Surgical site infections after lower extremity revascularization procedures involving groin incisions.

Background: We sought to evaluate the incidence, epidemiology, and factors associated with surgical site infections (SSIs) after lower extremity revascularization procedures involving groin incisions and determine outcomes based on SSI status.

Methods: This is a single-institution, retrospective cohort study of 106 patients who underwent lower extremity revascularization procedures involving femoral artery exposure through a groin incision at a tertiary referral hospital. The primary outcome was occurrence of SSI at the groin wound.

Asymptomatic 50% to 75% internal carotid artery stenosis in 288 patients: risk factors for disease progression and ipsilateral neurological symptoms.

Introduction: This study identified characteristics of patients with moderate internal carotid artery stenosis that are at increased risk for disease progression.

Methods: Patients with asymptomatic moderate internal carotid disease correlating to 50% to 75% diameter reduction were followed for 3 years. Progression to greater than 75% diameter reduction or presentation with focal neurological symptoms was documented.
