Long-term prognosis in surgically treated intracranial aneurysms. Part 2: Morbidity

Area of Science:

• Neurosurgery
• Vascular Surgery
• Clinical Outcomes Research

Background:

• Aneurysm surgery aims to improve patient survival and quality of life.
• Evaluating long-term results is crucial for assessing surgical effectiveness.
• Standardized outcome measures are needed for consistent evaluation.

Purpose of the Study:

• To evaluate long-term outcomes in patients following aneurysm surgery.
• To identify predictive factors for successful surgical outcomes.
• To compare results across different outcome measures and with a control group.

Main Methods:

• A population of 204 aneurysm surgery survivors was followed.
• Five distinct outcome measures were employed for evaluation.
• Follow-up duration ranged from 18 months to 5.5 years.

Main Results:

• Outcome assessment varied significantly based on the chosen measure.
• Preoperative and early postoperative variables accurately predicted outcomes.
• Postoperative vasospasm, age, admission blood pressure, and neurological status were key predictors.

Conclusions:

• Long-term results following aneurysm surgery are measure-dependent.
• Predictive models using early clinical data can guide patient management.
• Understanding predictive factors enhances surgical planning and patient selection.
