- Abstract
Fibrinolytic therapy for arterial or venous thrombotic disorders involves the systemic administration of thrombolytics such as streptokinase, which is associated with serious bleeding complications. With this study, we provide a proof-of-concept of photothermal thrombus ablation with gold nanorods exposed to near-infrared irradiation, both in vitro using materials generated from purified fibrinogen or plasma and in vivo in murine blood vessels. This is the first report of the application of photothermal therapy as an anti-thrombotic measure. Remarkably, the addition of streptokinase had a multimodal additive effect with regard to acceleration of photothermal lysis of thrombi even at a dose significantly below the therapeutic concentration, thus minimizing the lifethreatening side effects and adverse complications. This combinatorial approach exhibits great promise for lysing pathological clots while effectively overcoming the drawbacks of existing therapies.
