Aspiration cyst, sclerotherapy under ultrasound guidance

This is an automatically translated article.

Aspiration of cysts and injection of scleroderma under ultrasound guidance is a simple technique and is often used in the treatment of liver cysts, large kidney cysts... Under the guidance of ultrasound, the aspiration will take place simply. and more accurate, limiting many dangerous complications for patients.

1. What is cyst aspiration and sclerotherapy?

Cyst aspiration and sclerotherapy under the guidance of ultrasound is a procedure to insert a needle directly into the cysts to drain the fluid and combine with injection of scleroderma, which helps to fibrosis and shrink the fluid-filled cysts.
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. Aspiration cyst and sclerotherapy under ultrasound guidance are simple and effective methods in the treatment of liver and kidney cysts.

2. Indications and contraindications

Indications for cyst aspiration and sclerotherapy under ultrasound guidance in the following cases:
Large cysts in the liver and kidneys with painful symptoms, affecting the patient's quality of life; Liver cysts, infected renal cysts, and chemical abscesses need to be aspirated and drained. Contraindicated cyst aspiration and sclerotherapy under ultrasound guidance in the following cases:
Absolutely: Severe coagulopathy; Prothrombin rate < 70%; Platelet count < 50 G/l; Allergy to anesthetics. Relative: Liver failure, renal failure, respiratory failure, severe circulatory failure, severe ascites, the patient did not agree to the intervention.

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: :
Pain at the puncture site: Use pain relievers; Bleeding: Monitor the aspiration site for early detection of bleeding complications. If bleeding is minimal, medical treatment, bed rest and monitoring are required. If the bleeding does not stop, surgical intervention and blood transfusion are required. The cyst ruptures and causes fluid, fibrous drugs during intra-abdominal injection: If the amount is small, the patient needs to be motionless at the bed and closely monitored, if the amount is large, it is necessary to conduct surgery to wash and aspirate to avoid causing the phenomenon. fiber-induced fibrosis and treatment of peritonitis. Hollow visceral perforation: Rare, but if it does, it needs to be treated with surgery.

Although this is a fairly safe procedure, every intervention carries a small or high risk of complications. To limit the risk of complications, patients need to perform cyst aspiration and sclerotherapy under ultrasound guidance at reputable facilities with full necessary equipment and experienced operators. Currently, Vinmec International General Hospital is one of the leading prestigious hospitals in the country, trusted by a large number of patients for medical examination and treatment.
