Key result
Transradial approach achieves ~94% procedural success for cerebral angiography in brain ischemia patients.
Why the study?
The safety and feasibility of cerebrovascular angiographic studies using the transradial artery approach in patients with brain ischemia had not been reported.
Is the transradial artery approach safe and feasible for selective cerebral angiography in patients with brain ischemia?
Population
46 consecutive patients with history of stroke, transient ischemic attack, or significant carotid stenosis aged 50 to 83 years

Is the transradial artery approach safe and feasible for selective cerebral angiography in patients with brain ischemia?
The transradial artery approach is a safe and highly successful alternative for selective cerebral angiography in patients with cerebrovascular disease.
Wu et al. (2005) conducted an observational in Brain ischemia (history of stroke, transient ischemic attack, or significant carotid stenosis) (n=46). Transradial artery (TRA) approach using 6 Fr Kimny guiding catheter was evaluated on Overall procedural success (defined as completely evaluating both carotid and vertebral arteries and intracranial vessels). The transradial artery approach for selective cerebral angiography achieved an overall procedural success rate of 93.5% in patients with a history of brain ischemia.
