Why the study?
Elevated blood viscosity is a risk factor for cerebrovascular disease, but its relationship with outcomes of mechanical thrombectomy for large artery occlusion was unknown.
Is high diastolic blood viscosity associated with first-pass reperfusion failure in patients undergoing mechanical thrombectomy for large artery occlusion?
Population
238 patients undergoing mechanical thrombectomy for large artery occlusion
Comparison
Elevated vs lower systolic and diastolic blood viscosity
Design

Higher blood viscosity may reduce first-pass reperfusion after MT for LAO; leaves open whether viscosity-targeted interventions merit prospective trials.
Is high diastolic blood viscosity associated with first-pass reperfusion failure in patients undergoing mechanical thrombectomy for large artery occlusion?
Elevated diastolic blood viscosity is associated with first-pass reperfusion failure, longer thrombus length, and the need for more stent passages during mechanical thrombectomy for acute ischemic stroke.
