Evaluation of hemolysis in microcatheter directed blood infusion at different flow rates for transarterial salvage reperfusion: In-vitro study

Abstract

BACKGROUND: Microcatheter directed blood reperfusion is an endovascular salvage option for acute cerebral artery occlusions. It has not been investigated whether this technique may be associated with hemolysis. OBJECTIVE: Analysis of hemolysis during blood infusion through different microcatheters and infusion rates to assess related risks. METHODS: Four microcatheters with different inner diameters were perfused with blood samples at three infusion rates. Hemolytic markers including lactate-dehydrogenase (LDH) and haptoglobin were analyzed. Samples before and after blood infusion were compared using Student's t -test. Flow-related degree of hemolysis was analyzed with regression analysis. R..
