[Neuropathological study of adult intracranial hemorrhage. General data in 500 cases]
Insights
High blood pressure is a primary cause of cerebral hemorrhages (C.H.). However, liver cirrhosis and anticoagulant therapy also play significant roles in various intracranial hemorrhages (ICH), particularly subdural hematomas (S.H.).
Area of Science:
- Neuropathology
- Clinical Neurology
- Epidemiology of Cerebrovascular Diseases
Context:
- Intracranial hemorrhages (ICH) represent a significant neurological emergency.
- This study analyzed 500 cases of ICH, focusing on etiological factors, complications, and outcomes.
- Data were primarily sourced from neurological and neurosurgical departments.
Purpose:
- To systematically investigate the pathological and etiological aspects of various types of intracranial hemorrhages.
- To determine the primary etiological factors for cerebral hemorrhages (C.H.), meningeal hemorrhages (M.H.), and subdural hematomas (S.H.).
- To compare the incidence of etiological factors in the studied population with general population data.
Summary:
- High blood pressure is the leading cause of cerebral hemorrhages (C.H.), observed in 68% of ICH cases.
- Liver cirrhosis was found to have a higher incidence than previously reported, though its direct etiological contribution to C.H. requires further investigation.
- Anticoagulant therapy was notably prevalent in subdural hematomas (S.H.), although trauma remained the more significant etiological factor for S.H.
Impact:
- Highlights the multifactorial nature of intracranial hemorrhages, extending beyond hypertension.
- Suggests a need for further research into the role of liver cirrhosis in cerebral hemorrhages.
- Provides crucial etiological insights for the management and prevention of different types of intracranial hemorrhages.
Abstract:
The systematic pathological study of 500 patients with intracranial hemorrhages (ICH) [341 (68 P. 100) CEREBRAL HEMORRHAGES (C.H.); 119 (24 p. 100) meningeal hemorrhages (M.H.); 39 (7,8 p. 100) subdural hematomas (S.H.) and, at last, one extradural hematoma] has been practiced. Those cases were issued primarily from neurological and, at a lesser degree, from neurosurgical departments. Etiological data, complications, associated findings and causes of death have been analysed. High blood pressure is the main etiological factor in C.H. This is confirmed by the statistical comparison between the incidence of this factor in our material and in the whole French population. However, nearly 50 p. 100 of ICH occuring in normotensive patients are C.H. The incidence of cirrhosis is much higher in our study than in other reports from the literature. The frequently associated high blood pressure does not seem to enhance the incidence of CH in patients with liver cirrhosis. Although this last factor can be found alone, its real etiological importance in CH cannot be assessed on account of the lack of data concerning the incidence of liver cirrhosis in the French population. The incidence of anticoagulant therapy is high in S.H. On the contrary, this factor does not seem to enhance the risk of high blood pressure induced C.H. The traumatic etiology of S.H. is significantly higher than the anticoagulant therapy etiology which, however, is very high in our study.
