Factors associated with recurrence of varicose veins after thermal ablation: results of the recurrent veins after thermal ablation study.

Background: The goal of this retrospective cohort study (REVATA) was to determine the site, source, and contributory factors of varicose vein recurrence after radiofrequency (RF) and laser ablation.

Methods: Seven centers enrolled patients into the study over a 1-year period. All patients underwent previous thermal ablation of the great saphenous vein (GSV), small saphenous vein (SSV), or anterior accessory great saphenous vein (AAGSV).

Prognostic implications of bronchogenic carcinoma proven by bronchoscopic biopsy.

A total of 104 cases of bronchoscopically biopsy proven bronchogenic carcinoma are reviewed. Twenty-seven of 39 patients with operable lesions underwent pulmonary resection. There are seven patients with squamous cell tumors who are long-term, cancer-free survivors.
