Air bubble location inside the uterus after transfer: is the embryo really there?
OBJECTIVE
To demonstrate that the location of the air bubble after embryo transfer (ET) does not necessarily indicate the final embryo location.


METHODS
Case report.


METHODS
Private clinic.


METHODS
A couple with primary infertility for whom a diagnosis of bicornuate uterus with a very open angle between horns was confirmed.


METHODS
Laparoscopy and hysteroscopy were performed before an IVF cycle in which a single embryo was replaced.


METHODS
Air bubble image immediately after ET and gestational sac location 3 weeks later.


RESULTS
Immediately after a single ET, the air bubble was seen in the left uterine horn. Three weeks later, a gestational sac was seen in the right uterine horn.


CONCLUSIONS
The location of the air bubble immediately after ET does not necessarily indicate the final embryo location.
