Most of the postpartum thrombosis occurs 7-12 days after delivery, mainly manifesting as lower limb thrombosis, swelling, pain, and changes in lower limb skin temperature, as well as changes in skin color. Postpartum thrombosis occurs mainly due to the reduction of activity after delivery, and postpartum thrombosis occurs due to mechanical damage to blood vessels, and postpartum thrombosis can also occur without good dietary management. Therefore, in case of postpartum thrombosis, treatment must be given in time, but in case of cesarean section, thrombolysis is not allowed within 17 days, and thrombolysis is recommended after 17 days, otherwise it may cause massive bleeding and oozing of blood from the incision. In patients with postpartum thrombosis, the symptoms will be significantly reduced after about 2-3 weeks of treatment.
