No funnel plot asymmetry was identified in all analyses. CONCLUSIONS Compared to OSR, EVAR associated with lower perioperative mortality and higher mortality in the mid-term period for intact infrarenal AAA. The superiority of EVAR was absent in the early-term period, and the inferiority of EVAR in the mid-term period disappeared in the long-term and very long-term periods. OBJECTIVES YouTube videos have become a common resource for trainees to learn about surgical procedures. Carotid endarterectomy (CEA) is one example procedure that may be performed by multiple specialties and with a variety of techniques. Little is known about educational content and the representation of vascular surgeons in these videos. We sought to compare the educational quality of CEA YouTube videos, techniques demonstrated, and prevalence of each specialty. METHODS YouTube was programmatically searched for the terms "carotid endarterectomy," "carotid endarterectomy surgery," "carotid endarterectomy technique," "carotid endarterectomy CEA," and "carotid artery surgery." Videos that met inclusion criteria were analyzed for surgical technique, procedural steps, surgeon specialty, video length, and date. Videos were determined to have high-quality educational content if the video included English language captions or narration and demonstrated key steps of the procedure division of the common facial vein, ideos were older than videos by cardiac surgeons (6.0 ± 1.1 y vs. 3.0 ± 0.5 y, p less then 0.05) and neurosurgeons (6.0 ± 1.1 y vs. 3.1 ± 0.8 y, p less then 0.05). CONCLUSIONS Despite more views, the field of vascular surgery is underrepresented in YouTube videos demonstrating carotid endarterectomy. Vascular surgery videos tend to be older and make up a minority of high-quality videos. As more l
