Higher Hypoperfusion Index Ratio Linked to Increased Risk of Hemorrhagic Transformation After Mechanical Thrombectomy
Researchers at Valley Baptist Medical Center have investigated the relationship between hypoperfusion index ratio (HIR) and the rate of hemorrhagic transformation in patients undergoing mechanical thrombectomy for large vessel occlusion (LVO) stroke. The study, published in Interventional Neuroradiology, found that a higher HIR on admission computed tomography perfusion (CTP) scans
