title: Transvaginal color Doppler in the detection of external iliac vein thrombosis in pregnancy.
abstract: A case is described where transvaginal color Doppler was used to demonstrate upward external iliac vein extension of thrombus at 26 weeks' gestation. Normally, transabdominal color Doppler can visualize the iliac vessels, but in advanced pregnancy the uterus obstructs the view. This technique is useful in determining of there is a 'high' deep vein thrombosis in pregnancy, and may also prove useful in the obese patient.
