Abstract

Background: a relatively little amount of studies that discuss the optimal imaging method for subarachnoid haemorrhage caused by aneurysmal bleeding. In these individuals, a variety of imaging modalities are used despite the fact that they are seen as invasive, not always accessible, and possibly hazardous to the patient. Consequently, there has been a significant need for non-invasive alternatives.

Aim: To achieve an accurate diagnosis of aneurysmal subarachnoid hemorrhage.

Patients and methods: This comparative cross-sectional study was conducted at the Radiology Department, Zagazig University Hospital on 18 male and female patients with aneurysmal subarachnoid hemorrhage, their ages ranged from 30 to 60 years. Digital subtraction angiography and three-dimensional computed tomography were performed for all cases.

Results: The sensitivity and specificity of digital subtraction angiography in comparison to 3D CT angiography were 98% and 87.5% respectively with statistically significant value (p= 0.035). The true positive was 16 and the true negative was 1.

Conclusion: Recent advances in CT angiography technique, being non-invasive with no procedural neurological complications, add to the advantages of CTA.

Keywords: Aneurysmal subarachnoid hemorrhage, CT angiography, DSA.
