Fibromuscular dysplasia incidentally identified with computed tomography angiography
A 78-year-old woman had presented to the emergency room with altered mental status after the inadvertent consumption of a cannabis product. A stroke workup was initiated, including computed tomography angiography, which demonstrated severe tortuosity and a beaded appearance of her bilateral internal carotid arteries (A/Cover and B). The radiographic imaging findings, including alternating areas of bulging and narrowing, were consistent with fibromuscular dysplasia (FMD; C). The patient denied any history of transient ischemic attack, cerebrovascular accident, amaurosis fugax, or chronic kidney issues.

Case report: Retrograde endovascular recanalization of vertebral artery occlusion with non-tapered stump via the deep cervical collateral
ConclusionAntegrade endovascular recanalization of VA occlusion with a non-tapered stump is a challenge. The retrograde endovascular method via the cervical collateral may be an alternative for this type of VA occlusion, which requires further exploration.

Angiography-based hemodynamic features predict recurrent ischemic events after angioplasty and stenting of intracranial vertebrobasilar atherosclerotic stenosis
ConclusionsIn patients with intracranial vertebrobasilar atherosclerosis treated with PTAS, preprocedural prolonged TTP of the target vessel and shortened trans-stenotic TTP difference were associated with stroke relapse. Q-DSA-defined hemodynamic parameters provided incremental predictive value over conventional parameters for stroke recurrence.Clinical relevance statementQuantitative DSA analysis enables intuitive observation and semi-quantitative evaluation of peri-therapeutic cerebral blood flow. More importantly, quantitative DSA –defined hemodynamic parameters have the potential for risk stratification of patients ...

Selecting stroke patients for thrombectomy: is CTA+ASPECTS enough?
Since 2014, a series of randomised controlled trails (RCTs) have demonstrated the benefit of endovascular thrombectomy (EVT) on functional outcome for the participants who had acute ischaemic stroke (AIS) with occlusion of a proximal intracranial artery in the anterior circulation. The characteristics of the people enrolled in these RCTs have been used to define recommended criteria to select patients for thrombectomy in clinical practice. The initial group of RCTs largely enrolled participants early after AIS (mostly under 6 hours) who had National Institutes of Health stroke scale scores ≥6 (range 0–42 with lowe...

Thoracic Aortic Plaque Burden and Prediction of Cardiovascular Events in Patients Undergoing 320-row Multidetector CT Coronary Angiography
CONCLUSIONS: We found that comprehensive non-invasive evaluation of TAPB and CAD has prognostic value in MACE risk stratification for suspected CAD patients undergoing CCTA.PMID:37704429 | DOI:10.5551/jat.64251

Cervical dumbbell-type tumor spontaneously shrinking following an ischemic stroke
CONCLUSION: Here, we report on a 57-year-old man with cervical MR images revealing that a cervical dumbbell schwannoma was progressively compressing both the spinal cord and the right vertebral artery. However, following a cerebral infarction, the tumor underwent spontaneous shrinkage over the next 4 years, thus relieving the compression.PMID:37680907 | PMC:PMC10481817 | DOI:10.25259/SNI_613_2023

Acute and subacute neurovascular impact of cryptogenic air emboli
CONCLUSION: This case highlights that cerebral air emboli can cause delayed ischemia that may not be appreciated on initial imaging. As such, affected patients may require intensive neurocritical care management, close neurologic monitoring, and repeat imaging irrespective of initial radiographic findings.PMID:37680929 | PMC:PMC10481802 | DOI:10.25259/SNI_382_2023
