Ectopic pregnancy following the treatment of tubal infertility.

To evaluate the prognosis for the patient who becomes pregnant after infertility treatment, we analyzed the occurrence of ectopic pregnancy following reconstructive surgery and in vitro fertilization/embryo transfer (IVF/ET) for tubal infertility. The results of 474 microsurgical operations and the results of 2,119 stimulated IVF/ET cycles for tubal infertility in the Reproduction Unit of Ljubljana University Department of Obstetrics and Gynecology are presented. The ratio of patients who subsequently had only ectopic pregnancies to the number of operations was 12%. Ectopic pregnancies represented 28% of all pregnancies after surgery. In IVF/ET cycles for tubal infertility, ectopic pregnancy represented 2.8% of all pregnancies and 3 permiles of all transfers. There was one (0.5%) heterotopic pregnancy. The likelihood of live births (30%, one or more times) after surgery compensates the high risk for ectopic pregnancy. While the risk for ectopic pregnancy after IVF/ET is much lower than the risk after tubal surgery, it is still rather high compared with the risk in the normal population. In the cases with severe tubal lesions IVF/ET is preferable to tubal surgery. The results show the importance of considering ectopics when deciding upon treatment and in patients who become pregnant after treatment for tubal infertility.
