Optimal Occlusion Pattern for Minimally Invasive Staged Segmental Artery Coil Embolization in a Chronic Porcine Model

In this experimental study on segmental artery coil embolization, the authors examined the optimal occlusion pattern to reduce the risk of spinal cord ischemia during thoracoabdominal aortic repair. Von Aspern and colleagues found that staged regional occlusion, with coiling of lumbar arteries first, leads to better perfusion recovery, no neurological deficits, and no cord tissue damage.
