Study Notes
Surgical Interventions for Stroke
-
Carotid Endarterectomy - A surgical procedure to remove atherosclerotic plaque from the carotid artery bifurcation.
- Performed in patients who have had transient ischemic attacks (TIAs) or are at risk of stroke.
- Involves clamping the carotid artery, making an incision, removing plaque, and suturing/grafting to restore blood flow.
-
Extracranial-intracranial Bypass - A surgical procedure for occluded or stenotic vessels not amenable to arterial clearance using radiologic visualization.
- May be performed on the internal carotid, middle cerebral, or vertebral arteries.
- Used for patients experiencing ischemia due to TIAs or mild strokes.
- Reconnects blood flow to the affected brain area.
-
Carotid Angioplasty with Stenting - A minimally invasive procedure used to widen narrowed carotid arteries.
- Used for cerebral stenosis.
Medication: Thrombolytics
-
Tissue Plasminogen Activator (tPA) - A drug that dissolves blood clots. Alteplase (Activase) is the only tPA indicated for stroke.
- Mechanism of Action: Binds to fibrin in blood clots, converting plasminogen to plasmin, which destroys fibrin.
- Administration: Must be administered within 12 hours of symptom onset, ideally within 3 hours for optimal results.
- Nursing Considerations: Monitor for bleeding rigorously, as tPA dissolves all clots.
- Contraindications: Do not administer to patients with recent trauma, falls, or motor vehicle accidents.
Stroke Rehabilitation Therapies
-
Physical Therapy: Helps prevent contractures and improves muscle strength and coordination.
- Focuses on regaining mobility skills like walking, sitting, lying down, and transitioning between movements.
-
Occupational Therapy: Provides assistive devices and strategies for regaining lost motor skills.
- Addresses activities of daily living, such as eating, drinking, bathing, cooking, reading, writing, and toileting.
- Speech and Language Therapy: Helps patients relearn language and communication skills, and address swallowing difficulties.
