Trends and Predictors of Decompressive Craniectomy in Acute Ischemic Stroke, 2011-2020
Journal of Stroke and Cerebrovascular Diseases(2024)
摘要
Introduction
Rates of decompressive craniectomy (DC) in acute ischemic stroke (AIS) have been reported to decline over time, attributed to an increase in endovascular therapy (EVT) preventing the development of malignant cerebral edema. We sought to characterize trends in DC in AIS between 2011 and 2020.
Material and Methods
We performed a retrospective observational study of U.S. AIS hospitalizations using the National Inpatient Sample, 2011 to 2020. We calculated rates of DC per 10,000 AIS among all AIS hospitalizations, as well as AIS hospitalizations undergoing invasive mechanical ventilation (IMV). A logistic regression to determine predictors of DC was performed.
Results
Of ∼4.4 million AIS hospitalizations, 0.5% underwent DC; of ∼300,000 AIS with IMV, 5.8% underwent DC. From 2011 to 2020, the rate of DC increased from 37.4 to 59.1 per 10,000 AIS (p<0.001). The rate of DC in patients undergoing IMV remained stable at ∼550 per 10,000 (p=0.088). The most important factors predicting DC were age (OR 4.88, 95% CI 4.53-5.25), hospital stroke volume (OR 2.61, 95% CI 2.17-3.14), hospital teaching status (OR 1.54, 95% CI 1.36-1.75), and transfer status (OR 1.53, 95% CI 1.41-1.66); EVT status did not predict DC.
Conclusions
The rate of DC in AIS has increased between 2011 and 2020. Our findings are contrary to prior reports of decreasing DC rates over time. Increasing EVT rates do not seem to be preventing the occurrence of DC. Future research should focus on the decision-making process for both clinicians and surrogates regarding DC with consideration of long-term outcomes.
