- Risk Factors for Unfavorable Functional Outcome after Endovascular Treatment of Cerebral Vasospasm following Aneurysmal Subarachnoid Hemorrhage
In this study, patients’ individual risk factors, intensity, and extent of cerebral vasospasm associated with poor functional outcomes after endovascular treatment of aneurysmal SAH. Analysis showed an association of higher age, higher Hunt and Hess grades, the occurrence of rebleeding, and bihemispheric vasospasm with unfavorable outcome (mRS 3-6).
- Assessment of Attenuation in Pericarotid Fat among Patients with Carotid Plaque and Spontaneous Carotid Dissection
This cross-sectional retrospective study assessed the PFD in patients with spontaneous internal carotid artery dissection or carotid atherosclerotic plaque, with and without IPH. The results showed that the average PFDs in patients with SICAD and carotid atherosclerosis plaque with IPH were similar and higher than those in patients with carotid plaque without IPH, suggesting a shared pathologic inflammatory mechanism in these 2 conditions.
- Hemodynamic Characteristics in Ruptured and Unruptured Intracranial Aneurysms: A Prospective Cohort Study Utilizing the AneurysmFlow Tool
A DSA-based flow quantification tool (AneurysmFlow) was used to measure blood flow vectors and velocities after contrast injection. Complex flow patterns were shown to be common in ruptured aneurysms and those with daughter sacs. Lowest mean aneurysm flow amplitude in the dome and daughter sacs indicated pathophysiologic changes linked to rupture. Also, hypertension, bifurcation location, and irregular shape of unruptured aneurysm were found to be independent rupture risk factors.
