    BackgroundSplit cord malformation (SCM) is a rare anomaly characterized by a split along the midline of the cord, which divides it into 2 symmetric or nonsymmetric entities. SCM surgical indications and outcomes are still debatable, the signs and symptoms are generally nonspecific and are commonly associated with other anomalies and deficits.MethodsWe retrospectively searched the hospital database at King Abdulaziz Medical City, Riyadh, Saudi Arabia for patients with SCM between 1998 and 2018. Descriptive statistics were used to present categorical data as percentages and frequencies.ResultsA total of 25 patients were included in this series. The mean age of patients at the time of diagnosis was 4.4 years. A total of 18 patients (72%) underwent surgical correction. The mean difference between the age at diagnosis and the age at correction was 7 months. All patients underwent intraoperative neurophysiologic monitoring. Postoperative complications were minimal. Cerebrospinal fluid leakage was noted in 2 patients, transient urinary retention was noted in 1 patient, and transient unilateral leg paresis was noted in 1 patient. Most patients (n = 15, 83%), were discharged within 19 days after surgery, and 81% showed improvement postoperatively. Over the long-term follow-up, none of the patients developed new urologic or neurologic deficits.ConclusionsMost patients with SCM present during childhood. Postoperative complications after SCM corrective surgery are generally minimal, and the overall outcomes, mainly including partial or complete symptomatic improvement and/or symptom stability and hydronephrosis resolution, were favorable.Copyright © 2020 Elsevier Inc.
