Hysteroscopy in Differentiating Ectopic Pregnancy from Other Nonviable Pregnancies When Serum hCG Titers Remain Below the Threshold of Ultrasound Diagnosis

ABSTRACT

Hysteroscopy was useful in managing 5 patients with a possible ectopic pregnancy but with nonrising hCG levels below the threshold for ultrasound diagnosis. Two patients had an ectopic pregnancy, 2 patients had a threatened abortion, and 1 patient had an incomplete abortion. (J GYNECOL SURG 8:165, 1992)
