Abstract:
OBJECTIVE:To explore the safety and efficacy of "chimney graft" technique during thoracic endovascular aneurysm repair (TEVAR) in aortic arch lesions.
METHODS:Th e methods, results and the incidence of complications in 25 patients, who received "chimney stent" therapy for aortic arch disease, were reviewed and analyzed.
RESULTS:From August, 2010 to August, 2014, 25 aortic arch lesions were treated by TEVAR with "chimney stent", 18 patients were male and 7 were female. The average age was 38-78(65±5.8) years old. Five patients received "chimney stents" for left common carotid artery, while 20 patients received "chimney stent" for left subclavian artery. Three cases showed small amount of Type I leak under immediate postoperative angiography without treatment. The leak was disappeared 1month later. Two patients appeared left upper limb weakness and one of them showed dizzinesss simultaneously. Both of them recovered gradually in follow-up process. Th ere was no limb ischemia or necrosis. Th e locations of aortic and "chimney stent" were stable without any migration and leak complications.
CONCLUSION:"Chimney graft" technique is a safe and effective treatment for aortic arch lesions due to lack of proximal anchoring zone. The follow up results in a short-term is satisfied.
