UShow Case | AI-Assisted Catheter Shaping for a Posterior Communicating Artery Aneurysm at Beijing Anzhen Hospital

A clinical team led by Professor Huo Xiaochuan at Beijing Anzhen Hospital, Capital Medical University, successfully performed stent-assisted coil embolization for a left posterior communicating artery (PComA) segment aneurysm using UnionStrong®'s AI Catheter Shaping Robot.

The patient, a 64-year-old man with hypertension, presented with an aneurysm discovered during an MRI examination following dizziness.

The AI system reconstructed the patient's cerebral vasculature in 3D, automatically segmented the aneurysm, and measured key morphological parameters. Based on the vascular anatomy and microcatheter characteristics, it generated a personalized shaping plan, which was executed through automated robotic shaping.

Despite the challenging vascular curvature and downward-oriented aneurysm dome, the shaped microcatheter reached its intended position on the first attempt, maintaining stable support throughout coil deployment.

Postoperative angiography demonstrated satisfactory aneurysm occlusion and preserved patency of the parent artery.

This case highlights the potential of AI-assisted catheter shaping to support precise microcatheter positioning, procedural stability, and more standardized neurointerventional workflows.
