Proof of concept testing of a vascular closure device for use in fetal surgery.

Objective: Prior clinical findings have demonstrated that maternal laparotomy with trans-amniotic trans-uterine suturing of the fetoscopic port site during in utero myelomeningocele repair reduces the risk of membrane rupture. However, due to laparotomy-associated morbidity, we aimed to explore the feasibility of using a vascular closure device for percutaneous trans-amniotic trans-uterine suturing.

Methods: This IRB and IACUC-exempt study utilized 2 strategies for proof-of-concept testing of using the Abbott Perclose ProStyle Device for suture placement; 1.

Fetal Teratomas: Advances in Diagnosis and Management.

Fetal teratomas, though rare, represent a significant proportion of tumors arising during fetal development. These tumors arise from pluripotent cells and can present in varying degrees of severity, ranging from incidental findings to life-threatening conditions. Prenatal imaging, via ultrasound and MRI, is necessary for diagnosis and risk assessment.

Prenatal Surgery for Open Fetal Spina Bifida in Patients with Obesity: A Review of Current Evidence and Future Directions.

Obesity rates have significantly increased globally, affecting up to 40% of women of childbearing age in the United States. While prenatal repair of open fetal spina bifida has shown improved outcomes, most fetal surgery centers exclude patients with a body mass index (BMI) ≥ 35 kg/m based on criteria from the Management of Myelomeningocele Study (MOMS) trial. This exclusion raises concerns about healthcare equity and highlights a significant knowledge gap regarding the safety and efficacy of fetal spina bifida repair in patients with obesity.

Poor Response to Gonadotropin Stimulation and Perinatal Outcomes in Fresh In Vitro Fertilization Embryo Transfer Cycles-A Retrospective Cohort Study.

The objective was to examine the association between poor ovarian response to gonadotropin stimulation for in vitro fertilization (IVF) and adverse perinatal outcomes in singleton gestations in young patients. This was a retrospective cohort study including women aged 17-39 who underwent fresh embryo transfer and delivered a singleton neonate at a single center (pre-implantation genetic testing excluded) (2007-2022). Patients were classified as one of the following categories: poor responders-daily follicle-stimulating hormone (FSH) ≥ 150 IU yielding ≤ 3 retrieved oocytes; normal responders-4-15 oocytes; and high responders with ≥16 oocytes.
