A newly designed puncture needle for suction decompression of giant aneurysms. Technical note

Area of Science:

• Neurosurgery
• Vascular Surgery
• Medical Device Design

Background:

• Aneurysms, particularly large or giant ones, pose significant surgical challenges.
• Effective and safe aspiration techniques are crucial for managing these complex vascular lesions.
• Existing tools may have limitations in preventing blood leakage during aspiration.

Purpose of the Study:

• To describe a novel puncture needle specifically designed for aspirating large or giant aneurysms.
• To highlight the design modifications that prevent blood leakage upon internal needle removal.
• To detail the application of this device in aneurysm treatment.

Main Methods:

• The described puncture needle is a modification of an intravenous catheter with an internal needle.
• It features a lateral tube for aspiration.
• The procedure involves aneurysm puncture with temporary parent artery trapping, followed by catheter positioning using a head frame, brain spatula, and self-retaining retractor.

Main Results:

• The newly designed needle effectively prevents blood leakage when the internal needle is withdrawn.
• The lateral tube allows for controlled blood aspiration using standard operating room suction systems or syringes.
• The device facilitates precise catheter placement for safe and efficient aneurysm management.

Conclusions:

• This modified puncture needle offers an improved method for aspirating large or giant aneurysms.
• Its design addresses the critical issue of blood leakage, enhancing procedural safety.
• The device integrates seamlessly with existing neurosurgical instrumentation for effective aneurysm treatment.
