The main benign uterine pathologies suitable for interventional treatment are uterine fibroids, adenomyosis, functional uterine bleeding, and postpartum hemorrhage. The advantages of interventional treatment are the elimination or control of the tumor, good control of the corresponding symptoms, especially bleeding, and preservation of the uterus and its normal function. Not all uterine fibroids require interventional treatment. The main clinical indications are: uterine fibroids causing significant symptoms, such as prolonged and heavy periods, dysmenorrhea, rectal and bladder compression, significant abdominal masses, infertility or miscarriage, and significant psychological symptoms after the discovery of the tumor. Uterine adenomyomatosis, functional uterine hemorrhage and postpartum hemorrhage all have bleeding as the main symptom, and the purpose of interventional treatment is to stop bleeding. In general, 3F or 5F catheter and ultra-slip guidewire can be used to achieve the purpose, and microcatheter can be used if necessary. The opening of the uterine artery is highly variable, so internal iliac artery angiography can be used first to understand its starting point. Because of its forward opening, there is an overlap in the orthogonal projection, and the oblique position is more favorable to show. The amount of pinyamycin should be 4-8 mg, and the amount of iodine oil should not exceed 16 mg if the tumor is large. The dosage of iodine oil should be 4-10ml, depending on the size of the tumor. Pingyangmycin is dissolved with water-soluble iodine contrast agent and the ratio of iodine oil is 0.5-1:1. When releasing embolic agent, it must be injected slowly under fluoroscopic surveillance to prevent paralleling or refluxing misembolism. 4.The control of the degree of embolization is very important. When using PLE, it is appropriate to stain most of the uterine body, and it is usually not necessary to add gelatin sponge. If there is still a large amount of vaginal bleeding during the treatment, the addition of a small amount of gelatin sponge has the effect of immediate hemostasis. If PVA is used, it is appropriate to embolize the spiral artery of the uterus without staining, and it is not necessary to make the trunk completely embolized. 5.The embolization agent and embolization method of uterine adenomyomatosis and functional uterine bleeding are the same as those of uterine fibroids, while postpartum hemorrhage can be treated with gelatin sponge embolization first.
