Intracranial Aneurysms: Clinical Value of 3D Digital Subtraction Angiography in the Therapeutic Decision and Endovascular Treatment

Abstract

Three-dimensional DSA is valuable for evaluating the potential for EVT, finding a working view, and performing accurate measurements.

Patient-Specific Computational Hemodynamics of Intracranial Aneurysms from 3D Rotational Angiography and CT Angiography: An In Vivo Reproducibility Study

“…[10][11][12][13][14][15][16] Vascular models can be constructed through segmentation of 3DRA and CTA images. Compared with CTA, 3DRA produces images with higher contrast, higher spatial resolution, and lower visibility of bone, [17][18][19] which lead to better segmentation results 20 and superior anatomic accuracy. [21][22][23] However, acquisition of 3DRA images involves the introduction of a catheter into the cerebral vasculature to locally inject contrast agent, making it more invasive than CTA, in which contrast is injected in a peripheral vein.…”

Diagnostic Accuracy of CT Angiography with Matched Mask Bone Elimination for Detection of Intracranial Aneurysms: Comparison with Digital Subtraction Angiography and 3D Rotational Angiography

“…Extension of DSA with 3D rotational angiography (3DRA) can further improve detection of intracranial aneurysms that may be obscured by overprojecting vessels. [23][24][25] The advantages of DSA over CTA are superior spatial and contrast resolution, no interference of bony structures, and the possibility to perform direct endovascular interventions. 26,27 However, DSA is an invasive technique with a small but significant risk of neurologic complications, estimated to occur in 0.3%-1.8% of patients.…”

Traumatic Carotid-Cavernous Fistula Identified by Three-dimensional Digital Subtraction Angiography-Technical Note-

“…3D-DSA is valuable for the clinical assessment of intracranial aneurysm and arterial stenosis, but the usefulness for CCFs is not known. 1,10,13) In this case, the traumatic CCF was evaluated by conventional DSA with the addition of images enhanced by 3D surface and endoscopic volume rendering using a workstation. The 3D virtual endoscopic images could depict the fistula directly.…”
