Study on foam sclerotherapy for varicose veins of lower extremities / 临床外科杂志

ABSTRACT

Objective To explore the relationship between recurrence rate and side effects of the treatment of varicose veins in lower extremity with lauromacrogol foam sclerosing agent.Methods The data of 62 patients(98 limbs)with varicose veins was collected,including 27 males (41 limbs)and 35 females (57 limbs).They were treated with 1％ lauromacrogol foam sclerosing agent combined with great saphenous vein high ligation and endovenous laser treatment.Statistical indicators included side effects such as pain,induration,hyperpigmentation,swelling,numbness and the recurrence rate.Results Two patients were lost,57 patients were injected once,further foam sclerotherapy was carried out again for 3 patients.Obvious abnormal varicose veins as well as the soreness and fatigue of lower extremity disappeared in all patients.Thirty-seven patients had pain and 43 patients developed superficial venous thrombotic sclerosis,among which 50 patients faded away after 1 to 3 months by taking diosmin.Thirty-one cases of pigmentation occurred and 20 disappeared after 1 to 3 months by applying the vitamin E whitening essence.Six patients with lower extremity ulcers recovered after 1 to 3 months.Through statistics analysis of the patients in 1-month follow-up,we found that the differences in recurrence rate after 6 months were statistically significant between group with pain induration reaction and group without (P ＜ 0.05).Among the patients without using the vitamin E whitening essence,there was a significant correlation between the duration of pigmentation and recurrence rate after 6 months.Conclusion In the process of foam sclerotherapy,the more pain induration reaction they had and the longer the duration of pigmentation sustained,the lower the recurrence rate would be accordingly.
