Summary
Intraarterial digital subtraction angiography is a safe procedure with a low stroke risk of 0.3% in cerebral studies. Overall systemic complications were 1.8%, demonstrating its safety in a large patient cohort.
Area of Science:
- Neurology
- Radiology
- Vascular Imaging
Background:
- Intraarterial digital subtraction angiography (IDSA) is a key diagnostic tool.
- Assessing complication rates is crucial for patient safety and procedure comparison.
- Previous data on IDSA complications, particularly stroke, require contemporary validation.
Purpose of the Study:
- To prospectively evaluate the complication rates of intraarterial digital subtraction angiography.
- To specifically assess the prevalence of stroke and systemic complications.
- To compare complication rates with conventional film angiography.
Main Methods:
- Prospective data collection from 2,475 consecutive patients undergoing IDSA.
- Detailed recording of all systemic complications and neurologic deficits.
- Stratification of complication data based on study type (e.g., carotid/cerebral).
Main Results:
- A low prevalence of stroke (permanent neurologic deficit) of 0.3% was observed in 939 carotid or cerebral studies.
- The overall prevalence of systemic complications was 1.8%.
- No patients required hemodialysis due to renal failure, indicating minimal renal impact.
Conclusions:
- Intraarterial digital subtraction angiography demonstrates a favorable safety profile with low stroke incidence.
- The procedure is associated with a low rate of systemic complications.
- IDSA offers a safe alternative to conventional film angiography regarding complication risks.
