The long-term prognosis in untreated cerebral aneurysms: II. Late morbidity and mortality

摘要: Three hundred sixty-four patients who suffered a subarachnoid hemorrhage from an aneurysm at either the anterior (ACA) or posterior (PCA) communicating artery location and were not surgically treated have been followed for up to 21 years in order study late morbidity mortality. For surviving six months: (1) little improvement was noted during many of subsequent follow-up; (2) general, ACA fared better than PCA patients; (3) neurological state on original admission strongly correlated with degree morbidity; (4) other factors measured time which adversely affected included level blood pressure presence clot spasm; (5) if deaths are excluded, cardiovascular causes account majority deaths; (6) risk dying all is increased when compared population matched by age sex.
