What is intra-arterial thrombolysis?
Intra-arterial thrombolysis involves the administration of agents directly into an artery to break down thrombus. While many agents are available, those used for intra-arterial thrombolysis are classified as plasminogen activators.
Why are thrombolytics contraindicated in stroke?
Intravenous thrombolysis for stroke is contraindicated if the patient is taking therapeutic doses of LMWH because of the presumed high risk of hemorrhagic complications. Reports of IV thrombolysis given to patients taking LMWH are scarce in the literature.
What is intra-arterial therapy?
Abstract. Intra-arterial therapy (IAT) for acute ischemic stroke refers to endovascular catheter-based approaches to achieve recanalization using mechanical clot disruption, locally injected thrombolytic agents or both.

Is intra good for stroke patients?
Intra-arterial therapy has been shown to be efficacious in opening occluded arteries in some patients with severe ischemic stroke.
What is intra-arterial RTPA?
Background: Intra-arterial alteplase (IA tPA) is commonly used during mechanical thrombectomy for acute ischemic stroke in patients with large-vessel occlusion, but specific indications and applications for its use remain undefined.
