Abstract

Background and purpose

New angiographic devices with flat panel detectors allow cross-sectional imaging within the angiographic suite. In patients receiving external ventricular drainage (EVD) to manage hydrocephalus following subarachnoid haemorrhage (SAH), these may help evaluating the position of an EVD without moving the patient to a conventional computed tomography (CT) scanner. It could facilitate patients’ management in a life-threatening status. This study therefore compares conventional CT with post-inter-ventional flat panel detector angiographic CT (FDCT) referring to the determinability of an accurate EVD position.

Material and methods

Twenty patients with SAH received FDCT and conventional CT for primary assessment after EVD insertion. Three single-blinded raters compared both modalities and evaluated the image sufficiency for determining the EVD position, EVD tip, intracranial course and whether a contorted drainage tube could be detected.

Results

FDCT was sufficient to detect a correct EVD position in 82.5% of the cases vs. 100% in conventional CT. Regarding the EVD tip, FDCT delivered at least ‘good’ results in 82.5% vs. 95% in conventional CT data. Determining the EVD intracranial course, FDCT provided at least ‘good’ data in 92.5% vs. 100% in conventional CT. For detecting tube contortion, FDCT provided at least ‘good’ results in 70% vs. 98% in conventional CT.

Conclusions

FDCT is a promising method to determine the correct position of an EVD in patients with SAH. Following a neuroradiological intervention, it facilitates the patients’ management and renders additional transfers to conventional CT unnecessary in the majority of cases.
