Summary
A novel transbrachial angiography technique allows selective visualization of carotid and vertebral arteries. This method proved safe and effective in 25 elderly patients, achieving diagnostic angiograms without complications.
Area of Science:
- Vascular imaging
- Interventional neuroradiology
Background:
- Selective angiography is crucial for diagnosing cerebrovascular diseases.
- The transbrachial approach offers an alternative route for arterial access.
Purpose of the Study:
- To describe a new transbrachial technique for selective cerebral artery angiography.
- To evaluate the safety and efficacy of this technique in geriatric patients.
Main Methods:
- A specialized 4-Fr long catheter and guidewire were used.
- The transbrachial route was employed with a turn-over positioning technique.
- Selective angiograms of internal carotid, external carotid, and vertebral arteries were obtained.
Main Results:
- The technique successfully yielded selective angiograms of target arteries.
- Twenty-five geriatric patients underwent the procedure.
- No persistent complications were reported post-angiography.
Conclusions:
- The described transbrachial technique is a viable method for selective cerebral artery angiography.
- This approach is safe and effective in the geriatric population, minimizing complications.
