Treatment of ruptured anterior circulation aneurysm based on computerized tomography angiography: surgical results and indications for additional digital subtraction angiography

Diagnostic accuracy and inter-rater reliability of 64-multislice 3D-CTA compared to intra-arterial DSA for intracranial aneurysms

“…Some studies have even reported superior results with 3D-CTA as either their main or single diagnostic assessment tool when evaluating cerebral aneurysms. [4][5][6][7][8][9][10] The main disadvantage of conventional IADSA is a less than 1% risk of permanent neurologic deficit. 11 Intra-venous digital subtraction angiography (IVD-SA), no longer a commonly used modality to evaluate intracranial aneurysms, is less invasive when compared to IADSA but the resolution of IVDSA tends to be poor [12][13][14] and the necessary amount of contrast agent needed to load the patient is significantly higher than with intra-arterial administration.…”

The Value of Computed Tomography Angiography in Determining Treatment Allocation for Aneurysmal Subarachnoid Hemorrhage

“…When pooling results from case series (Table 3) allocating treatment in patients with SAH using CTA [5,9,10,[16][17][18][19][20], the decision for treatment was variable among these publications (51.9-91.3%). In 8.7-48.1% of the patients a conventional cerebral angiography was performed to decide on best treatment modality.…”

“…Results of case series for unruptured aneurysms [16,17,19] show that in 50-78% of the patients a treatment decision was made based on CTA alone. Similarly, when these patients with unruptured aneurysms (n = 220) are grouped, a treatment decision using CTA was possible in 65.9%.…”

Comparison of 64 Dedector Cranial CT Angiography with Intra-Arterial DSA For Detection of Intracranial Aneurysms

“…Cranial computed tomograph-angiography (CTA) has been increasingly used during the last 10-15 years for the early diagnosis of ruptured intracranial aneurysms (1)(2)(3)(4)(5)(6)(7). CTA is more dependent on the technical parameters used, than being patient-dependent.…”
