Abstract

Purpose: To evaluate the safety and feasibility of the in situ needle fenestration (ISNF) technique for reconstruction of the left subclavian artery (LSA) during thoracic endovascular aortic repair (TEVAR) of complicated aortic arch pathologies. Materials and Methods: A retrospective review was conducted from January 2014 to December 2019 of 50 patients (mean age 60.2±11.1; 45 men) who underwent ISNF to revascularize the LSA during TEVAR. Twenty-one of the patients also required revascularization of the left common carotid artery (LCCA; n=19) and innominate artery (IA; n=2) using physician-modified in vitro fenestration. Overall, 73 supra-aortic branches were targeted for revascularization. Results: ISNF was successful in 48 patients (96%); one LSA could not be stented and a tortuous LSA prevented the needle from fenestrating the graft. No perioperative major adverse event occurred. There were no type I and 4 type III endoleaks (8%), 3 of which occurred among the first 20 cases. Types II and IV endoleaks were found in 3 (6%) and 6 (12%) cases, respectively; all disappeared during a median follow-up of 15 months (range 3–66). One death (2%) occurred within 12 months due to cerebral hemorrhage. Two patients (4%) required open reinterventions at 6 and 62 months. Conclusion: ISNF for revascularization of the LSA during TEVAR seems to be feasible with acceptable midterm outcomes. The learning curve and evolving patient selection criteria affected technical success, complications, and the need for reinterventions. Long-term durability requires further evaluation.
