Pelvic cyst is a common gynecological disease, which is more likely to occur in women of childbearing age. Pelvic cysts are mainly caused by acute pelvic inflammatory disease that is not completely cured and long-term inflammatory stimulation that leads to serious adhesions in the surrounding pelvic tissues. Patients mainly have symptoms such as lower abdominal pain, fatigue and dysmenorrhea, and are characterized by a high recurrence rate, which seriously affects their physical and mental health. Conventional anti-infective drug treatment is ineffective, and surgery is the main method of clinical treatment for pelvic cysts. Interventional ultrasound treatment has the advantages of accurate localization, minimally invasive, little good reaction, simple and easy, and high satisfaction of patients. Most ovarian cystic masses, which are non-redundant, have a high rate of natural regression and mostly do not require treatment. However, treatment should be given to larger ovarian cysts (diameter greater than or equal to 5 cm) and ovarian chocolate cysts, because the former has a twisted tip and the latter is prone to spontaneous rupture. Because of the traumatic nature of surgery, especially in ovarian chocolate cysts due to the large number of adhesions and brittle cyst wall, rupture and damage to other organs are inevitable during surgical peeling, and the rate of reoperation is 30% to 60% for those who are prone to adhesions and retain their ovaries after surgery. Therefore, it is necessary to use treatment with less damage. Most pelvic cysts are non-redundant and have a high rate of natural regression within a certain size range, so they do not require treatment.
