Abstract

ObjectiveTo report the successful utilization of transmyometrial embryo transfer (TMET) in a patient with a history of radical trachelectomy. DesignVideo article. SettingAcademic fertility center. Subject(s)A 39-year-old, para 1, woman with a history of radical trachelectomy and abdominal cerclage presented with secondary infertility. Her prior pregnancy was conceived naturally. Her first in vitro fertilization (IVF) cycle yielded only one day-7 euploid blastocyst. All attempts at performing mock embryo transfers, cervical dilatation and hysteroscopy were unsuccessful due to absence of clinically identifiable cervical tissue. The euploid embryo was transferred into a gestational carrier; however, this resulted in a biochemical pregnancy. She underwent a second IVF cycle that yielded one day-5 euploid blastocyst. Given her history, TMET was planned. The patient included in this video gave consent for publication of the video and posting of the video online including social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus, etc.) and other applicable sites. InterventionTMET using the Towako® catheter. Main Outcome MeasuresImplantation, clinical pregnancy and live birth. ResultsFollowing institutional and Health Canada approval of the Towako® catheter, a transvaginal-ultrasound guided TMET was performed under sedation with intravenous midazolam and fentanyl. The day-5 euploid blastocyst from the second IVF cycle was transferred and the patient’s β-human chorionic gonadotropin (β-hCG) levels 9 and 11 days after TMET were 86 IU/L and 262 IU/L, respectively. A single intrauterine pregnancy with cardiac activity of 119 beats/min was noted at a gestational age of 7 weeks and 2 days. The patient delivered a live singleton at 35 weeks and 2 days weighing 2182 grams. ConclusionTMET is a useful clinical technique for transferring embryos in patients with acquired or congenital cervical issues in whom trans-cervical embryo transfer is either very difficult or impossible.
