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.

Cerebral artery signal intensity gradient from Time-of-Flight Magnetic Resonance Angiography and clinical outcome in lenticulostriate infarction: a retrospective cohort study
ConclusionCerebral artery SIG from TOF-MRA was significantly associated with short-term functional outcomes in patients with lenticulostriate infarction. Further studies are needed to investigate the temporal relationships of SIG in patients with cerebral infarction.

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.

Long-term outcomes after conservative and EDAS treatment for 111 elderly patients with moyamoya disease: longitudinal and cross-sectional study
CONCLUSIONS: The postoperative long-term stroke rate among elderly patients with MMD was lower in the EDAS group than in the conservative treatment group. Long-term stroke events were associated with advanced age, aneurysm, and initial ischemia after conservative treatment and only initial hemorrhage after EDAS.PMID:37724788 | DOI:10.3171/2023.7.JNS231060

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 ...

Association Between Cervical Fracture Patterns and Blunt Cerebrovascular Injury When Screened with Computed Tomographic Angiography
Vertebral artery injury (VAI) is estimated to be present in upwards of 0.7% of all patients who sustain blunt trauma [1 –7], and in 19-39% of all cervical spine fractures. This is likely due to the close anatomic relationship between the cervical spine and the vertebral arteries. There has been significant interest in determining the risk factors for development of VAI and carotid artery injuries (CAI) because of t he potentially catastrophic outcomes in a missed posterior circulation stroke. If undetected blunt cerebrovascular injuries (BCVI), which include both VAI and CAIs, have significant morbidity and mortality wit...

Computed tomography angiography-based radiomics model to identify high-risk carotid plaques
CONCLUSIONS: The combined model of the radiomics features of carotid plaques and PVAT and the traditional CTA features significantly contributes to identifying high-risk carotid plaques compared with traditional CTA model.PMID:37711840 | PMC:PMC10498225 | DOI:10.21037/qims-23-158

Management of aneurysmal recurrence after Woven EndoBridge (WEB) treatment
Conclusion The retreatment rate after an initial WEB treatment seems to compare favorably with that of coiling. Endovascular treatment of recurrence following WEB implantation is feasible in most situations; it generally requires the use of a stent and leads to a high rate of satisfactory occlusion.

Direct puncture of the superior ophthalmic vein for carotid cavernous fistulas: a 21-year experience
Conclusion Direct SOV cannulation to treat CCFs is safe and effective. Although it is typically used after other endovascular approaches have failed, SOV access for CCF treatment may be warranted as a first-line treatment for select patients.

Relationship between cerebral vasospasm vascular territory and functional outcome after aneurysmal subarachnoid hemorrhage
Conclusions In aneurysmal SAH, left-sided vasospasm is associated with worse discharge functional status. At 6 months, both ACA and BA vasospasm are associated with unfavorable functional status.
