[Subarachnoid hemorrhage. Etiopathogenetic aspects]

Area of Science:

• Neurology
• Vascular Medicine
• Neuroscience

Background:

• Subarachnoid hemorrhage (SAH) is a critical neurological condition with significant morbidity and mortality.
• Etiologic and pathogenetic mechanisms of SAH require further elucidation for improved clinical management.

Purpose of the Study:

• To clarify the etiologic and pathogenetic mechanisms of subarachnoid hemorrhage.
• To analyze contributing factors and common vascular pathologies associated with SAH.

Main Methods:

• Review of existing literature on subarachnoid hemorrhage.
• Analysis of clinical data from 60 personal cases of subarachnoid hemorrhage.

Main Results:

• Intracranial arterial aneurysms were identified in approximately 50% of patients.
• Arteriovenous malformations and arterial atherosclerotic lesions were observed in a smaller percentage of cases.
• Specific activities or events preceding the onset of SAH were identified in about 50% of the studied cases.

Conclusions:

• Intracranial arterial aneurysms are a primary cause of subarachnoid hemorrhage.
• Identifying triggers and underlying vascular abnormalities is crucial for understanding SAH.
• Further research into the interplay of vascular lesions and precipitating events can inform prevention and treatment strategies.
