Intra-arterial Thrombolysis (IA t-PA)

Intra-arterial (IA) thrombolysis is an advanced treatment of an ischemic stroke (a blockage of a blood vessel in the brain) that is only available at specialized facilities. In this procedure a catheter is navigated to the blocked blood vessel and tPA (tissue plasminogen activator) or clot-busting drug is delivered directly at the site of the clot to dissolve it and re-open the vessel.
