HYBRID SURGERY FOR COMPLEX AORTIC DISSECTING ANEURYSMS

Abstract

Objective: Estimate the safety and results of TEVAR combined with open surgery for extensive aortic dissecting aneurysms.
Methods: Observational, prospective study from August 2013 to May 2017. Patients with extensive aortic dissecting aneurysms are treated with open replacement of the ascending aorta and arch, then TEVAR which was landing on the prothesis to cover the descending disease.
The oversize rate is 20-30%, and the length of landing zone is >= 5cm.
The patients are followed by contrasted CT scan at 1, 3 and every 12 months post-operatively.
Results: N=22 patients, male: female= 17:5. Average of age was 60.8 ± 10.7 years. Concomittent procedures were 1 case of CABG, 1 case of valve-sparing root replacement. Average number of stent is 1.83. 30-day mortality was 4.5%. No endoleak type 1 and survival rate was 21/22.
Conclusions: TEVAR and open surgery is useful and safe for treatment of complex aortic dissecting aneurysms.
