Individualized left transradial access for flow-diverter treatment in a patient with coexisting aberrant right subclavian and brachioradial arteries: A technical case report
Case report demonstrates successful flow-diverter deployment in a patient with coexisting right-sided arterial anomalies, indicating the feasibility of individualized left-arm access.
Key Points
To describe the procedural strategy of using left transradial access for flow-diverter deployment in a patient with coexisting aberrant right subclavian and brachioradial arteries.
Evaluated a 38-year-old woman presenting with a left internal carotid artery paraclinoid aneurysm and dual right-sided anatomical variations (ARSA and brachioradial artery).
Switched to left transradial access with preprocedural arm angiography and utilized a Simmons-type guiding system after right-sided access failed selective anterior circulation catheterization.
Successfully navigated and deployed the flow-diverter stent across the left internal carotid artery paraclinoid aneurysm via the left radial artery.
Achieved stable catheter support throughout the intervention with no procedural instability or major access-site complications.
