      CBF data from the UCSF HIV Over 60 Cohort and the Alzheimer Disease Neuroimaging Initiative were retrospectively evaluated to identify 19 HIV+ older adults, all with plasma viral suppression (including 5 with HIV-associated neurocognitive disorder); 13 healthy, age-matched controls; and 19 participants with early mild cognitive impairment. When accounting for age, education, sex, and vascular risk factors, the HIV+ participants demonstrated alterations in regional cerebral perfusion, including hypoperfusion of bilateral temporal, parietal, and occipital brain regions. This study found significant changes in specific CBF patterns associated with HIV status despite viral suppression.

      Toward Better Understanding of Flow Diversion in Bifurcation Aneurysms
      M. Shapiro, A. Shapiro, E. Raz, T. Becske, H. Riina and P.K. Nelson
      American Journal of Neuroradiology December 2018, 39 (12) 2278-2283; DOI: https://doi.org/10.3174/ajnr.A5874

      Fundamental electric and fluid dynamics principles were applied to generate equations describing the relationships between changes in flow and the degree of vessel coverage in settings of variable collateral support to the jailed territory. The authors studied a simplified hypothetic system with minimum assumptions to generate the most conservative outcomes. Up to 30% metal coverage of any branch territory is very likely to be well-tolerated regardless of device or artery size or the availability of immediate collateral support, provided that no acute thrombus forms to further reduce jailed territory perfusion.
