Epidural cooling for spinal cord protection during thoracoabdominal aortic aneurysm repair (a case study)

Abstract

Aneurysms result from damage to artery walls as a result of underlying athrosclerotic and/or thromboembolic disorders. A thoracoabdominal aortic aneurysm involves vessel damage and wall weakening in the thoracic and abdominal segments of the aorta. Thoracoabdominal aortic aneurysm repair is considered to be high risk due to the nature of the intervention that requires an extensive incision with clamping of the thoracic aorta above the renal arteries. Clamping of the aorta renders all areas distal to the clamp at high risk for ischemic trauma especially to the spinal cord where the risk of neurological deficits postoperatively is 7-16% (Cambria, et al., 1997; Davison, et al., 1997). Several adjunct interventions have been tried to reduce the risk of spinal cord injury associated with the ischemia of cross clamping. Epidural cooling has been successful as an adjunct in reducing the neurological deficits. A preoperative nursing assessment indicating the appropriate nursing diagnoses and nursing care required for this patient, allowed for individualization of the plan needed to include this new procedure and plan for best patient outcomes and practices.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
