OBJECTIVE: To determine serum levels of vascular endothelial growth factor (VEGF) and evaluate their capacity to serve as a marker for the diagnosis of ectopic pregnancy (EP). DESIGN: Prospective, case-controlled study. SETTING: A tertiary care center. PATIENT(S): Twenty women with EP, 10 women with normal intrauterine pregnancy, and 10 women with abnormal intrauterine pregnancy, all at comparable stages of gestation. INTERVENTION(S): Serum samples were obtained from all women. MAIN OUTCOME MEASURE(S): All samples were analyzed for VEGF, progesterone, and beta-hCG by specific methods. RESULT(S): Women with EP had higher serum levels of VEGF than women with normal intrauterine pregnancy and women with abnormal intrauterine pregnancy (median levels, 226.8 pg/mL, 24.4 pg/mL, and 59.4 pg/mL, respectively). With a cutoff level of 200 pg/mL, serum VEGF could distinguish intrauterine from extrauterine pregnancy with a sensitivity of 60%, specificity of 90%, and positive predictive value of 86%. CONCLUSION(S): The increased serum VEGF levels in women with EP may facilitate this challenging diagnosis and reduce maternal morbidity and mortality.
