Varicose veins are a common vascular lesion. Common varicose vein lesions include varicose veins of the lower extremities, varicose veins of the spermatic cord, varicose hemorrhoids, and varicose veins of the esophagogastric fundus. Different parts of the lesion, the surgical program is also different, and the postoperative treatment program is also slightly different. 1. Lower extremity varicose veins: minimally invasive surgery is mainly based on MNT-microscopic minimally invasive surgery, and sclerotherapy can also be categorized as minimally invasive surgery. After surgery, injection therapy is usually not required. However, in order to prevent postoperative infections and other conditions, antibiotic drugs (such as levofloxacin) can be used intravenously for a short period of time (1 to 2 days) to prevent and treat infections. 2. Varicose veins of the spermatic cord: there is a certain amount of trauma in the operation, generally need routine application of antibiotic drugs after the operation, the use of 1 to 2 days or so can be discontinued, and the need for intravenous fluids to supplement nutrients after the operation. 3. Hemorrhoidal varicose veins: minimally invasive surgery mainly includes internal hemorrhoidal ligation, internal hemorrhoidal sclerotomy, anastomosis hemorrhoidal mucosal cricothyrotomy and other ways. After the first two operations, no needles. Take the anastomosis hemorrhoidal mucosal circumcision patients, more short-term application of antibiotic drugs after surgery, to prevent trauma infection. 4. Esophagogastric fundus varices: minimally invasive surgery is based on ligation, and antibiotic drugs are generally not needed after surgery, however, intravenous nutritional therapy is needed due to fasting.
