- Perivascular Spaces Are Associated with Atherosclerosis: An Insight from the Northern Manhattan Study
Perivascular spaces may be associated with cardiovascular and dementia risks and these authors sought to determine if they are also associated with atherosclerosis. Thus, perivascular spaces were assessed in more than 700 patients and correlated with race, age, and cardiovascular risks. They were found to be more common in older hypertensive patients and the presence of carotid artery plaques strongly and consistently predicted their presence.
- Hemodynamic Effects of Developmental Venous Anomalies with and without Cavernous Malformations
Perfusion imaging was done in patients with developmental venous anomalies with and without accompanying cavernous malformations. The normal-appearing brain surrounding DVAs showed higher blood volume, longer mean transit time, and variable changes in blood flow. DVAs with cavernomas showed greater MTT prolongation and less blood flow indicating greater restrictive effects upon the adjacent brain. The authors offer some ingenious and interesting explanations for these findings.
