Prognosis of Ruptured Cerebral Arteriovenous Malformations: Is It Better Than Other Causes of ICH?

Perhaps so, though the magnitude of this difference is difficult to establish using administrative data.

Although the conventional wisdom is that intracerebral hemorrhages (ICHs) that are caused by a ruptured brain arteriovenous malformation (AVM) have a better prognosis than other causes of ICH, the rarity of AVMs makes this notion difficult to rigorously evaluate. Moreover, it's unclear whether outcomes would differ simply because the source of bleeding is an AVM, or because the resulting hematomas are different irrespective of etiology, or because AVM patients vary from other ICH patients in other meaningful ways.

Researchers recently addressed this question with a set of two analyses. In the first analysis, researchers used hospital discharge data to identify 619,167 hospitalizations for ICH and the subset (4485; 0.7%) of these cases with “…
