[Pregnancy and partum in the woman with a spinal cord lesion in chronic phase].

A 34-year-old pregnant paraplegic woman with a T12 medullary lesion in chronic phase underwent cesarean delivery in the thirty-seventh week due to pelvic-cephalic disproportion. After failure of epidural anesthesia related to technical difficulties, general anesthesia was provided. A hypertensive crisis developed during surgery but was resolved within minutes after administration of hydralazine. No further complications arose. Pregnancy in a patient with medullary lesion in chronic phase is considered high risk, requiring special care due to extraordinary changes in pathophysiology caused by the lesion in addition to changes directly related to gestation. The main complications that arise are decreased respiratory volume and arterial pressure, increased incidence of thromboembolic events, anemia, urinary tract infections, premature birth, unusual progression of delivery and autonomic hyperreflexia, which is the most serious. When a hypertensive peak develops in such patients, the anesthesiologist must first rule out autonomic hyperreflexia, which has an incidence of 85% in lesions over T7 and has also been described in patients with lower lesions.
