Percutaneous guided puncture in the treatment of uterine fibroids

Interventional operation is the use of ultrasound, computed tomography (CT), nuclear magnetic resonance (MRI), X-ray, laparoscopy and other modern medical imaging technology to perform targeted surgery on the organs and tissues of the lesion for diagnosis and treatment. purpose. The law has now become an indispensable part of comprehensive treatment. Due to its advantages of micro-trauma, accurate positioning, safety and effectiveness, and fewer complications, it has developed rapidly in the past 20 years. Generally divided into two major categories of vascular interventional surgery and non-vascular interventional surgery. On the basis of vascular interventional surgery, the surgical methods are gradually developed and perfected, and various operations are mainly performed under the guidance of ultrasound, laparoscopy, hysteroscopy, and fetal mirror. Such as puncture, biopsy, aspiration, intubation, injection of drugs, local hyperthermia and other surgical methods. The method has the advantages of clear image, high sensitivity, no X-ray damage, simple operation, low cost and repeated operation. Due to the traumatic function of the operation and the multiple functions of the uterus, symptomatic uterine fibroids have gradually become non-surgical treatment in recent years, and new techniques of interventional surgery have opened up new avenues for the treatment of uterine fibroids. Treatment of diseases: uterine fibroids Indication Percutaneous guided puncture for uterine fibroids is applicable to: 1. Clinical and B-ultrasound confirmed uterine fibroids. 2. Various clinical symptoms caused by fibroids, including: pelvic mass compression, menorrhagia, infertility, lower abdomen pain, etc., and require retention of the uterus. 3. The fibroids have no degeneration, and exclude uterine sarcoma or other malignant tumors. Contraindications 1. A fibroid or ovarian tumor cannot be diagnosed. 2. Obviously allergic to ethanol. 3. B super suspected fibroid degeneration or sarcomatoid changes. 4. Fibroids combined with other diseases, accompanied by severe pelvic adhesions. Surgical procedure 1. Conventional B-type color Doppler ultrasound examination: exclude uterine sarcoma, record the location, size, and blood flow of the largest fibroids. 2. The instrument is ALOKA.SSD2000 color Doppler ultrasound diagnostic apparatus. The probe frequency is 3.5MHz; the ALOKASSD650 ultrasonic diagnostic instrument has a puncture probe frequency of 3.5MHz. 3. Calculate the approximate volume of the fibroid according to the ellipsoid volume formula: / 6 × Acm × Bcm × Ccm. 4. Empty the bladder, the lower abdomen pubic symphysis combined with conventional disinfection. 5. Guided by a sterile puncture probe, the 22nd puncture needle penetrates into the middle of the largest fibroid through the abdominal wall, and injects 2-10 ml of absolute ethanol according to the size of the fibroid. 6. Avoid puncture needles through the intestine and bladder, should pay attention to the puncture probe close to the palace or fibroids, guide the direction of puncture. 7. After the puncture injection, observe whether there is leakage of the drug solution.
