Adenomyosis is a benign lesion caused by the invasion of the endometrial basal layer into the myometrium. Clinical manifestations of adenomyosis: Excessive menstruation and progressive dysmenorrhea are the main manifestations. Dysmenorrhea is severe and manifests as persistent lower abdominal pain, lumbago, anal cramping accompanied by nausea and vomiting. It often leads to infertility or anemia. Gynecological examination of the uterus is enlarged, mostly uniformly. It is hard and has tenderness. In a few patients, there may be nodular protuberance or surface irregularity. During menstruation, the uterus may be enlarged and softer than usual, and the pressure pain may be more obvious. A few patients have pain during sexual intercourse and have acne and chloasma on the face. Dong Fangfang, Department of Gynecology, Tangshan Maternal and Child Health Hospital Uterine adenomyosis examination: the main imaging means are ultrasound, MRI, CT and so on. Treatment of adenomyosis: Hysterectomy: It will have certain effects on the patient’s endocrine function, leading to early menopause and possible complications such as osteoporosis and cardiovascular disease. Hysterectomy or localized lesion excision: incomplete treatment, high recurrence rate, or loss of fertility. Endometrial resection: ineffective in patients with moderate to severe disease. May lead to amenorrhea, sudden hemorrhage, endometrial implantation in the pelvis causing endometriosis. Causes of adenomyosis: The causes of adenomyosis are not fully understood. Most people believe that it is related to the damage caused by pregnancy and childbirth to the endometrium, in addition, inflammation or continuous high level of hormonal stimulation may also be an important cause of this disease. Pathology of adenomyosis: It can be divided into two categories: diffuse and focal. The latter is also known as uterine adenomyoma and is not easily differentiated from uterine fibroids. According to the depth of infiltration of the lesion, it can be divided into three levels: the lesion only infiltrates the superficial myometrium, the lesion infiltrates up to the middle myometrium, and the lesion infiltrates more than the middle myometrium. Uterine artery embolization procedure: 1. Pre-embolization imaging of the right uterine artery showed thickened and tortuous uterine arteries. Staining was obvious. 2, Post-embolization showed occlusion of the uterine artery. 3, Left side uterine artery pre-embolization imaging. 4, Left side after embolization. Clinical efficacy: Dysmenorrhea relief rate: 70% to 90% of the patients had significant or obvious improvement of dysmenorrhea symptoms within 1 to 3 months after the intervention. 89% of the patients had a reduction of menstrual flow after the intervention, especially for those with hemorrhagic anemia due to excessive menstruation, the amount of menstrual flow could be reduced to 20% to 80% of the preoperative amount. For patients with fertility requirements, most of them can have normal pregnancy afterward. Anemia, patients with anemia symptoms can generally recover to normal or near normal hemoglobin level after 3 months after surgery, i.e. anemia is effectively corrected. Gynecological examination: uniform enlargement and hardness of the uterus are the characteristics of this disease. Gynecological examination 1 to 6 months after the interventional therapy can find that the uterus becomes softer and smaller in size. Change of vaginal secretion: some patients with adenomyosis had excessive leukorrhea and blood before the intervention, or various vaginitis caused by repeated infections due to increased leukorrhea. They are completely cured after the intervention. Improvement of other symptoms: Improvement of sexual life quality, disappearance of facial acne and chloasma. Post-operative review: Ultrasound and MRI can be used three to six months after the procedure to understand the changes in the size and volume of the uterus and the lesion.
