<meta name="DC.Description" content="BACKGROUND AND PURPOSE: The purpose of this study was to measure the changes in the intraaneurysmal fluid pressure and parent vessel flow characteristics resulting from packing the aneurysmal sac with hydrogel-coated coils.

METHODS: Platinum coils coated with an expansible hydrogel were used to embolize a silicone model of the basilar tip aneurysm. The intraaneurysmal fluid pressure was measured with a NeuroCare Camino Pressure Micro-Probe at various packing ratios. A programmable pulsatile pump was used to input a physiologically relevant pulsatile flow in the parent artery.

RESULTS: The intraaneurysmal fluid pressure did not increase when packing the aneurysm with hydrogel-coated platinum coils, even with a coil density up to 93%.

CONCLUSION: Packing the aneurysm with hydrogel-coated coils at a density up to 93% did not increase the intraaneurysmal fluid pressure." />

The intraaneurysmal fluid pressure was measured with a NeuroCare Camino Pressure Micro-Probe at various packing ratios. A programmable pulsatile pump was used to input a physiologically relevant pulsatile flow in the parent artery.</p><p id="p-3"><em>RESULTS:</em> The intraaneurysmal fluid pressure did not increase when packing the aneurysm with hydrogel-coated platinum coils, even with a coil density up to 93%.</p><p id="p-4"><em>CONCLUSION:</em> Packing the aneurysm with hydrogel-coated coils at a density up to 93% did not increase the intraaneurysmal fluid pressure.</p></div><ul class="copyright-statement"><li class="fn" id="copyright-statement-1">American Society of Neuroradiology</li></ul><span class="highwire-journal-article-marker-end"></span></div><span class="related-urls"></span></div><a href="http://ajnr-stage2.stage.highwire.org/content/26/4/904.full" class="hw-link hw-link-article-full-text" data-icon-position="" data-hide-link-title="0">View Full Text</a></div>  </div>
