Study Notes
Cerebral Angiography
- Purpose: Visualizes cerebral blood vessels
- Digital Subtraction Angiography (DSA): Hides surrounding tissues, showcasing only vessels in x-rays
- Procedure Focus: Detects defects, narrowing, or blockages in brain blood vessels
- Location: Radiology department due to contrast dye injection
- Indications: Assess blood flow, identify aneurysms, evaluate tumor vascularity, and potentially treat blood clots or deliver chemotherapy.
Pre-Procedure Considerations
- Pregnancy: Risks to fetus vs. benefits must be considered.
- Dietary Restrictions: Fasting for at least 6 hours; some allow clear fluids until procedure.
- Allergies: Assess for contrast media allergies, and consider preemptive steroids/antihistamines.
- Bleeding/Anticoagulants: Patients with a history of bleeding or taking blood thinners require extra monitoring and precaution post-procedure to manage clotting.
- Kidney Function: Assess BUN and creatinine to evaluate the kidney's ability to process and eliminate dye.
- Relaxation: Mild sedative may be offered. Continuous vital sign monitoring is required.
Procedure Steps
- Positioning: Client lies on a radiography table with head secured.
- Catheter Insertion: Catheter inserted into an artery (groin or neck)
- Dye Injection & Imaging: Contrast dye is injected, and x-rays are taken to capture blood flow.
- Catheter Removal & Closure: Catheter removal is followed by pressure or a device to stop bleeding, and seal the artery.
Post-Procedure Considerations
- Clotting Monitoring: Closely monitor the insertion site for clotting.
- Movement Restrictions: Movement may be limited to prevent rebleeding at the catheter site.
- Neurological Assessments: Frequent neuro assessments and vital signs monitoring post procedure
- Cold Compress: Apply ice pack to insertion site.
- Hydration: Encourage fluids to hasten dye excretion.
Complications
- Bleeding: Risk of bleeding or hematoma formation at the catheter insertion site.
- Monitoring: Frequent checks of the artery insertion site area, and assessments of the affected extremity distal to the puncture site for circulation (color, temperature, pulses, capillary refill).
- Intervention: Apply pressure over the artery; consult the provider if significant bleeding occurs.
