The age, sex, duration of symptoms before surgery, and surgical finds, were all evaluated. In addition, postoperative results were also analyzed. RESULTS: Twenty-five patients were women and 11 were men. The average age of the patients was 48 years. The average time of postoperative follow-up after the surgery was 36 months. Relief from pain until now occurred in 32 patients (88%). Pain recurrence was observed in 4 patients; of those, 2 cases showed a vein compression.
