Correlation of serum estrogen levels with uterine and carotid arteries flow in postmenopausal women on hormone replacement therapy.

Objective: To determine the pattern of blood flow in the patients compliant and non-compliant to hormone replacement therapy.

Methods: In the period of 12 months, 106 postmenopausal women were examined by the color and pulsed Doppler ultrasonography of the blood flow through uterine, common, and internal carotid arteries (Resistance Index, RI). The study was retrospective-descriptive.

Disparate blood flow patterns in parallel umbilical arteries.

Objective: To compare resistance to blood flow between two umbilical arteries at the same cord site during the second half of pregnancy.

Methods: We evaluated 80 patients with singleton pregnancies cross-sectionally at gestational ages ranging from 20-40 weeks' gestation. Resistance to blood flow was measured separately by means of systolic-diastolic ratio (S/D) for both umbilical arteries of each subject at the same site of transverse cord section.

Color and pulsed Doppler sonography, gray-scale imaging, and serum CA 125 in the assessment of adnexal disease.

Objective: To compare color and pulsed Doppler sonography with gray-scale ultrasound imaging and serum CA 125 levels in establishing accurate preoperative diagnoses of adnexal masses.

Methods: Medical records of 109 patients referred with preexisting adnexal lesions were reviewed retrospectively by comparing preoperative ultrasonic data (gray-scale imaging and color and pulsed Doppler findings) with serum CA 125 levels.

Results: Eighty-three masses were removed surgically, confirming seven malignancies and 76 benign tumors, and 26 masses were followed; 15 regressed and 11 persisted.

Placental abruption in association with advanced abdominal pregnancy. A case report.

Background: Recognition of advanced abdominal pregnancy and care of the patient afflicted with it may present formidable challenges. Aside from the difficulty of diagnosing the problem and thereby delaying necessary intervention, management can be difficult at best, even when the condition is relatively uncomplicated. When it is compounded by a life-threatening complication, such as uncontrollable hemorrhage, it challenges the skills of the most experienced obstetrician and the resources of the best-equipped facility and its personnel.

Transvaginal color and pulsed Doppler sonography of the endometrium: a possible role in reducing the number of dilatation and curettage procedures.

The objectives of the study were to establish color and pulsed Doppler sonographic characteristics of uterine vascularity in postmenopausal patients with pathologic endometrium in order to reduce the number of unnecessary diagnostic dilatation and curettage procedures. The prospective study involved 42 postmenopausal patients who were examined, prior to dilatation and curettage operation, with transvaginal color and pulsed Doppler sonography. Twenty patients had symptoms such as vaginal bleeding or clinically enlarged uterus and 22 postmenopausal women, from our screening group, were asymptomatic.

The role of color Doppler in diagnosis of endometriomas.

The aim of this study was to characterize the appearance of the vascular pattern of endometriomas in terms of color Doppler and to verify the role of Doppler flow indices in differentiating endometriomas from other pelvic masses. Twenty patients with suspected endometriosis were referred for evaluation and surgical management of adnexal masses and/or infertility problems. Before surgery, transvaginal sonography was performed using an Ultramark 9 (ATL) Ultrasound system.
