Varicose veins are minimally invasive procedures that vary in terms of how they are performed and how long they take. Traditional methods include high saphenous vein ligation and stripping, which is performed under lumbar anesthesia and takes about 1.5-2 hours to operate. Minimally invasive methods include saphenous vein laser, radiofrequency, and microwave treatments, which are less invasive and have a quicker recovery, and can often be performed within an hour, under local anesthesia. For varicose veins in the lower leg, sclerotherapy can be performed, and you can get off the floor right after the surgery and be discharged the next day after the surgery. Some large medical centers perform outpatient surgery on an outpatient basis with minimal trauma and quick recovery. The specific surgical method to be used will depend on the lesion or the degree of varicosity to choose the appropriate treatment.
