“…tube voltage, scanning time, contrast dose and flow rate, SNR etc.). According to Takase et al "To obtain sufficient arterial opacification, rapid injection (4-4.5 mL/s) and a relatively high dose of contrast material (130-150 mL) are necessary to visualize the AKA using CTA" 9 ; in the present study the injection rate was 3.5 mL/s. However, during the examination the patient is exposed to ionizing radiation (although the dose is lower than in digital subtraction angiography), and there is a risk of iodine contrast allergy, contrast-induced nephropathy or other side effects.…”

“…Hyodoh et al reported that when using MR angiography, the AKA and GARV can appear in the same phase in 46% of cases. 9 Reduced signal intensity in the second phase is characteristic of the AKA, while reduced signal intensity over the 2 dynamic phases is characteristic of the GARV. The GARV has a longer, serpentine intradural trajectory than the AKA; it is located more caudally and has a larger caliber than the AKA.…”

“…A manipulação inadvertida ocasionaria infarto medular e paralisia. Em cerca de 19% das vezes, a sua origem ocorre na primeira ou segunda artéria lombar 13 , dado que deve ser lembrado durante a manipulação e terapêutica, sempre evitando a embolização a partir da origem da artéria lombar.…”

“…Previous studies have shown that selective spinal cord angiography [5,6], multi-detector row computed tomography (CT) angiography [7][8][9][10][11], and magnetic resonance (MR) angiography [12,13] are useful for identifying the AKA and the ASA preoperatively. However, the visualization of the AKA and of the continuity between the aorta and the ASA with these techniques may not be adequate to prevent spinal cord ischemia after surgery.…”
