Segmental epidural anesthesia for cesarean section in a parturient with uncorrected Taussig–Bing anomaly with transposition of the great arteries physiology

Here, we report a rare case of a 23-year-old term parturient with Eisenmenger syndrome due to Taussig-Bing anomaly presenting with gestational hypertension, oligohydramnios, and intrauterine growth retardation posted for elective cesarean section. Preoperatively, echocardiography of the patient was suggestive of double-outlet right ventricle (DORV) with large sub-pulmonic ventricular septal defect (VSD), right ventricular hypertrophy, bidirectional shunt and severe pulmonary artery hypertension. The surgery was successfully performed under a graded segmental epidural anesthesia with 2% lignocaine. Further contrast-enhanced computer tomography scan was done postoperatively and a diagnosis of Taussig-Bing anomaly (DORV with sub-pulmonic VSD) with transposition of the great arteries physiology was made. This is one of the rare cases of anesthetic management for cesarean section in a parturient with uncorrected Taussig-Bing anomaly being reported.
