Abstract

Detailed blood flow patterns appear to have a substantial effect upon arterial disease and the outcome of interventional endovascular therapeutic procedures. First, a demonstration of the effect of a stent on eliminating vortex flow in an aneurysm model is given. Next, a method is presented to measure the detailed 3D flow during pulsatile flow in a phantom. Finally, the method is applied to arteriovenous malformations (AVMs). The method consists of the real-time radiographic tracking of contrast droplet paths with images from a biplane pulsed radiographic system used to derive the 3D particle location as a function of time. An example of droplet tracking in a sidewall aneurysm phantom is presented. The application of the method is already impacting the delineation of the detailed morphology and of flow characteristics of AVMs and the selection of transit times for endovascular occlusion of AVMs using cyanoacrylate in patients.
