The Hospital Privileges Practice Guideline Writing Group of the Society for Vascular Surgery is making the following five recommendations concerning guidelines for hospital privileges for vascular surgery and endovascular therapy. Advanced endovascular procedures are currently entrenched in the everyday practice of specialized vascular interventionalists, including vascular surgeons, but open vascular surgery remains uniquely essential to the specialty. First, we endorse the Residency Review Committee for Surgery recommendations regarding open and endovascular cases during vascular residency and fellowship training. Second, applicants for new hospital privileges wishing to perform vascular surgery should have completed an Accreditation Council for Graduate Medical Education-accredited vascular surgery residency or fellowship or American Osteopathic Association-accredited training program before 2020 and should obtain American Board of Surgery certification in vascular surgery or American Osteopathic Association certification within 7 years of completion of their training. Third, we recommend that applicants for renewal of hospital privileges in vascular surgery include physicians who are board certified in vascular surgery, general surgery, or cardiothoracic surgery. These physicians with an established practice in vascular surgery should participate in Maintenance of Certification programs as established by the American Board of Surgery and maintain their respective board certification. Fourth, we provide recommendations concerning guidelines for endovascular procedures for vascular surgeons and other vascular interventionalists who are applying for new or renewed hospital privileges. All physicians performing open or endovascular procedures should track outcomes using nationally validated registries, ideally by the Vascular Quality Initiative. Fifth, we endorse the Intersocietal Accreditation Commission recommendations for noninvasive vascular laboratory interpretations and examinations to become a Registered Physician in Vascular Interpretation, which is included in the requirements for board eligibility in vascular surgery, but recommend that only physicians with demonstrated clinical experience in the diagnosis and management of vascular disease be allowed to interpret these studies.

BACKGROUND: Neurogenic thoracic outlet syndrome (NTOS) results from compression of the brachial plexus by the clavicle, first rib, and scalene muscles and may develop secondary to repetitive motion of the upper extremity. Athletes routinely perform repetitive motions, and sports requiring significant arm and shoulder use may put the participant at increased risk for NTOS. Competitive athletes who develop NTOS may require first rib resection and scalenectomy (FRRS) for symptomatic relief. However, the effectiveness of FRRS has not previously been studied in this vulnerable population. METHODS: This is a cross-sectional study of competitive athletes with NTOS who received FRRS by the senior author between 2009 and 2014. Eligible patients were contacted by phone and invited to complete a nine-item survey assessing the long-term effects of FRRS on pain medication use, postoperative physical therapy duration, patient satisfaction, symptom relief, activities of daily living, athletic performance, time to return of athletic performance, and need for other operations. Multivariate analyses of the following risk factors were performed: age, pectoralis minor release, preoperative narcotic use, athletic shutdown, and involvement in a throwing sport. RESULTS: There were 232 competitive athletes who met the inclusion criteria, and 67 of these (age, 14-48 years; 35 male; 99% white) responded to the survey. The average time between surgery and survey completion was 3.9 years (range, 2.2-7.0 years). The most frequent sports conducted by this group were baseball and softball (n = 44 [66%]), volleyball (n = 7 [10%]), and cheerleading and gymnastics (n = 5 [7%]), ranging from high-school to professional levels. The survey results revealed that 96% were improved in pain medication use, 75% would undergo FRRS on the contralateral side if needed, 82% had resolution of symptoms, and 94% were able to perform activities of daily living without limitation; 70% returned to the same or better level of athletic activity after FRRS, and this occurred within 1 year in 50%. Multivariate regression analysis identified younger age as a predictor of the length of physical therapy and preoperative narcotics use as a predictor of symptom resolution. CONCLUSIONS: At our center, >40% of patients requiring FRRS for NTOS are competitive athletes. The results of this study show that the majority of them are able to return to their precompetitive state after FRRS, and few experience limitations in their daily living activities. Half can return to competition at or exceeding their premorbid ability level within 6 months of surgery. The majority are pleased with their decision to undergo FRRS. Further investigation is needed to identify predictive factors for successful return to competitive athletics.

A 63-year-old female patient presented with transient right hand weakness and left amaurosis fugax. A computed tomography angiogram demonstrated a 75% to 90% internal carotid artery (ICA) stenosis and a persistent proatlantal intersegmental artery (PAIA) originating from the external carotid artery (ECA), passing lateral to the internal jugular vein (A), and joining the ipsilateral vertebral artery. The PAIA was the major contributor to the basilar artery. Also noted were an absent left cervical vertebral artery and a hypoplastic right vertebral artery terminating as the posterior inferior cerebellar artery.

BACKGROUND: Hostile anatomic characteristics in patients undergoing endovascular abdominal aortic aneurysm repair (EVAR) and the placement of endografts not in concordance with the specific device anatomic guidelines (or instructions for use [IFU]) have shown decreased technical success of the procedure. But these factors have never been evaluated in regard to patient postoperative survival. We sought to assess the association between survival and (1) aneurysm anatomy and characteristics and (2) implantation in compliance with manufacturer’s anatomic IFU guidelines in patients undergoing endovascular aortic aneurysm repair. METHODS: The cohort included 273 consecutive patients who underwent EVAR at Baylor Heart and Vascular Hospital between January 1, 2002 and December 31, 2009 and had their preoperative computed tomography (CT) scan digitally retrievable. The CT scans and operative notes were then reviewed, and the anatomic severity grading (ASG) score, maximum aneurysm diameter, thrombus width, patency of aortic side branch vessels, and implantation in compliance with IFU guidelines were assessed. The unadjusted association between survival (assessed until November 1, 2011) and these variables was assessed with the Kaplan-Meier method. Moreover, propensity-adjusted (for a comprehensive array of clinical and nonclinical risk factors) proportional hazard models were developed to assess the adjusted associations. RESULTS: Seven (2.56%) patients died within 30 days from EVAR, and 88 (30.04%) patients died during the study follow-up. Patient mean survival was 6.3 years. The unadjusted analysis showed a statistically significant association between survival and thrombus width (P = 0.007), ASG score (P = 0.004), and implantation in compliance with IFU guidelines (P = 0.007). However, the adjusted analysis revealed that none of the anatomic and compliance factors were significantly associated with long-term survival (ASG, P = 0.149; diameter, P = 0.836; thrombus, P = 0.639; patency, P = 0.219; and implantation compliance, P = 0.219). CONCLUSIONS: Unfavorable aneurysm morphologic characteristics and endograft implantation not in compliance with IFU guidelines did not adversely affect patient survival after EVAR in this group of patients. This implies that unfavorable anatomy, even that which would necessitate implantation of the EVAR device outside of the IFU guidelines, should not necessarily contraindicate EVAR.
