Midterm follow-up of quality of life following peripheral bypass surgery.

Background: Peripheral bypass surgery is an important treatment option for patients with peripheral arterial disease. Short-term results of quality of life (QoL) after peripheral bypass surgery showed an increase in QoL at 3 months. Little is known about QoL at more than 2 years of follow-up. This study was performed to analyze QoL at midterm follow-up, and overall survival after peripheral bypass surgery.

Methods: This study was part of a randomized control trial in which intermittent pneumatic compression was compared with compression stockings in the treatment of edema after bypass surgery. Patients completed a QoL questionnaire before surgery, 14 days and 3 months postoperatively, and at least 2 years after the original operation. A survival analysis was performed to calculate survival for patients who received both autologous and polytetrafluoroethylene (PTFE) bypass grafts.

Results: The original study consisted of 93 patients, and QoL midterm follow-up was achieved for 42. QoL scores at midterm follow-up were comparable to the preoperative baseline scores for both the autologous and the PTFE groups. Three-year survival rates were 75% and 54%, respectively.

Conclusion: Although peripheral bypass surgery significantly increased QoL 3 months after surgery, midterm follow-up showed a return to baseline scores. No significant difference was found in survival between patients in the autologous and PTFE groups.
