The angiopathy of subarachnoid hemorrhage: angiographic and morphologic correlates.
In patients with subarachnoid hemorrhage, particularly hemorrhage due to aneurysmal rupture, there was a positive significant relation between angiographic vessel constriction and vessel pathology (angiopathy). Furthermore, there was a positive relationship between post-hemorrhage survival time and the severity of angiopathy. Factors such as age, sex, operations, steroid and CSF pressure seemed to have little affect on angiopathy following hemorrhage. Pathological changes were primarily limited to the involved major cerebral vessels themselves, with their branches rarely being affected. While intramural vascular hemorrhage was a common pathological feature in vessels showing severe pathology, the mere presence of blood surrounding an artery seemed to have little influence on vessel alterations.
