| Name: | IA Route of Alteplase Administration |
|---|
| Collected For: |
CSTK-05, CSTK-07, CSTK-08, CSTK-09 |
|---|
| Definition: | The route of alteplase administration was intra-arterial (IA). Alteplase may be administered intra-venously (IV) by infusion directly into a vein through a peripheral or central venous catheter, or it may be given through an endovascular mircrocatheter delivery system positioned in an artery to directly infuse alteplase into the clot.

| Notes for Abstraction: |
- If the route of alteplase administration is documented as intra-arterial (IA), select “Yes”.
- If both intravenous (IV) and intra-arterial (IA) alteplase are given either in different procedures or the same procedure, select “Yes”.
Examples:
- “IV alteplase given at hospital ‘A’ prior to transfer to hospital ‘B’ (i.e. drip and ship). Mechanical thrombectomy with IA alteplase was performed at hospital ‘B’”.
- “NIHSS score 3 on arrival to this hospital. IV alteplase initiated in ED with initial improvement noted and NIHSS score zero post-infusion. NIHSS score 5 one hour later. Patient taken to interventional suite and IA alteplase administered.”
- If the only route of alteplase administration was intra-venous (IV) at this hospital or a transferring hospital, select “No”.
- If IA alteplase was administered at another hospital and the patient subsequently transferred to this hospital, select “No”.
