Ultrasound is a method of using ultrasound waves with frequencies ranging from 1-10MHZ to examine, when the ultrasound waves pass through the internal tissues of the body, it will capture images and transfer them to the processor. Currently, ultrasound technology is very commonly used in disease diagnosis and in guiding treatment interventions.

3. Procedure for performing cyst aspiration and sclerotherapy under ultrasound guidance

3.1 Preparation Performer: 02 Specialist doctors (doctor conducting aspiration and ultrasound), nurses. Facilities: Ultrasound machine with specialized probes, image storage system. Medicines: Local anesthetic, alcohol solution used for sclerotherapy, antiseptic solution. Medical supplies: Syringe 5; 10ml; Distilled water or physiological saline; Gloves, shirt, hat, surgical mask; Aseptic intervention kit: Knife, scissors, tongs, metal bowl, bean tray, tool tray; Cotton, sterile gauze, surgical tape, sterile gasoline; Medicine box and emergency equipment for drug-induced accidents during the procedure; Specialized needle aspiration; Standard conductor. Patients: Patients are clearly explained about the procedure and possible complications so that they can cooperate with the doctor; At the intervention room: The patient lies down, has an intravenous line, installed a machine to monitor indicators such as breathing rate, pulse, electrocardiogram, blood pressure, SpO2; The skin is disinfected then covered with a sterile, perforated cloth; Patients in a state of overstimulation, anxiety, restlessness, not lying still: Need to use sedation... 3.2 Steps Step 1: Check the position of the cyst to be aspirated by ultrasound before perform aspiration. Step 2: Disinfect the needle puncture site and administer local anesthesia with anesthetic. Step 3: Carry out aspiration, insert the needle into the position of the damaged fluid capsule under the guidance of ultrasound, according to the pre-selected path, aspirate a little fluid for testing, then proceed to aspirate the maximum amount. fluid can be aspirated in the cysts. Step 4: Inject the fibrous substance into the aspirated cyst, the maximum amount of fibrous injected is equal to the amount of suctioned fluid, keeping the fibrous substance from 15 to 30 minutes in the cyst. After performing cyst aspiration and sclerotherapy under ultrasound guidance, the patient rested at bed for 6 hours, monitored pulse, blood pressure, puncture site for 24 hours.
3.3 Monitoring of complications and handling of complications In general, cyst aspiration and sclerotherapy under ultrasound guidance are quite safe procedures for patients, but also note some possible complications as follows: :
