Diagnostic accuracy of CT Angiography and surgical outcome of cerebral anuerysms.
Pak J Neurological Sci Jan ;4(1):8-11.

This study evaluated accuracy of 3D-CTA for diagnosing aneurysms and assessing outcome of surgical treatment. Materials and Methods: A total of 8 patients harboring 13 aneurysms were studied. CTA revealed aneurysms concurrent with other clinical and radiological findings. Accuracy of CTA for diagnosis, and the anatomical characteristics of aneurysms (such as blebs, lobes and surrounding vascular anatomy) were compared with surgical findings. Post-op CTA was done in 4 cases. Results: CTA findings regarding aneurismal morphology and vascular anatomy were confirmed at surgery in all cases (100% diagnostic accuracy). In 7 patients, aneurysms were successfully clipped. One patient underwent carotid ligation. Aneurysm clipping was not possible in 1 case, while 1 case of carotid aneurysm failed to reveal an associated small posterior communicating artery aneurysm. Recovery was excellent in 6 patients, good in 3 patients, and 1 patient died due to chest complications. Conclusion: CTA is a simple, less invasive, rapid, and reliable first-line diagnostic modality for diagnosis and early microsurgical intervention. It also avoids the complications associated with DSA. CTA may be the only angiographic modality to conclusively determine aneurysm occlusion in cases of carotid ligation.
