ABSTRACT
Intra-arterial mechanical thrombectomy (IAMT) for ischemic stroke has high recanalization rate, long treatment time window and low risk of symptomatic intracerebral haemorrhage (sICH), but thrombus fragments produced during treatment can lead to distal embolization. Fragmentation can be reduced if the thrombus is strengthened by increasing the thrombus's crosslink density. Radio frequency (rf) electric current commonly used in surgery to cut and coagulate tissue can induce crosslinking in thrombus. The increase in thrombus stiffness as a result of the increase in crosslinking from rf treatment is characterized in this study. Test results showed that the stiffness of thrombus is increased by more than 8 times after rf treatment. The dramatic increase in stiffness suggests that thrombus fragmentation and distal embolization can be reduced by applying rf during thrombectomy treatment.
