Cerebrovascular disease: evaluation with transbrachial intraarterial digital subtraction angiography using a 4-F
Insights
This study shows that using smaller 4-F catheters for transbrachial digital subtraction angiography in carotid artery disease is effective and safe, with fewer complications than larger catheters.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Diagnostic Imaging
Background:
- Occlusive vascular disease of the carotid arteries poses a significant risk of stroke.
- Intraarterial digital subtraction angiography (DSA) is a key diagnostic tool for evaluating carotid artery disease.
- Minimizing procedural complications is crucial for patient safety and widespread adoption of diagnostic techniques.
Purpose of the Study:
- To evaluate the efficacy and safety of using 65-cm-long, 4-F aortic catheters for transbrachial intraarterial digital subtraction angiography (DSA) in patients with carotid artery disease.
- To compare complication rates with previous transbrachial series using larger (6-8-F) catheters.
Main Methods:
- A retrospective analysis of 361 patients who underwent transbrachial DSA for definite or probable occlusive vascular disease of the carotid arteries.
- Utilized 65-cm-long, 4-F aortic catheters for the procedure.
- Assessed image quality and complication rates, including neurologic deficits, hematomas, and pulse deficits.
Main Results:
- Excellent or good image quality was achieved in nearly all cases.
- No postprocedural neurologic deficits or hematomas were reported.
- A low incidence of permanent pulse deficit (2 patients) and temporary pulse deficit (3 patients) was observed.
- Complication rates were lower compared to previous studies using larger catheters.
Conclusions:
- Transbrachial DSA with 65-cm-long, 4-F aortic catheters is an effective and safe imaging technique for carotid artery disease.
- This technique demonstrates improved safety outcomes, particularly reduced pulse deficits, compared to larger catheter use.
- The study suggests a potential difference in relative safety between men and women, warranting further investigation.
Abstract:
Three hundred sixty-one patients underwent intraarterial digital subtraction angiography for definite or probable occlusive vascular disease of the carotid arteries. Examinations were performed with 65-cm-long, 4-F aortic catheters. A transbrachial approach was used. Images were good or excellent in nearly all cases. No postprocedural neurologic deficits or hematomas occurred. Permanent pulse deficit occurred in two patients, and temporary deficit occurred in three patients, an improvement over the frequency found in previous transbrachial series using 6-8-F catheters. While these results establish the efficacy of this technique, they also indicate a possible greater relative safety in men than in women.
