[Titanium aneurysm clips and their advantages in diagnostic imaging]

Area of Science:

• Neurosurgery
• Biomaterials Science
• Medical Imaging

Background:

• Aneurysm clips are crucial for securing cerebral aneurysms.
• Traditional alloys may cause imaging artifacts and have varying biocompatibility.
• The Yasargil series is a widely used standard for aneurysm clipping.

Purpose of the Study:

• To evaluate the clinical application and initial outcomes of novel titanium alloy (TiAl6V4) aneurysm clips.
• To assess the imaging performance and artifact reduction capabilities of TiAl6V4 clips compared to conventional alloys.
• To investigate the preliminary safety and feasibility of TiAl6V4 clips in neurosurgical procedures.

Main Methods:

• A prospective study involving 30 patients with 38 aneurysms.
• Application of 45 aneurysm clips made from a titanium alloy (TiAl6V4).
• Comparison of postoperative imaging (CT, angiography, MRI) with conventional alloy clips.

Main Results:

• The TiAl6V4 clips demonstrated superior artifact reduction in CT, angiography, and MRI.
• Metallurgical advantages include better biocompatibility, lower magnetic susceptibility, and reduced X-ray density.
• No immediate adverse events related to the clips were reported in the initial follow-up.

Conclusions:

• Titanium alloy (TiAl6V4) aneurysm clips show promise for improved neurosurgical interventions.
• These clips offer significant advantages in reducing imaging artifacts, enhancing diagnostic clarity.
• Long-term biocompatibility assessment requires extended follow-up beyond the initial 7 months.
