The uterine artery embolization has been used in the treatment of uterine fibroids in our hospital for nearly 8 years. Recently, a patient with a fibroid of nearly 8 cm in size was admitted for interventional treatment, and one month after the procedure, the fibroid was necrotic and fell off vaginally. Intraoperative angiography: left uterine artery angiography showed that the left uterine artery was the main blood supply artery for the myoma. Right uterine artery angiogram. One month after discharge, he complained of flesh-like tissue visible in the vagina, and was instructed to return to the hospital to remove the necrotic tumor tissue transvaginally. At the same time, ultrasound and routine blood tests were repeated, and the anemia was significantly corrected, with a hematocrit of 88g/L without transfusion therapy. The necrotic myoma tissue was removed transvaginally. Pre-treatment ultrasonography. The ultrasonography was reviewed after the removal of necrotic fibroids after treatment. Uterine fibroids are the most common benign tumors of female reproductive system. The average age of patients is about 30~50 years old, and they often manifest clinically as menstrual changes, abdominal mass and occupying pressure symptoms such as difficulty in urination, urinary frequency and urgency, and constipation, which bring heavy physical and psychological burdens to patients. Previously, the treatment methods of uterine tumor mainly include two types of medication and surgical treatment. Uterine artery embolization (UAE) was first used in 1970, and was initially applied to stop postpartum hemorrhage, de-vascularize tumors and treat vascular malformations with good efficacy. 1993, French medical scientist Ravina first started to study the therapeutic effect of UAE on uterine fibroids. In 1994 UAE was first introduced into the treatment of uterine fibroids as an adjunct to surgical treatment of uterine fibroids for the purpose of myoma de-vascularization and reduction of intraoperative bleeding, only to find unexpectedly that the fibroids shrank significantly after UAE treatment, causing widespread interest among medical doctors from various countries. In 1995, UAE was firstly considered as an alternative to hysterectomy for the treatment of uterine fibroids, which could reduce the excessive menstrual flow caused by fibroids, relieve the symptoms of anemia, reduce the size of the uterus and fibroids, and achieve the purpose of replacing surgery. 1997 and 1998, the Ravina group reported a larger number of cases of patients with symptomatic fibroids and recurrence after myomectomy, in which uterine Arterial embolization was successful.
