Case report: Spinal anesthesia for cesarean section in a parturient with Potocki-Lupski syndrome

BACKGROUND: Potocki -Lupski syndrome is an uncommon disorder caused by a micro-duplication in chromosome 17p11.2. Variable clinical manifestations bring troubles to the general and neuraxial anesthesia, including mental retardation, facial dysmorphisms, structural cardiovascular anomalies, scoliosis, and malignant hyperthermia. Until now, the anesthesia management for cesarean section in these patients has not been reported yet. CASE PRESENTATION: Here we present a 23-year-old Chinese parturient with Potocki -Lupski syndrome who underwent elective cesarean section under spinal anesthesia. She was transferred to our hospital in her 40th week of gestation. She had a history of IgA nephropathy for more than three years and was diagnosed with Potocki -Lupski syndrome (17p12p11.2 segment 3.1 Mb repeat) in the 29th week of pregnancy. Amniocentesis showed the fetus had no abnormal autosomes. Preoperative multidisciplinary consultation suggested that she should terminate the pregnancy as soon as possible. She was ASA II. Her BMI was 26.43 kg/m(2). Her airway evaluation was normal. Her spine could bend well and her spinal interspace could be touched clearly. We did the single spinal anesthesia at L2-3 interspace and gave 0.5% bupivacaine 1.7 ml. The absolute anesthesia level reached T8. The Apgar score for the newborn infant was 10 for 1st minute, 5th minute, and 10th minute. The vital signs were steady without using any vasoactive drugs. The patient had a good prognosis, and was subsequently discharged from hospital. CONCLUSION: To date, the case may be the first reported spinal anesthesia for the parturient with Potocki -Lupski syndrome. Although its manifestations are variable, the spinal anesthesia is feasible under careful and comprehensive preoperative evaluation.
