Abstract:
Objective To compare selective coverage and chimney technology of the left subclavian artery (LSA) in thoracic endovascular aortic repair (TEVAR).Methods Eighty-one cases were retrospectively reviewed from January 2005 to January 2013 with two different management of the LSA during TEVAR:selective coverage (SC) vs chimney (C).Technical success rates,operating time,endoleaks,and perioperative cerebrovascular accidents,spinal cord ischemia (SCI),left arm ischemic symptoms and mortality were analyzed.The survival rate was also evaluated.Statistical analysis was performed using the x2 test,t-test and Kaplan-Meier survival curve.Results There were 37 patients in group SC and 34 in group C.Operating time was (61 ± 22) min for SC,and (101 ± 20) min for C (P =0.000) ; left arm ischemic symptoms occurred in 23.4％ in group SC,and 2.9％ in group C (P =0.011).Technical success rates were 100％ and SCI were 0 for both SC and C.Endoleaks,perioperative cerebrovascular accidents,and mortality were similar between the two groups.Conclusions During TEVAR,selective coverage of the left subclavian artery is safe,effective; meanwhile,chimney technology is safe,effective for patients whose left subclavian arteries need revascularization.
