- Hemorragia Subaracnoideia e Angiografia Cerebral por Tomografia ComputorizadaPublication . Santos, N; Machado, E; Carvalho, S; Barbosa, MD; Martins, FWe present a review of 57 cases of nontraumatic subarachnoid hemorrhagesubmitted to CT angiography of the cerebral vessels. The purpose of our study was to estimate the value of CT angiography in the detection of intracranial aneurysms. These findings were compared with those from selective angiography. The results showed that CT angiography is a rapid, low-risk technique with a low level of invasiveness and high specificity and sensitivity in the detection of cerebral aneurysms, allowing the planning of endovascular intervention and surgical approach.
- Traumatic middle cerebral artery aneurysm secondary to a gunshot wound.Publication . Santos, G; Lima, T; Pereira, S; Macahdo, ETraumatic intracranial aneurysms are rare lesions, accounting for less than 1% of all intracranial aneurysms. Formation of these lesions after a penetrating missile wound is very unusual, and diagnosis can be difficult due to the presence of associated lesions. In this article, we report a case of a woman who developed a middle cerebral artery aneurysm after a gunshot wound, and discuss potential pitfalls found during diagnostic work-up.
