Although high technical success and good treatment results were reported in the SAFE study, cases of technical failure of deployment have also been reported. A case in which a FRED was deployed with the proximal part twisted, but successful deployment was achieved, is presented. Case Description: A woman in her 40s was diagnosed with a left internal carotid artery aneurysm during radiological investigations for headaches. Due to her family’s strong history of cerebral aneurysms, she opted for preventive treatment. A 5.5-mm FRED was selected because the proximal vessel diameter was ≥5 mm. However, the stent was deployed with the proximal side twisted. Fortunately, using a Scepter C and a CHIKAI 315 cm, the true lumen could be secure, the wire was guided distally, and the FRED was successfully placed. Later, with the patient’s consent, a 3D blood vessel model was created, and whether the stent was difficult to open or whether it was just a technical problem which was verified experimentally. Precisely, the same situation as during the surgery was recreated, and the stent was deployed in the same way. Conclusion: A FRED is an effective device, but there are cases of difficult deployment. The present method may be an option if a FRED is difficult to open.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/7f640db2-2435-47ec-bdfe-6f6afa320856/featured/hero-1781559333487.png","publishDate":"2024-08-09T00:00:00.000Z","doi":"10.25259/SNI_513_2024","categories":["Neurovascular","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2024/08/13032/SNI-15-278.pdf"}
