Abstract

ResumoA intrincada anatomia tridimensional da irrigação medular é frequentemente explanada na literatura com diferentes nomenclaturas e devido a sua alta relevância no estudo da isquemia medular, o estudo da terminologia se faz necessário para melhor compreensão do tema. A artéria de Adamkiewicz, também chamada de artéria radicular magna, é a via principal. Foi realizada a revisão da literatura com equiparação das nomenclaturas utilizadas e elaboração de descrição acurada e sumarizada do conhecimento atual sobre a vascularização medular.

Highlights

Spinal blood supply was first studied by Albert Wojciech Adamkiewicz [AFI: ʔadamkiɛviʧ],1,2 a Polish pathologist, in 1881.3-6 The great radicular artery is known eponymously as the Adamkiewicz artery (AKA).[4]
A recent retrospective study using a risk model to analyze a database of results from 19 European centers with 2,235 patients registered found that 38 (1.7%) patients exhibited symptomatic spinal ischemia, providing evidence that endovascular exclusion of the intercostal arteries combined with interruption of another collateral route of spinal blood supply is a risk factor for this event
Despite the great variation in terminology found in the literature, studies are in agreement with relation to the anatomy of the spinal circulation and the existence of a large network of collateral circulation

Summary

INTRODUCTION

Spinal blood supply was first studied by Albert Wojciech Adamkiewicz [AFI: ʔadamkiɛviʧ],1,2 a Polish pathologist, in 1881.3-6 The great radicular artery is known eponymously as the Adamkiewicz artery (AKA).[4]. Knowledge of the blood supply to the spinal cord is important when planning treatment of diseases of the aorta. The vasculature involved is complex and difficult to study because of the small caliber of arteries, which make up an intricate three-dimensional network with a large degree of anatomic variation.[7] The lack of a gold standard imaging exam makes it difficult to compare existing imaging methods.[8].
