Chemical obliteration of varicose veins – sclerotherapy
Small varicose and spider veins on legs, reticular veins, chronic venous insufficiency.
Sclerotherapy may be performed in patients of any age, including elderly patients. Also the origin of varicose veins, e.g. post-partum varicose veins, dermatological lesion or surgery-related varicose veins is of no significance.
The procedure consists in obliteration of varicose veins using a sclerosant injected into the lumen. The sclerosant reacts with vascular endothelium leading to vessel closure and fibrosis. The procedure does not require administration of anesthetic agents.
The procedure is usually performed in order to obliterate small varicose and spider veins. Subjects are qualified for the procedure by a vascular surgeon on the basis of duplex Doppler ultrasound scans of vessel blood flows.
Hypersensitivity to the sclerosant, active inflammation in the puncture region, skin and subcutaneous tissue infections, deep vein thrombosis
After the procedure, a graduated compression (grade 1) is placed on the patient’s limb for about 1 week. Patients are ambulating immediately after the procedure and may leave the hospital on their own. They may function normally, including walking and performing other activities of everyday life Full physical fitness is regained after 2-4 weeks. Analgesics may be required in the initial period following the procedure.
Complications are very rare. Most commonly, they consist in tender nodules present around the obliterated veins and resolving within 203 weeks. Sometimes, occluded vessels are punctured to remove blood and accelerate recovery. Skin disclolorations may develop along occluded vessels; these usually resolve after several weeks. The most serious complication is deep vein thrombosis; fortunately, it is very rare.
