A prospective evaluation of the outcome after small saphenous varicose vein surgery with one-year follow-up.

Objective: The aim was to examine the effect of various surgical maneuvers during standard surgery for small saphenous varicose veins (SSV).

Methods: This was a prospective cohort study of patients that underwent small saphenous varicose vein surgery. Two-hundred nineteen consecutive patients (234 legs) with isolated primary or recurrent small saphenous varicose veins undergoing surgery were enrolled in a multicenter study involving nine vascular centers in the United Kingdom.

National Audit of Thrombolysis for Acute Leg Ischemia (NATALI): clinical factors associated with early outcome.

Objective: The National Audit of Thrombolysis for Acute Leg Ischemia (NATALI) database is a consecutive series of patients who underwent intra-arterial thrombolysis to treat acute leg ischemia in one of 11 centers in the United Kingdom. The purpose of the study was to analyze the factors associated with outcome after 30 days.

Methods: The data were collected over 10 years on standard pro formas, and registration was completed at the end of 1999.
