Most of the tortuous superficial veins cannot be fully recovered after delivery, so it is recommended to do a good job of prevention and health care during pregnancy. Many pregnant women do not pay attention during pregnancy, and varicose veins of lower limbs become serious after delivery. Due to the increase of pelvic pressure during pregnancy, which compresses pelvic and inferior vena cava and leads to the obstruction of venous reflux in lower limbs, it can cause partial aggravation of varicose veins of lower limbs. After maternal delivery, pelvic pressure is reduced and edema can be reduced, but tortuous varicose veins often cannot be completely relieved and restored. It is generally recommended that pregnant women who have varicose veins should wear varicose elastic stockings to avoid the occurrence of varicose veins in the later stages and to promote venous reflux and relieve maternal edema.
