A Clinical Analysis of 604 Cases of Varicose Veins

ABSTRACT

PURPOSE: We reviewed 604 cases of varicose veins managed in our hospital and the clinical feature and the results were analyzed between injection sclerotherapy and operative method. METHODS: Retrospective review of clinical records was done from January 1990 to June 1998. All of them were diagnosed as primary varicose veins of lower extremities. Sclerosing agents used were ethanolamine oleate, most commonly, hypertonic saline, sodium tetradecyl sulfate and sclerodex. Injections of the sclerosants were 1 to 5 times as the clinical courses. Then, elastic stocking was applied for 2 weeks. Operations were done under the spinal or general anesthesia and postoperatively remnant varicoses were managed by injection sclerotherapy. Student t-test was used in statistics. RESULTS: The distribution of age were 5th decade (36.8%), 6th decade (24.0%), 4th decade (22.2%) in order of frequency, and the mean age was 44.3 year and the male to female ratio was 14.0. The mean duration of illness was 12.6 year, and it was longer in female than male (13.2 vs. 8.7, p=0.02). The most common presumed predisposing factor was longstanding occupation (82% of all) and pregnancy was the 2nd in female (12.0%). Chief complaint was only cosmetic problem in 73% of patients and the others complained varicose induced symptoms and complications. Both lower extremities were involved in 41.9% and right leg was in 26.0%, left leg was in 32.1%. The locations of lesions were calf (41.4%), greater saphenous vein (34.6%), lesser saphenous vein (15.0%). Sclerotherapy was done in 48.0%, operation with sclerotherapy in 23.7%, operation only in 17.2%. The mean duration of illness in sclerotherapy group was significantly shorter than operation group (8.8 vs 14.7 year, p=0.0001). Operation methods were stab avulsion only (48.1%), greater saphenous vein stripping (37.3%) and perforator ligation (11.8%) and others. CONCLUSIONS: Injection sclerotherapy method is very effective and sufficient treatment modality in the management of lower extremity varicose vein with low recurrence and complication rate, especially in the early treated cases.
