Carotid artery web is an underrecognized source and is found in about 1-2% of patients with acute ischemic stroke. Although, first described four decades ago, optimal therapy for carotid web is not yet known. Carotid stenting and endarterectomy are increasingly used for carotid web treatment, given its definitive treatment and avoiding the complications associated with anticoagulation. The case reported here is of an ischemic stroke secondary to a mobile thrombus on a carotid web evident on CT angiography and successful definitive treatment with delayed carotid wall stent placement. In young patients who have a diagnosis of ischemic stroke, the carotid web should be on the differential and adequate neuroimaging with either CTA or DSA should be pursued.

✓ The carotid artery (CA) dural ring is an important structure in aneurysm surgery of the paraclinoid region. The authors used three-dimensional computerized tomography (3D-CT) angiography to study the CA dural ring. Three-dimensional computerized tomography angiography was performed in patients with cerebral aneurysms and other cerebrovascular diseases. The paraclinoid segment of the internal carotid artery (ICA) was examined by the shaded surface reconstruction method on targeted 3D-CT angiography. The concavity was recognized in the paraclinoid segment of the ICA. The relationship between the concavity and the dural ring was investigated with anatomical studies and surgical findings. In anatomical studies, the concavity in the paraclinoid segment of the ICA on 3D-CT angiography coincided with the level of attachment of the dural ring. Using 3D-CT angiography, it is possible to identify the location of the dural ring in patients being considered for aneurysm surgery.

Optimal Timing

Background: There are no guidelines for the optimal timing of surgery (emergency vs. delayed) for ascending aortic dissection with acute ischemic stroke. We retrospectively compared the prognoses and radiological and clinical findings for concomitant aortic dissection and ischemic stroke in a series of case reports. Case presentation: Three patients presented with left hemiparesis. Patient 1 underwent surgery for acute aortic dissection without treatment for acute ischemic stroke. In Patient 2, emergency stenting could not be performed due to cardiac tamponade and hypotension. Therefore, emergency acute aortic dissection surgery was performed. Patient 3 underwent emergency right common carotid artery stenting followed by surgery for acute aortic dissection. Brain perfusion computed tomography angiography (CTA) was performed to diagnose severe stenosis of the right common carotid artery or occlusion concomitant with acute aortic dissection involving the aortic arch with a cerebral perfusion mismatch in all the patients. Patient 3 had postoperative local cerebral infarction, whereas patients 1 and 2 (without stent insertion) had extensive postoperative cerebral infarction. Conclusion: Patient 3 showed a better prognosis than patients without stent treatment. We suggest that perfusion CTA of the aortic arch in suspected acute ischemic stroke can facilitate early diagnosis and prompt treatment in similar patients.
