- Type II Endoleaks, Left-Arm Complications, and Need of Revascularization after Left Subclavian Artery Coverage for Thoracic Aortic Aneurysms Endovascular Repair: A Systematic Review(2017) BELCZAK, Sergio Quilici; SILVA, Erasmo Simao; KLAJNER, Rafael; PUECH-LEAO, Pedro; LUCCIA, Nelson DeBackground: The status of the left arm, the need of revascularization, and the occurrence of type II endoleakes from de left subclavian artery (LSA) after intention LSA coverage for thoracic aortic aneurysm endovascular repair need to be better understood. This systematic review was developed for contributing with such issue. Methods: Systematic literature review of studies published from January 2000 through December 2015 identified 7 studies comprising 201 patients submitted to elective endovascular repair for thoracic aortic aneurysms requiring intentional LSA coverage. Outcomes of interest included left-arm complications (ischemia, symptoms of claudication, and subclavian steal syndrome [SSS]) requiring postoperative revascularization of LSA, as well as endoleaks from the subclavian artery requiring postoperative embolization of LSA. Results: Left-arm complication rate was 4.5% (9 patients), requiring postoperative revascularization of LSA in 1 case (0.5%) of SSS. Type II endoleaks from the subclavian artery requiring postoperative embolization of LSA were reported in 2 cases (1.0%). Conclusions: Low-quality evidence suggests very low rates of arm complications with need of LSA revascularization and of type II endoleaks requiring embolization in elective endovascular treatment of thoracic aortic aneurysms with intentional coverage of LSA without prophylactic revascularization of LSA.
