The dilemmas in the diagnosis and management of angular pregnancy

Number of embryos transferred could possibly be associated with angular pregnancy in in vitro fertilization‐embryo transfer

“…In angular pregnancy, the gestational sac remains in the uterine cavity, but it is close to the cornua of uterus and its enlargement causes an overall outward and upward displacement of the round ligament, whereas in interstitial pregnancy, the enlargement of the gestational sac has no effect on the position of the round ligament, and it only causes a local enlargement of the segment of the fallopian tube that travels inside the uterus 7 . In recent years, cases of complications due to angular pregnancy have occasionally been reported, mostly of uterine rupture 10–12 . The results of the latest and largest prospective study of angular pregnancy to date, conducted by Bollig et al., showed that 80% of angular pregnancy cases resulted in a live birth when monitored closely throughout pregnancy, breaking the previously held association between angular pregnancy and adverse pregnancy events.…”

[10][11][12] The results of the latest and largest prospective study of angular pregnancy to date, conducted by Bollig et al, showed that 80% of angular pregnancy cases resulted in a live birth when monitored closely throughout pregnancy, breaking the previously held association between angular pregnancy and adverse pregnancy events. In addition, their study also established three clear criteria for the diagnosis of angular pregnancy by 3D ultrasound which was the surrounding endometrium sign, myometrium mantle thickness less than 5 mm and the absence of the interstitial tubal line sign.…”
