Gender, racial and ethnic disparities in index hospitalization operations for symptomatic carotid stenosis in Texas hospitals.

Background: Recent literature and societal recommendations support early revascularization of symptomatic carotid patients over the traditional six-week period. Nonetheless, the timing of these interventions can vary widely among populations. The goal of this study is to identify any factors influencing carotid revascularization during the index hospitalization for patients with symptomatic disease.

Reliability of preoperative venous mapping ultrasonography in predicting for autogenous arteriovenous fistula maturation.

Background: Autogenous arteriovenous fistula creation is the preferred route for vascular access for hemodialysis. Although preoperative venous mapping ultrasonography has been advocated as an operative planning adjunct and recently incorporated into the Society for Vascular Surgery clinical guidelines, controversy remains regarding its usefulness for predicting access success. The purpose of the present retrospective clinical study was to test the hypothesis that vein size measured on routine preoperative venous mapping is a poor predictor of primary fistula maturation.
