Glue in Lockdown Technique to Embolize Peripheral Arterial Aneurysms

Area of Science:

• Interventional Radiology
• Vascular Surgery
• Medical Device Technology

Background:

• Peripheral artery aneurysms and pseudoaneurysms pose treatment challenges, especially with abnormal blood flow or coagulopathy.
• Conventional embolization techniques may be insufficient for anatomically complex or hemodynamically challenging lesions.

Purpose of the Study:

• To introduce and evaluate the efficacy of the "glue in lockdown technique" for embolizing peripheral artery aneurysms/pseudoaneurysms.
• To assess the technical and clinical outcomes of this novel blood flow control method.

Main Methods:

• The "glue in lockdown technique" involves placing a vascular plug or coils proximally before n-butyl cyanoacrylate (NBCA) glue injection.
• Four challenging peripheral aneurysms (pulmonary artery pseudoaneurysms, pancreaticoduodenal arcade pseudoaneurysm, internal iliac artery aneurysm) were treated.

Main Results:

• The technique enabled reliable and rapid embolization, even in cases with coagulopathy.
• Successful treatment was achieved for hemodynamically and anatomically complicated peripheral aneurysms.
• The procedure demonstrated technical success and positive clinical outcomes.

Conclusions:

• The "glue in lockdown technique" is a safe and effective method for treating peripheral artery aneurysms and pseudoaneurysms.
• This approach offers a viable solution for complex cases where conventional embolization is not feasible.
• Further development and application of this technique for other vascular lesions are warranted.
