Optimizing the Radiopacity of an Injectable Polymer on Fluoroscopy used for Treatment of Type II Endoleak After Endovascular Aneurysm Repair.

ABSTRACT:

Purpose

Type II endoleaks (T2EL) are a common complication after endovascular aneurysm repair. AneuFix is a newly designed elastic polymer for T2EL. AneuFix contains tantalum for visualization during fluoroscopy, which is crucial for monitoring the polymer in the side branches. The purpose of this study was to find the lowest concentration tantalum that is sufficient for safe injection in the aneurysmal sac.

Methods

AneuFix polymer with tantalum concentrations between 0 and 30% was injected into endoleak phantoms, connected to a pulsatile flow setup and with a realistic background for fluoroscopy. Furthermore, the radiopacity was investigated on fluoroscopic systems from three different vendors, using static phantoms. Results from both the dynamic and static phantoms were qu
