Color Doppler ultrasound of spiral artery blood flow in mid first trimester (4-8 weeks) in cases of threatened abortion and in normal pregnancies.

Introduction: The aim of the study was to evaluate and compare the spiral artery flow in mid first trimester (4-8 weeks) in cases of threatened abortion and in normal pregnancies.

Material And Methods: Spiral artery was sonographically evaluated in 50 patients comprising two groups of 25 women each. The first group included patients presenting with threatened miscarriage (vaginal bleeding/spotting with or without abdominal pain).

Contrast Intravasation During Hysterosalpingography.

Hysterosalpingography is an imaging method to evaluate the endometrial and uterine morphology and fallopian tube patency. Contrast intravasation implies backflow of injected contrast into the adjoining vessels mostly the veins and may be related to factors altering endometrial vascularity and permeability. Radiologists and gynaecologists should be well acquainted with the technique of hysterosalpingography, its interpretation, and intravasation of contrast agents for safer procedure and to minimize the associated complications.
