SideEye: Performance Evaluation For Fenestrated Endovascular Aneurysm Repair Procedures

Fenestrated endovascular aneurysm repair presents a significant technical challenge in cases involving complex anatomy. This complexity often leads to difficulties target vessel cannulation, prolonged procedure time, and increased fluoroscopy radiation exposure. To address these challenges, this paper aims design, develop, assess novel steerable catheter, the SideEye (Fig 1), compare its performance that of conventional catheters thoracoabdominal aortic phantom model. Seven users were asked perform cannulation using catheter two (one non-steerable one steerable) under fluoroscopic guidance. The study was designed with experimental cases: aligned misaligned stent graft orientation. primary outcome measures for total time individual times. Exposure times also recorded exposure associated each catheter. In case, average all vessels 703 ± 274 seconds 517 309 199 91.0 2). analyzed case. had an 12 4.6 minutes, 8.6 4.1 3.0 1.1 minutes These results indicate difference between (P < .05).
