Short-term efficacy of unibody single-branched stent in the treatment of lesions involving the left subclavian artery: two-year follow-up outcomes

摘要

The development of thoracic endovascular aortic repair (TEVAR) technology avoids the risk of patients opening the chest and is widely used in Stanford B-type dissection. However, because TEVAR technology has clear requirements for vascular anatomy of the lesion, it limits its application to some patients. In the shortcomings of the proximal anchor zone, coverage of the left subclavian artery (LSA) origin without revascularization during TEVAR appears to have increased risk of stroke, upper extremity ischemia and paraplegia.
