Ultrasonographic diagnosis of symptomatic deep venous thrombosis in pregnancy

Article Abstract:

In women under 40 years old, pregnancy increases the risk of deep vein thrombosis (clot formation). The problem may be recognized by symptoms, and venography (analysis of vein flow by X-rays and contrast materials) aids in the diagnosis, but also exposes the mother and fetus to hazards. Ultrasound imaging performed with tissue compression can diagnose over 95 percent of all cases of deep vein thrombi, but the use of this technique in pregnant women has not been well studied. The effectiveness of Doppler (ultrasound) color imaging of blood flow was evaluated in new patients with suspected deep vein thrombosis; the previous records of pregnant patients with clots were examined; and 51 nonpregnant patients (28 female) were also evaluated. In the retrospective study, clots were suspected in 22 out of 26,191 pregnancies; venography confirmed thrombosis in 11 of these patients. In the study of current patients, 28 of 10,000 patients were suspected of having thrombosis, and seven actually had clots. Of the 51 nonpregnant subjects, venograms were considered diagnostic in 45 subjects. The left side was affect in 16 of 18 pregnant subjects, and in 13 of 32 nonpregnant subjects. Ultrasonography provided similar results to venography in diagnosing deep venous thrombosis in pregnant women. Thrombosis in the iliofemoral (pelvic and upper thigh) region, rather than the lower thigh or popliteal (behind the knee) area, was more common in pregnant subjects. The study indicates that compression ultrasonography, with or without Doppler imaging, is effective in evaluating deep vein thrombosis in pregnant patients.

Sarcoma associated with pregnancy

Article Abstract:

Sarcoma, a form of cancer found in soft tissues, is rare in pregnancy. This case study involved a patient with a small benign uterine fibroid tumor diagnosed by ultrasound (the use of high frequency sound waves to visualize internal structures). In the 34th week of pregnancy, she had abdominal pain and pressure. A normal baby was delivered by cesarean section (surgical abdominal removal of the fetus), at which time the uterine mass was also removed. After laboratory analysis confirmed the malignancy, a total abdominal hysterectomy was performed. The cancer had no apparent effect on the fetus.

Assessment of uterine arterial notching as a screening test for adverse pregnancy outcome

Article Abstract:

The detection of bilateral uterine arterial notching on ultrasonographic examination of pregnant women may predict a higher risk of complications. Arterial notches are characteristic waveform patterns detected when arteries are assessed by Doppler ultrasound. Researchers looked for this pattern during prenatal diagnostic testing in 6,579 women. Fifty-seven percent of women with notches on both uterine arteries developed pregnancy complications, and 72% of women with arterial notches that persisted at 22-24 weeks gestation developed hypertension, low birth weight, or other complications.
