Summary
Histopathological analysis of cerebral aneurysms revealed mucoid deposits and internal elastic lamina changes. These findings, alongside smoking and hypertension, suggest a predisposition to aneurysm formation.
Area of Science:
- Neuropathology
- Vascular Surgery
- Histopathology
Background:
- Cerebral aneurysms pose significant health risks.
- Understanding their histopathological nature is crucial for identifying etiological factors.
Purpose of the Study:
- To investigate the histopathological characteristics of cerebral aneurysms.
- To identify potential risk factors contributing to aneurysm development.
Main Methods:
- A clinico-pathological study of 57 excised cerebral aneurysm sacs.
- Histopathological examination using H&E, Verhoeff van Gieson's, and toluidine blue stains.
- Correlation of histopathological findings with clinical data.
Main Results:
- Aneurysms predominantly affected anterior circulation (52 cases).
- Histopathology revealed mucoid deposits and dystrophic changes in the internal elastic lamina in 35 cases.
- Chronic smoking (26 patients) and hypertension (19 patients) were noted risk factors.
Conclusions:
- Mucoid vasculopathic changes, in addition to smoking and hypertension, may contribute to aneurysm formation.
- These vascular changes may weaken vessel walls, predisposing them to aneurysm development.
