Translumbar catheter angiography with a needle-sheath system

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Devices

Background:

• Translumbar catheter angiography is a critical diagnostic tool.
• Minimizing complications during aortic puncture and catheter manipulation is essential for patient safety.
• Existing methods may present risks or limitations in catheter introduction.

Purpose of the Study:

• To evaluate the safety and simplicity of a novel needle-sheath system for translumbar catheter angiography.
• To assess the complication rate associated with this new system.
• To determine the effectiveness of the system in facilitating catheter introduction.

Main Methods:

• A prospective study involving 175 patients undergoing translumbar catheter angiography.
• Utilized a new needle-sheath system for aortic access.
• Assessed complications related to aortic puncture and catheter manipulation.
• Reviewed computed tomography (CT) scans and intraoperative findings for hematomas.

Main Results:

• The translumbar catheter angiography using the new needle-sheath system proved to be a safe and simple technique.
• No complications were observed related to aortic puncture or catheter manipulation in any of the 175 patients.
• The 5-F sheath successfully accommodated 4-F catheters of various lengths and shapes.
• CT scans and intraoperative findings revealed only minimal retroperitoneal hematomas in a subset of patients.

Conclusions:

• The novel needle-sheath system offers a safe and straightforward approach for translumbar catheter angiography.
• This technique minimizes procedural risks, including aortic puncture and catheter-related complications.
• The system's design facilitates versatile catheter use, making it a valuable tool in vascular procedures.
