Abstract
Objective: We report a case of transbrachial right carotid artery stenting (CAS) without intra-aortic manipulation.
Case presentation: A 71-year-old man presented with right visual field disturbance due to occlusion of the branch retinal artery and symptomatic right internal carotid artery stenosis. Because he had undergone aortic arch replacement for an aortic aneurysm, we planned CAS using the transbrachial approach without intra-aortic manipulation. During the guiding-sheath cannulation, it was difficult to insert a diagnostic catheter directly from the right subclavian artery to the right common carotid artery owing to the acute angle of these arteries. Using the pigtail catheter, the guidewire was easily inserted into the external carotid artery, and stenting was performed successfully.
Conclusion: The pigtail catheter is an useful device for cannulating the guidewire through an acute-angled bifurcation.
