Intracranial mechanical thrombectomy using a proximal balloon guide catheter via a transradial access.

We present a description of a successful recanalization of an intracranial vessel occlusion by stent retriever-based mechanical thrombectomy with a proximal balloon guide catheter introduced via a transradial access. Therefore, we used the radial artery itself as a natural sheath, as the introduction of a balloon guide catheter would not have been possible through a common radial sheath.
