Treatment of Delayed Neurological Deficits after Surgical Repair of Thoracic Aortic Aneurysm

Abstract

Delayed neurologic deficits, paraplegia and paraparesis, are devastating complications after repair of a descending thoracic and thoracoabdominal aortic aneurysm (TAAA). A treatment protocol has not been established, although strategies such as cerebrospinal fluid (CSF) drainage, maintaining blood pressure and medication have been described. Cerebrospinal drain status /oxygen delivery/patient status (COPS) therapy for delayed neurological deficit can improve spinal cord ischemia through reducing intraspinal pressure, improving oxygen delivery and maintaining high blood pressure. We describe one patient (Case 1), in whom descending thoracic and abdominal aortic aneurysms were treated by endovascular aortic repair, and another (Case 2) with Crawford type II TAAA, who developed delayed neurological deficits that were treated with immediate COPS therapy (Modified Tarlov scale; Case1, improved from 2 to 4; Case 2, from 0 to 4). These findings indicate the benefit of COPS for treating delayed neurological deficits after descending thoracic and TAAA.
