Glue in Lockdown Technique to Embolize Peripheral Arterial Aneurysms

As a blood flow control technique for embolization using glue (n-butyl cyanoacrylate; NBCA) for peripheral artery aneurysm/pseudoaneurysm, we placed a vascular plug or coils at the proximal inflow vessel before glue injection. We describe this maneuver, which we call the glue in lockdown technique. Four peripheral aneurysms-two pulmonary artery pseudoaneurysms, one pancreaticoduodenal arcade pseudoaneurysm, and one internal iliac artery aneurysm-deemed unsuitable for conventional embolization because of abnormal blood flow, coagulopathy, or anatomical complexity were embolized with our technique. Technical and clinical outcomes were reviewed to evaluate the effectiveness of the procedure. Reliable and rapid embolization was achieved in coagulopathy cases and hemodynamically or anatomically complicated lesions. Glue in lockdown technique was successfully used to treat peripheral aneurysms and can be further developed for application to other lesions.
