|May 11, 1999
Summary
In 1993, 439 Taiwanese patients had ruptured intracranial aneurysms. Surgical treatment had a 13% mortality rate, with clipping being the most common procedure.
Area of Science:
- Neurosurgery
- Neurology
- Epidemiology
Background:
- Intracranial aneurysms pose a significant risk for cerebrovascular events.
- Understanding the epidemiology and treatment outcomes is crucial for patient management.
Purpose of the Study:
- To report the incidence, anatomical distribution, treatment modalities, and surgical mortality of ruptured intracranial aneurysms in Taiwan.
Main Methods:
- Prospective survey and registry of stroke cases in Taiwan.
- Data collection on aneurysm occurrence, location, and treatment.
- Analysis of surgical and interventional treatment outcomes.
Main Results:
- 439 cases of ruptured intracranial aneurysms reported in 1993.
- Common locations: internal carotid artery-posterior communicating artery (32%), anterior communicating artery (30%), middle cerebral artery (18%).
- Surgical clipping was the predominant treatment (88%), with an overall surgical mortality of 13%.
Conclusions:
- Ruptured intracranial aneurysms represent a serious health concern in Taiwan.
- Neurosurgical interventions, primarily clipping, are associated with significant mortality.
- Further research into preventative and therapeutic strategies is warranted.
