Detection of Vertebral Artery Injury after Cervical Spine Trauma Using Magnetic Resonance Angiography

Abstract

Our data suggest that the incidence of VA injury in closed cervical spine trauma is significant and that FT fractures warrant flow-sensitive magnetic resonance imaging.

Correlation of C2 Fractures and Vertebral Artery Injury

“…3,8,25,33,[36][37][38] This wide variation was probably due to underdiagnosis of asymptomatic VAI. Study group selection, sensitive and specificity difference in diagnostic methods, evaluation bias could also contribute to the variation.…”

“…Since Woodring et al 38 suggested that foramen transversarium fracture may lead to VAI, several studies have documented the relationship between the foramen transversarium fracture and VAI. 9,10,14,19,24,35,36 In two studies done by Cothren et al on aggressive screening for VAI, 16% 10 -26% 9 of patients with VAI had foramen transversarium fracture.…”

Poor surgical technique in cervical plating leading to vertebral artery injury and brain stem infarction—case report

“…The proper diagnostic modality for vertebral artery injuries with ischemia is conventional angiography or magnetic resonance angiography [26,27]. However, neither method revealed the cervical screws, whereas the anatomic relationship between the screws and vertebral artery was seen clearly in 3-dimensional reconstruction images using CT; thus, the latter is considered to be more valid for evaluating instrument-related problems.…”

Pediatric Blunt Carotid Injury. Case Report.

“…Therefore, various noninvasive techniques, such as ultrasonography, MR angiography, and three-dimensional CT angiography, have been used to screen patients with a high index of clinical suspicion. 2,14,18,22) However, these noninvasive techniques are less sensitive than conventional angiography. In our case, angiography was performed to confirm the diagnosis of occlusive carotid lesions and the collateral blood supply.…”
