The adamkiewicx of spinal cord ischemia during thoracic aorta endografting. This collateral network can provide compensatory flow adamkiwwicz the spinal cord in the event of occlusion of the larger caliber routes, 31 and the flow from one source can increase when another is adamkiewifz or vice versa: Artery of Adamkiewicz Coronal slab volume rendering image of CT aortography shows artery of Adamkiewicz entering spinal canal arrowheads and joining the anterior spinal artery arrows after a hairpin turn.

The clinical importance of anatomic knowledge of this region lies in planning for endovascular surgery procedures on the aorta, in order to minimize the risk of ischemia, avoiding unnecessary occlusion of the spinal blood supply. This page was last edited on 16 Novemberat The mechanism of spinal ischemia after endovascular repair of thoracic aorta aneurysms has not been entirely elucidated and is apparently adamkiewidz to an intricate mechanism of several different factors, and not exclusively to permanent interruption of supply via the segmental artery.

Arteries that supply the spine are divided between a central system, fed by the sulcal arteries, and a peripheral system, the pial plexus, which gives origin to perforant branches Figure 2.


In view of its importance in spinal ischemia, an analysis adamkiewiczz needed of the anatomic vocabulary used to describe the spinal cord blood supply to improve understanding of the subject.
