Reproductive Outcomes Following Uterine Artery Occlusion at the Time of Myomectomy: Systematic Review and Meta-analysis

This investigation sought systematically to review and meta-analyze evidence on reproductive outcomes following uterine artery occlusion (UAO) at myomectomy. Databases searched included PubMed, EMBASE, Ovid MEDLINE, Web of Science, and ClinicalTrials.gov. Eligible studies included observational and randomized controlled trials in which patients underwent abdominal, laparoscopic, or robotic myomectomy and in which at least one measure of clinical pregnancy rate, live birth rate, or ovarian reserve was reported. The primary outcome was live birth rate. Secondary outcomes included clinical pregnancy rate, miscarriage rate, adverse pregnancy outcomes, and measures of ovarian reserve. Twelve articles involving 689 women were included in the systematic review. The intervention group underwent UAO at laparoscopic or abdominal myomectomy (UAO+M) (n = 470). The control group underwent myomectomy alone (n = 219). Seven articles involving 420 women were included in the meta-analysis (201 underwent UAO+M; 219 underwent myomectomy alone). Live births occurred in 54 of 201 (27%) women in the UAO+M group and in 74 of 219 (34%) women in the control group. Clinical pregnancies occurred in 73 of 201 (36%) women in the UAO+M group and in 102 of 219 (47%) control subjects. There was no difference in live birth rates (odds ratio 0.89; 95% CI 0.56–1.43; P = 0.51; 7 studies, 420 patients) or clinical pregnancy rates (odds ratio 0.81; 95% confidence interval 0.53–1.24; P = 0.33; 7 studies, 420 patients) between the UAO+M and control groups. Data on miscarriage rates, adverse pregnancy outcomes, and measures of ovarian reserve precluded meta-analysis. In conclusion, UAO at myomectomy is not associated with reductions in live birth or clinical pregnancy rates. Before routine use can be recommended in women desiring future fertility, more research is required on reproductive outcomes and effects on ovarian reserve.
