Abstract:
Objective To investigate the feasibility and effect of intentional occlusion of the left subclavian artery (LSA) in endovascular aortic repair EVAR of thoracic aortic disease.Methods The cases,who needed occlusion of the LSA in EVAR of thoracic aortic disease,were examined cerebral circulation,carotid artery,vertebral basilar artery and circle of Willis.If the vertebral artery had a good blood pathway,and carotid artery and circle of Willis had no stenotic,we occluded the LSA directly in EVAR,and observed the brain and upper limb ischemia complications postoperation.Results Among 40 cases who were occluded the LSA directly in EVAR,28 cases were successful with no neurological complications and left upper limb ischemia symptoms postoperation,12 patients with mild symptoms of subclavian steal syndrome and neurdogical complications,but none required and secondary surgical intervention.Conclusions Prior to intentional LSA occlusion,attention must be paid to potential supraaortic variants and pathologies.Only in this way,it was safe and effective to occlude the LSA in EVAR of thoracic aortic disease.
