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. DESIGN: Case report. SETTING: Private clinic. PATIENT(S): A couple with primary infertility for whom a diagnosis of bicornuate uterus with a very open angle between horns was confirmed. INTERVENTION(S): Laparoscopy and hysteroscopy were performed before an IVF cycle in which a single embryo was replaced. MAIN OUTCOME MEASURE(S): Air bubble image immediately after ET and gestational sac location 3 weeks later. RESULT(S): 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. CONCLUSION(S): The location of the air bubble immediately after ET does not necessarily indicate the final embryo location.
