In vitro fertilization outcomes in VACTERL association (vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies and limb anomalies): report of 2 cases

Objective: To report 2 cases of women with vertebral defects, anal atresia, cardiac defects, tracheaesophageal fistula, renal anomalies, and/or limb anomalies (VACTERL association) and the outcomes of their in vitro fertilization (IVF) cycles. Design: A case report. We obtained informed consent from both the patients for this case report. Setting: Outpatient clinic at an academic hospital. Patient(s): Patient 1 was a 23-year-old woman with scoliosis, tethered spinal cord, tracheaesophageal fistula, duodenal atresia, and a common cloaca at birth. Patient 2 was a 36-year-old woman with dextrocardia, congenital heart disease, scoliosis, and an imperforate anus at birth. Intervention(s): Both the patients underwent IVF. Main Outcome Measure(s): Oocyte yield, oocyte quality, and number of embryos. Result(s): Patient 1 underwent 1 IVF cycle, with 16 oocytes retrieved, of which 6 were mature. However, during intracytoplasmic sperm injection, the oocytes were noted to be extremely fragile and degenerated immediately after sperm injection. No oocyte was fertilized. Patient 2 underwent 3 IVF cycles, and 2 oocyte retrievals, with a total of 7 oocytes under cryopreservation. Conclusion(s): Both the patients’ cases presented challenges due to aberrations in pelvic anatomy and poor IVF outcomes. There is a paucity of data regarding fertility outcomes and, specifically, oocyte quality in patients with vertebral defects, anal atresia, cardiac defects, tracheaesophageal fistula, renal anomalies, and/or limb anomalies association. Their care requires a multidisciplinary assessment, an individualized approach, and continued investigation of their IVF and fertility outcomes.
