Ischemic stroke — thrombectomy window?

Basic window: up to 6 h from onset. Extended (DAWN/DEFUSE-3) up to 24 h in selected cases with clinical-radiologic mismatch, adequate ASPECTS and proximal occlusion.

Incidental aneurysm — when to treat?

Multidisciplinary decision. Consider: size (≥ 7 mm generally), location (posterior > anterior circulation), irregular morphology, symptoms, prior SAH and patient risk factors (PHASES score).

Report template — CT of venous intracranial

When to use

Cervical/intracranial arterial and venous CTA is the method of choice in emergency for stroke with suspected large-vessel occlusion, subarachnoid hemorrhage (ruptured aneurysm workup), cerebral venous thrombosis and cervical arterial dissection.

What to evaluate

Carotid and vertebral patency (stenoses, occlusions, dissections).
Circle of Willis: ACA, MCA, PCA and anatomical variants.
Aneurysms: location, size, morphology (saccular, fusiform), rupture signs.
Venous system: dural sinuses and deep cerebral veins — thrombosis signs (filling defects).
In stroke: identify proximal occlusion (M1, ICA, ACA-A1, basilar) for thrombectomy eligibility.

Técnica: Exame realizado pela técnica multislice após a injeção do meio de contraste endovenoso. Análise: - Porção cranial das veias jugulares internas: calibre, trajeto e contrastação preservados. - Seios sagital superior, reto, transversos e sigmoides: calibre, trajeto e contrastação preservados. - Veia de Galeno e veias cerebrais internas: calibre, trajeto e contrastação preservados. - Circulação patológica: ausente. - Trombose venosa recente: ausente. - Variações anatômicas: assimetria do calibre entre as veias jugulares internas e os seios sigmoides e transversos, menores à . Comparação: Estudos anteriores não disponíveis. Conclusão: Angiotomografia venosa cerebral dentro dos parâmetros da normalidade.
