Brief Summary
The aim of the present study was (i) to evaluate whether a single measurement of VEGF would allow us to distinguish between intrauterine pregnancy (normal and abnormal) and EP and (ii) to correlate the levels of VEGF with serum levels of progesterone and β-hCG in each subgroup. Ninety patients were selected from a population of women presenting to the Hospital das Clínicas of the University of São Paulo Medical School from October 2006 until September 2007 and were divided in three subgroups: (i) abnormal (arrested) intrauterine pregnancy (defined as a gestational sac greater than 16 mm of mean diameter without fetal tissue or a embryo greater than 5 mm without embryo cardiac activity); (ii) tubal pregnancy (no evidence of intrauterine pregnancy, presence of a adnexal mass, suboptimal rise of serum hCG levels in 48 hours); all tubal pregnancies were surgically treated and were histologically confirmed, they did not receive any methotrexate treatment before operation; (iii) normal intrauterine pregnancy (intrauterine gestational sac, embryo vitality confirmed). Blood samples were collected by peripheral venous puncture before treatment; a total 15 mL of blood was withdrawn (2 mL for β-hCG, 3mL for progesterone, 10 mL for VEGF determinations). Blood samples for VEGF were collected in siliconized tubes and were allowed to coagulate at room temperature for 2-6 hours.

Interventions
Blood samples were collected by peripheral venous puncture before treatment; a total 15 mL of blood was withdrawn (2 mL for β-hCG, 3mL for progesterone, 10 mL for VEGF determinations). Blood samples for VEGF were collected in siliconized tubes and were allowed to coagulate at room temperature for 2-6 hours.
