Digital angiography with background erasure is a combination of conventional angiography techniques by Seldinger technique with image processing techniques by digitizing background erasing factor.
Uterine artery embolization is an effective method of preserving uterine integrity. Safe procedure, short hospital stay, patients recover soon after the procedure. This procedure is used to treat uterine leiomyoma, endometrioma, postpartum bleeding, uterine vascular malformation....

Medicines Antiseptic solution for skin and mucous membranes. Local anesthetics General anesthetics (if necessary) Water-soluble iodinated contrast agents; Heparin and Heparin neutralizing drugs; General medical supplies 1, 3, 5, 10ml syringes and syringes for contrast injection machines. Physiological saline; Etroley car. Surgical clothing; Sterile kit (scissors, knife, tongs, tool tray, etc.); Cotton gauze, surgical medical adhesive tape. Special medical supplies Arterial needles; Standard conductor 0.035 inch; Circuit opening set 5F - 6F; Microcatheter 1.9F – 2.7F, microwire 0.014 - 0.018 inch; Angiography Catheter 4F - 5F Y-wire Set Embolization Materials Bio-foam to help stop bleeding; Synthetic resin (PVA); Bio-adhesive (Histoacryl); Metal coils (coils) of all sizes. Patients Patients are carefully explained about the procedure to coordinate with the doctor. Need to fast, drink before 6 hours. Can drink no more than 50ml of water. In the intervention room: the patient lies on his back, fitted with a monitor to monitor breathing, pulse, blood pressure, electrocardiogram, SpO2. Disinfect the skin, then cover with a sterile, perforated cloth. The patient is too excited, cannot lie still, needs sedation... Test card Inpatient medical record There is an approved order to perform the procedure. X-ray, micro-tomography Computed tomography (CT), magnetic resonance imaging (CHT) (if any).

2.2 Procedures Procedure This technique is done when the patient is admitted to the hospital, the patient only needs to stay at the hospital after 1-2 days after the procedure. The patient was admitted to the hospital the day before the procedure and was thoroughly explained about the procedure for peace of mind.

The doctor and the assistant wear lead coats, lead collars, wash hands, and wear gloves. Spread sterile gauze on the patient. Anesthetize the area of ​​the common femoral artery 1cm below the inguinal fold. Skin incision, arterial puncture with a needle. Insert the lead and insert the arterial accessor into the femoral artery. Insert the catheter into the uterine artery and take a scan. When it is satisfactory, pump PVA mixed with contrast material until the tumor is completely blocked, then stop. Take a re-check. Next, thread into the contralateral uterine artery and follow the same steps as above. Remove catheter, femoral artery opener, and apply pressure to the puncture site. The patient lies motionless for about 6-8 hours, after which the compression bandage can be removed. After embolization, antibiotics should be given to the patient to avoid infection. Monitoring During the procedure: monitor pulse, blood pressure, After the procedure: Monitor pulse, blood pressure, intelligence, pain level and give painkillers. Check
Ultrasound after 3 - 6 - 12 - 24 months Magnetic resonance imaging can be done after 6 months.

3. Accidents and handling
