Outcome Comparison of TEVAR with and without Left Subclavian Artery Revascularization from Analysis of Nationwide Inpatient Sample Database

Evaluation of Early and Mid-term Results of TEVAR Procedures with Various Etiology.

“…LSA revascularization before TEVAR, compared with post-TEVAR revascularization, had lower perioperative cardiopulmonary complications. In highrisk patients, endovascular LSA revascularization may be recommended over open surgery [28]. In our study the LSA was closed in 3 patients without revascularization, none of them developed cerebral or left upper extremity ischemia in the long term.…”

Chimney Endografting for Zone 2 Thoracic Endovascular Aortic Repair Using The Reorientation Technique

“…Axillo-axillary bypass may be considered as a suitable alternative and preferred when a concomitant ipsilateral carotid lesion is present, but the primary patency is up to 66% and can increase the complexity of future median sternotomy [11][12][13]. A recent large study demonstrated that endovascular LSA revascularization had lower risk of postoperative mortality, stroke, cardiac, and pulmonary complications compared to open LSA revascularization in the setting of Zone 2 TEVAR [14]. Compared with the hybrid technique, the chimney technique is more advantageous in terms of immediacy, reduced invasiveness, and improved safety [15].…”

Commentary: The benefits of going big: Cost savings and reduced mortality in a national study of proximal aortic repair

“…The National Inpatient Sample (NIS) serves as a valuable resource to identify trends for hospitalized patients within the United States with regard to access, cost, outcomes, and other factors; when weighted, this readily available federal data reflect more than 97% of US patients, and a wide variety of medical procedures are tracked using administrative codes from the International Classification of Diseases (most recently the International Classification of Diseases Clinical Modification, 9th Revision, and International Classification of Diseases Clinical Modification, 10th Revision/ Procedure Classification System). 1 As pertains to aortic surgery, contemporary analyses have largely focused on use and outcome trends for technique-driven and other studies of the descending thoracic, [2][3][4] thoracoabdominal, 5,6 and abdominal aorta 7,8 as well as studies on aortic dissection. [9][10][11] Although considerable effort has been made to better understand practice trends in repair of the distal aorta (ie, the descending thoracic, thoracoabdominal, and abdominal aorta), there are a lack of NIS-based studies that exclusively examine the proximal aorta, namely the aortic root, ascending aorta, and aortic arch.…”
