Microcatheter shaping using three-dimensional printed models for intracranial aneurysm coiling.

abstract：:Several anatomical variations of the radial artery have been described in the literature. Common variations include radial artery loop, recurrent branch, and anastomotic channels connecting the radial and brachial arteries. These variations can pose significant technical challenges to safe radial artery catheterizatio...
