METHOD FOR INJECTION INTRA-ARTERIAL THROMBOLYSIS USING ULTRASONIC NAVIGATION IN ACUTE ISCHEMIA OF EXTREMITIES Russian patent published in 2024 - IPC A61M25/06 A61B8/08 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to vascular surgery, and can be used for surgical treatment of thrombosis and embolism of arteries by thrombolysis. Under ultrasound control, preparation Actilyse is injected with an initial dose of 15 mg using 23 G needle. Injection is performed strictly through the thrombosed segment; the whole mass of the thrombus is infiltrated by reciprocating needle movements, followed by compression of the puncture zone with an ultrasonic sensor for 3-5 minutes. Further, the patient is heated with a blanket of the Equator system for 2 hours, setting the temperature mode to 44 °C. Then control ultrasonic scanning is performed in 2-4 hours. If thrombotic masses are preserved, the procedure is repeated.

EFFECT: method enables restoring the patency of arteries in thrombosis due to intrathrombotic introduction of tissue plasminogen inhibitor under control of ultrasonic navigation only.
