Multi‐slice computed tomography angiography in the detection of residual or recurrent cerebral aneurysms after surgical clipping

Abstract

MSCTA is a promising technique for evaluating residual or recurrent aneurysms in patients undergoing surgical treatment of aneurysm with titanium clips.

Noninvasive Imaging of Treated Cerebral Aneurysms, Part II: CT Angiographic Follow-Up of Surgically Clipped Aneurysms

“…However, by using the newest generation of scanners and modern techniques, CTA is emerging as a tool for the noninvasive evaluation of the cerebral vasculature after surgical clipping. [12][13][14][15][16] CTA Techniques for the Evaluation of Clipped Aneurysms: Efficacy A number of reports show that multidetector CTA is increasingly replacing catheter-based angiography for the preoperative diagnosis and surgical planning for patients with both ruptured and unruptured aneurysms. [17][18][19][20] CTA is a fast, reliable, accessible, and relatively inexpensive technique that can be performed on acutely ill patients with minimal or no sedation and little associated risk.…”

Diagnosing residual or recurrent cerebral aneurysms after clipping by computed tomographic angiography: Meta-analysis

“…After detailed evaluation of the remaining 14 articles, 10 articles fulfilled the inclusion criteria. Three studies were excluded because four-fold tables could not be constructed from the data, [18][19][20] and the remaining one study was not included because the authors excluded 7 patients due to poor image quality in the comparison of CTA and DSA [15] [ Figure 1]. …”

Subtraction 3D CT Angiography with the Orbital Synchronized Helical Scan Technique for the Evaluation of Postoperative Cerebral Aneurysms Treated with Cobalt-Alloy Clips

“…Several reports [5][6][7][8][9] have discussed the postclipping evaluation of cerebral aneurysms by using CTA, most in cases using titanium-alloy clips. The quality of conventional CTA was reported as acceptable in 42/49 (86%) patients with titaniumalloy clips.…”

“…4 CTA of the brain has recently been applied to assess aneurysms surgically occluded by the use of titanium-alloy clips. [5][6][7] However, the strong artifacts from cobalt-alloy clips complicated assessment of the aneurysm neck and adjacent vessels 8,9 ; it was thought that postoperative evaluation by using CTA was difficult for patients treated with cobalt-alloy clips.…”
