This anatomy offers a “shelf” for right transradial catheters, which provides good stability, even with a tortuous course of the right CCA (<em>A</em>). Frontal roadmap image demonstrates a straight origin of the left CCA from the aortic arch (<em>C, arrow</em>), which allows good navigation of a right transradial catheter. The transverse portion of the aortic arch may act as a shelf for transradial catheters during intervention, providing good stability for an intervention. Frontal roadmap image shows a bovine-type aortic arch with horizontal origin of the left CCA (<em>D, arrow</em>). Access of the left CCA would be easy from a right transradial approach because the catheter can easily move across midline and into the vessel. There would be no risk of catheter herniation.</figcaption></figure> <h3 id="p-3">BACKGROUND AND PURPOSE</h3> <p>Transradial access for neurointerventional procedures has been proved a safer and more comfortable alternative to femoral artery access. We present our experience with transradial (distal radial/anatomic snuffbox and radial artery) access for treatment of intracranial aneurysms using all 3 FDA-approved flow diverters.</p> <div id="sec-2" class="subsection"> <h3 id="p-4">MATERIALS AND METHODS</h3> <p>This was a high-volume, dual-center, retrospective analysis of each institution’s data base between June 2018 and June 2020 and a collection of all patients treated with flow diversion via transradial access. Patient demographic information and procedural and radiographic data were obtained.</p> </div> <div id="sec-3" class="subsection"> <h3 id="p-5">RESULTS</h3> <p>Seventy-four patients were identified (64 female patients) with a mean age of 57.5 years with a total of 86 aneurysms. Most aneurysms were located in the anterior circulation (93%) and within the intracranial ICA (67.4%). The mean aneurysm size was 5.5 mm. Flow diverters placed included the Pipeline Embolization Device (Flex) (PED, <em>n</em> = 65), the Surpass Streamline Flow Diverter (<em>n</em> = 8), and the Flow-Redirection Endoluminal Device (FRED, <em>n</em> = 1). Transradial access was successful in all cases, but femoral crossover was required in 3 cases (4.1%) due to tortuous anatomy and inadequate support of the catheters in 2 cases and an inability to navigate to the target vessel in a patient with an aberrant right subclavian artery. All 71 other interventions were successfully performed via the transradial approach (95.9%). No access site complications were encountered. Asymptomatic radial artery occlusion was encountered in 1 case (3.7%).</p> </div> <div id="sec-4" class="subsection"> <h3 id="p-6">CONCLUSIONS</h3> <p>Flow diverters can be successfully placed via the transradial approach with high technical success, low access site complications, and a low femoral crossover rate.</p> <p><strong data-rich-text-format-boundary="true">Read this article: <a href="https://bit.ly/39Y0OA9">https://bit.ly/39Y0OA9</a></strong></p> </div> </div> ]]></content:encoded> </item> </channel> </rss>
