Purpose: The care of varicose vein is removal or ablation of pathologic vessels. It can be achieved by removing surgically or obliterating with sclerotherapy. The sclerosing agents first used, however, were too strong to use as a practical protocol for such veins. After the introduction of less toxic sclerosing agents, now it is a safe, easy, and reliable treatment for varicose veins. We have tried the clinical research with sclerotherapy only patients, to identify the clinical indication of sclerotherapy for primary varicose vein.
Method: We reviewed 1,583 patients with primary varicose vein who were treated with sclerotherapy at Dept of Surg, Kangbuk Samsung Hosp, SungKyunKwan University College of Medicine, from January 1996 to December 2007.
Result: The distribution of age were the first 4th decade (40.2%) followed by 5th decade, 3rd decade, the ratio of sex were more prevalent in female than male (1：9)
Sx & sign were showed cosmetic problem (60.5%) in most patients, followed by pain (18.8%), swelling (18.1%), heaviness. The duration of illness were over 5 yrs in most patients. The associating facto were correlated with pregnancy in most female (33.7%), and family History (7%), long standing posture, DM, HTN, Trauma. The size of varicose vein were type II in case 1066 (67.4%) followed by type III (27.4%), type I (4%), type IV (1%) according to the classification by Dr. Weiss. The frequency of injection were 2∼4 times (70.2%) in most patients. During 4 months of injection therapy, almost varicose veins were disappeared. Complication after injection were Hyperpigmentation 38 cases, followed by skin necrosis 16 cases in 25 cellulitis in 8 cases. Recurrence rate after injection were extremely rare.
Conclusion: The sclerotherapy of telangiectasia (Type I, II) is highly effective. Sclerotherapy based on knowledge of venous anatomy, selection of sclerosing agents, is successful treatment of varicose vein. (J Korean Soc Phlebol 2009; 8:5-8)
