Diagnostic and Therapeutic Role of Spiral CT Angiography in Intracerebral Aneurysms Presenting with Acute Subarachnoid Haemorrhage

Subarachnoid haemorrhage (SAH), which is usually due to the rupture of the intracranial aneurysms, is a severe disease, which is a neurological emergency that requires efficient and reliable diagnosis. Computed Tomography Angiography (CTA) has proved an important non-invasive screening tool in the diagnosis of vascular abnormalities of the brain. Objective: This research was based on the diagnostic value of spiral CTA in detecting intracranial aneurysms in patients discharged with acute spontaneous subarachnoid haemorrhage. Methods: Bands of the 30 patients with non-traumatic SAH who were admitted due to presenting SAH and finally verified on emergency non-contrast CT were examined during a prospective descriptive study. Each of the patients was identified by CTA using a Toshiba Aquilion 16-isce multidetector CT scanner. Pre-contrast, as well as post-contrast images were taken, and 3D reconstructions were provided, which consist of maximum intensity projection (MIP) and volume-rendered imaging. Information on aneurysms was gathered in terms of size, shape, multiplicity, location, and findings connected to the aneurysms, i.e., vasospasm and infarction. Results: This CT angiography was able to detect intracranial aneurysms in every patient. Anterior circulation encompassed 83.3% of all the aneurysms, and the most frequent one, which occurred at the anterior communicating artery. The vast majority of aneurysms were between 3 and 7 mm. CTA was also used, which also showed related complications such as the presence of 30% and infarctions of 10%. The modality was found to be very sensitive to aneurysms that are 3 mm and upwards. Conclusion: Spiral CTA is a fast, dependable, and noninvasive imaging method with high diagnostic value in identifying intracranial aneurysms in the acute SAH. It plays a critical role in early diagnosis, treatment planning, and enhancement of patient outcomes. It can be discussed as one of the main imaging modalities used in assessing emergency neurovascular.
