چکیده
BACKGROUND In order to declare the preoperative diagnostic value of brain aneurysms, two radiological modalities, computed tomographic angiography and digital subtraction angiography were compared. METHODS In this descriptive analytic study, diagnostic value of computed tomographic angiography (CTA) was compared with digital subtraction angiography (DSA). Sensitivity, specificity, positive and negative predictive values were calculated and compared between the two modalities. All data were analyzed with SPSS software, version 16. RESULTS Mean age of patients was 49.5 ± 9.13 years. 57.9 % of subjects were female. CTA showed 89% sensitivity and 100% specificity whereas DSA demonstrated 74% sensitivity and 100% specificity. Positive predictive value of both methods was 100%, but negative predictive value of CTA and DSA was 85% and 69%, respectively. CONCLUSIONS Based on our data, CTA is a valuable diagnostic modality for detection of brain aneurysm and subarachnoid hemorrhage.

Diagnostic Accuracy of Computed Tomographic Angiography (CTA) in the Management of Aneurysmal Subarachnoid Haemorrhage (SAH)
Subarachnoid hemorrhage secondary to ruptured aneurysm is a critical clinical situation demanding a very skilled surgical and medical management. Until now cerebral digital subtraction angiography (DSA) has been used as the criterion standard for aneurysmal detection and planning of their microsurgical treatment. However, as the method for diagnosis of subarachnoid hemorrhage moved from lumbar ...

After aneurysmal subarachnoid hemorrhage, most center practices treatment modality selection based on size and geometry in computed tomographic angiography. However, the validity as compared to digital subtraction angiography (DSA) is not well studied. Twenty patients with ruptured internal carotid artery aneurysm were identified in a two-year period. Mean difference in measurements from 3D com...

Subarachnoid hemorrhage is a devastating condition due to many etiologies, accounting for 5% of all stroke patients. Rupture of an intracranial aneurysms is most frequent causative factor. The diagnosis is usually easy as clinical symptomatology is quite classical, but diagnosis of warning leaks requires increased degree of suspicion. Non contrast computerised scan (CT) of head is initial inves...

Neuroimaging is a key element in the management of patients suffering from subarachnoid haemorrhage (SAH). In this article, we review the current literature to provide a summary of the existing neuroimaging methods available in clinical practice. Noncontrast computed tomography is highly sensitive in detecting subarachnoid blood, especially within 6 hours of haemorrhage. However, lumbar punctur...

OBJECTIVE Cerebral aneurysms can cause substantial morbidity and mortality, specifically if they rupture, leading to nontraumatic subarachnoid hemorrhage (SAH). This meta-analysis summarizes evidence about the accuracy of noninvasive computed tomographic (CT) angiography for diagnosing intracranial aneurysms in symptomatic patients. METHODS Four databases including PubMed were searched withou...
