What Researchers Did
Researchers in Japan compared the long-term outcomes of surgical versus nonsurgical treatments for hypertensive putaminal hemorrhage over 15 years to determine the appropriate role of surgery.
What They Found
The study found an overall poor response to surgical treatment for hypertensive putaminal hemorrhage, despite clinical impressions and experimental evidence suggesting potential benefits of hematoma evacuation in some cases. This discrepancy led researchers to propose changing surgical indications from morphological to physiological criteria, such as improvement after hyperbaric oxygen or somatosensory evoked potential changes after mannitol or glycerol administration.
Canadian Relevance
This study was conducted in Japan and has no direct Canadian connection.
Study Limitations
A limitation is that the study's findings on surgical outcomes were based on historical methods for determining surgical indications, which the researchers suggest were not optimal.
