Three-dimensional Power Doppler in the Diagnosis of Endometrial Lesions in Patients With Postmenopausal Bleeding

The Accuracy of Three-dimensional Power Doppler Ultrasound in the Diagnosis of Endometrial Lesions in Patients With Postmenopausal Bleeding Compared With the Endometrial Histopathology.

100 women suffering post-menopausal bleeding will be included in the study. All the participants will undergo 3D Transvaginal Ultrasound to assess the endometrium and myometrium (for the presence of any focal lesions e.g. polypi) followed by 3D Power Doppler ultrasound assessment of the vascular indices: vascularization index (VI), flow index (FI) and vascularization-flow index (VFI) and endometrial volumes.

The results of the ultrasound and Doppler indices will be correlated to the histopathological examination of specimens collected following fractional curettage or hysterectomy.

Study Overview

• Status: Unknown
• Conditions: Postmenopausal Bleeding
• Intervention / Treatment: Diagnostic test: 3 dimensional ultrasonography and Doppler

Detailed Description

100 women suffering post-menopausal bleeding (occurred after at least 12 months of amenorrhea) will be included in the study.

After obtaining an informed consent entailing the explanation of the study and its aim, all participants will undergo the following; full history taking (including full menstrual history and the date of menopause), complete physical examination, laboratory investigations (complete blood count, liver function tests, kidney function tests and a coagulation profile). Baseline 2D transvaginal ultrasound will be done to measure endometrial thickness and to detect presence of any endometrial and myometrial focal lesions. 3D-transvaginal ultrasonography will be done to acquire multi-planner view of the uterine cavity and detect presence or absence of any cavitary or myometrial lesions and acquire endometrial volumes. This will be followed by 3D Power Doppler Ultrasound assessment of the vascular indices namely; vascularization index (VI), flow index (FI) and vascularization-flow index (VFI).

Transvaginal sonography will be performed for all patients using Voluson 730 PRO V transvaginal volumetric probe transducer with frequency range of 5-8 MHz equipped with color, power and pulsed Doppler capabilities. First, conventional gray-scale sonography will be performed to obtain longitudinal and transverse sections of the uterus. Maximum endometrial thickness (double-layer) will be measured in the longitudinal plane with the detection of any focal lesions.

For Three-Dimensional Ultrasound: Once the B - mode had been completed, three-dimensional images will be recorded. The volumes will be generated by the automatic rotation of the mechanical transducer 360 degrees. The probe will be kept steady, the patient will be asked to hold breath and volume mode will be switched on. With the use of the medium line density, the typical acquisition time will be between 4 and 10 seconds. Visualization of the endometrium in the three planes will be done to detect endometrial cavity. Endometrial margin, echogenicity and presence of intrauterine fluid will be examined to notice the presence of any heterogenic pattern, irregularity, asymmetry in the margin or local thickening denoting the presence of polyp, endometrial hyperplasia, or carcinoma. The myometrium will be also examined in the three planes to detect any other focal lesion e.g. Fibroid or Adenomyosis.

For Power Doppler Study, the power Doppler gate will be activated for blood flow mapping of the endometrium and endometrial-myometrial interface (sub-endometrial area). Power Doppler settings will be set to achieve maximum sensitivity for detecting low velocity flow without noise. Once the vessels have been identified, the pulsed Doppler sample volume will be activated to obtain a flow velocity waveform (FVW). Vascularization index (VI), flow index (FI) and vascularization-flow index (VFI) will be automatically calculated from three consecutive FVWs. Only endometrial and endometrial-myometrial interface vessels were included.

The patient will then be admitted for either a D and C operation (Endometrial curettage) or for Total Abdominal Hysterectomy. All removed tissues will be sent for histopathological examination of the endometrium or of any pathological uterine lesion. Pathological examination results will be correlated to ultrasound (2D and 3D) and Doppler findings,
