title: [Spinal cord ischemia in the postoperative period of aortic surgery].
abstract: Paraplegia is a fearful and not uncommon complication of aortic clamping in surgical procedures involving thoracic and abdominal aorta. We report a case of transient spinal cord ischemia during the early postoperative period of aortobifemoral bypass in a 69-year-old male with arteriosclerosis obliterans, hypertension, type II diabetes mellitus and COLD. The anesthetic procedure was combined (peridural + intubation and mechanical ventilation + isofluorane). Two hypotensive episodes of about 80 mmHg developed, one after induction and another in the Reanimation area. The first one had a short duration, whereas the second one required the administration of colloids, crystalloids and blood. The infrarenal aortic clamping time was 35 minutes. In the early postoperative period the patient had clinical features consistent with spinal ischemia, which progressively recovered. To prevent spinal ischemia during surgery a shorter duration than 30 minutes of aortic clamping, a higher distal perfusion pressures higher than 60 mmHg during clamping, and the attempt to exclude the least possible number of intercostal and/or lumbar vessels are recommended. Drugs (corticosteroids, naloxone) and hypothermia can be useful.
