Background And Purpose: Race/ethnicity is associated with overall incidence of intracranial hemorrhage (ICH), but its impact in patients with brain arteriovenous malformation is unknown. We evaluated whether race/ethnicity was a risk factor for ICH in the natural course in a large, multiethnic cohort of patients with brain arteriovenous malformation followed longitudinally.
Methods: Data were collected prospectively for patients with brain arteriovenous malformation evaluated at the University of California, San Francisco (n=436) and retrospectively through databases and chart review in the 20 hospitals of the Kaiser Permanente Medical Care Program (n=1028). Multivariate Cox regression was performed to assess the influence of race/ethnicity on subsequent ICH, adjusting for risk factors. Cases were censored at first treatment, loss to follow-up, or death.
Results: Average follow up was 4.7+/-8.0 years for Kaiser Permanente Medical Care Program patients and 2.8+/-7.3 years for University of California, San Francisco patients with no difference in time to ICH between cohorts (log rank P=0.57). The annualized 5-year ICH rate was 2.1% (3.7% for ruptured at presentation; 1.4% for unruptured). Initial ICH presentation (hazard ratio: 3.0, 95% CI: 1.9 to 4.9, P<0.001) and Hispanic race/ethnicity (hazard ratio: 1.9, 95% CI: 1.1 to 3.3, P=0.02) were independent predictors of ICH, adjusting for age, gender, cohort, and a cohort-age interaction. The ICH risk for Hispanics versus whites increased to 3.1 (95% CI: 1.3 to 7.4, P=0.013) after further adjusting for arteriovenous malformation size and deep venous drainage in a subset of cases with complete data. Similar trends were observed for blacks (hazard ratio: 2.1, 95% CI: 0.9 to 4.8, P=0.09) and Asians (hazard ratio: 2.4, 95% CI: 0.8 to 7.1, P=0.11), although nonsignificant.
Conclusions: This study reports the first description of race/ethnic differences in brain arteriovenous malformation, with Hispanics at an increased risk of subsequent ICH compared with whites.

Objective: Cerebrovascular diseases are often associated with the development of depression, but few studies have assessed this association with brain arteriovenous malformations (bAVMs). We aim to explore the association of brain arteriovenous malformation(bAVM) with new onset depression at follow-up.
Methods: We performed a retrospective cohort study on adult bAVMs patients using an institutional bAVM database.

Purpose: Intracranial pressure (ICP) monitoring is in most studies considered essential in avoiding secondary brain injury in patients with intracranial pathologies. Invasive monitoring of ICP is accurate but is unavailable in many clinical and prehospital settings. Non-invasive modalities have historically been difficult to implement clinically.
