To analyze the ultrasonic features of gynecological emergency and severe cases.

To analyze 431 cases in clinical, ultrasonic images and examination data of gynecological emergency and severe patients in Peking University Third Hospital from September 2014 to September 2015, and to study clinical pathological and ultrasonic imaging examination.

In 431 severe cases of gynecologic emergency, the clinical symptom were shown as acute abdominal pain or and vaginal bleeding. They were divided into seven types by clinical examination, operation or conservative treatment under dynamic observation. There were 137 cases of fracture disease, accounting for 31.8%, with corpus luteum rupture in 67 cases, ectopic pregnancy burst in 59 cases and tumor rupture in 11 cases.

There are corresponding typical ultrasonographic characteristics in different diseases of emergency and severe gynaecologic cases, combined with clinical symptoms and medical history. The right diagnosis can be made. Therefore, there are important clinical values of ultrasound in the treatment of emergency and severe gynecologic cases.
