Morbidity of varicose vein surgery: auditing the benefit of changing clinical practice.

During two consecutive study periods (24 months and 16 months), 997 patients (1322 legs) with varicose veins underwent surgical treatment in Huddersfield Royal Infirmary, using a variety of surgical techniques. The average length of stay was 1.5 days, and 95.5% of patients had a hospital stay of less than 2 days. Complications occurred in seven inpatients. A further 16 patients developed complications requiring readmission to hospital (10 minor and intermediate; 6 major). The complication rate appeared to be operator-dependent: an increased complication rate (particularly major complications) occurred after surgery by junior surgeons. Major complications included femoral vein injury (1 patient), postoperative deep venous thrombosis (4 patients), pulmonary embolism (1 patient) and groin lymphatic fistula requiring reoperation (1 patient). Between the first and second study period, a change in policy regarding the type of bandaging used and the use of postoperative antiembolic stockings occurred and appears to have reduced the incidence of thromboembolic complications from 0.7% to 0.2%. Varicose vein surgery is not without major complications though, fortunately, there was no mortality in this series. These complications can be minimised with good surgical technique and better supervision of surgical trainees. Modification of postoperative management can further enhance the safety of this procedure.
