blood flow and avoiding splenic infarction, it may be superior to coil embolization. Even in a case with aneurysm infection, stent graft repair may be an acceptable method to minimize invasion of concomitant surgical intervention.

A total of 576 patients underwent endovascular aneurysm repair using main body devices for treatment of abdominal aortic aneurysms or iliac artery aneurysms. During follow-up, type IIIb endoleaks caused by fabric tear occurred in six patients (1.0% [6/576]). The device used was Zenith (Cook Medical, Bloomington, Ind) in five cases and Talent (Medtronic, Santa Rosa, Calif) in one case. All endoleaks were close to the flow divider of the main body devices. The distance between the lower renal artery and the top end of the contralateral leg was 53 ± 14 mm. Bell-bottom-shaped Excluder (W. L. Gore & Associates, Flagstaff, Ariz) legs were placed parallel from the top of the main body device through both legs to treat these endoleaks. In two patients, coil embolization was required to treat gutter endoleaks. Postoperative computed tomography showed the obliteration of type IIIb endoleaks in all patients. Our technique may be an acceptable method for treatment of type IIIb endoleaks, especially when they occur near the flow divider.
