Time management in acute vertebrobasilar occlusion.

Area of Science:

• Neurology
• Interventional Radiology

Background:

• Acute vertebrobasilar occlusion (VBO) carries a high risk of stroke and mortality.
• Local thrombolysis can achieve recanalization but mortality remains high (35-75%).
• Poor outcomes are common without recanalization (80-90% mortality).

Purpose of the Study:

• To evaluate the impact of time management in the diagnostic and interventional workflow for acute VBO.
• To identify factors influencing outcomes after local thrombolysis for VBO.

Main Methods:

• Retrospective analysis of data from 18 VBO patients.
• Correlation of time intervals (symptom onset, admission, diagnosis, intervention) with neurological status.
• Assessment of neurological status using Glasgow Coma Scale and NIHSS before and after intervention.
• Application of multivariate statistics to identify patient similarities and outcome predictors.

Main Results:

• Primary recanalization achieved in 77% of patients.
• Overall mortality rate was 55%.
• Shorter time from symptom onset to intervention correlated with better post-interventional NIHSS scores and outcomes, particularly within a 4-hour interval.
• Major complications included intracranial hemorrhage and peripheral embolism.

Conclusions:

• Efficient intrahospital workflow is crucial for improving outcomes in acute VBO.
• Similar to acute coronary interventions, short symptom-to-intervention times are vital for favorable outcomes in VBO.
• Multivariate statistical evaluation aids in defining patient similarities and optimizing treatment strategies for VBO.
