Evaluation of Postoperative Status after Clipping Surgery in Patients with Cerebral Aneurysm on 3-Dimensional-CT Angiography with Elimination of Clips

Abstract

3D-CTA with elimination of bone and clips can improve the accuracy of detection of remnant necks after clipping surgery for cerebral aneurysms.

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

“…Tomura, [13] 2009 Japan 39 43 32 and 64 C 13 P = Prospective; R = Retrospective; C = Consecutive; NR = Not reported, QUADAS score = The quality assessment of diagnostic accuracy studies score …”

“…All the time, both computed tomographic angiography (CTA) and digital subtraction angiography (DSA) are deemed as valuable tools to detect cerebral aneurysms, whereas the residual or recurrent aneurysms after clipping is mainly evaluated by the use of DSA. [14] As DSA is invasive as well as time and money consuming, an increasing number of articles have reported CTA as a noninvasive screening method for the postoperative assessment of clipped aneurysms, [4][5][6][7][8][9][10][11][12][13] and with recent technological developments, some authors believe that CTA can even replace DSA for routine postoperative assessment of clipped aneurysms.

“…[4][5][6][7][8][9][10][11][12][13] Therefore, detection of the residual or recurrent aneurysms after clipping is clinically significant. All the time, both computed tomographic angiography (CTA) and digital subtraction angiography (DSA) are deemed as valuable tools to detect cerebral aneurysms, whereas the residual or recurrent aneurysms after clipping is mainly evaluated by the use of DSA.…”

The Diagnostic Value of CT Angiography in the Diagnosis of Residual Aneurysm After Brain Aneurysm Surgery

“…Residual aneurysm rate varied from 5.7% to 18% in previous articles (8). Previously it seemed that small neck remnants were not important, but it has been shown that these small neck remnants grow again and become dangerous in long term (7).…”

“…Incomplete aneurysm clipping leads to re-bleeding with fatal complications (6,7). Residual aneurysm rate varied from 5.7% to 18% in previous articles (8).…”
