A Radial Approach Combined With a Contralateral Vertebral Retrograde Approach for Stenting and Coil Embolization of a Large Posterior Inferior Cerebellar Artery Aneurysm.

BACKGROUND

Wide-neck aneurysm embolism is a technically demanding procedure. Stent device deployment is challenging intraoperatively, especially in parent arteries with acute angles.

CASE DESCRIPTION: The authors describe the case of a 74-year female with an unruptured right posterior inferior cerebellar artery aneurysm. The acute angle of the arteries proximal to the posterior inferior cerebellar artery complicated the condition, and the distal end of the guidewire failed to enter the posterior inferior cerebellar artery despite several maneuvers. The wide neck of the aneurysm was located in the posterior inferior cerebellar artery, so a stent was needed. The stent was deployed from the left vertebral artery retrograde to the right vertebral artery.

CONCLUSIONS

The authors report the successful application of a rare strategy, the radial approach combined with a contralateral vertebral retrograde approach, for stent deployment.
