Review of Thoracic Endovascular Aneurysm Repair (TEVAR), Spinal Cord Ischemia (SCI), Cerebrospinal Fluid (CSF) Drainage and Blood Pressure (BP) Augmentation
نویسنده
چکیده
The object of this review is to examine the role of TEVAR in causing SCI. The anatomy and physiology of blood flow to the spinal cord is examined. The role of auto regulation of blood flow within the spinal cord is also examined. This review examines the reported results from the scientific literature of the effect of thoracic aortic aneurysm repair on spinal cord blood flow. In the light of these findings several conclusions can reasonably be reached. These conclusions are that the development of SCI can reasonably be predicted based on complexity and extent of the TEVAR procedure performed and BP augmentation and CSF drainage can significantly reduce the impact of SCI.

A systematic review of spinal cord injury and cerebrospinal fluid drainage after thoracic aortic endografting.
BACKGROUND The use of thoracic endovascular aneurysm repair (TEVAR) is increasing. Similar to open repair, TEVAR carries a risk of spinal cord ischemia (SCI). We undertook a systematic review to determine whether preoperative cerebrospinal fluid (CSF) drainage reduces SCI. METHODS PubMed, the Cochrane Library, and conference abstracts were searched using the keywords thoracic endovascular aor...

Thoracic endovascular aortic repair (TEVAR) has shown lower mortality compared with open surgical repair (OSR). However, the risk of spinal cord ischaemia (SCI) remains similar than OSR. As a prophylactic measure to reduce the risk of SCI, cerebrospinal fluid (CSF) drainage has been widely used in OSR. In TEVAR, the utility of this adjunct is still controversial. We report a case of a 56-year-o...

The endovascular repair of thoracic aorta (TEVAR) has significantly decreased the overall incidence of neurologic complications when compared with open surgery. Nevertheless, the risk of paraplegia remains an important concern, with rates ranging from 2% up to 8% (1). Risk factors for spinal cord ischemia following TEVAR include prior abdominal aortic aneurysm (AAA) repair, prolonged hypotensio...
