Introduction: The factors that modulate trophoblastic invasion into the tubal wall remain
uncertain. Moreover, it is known that the concentration of vascular endothelial growth factor …

Abstract β-HCG (human chorionic gonadotropin) values of over 2500 IU/l are associated
with higher failure rates for therapy with prostaglandin F2 alpha in tubal pregnancies. The …

Objective To explore the factors associated with trophoblastic infiltration in ampullary
pregnancy from the perspective of clinical and pathologic characteristics. Methods A single …

Background: Consecutive measurements of β-hCG levels and sonographic evaluation of
adnexae are critical for choosing the optimal management in ampullar tubal ectopic …

Objective. To evaluate trophoblastic cell proliferation and angiogenesis in tubal pregnancy
assessed by immunohistochemical study and their correlation with an average variation of β …

Objective To assess the association between ultrasound images and serum concentrations
of vascular endothelial growth factor (VEGF) in ampullary pregnancies. Design Prospective …

Objective: To evaluate the predictive value of serum βhCG levels in discrimination of intact
tubal pregnancies from ruptured tubal pregnancies. Design: Prospective cohort study …

A histopathologic study of 84 ampullary and seven isthmic tubal ectopic pregnancies was
conducted. In 52.2% of ampullary pregnancies, the gestations were found intraluminally …

OBJECTIVE: Ectopic pregnancy continues to be a leading cause of maternal morbidity and
of reduced childbearing potential among women of reproductive age. Because of tubal …

The aim of this study was to determine if postoperative monitoring of β-hCG is able to identify
persistence of trophoblastic tissue promptly in patients treated conservatively for tubal …
