What Does the CDFI Blood Flow Signal on a Vaginal Ultrasound Examination Suggest?

Transvaginal ultrasound frequently indicates the presence of conditions like uterine fibroids by detecting CDI blood flow signals. Observation of blood flow signals during this procedure signifies blood supply to pelvic organs, notably evident in uterine fibroids or adenomyomas where B-ultrasound can detect such signals. Comprehensive consideration of symptoms, physical examination, and gynecological evaluation is crucial for diagnosing gynecological diseases.

When ovarian cysts are present, the abundant blood flow signals surrounding them can foster growth. It is advisable to conduct blood tests for tumor markers like CA125, AFP, and HE4 to exclude malignancy. During transvaginal ultrasound with CDFI revealing abundant blood flow signals, utmost attention is necessary to avoid compromising disease diagnosis and treatment.

Transvaginal ultrasound typically does not induce bleeding. It involves inserting an ultrasound probe into the vagina, offering a high diagnostic accuracy for diseases in the accessory region. This method suits women who do not need to retain urine or have thick abdominal fat, without causing vaginal bleeding. Abnormal bleeding is more prevalent in vaginitis, cervical lesions, and endometrial lesions, necessitating gynecological examination to determine the bleeding source and appropriate treatment.

Dysfunctional uterine bleeding commonly occurs during puberty and menopause, characterized by irregular menstrual cycles and varying bleeding amounts. In severe cases, bleeding can exceed normal menstrual flow, potentially causing shock, while in mild cases, it may be continuous. This stems from ovarian function instability during these periods, often leading to anovulatory bleeding. Patients may experience amenorrhea before uterine bleeding. In reproductive-age women with regular menstrual cycles followed by vaginal bleeding after a missed period, early pregnancy loss should be considered first.

In threatened miscarriages, vaginal bleeding is usually light, accompanied by minimal or no lower abdominal pain, and may present with early pregnancy symptoms. Examination may reveal a closed cervical os, uterus size corresponding to weeks since the last menstrual period, and positive blood and urine pregnancy tests. If the fetus has died or the miscarriage cause persists, bleeding may intensify with uterine cramping, and the cervical os may dilate, indicating inevitable miscarriage. Based on patient history and examination findings, diagnosing various miscarriage types is generally straightforward.
