Abstract:
Objective To evaluate the feasibility of chimney technique during thoracic endovascular aneurysm repair(TEVAR) in aortic arch lesions. Methods The stent-graft was deployed covering super arch branch artery in arch lesions in case there was not enough landing zone. A chimney stent was put in the super arch branch artery. We retrospectively analyzed the data of this group, aiming at summarizing the indications, methods, results and complications of chimney technique. Results From August 2004 to August 2009, 27 aortic arch lesions were treated by TEVAR with chimney stent, male/female ratio was 25/2, average age was 67. 2 ±3. 8 years, including3 chimney stents for innominate artery, 11 chimney stents for left common carotid artery and 13 chimney stent for left subclavian artery. Type I endoleaks were encountered in 18. 5% (5/27) of this group by final angiogram. Left common carotid artery dissection was caused by puncture in one case. One patient died of respiratory failure. There was no postoperative stroke nor bleeding. Discharged patients were followed up from 3 to 60 months, averaging at 16. 8 months. There was one death from MI 4 years later. There was minor stroke and left subclavian artery chimney stent occlusion in one each cases during the follow-up. All endoleaks were sealed without stent migration. Conclusion Chimney technique improves the length of landing zone and decreases effectively the endoleak rate.
