Rupture of ectopic pregnancy with minimally detectable beta-human chorionic gonadotropin levels: a report of 2 cases.

BACKGROUND

Several studies have demonstrated that 25-77% of ectopic pregnancies spontaneously resolve with expectant management. However, expectant management is controversial and should be considered only for patients with small, unruptured gestational sacs, low beta-human chorionic gonadotropin (beta-hCG) levels and absence of symptoms. There is no consensus on how long to follow such patients.

CASES: Two patients with beta-hCG levels < 10 mIU/mL presented with ruptured ectopic pregnancy and hemoperitoneum.

CONCLUSION

While expectant management of a suspected ectopic pregnancy may allow spontaneous resolution of such an ectopic pregnancy, rupture may occur at any time and even with extremely low beta-hCG levels. Patients need to be counseled about the risks of rupture and symptoms, immediate action should be taken if symptoms develop, and serum beta-hCG levels should be followed to zero.
