| Popis: | Objective To compare the usefulness of CT angiography against the gold standard, digital subtraction angiography (DSA), in the characterisation of cerebral arteriovenous malformations (AVM) that present with bleeding. Material and methods We retrospectively analysed patients with intracranial bleeding due to an AVM who were included in a prospective database in the period comprising January 2007 through December 2012. We reviewed radiologic variables such as the characteristics of the AVM (size, location, presence of deep venous drainage), involvement of eloquent areas, and the presence of associated aneurysms. Two neuroradiologists blinded to clinical and radiological information analysed the CT and DSA in consensus. Results A total of 22 patients were included in the study. CT angiography correctly classified 15 of the 16 cases of AVM measuring less than 3 cm (93.75% sensitivity). All cases of deep venous drainage and all those located in eloquent areas were correctly detected (100% sensitivity). The presence of any type of aneurysm related with the AVM was detected in 13 of 15 cases (86.6% sensitivity); 7 of 9 of the intranidal aneurysms were detected (77.78% sensitivity), as were 6 of the 9 flow aneurysms (66.67% sensitivity). Conclusion CT angiography is highly sensitive in the characterisation of cerebral AVMs measuring less than 3 cm, of those located in eloquent areas, and of those with deep venous drainage; it is also highly sensitive in detecting aneurysms related with AVMs. However, CT angiography is less sensitive in detecting intranidal and flow aneurysms related with AVMs. |
