More Details: Abstract There is no effective and noninvasive solution for thrombolysis because the mechanism by which certain thrombi become tissue plasminogen activator (tPA)-resistant remains obscure. Endovascular thrombectomy is the last option for these tPA-resistant thrombi, thus a new noninvasive strategy is urgently needed. Through an examination of thrombi retrieved from stroke patients, we found that neutrophil extracellular traps (NETs), ε-(γ-glutamyl) lysine isopeptide bonds and fibrin scaffolds jointly comprise the key chain in tPA resistance. A theranostic platform is designed to combine sonodynamic and mechanical thrombolysis under the guidance of ultrasonic imaging. Breakdown of the key chain leads to a recanalization rate of more than 90% in male rat tPA-resistant occlusion model. Vascular reconstruction is observed one month after recanalization, during which there was no thrombosis recurrence. The system also demonstrates noninvasive theranostic capabilities in managing pigs’ long thrombi (>8 mm) and in revascularizing thrombosis-susceptible tissue-engineered vascular grafts, indicating its potential for clinical application. Overall, this noninvasive theranostic platform provides a new strategy for treating tPA-resistant thrombi.
