Incidence of intraoperative adverse events (IOAEs) according to the type of stent graft
| Patients presenting with IOAE | F grafts, | B grafts, | P values,a | ||||||
|---|---|---|---|---|---|---|---|---|---|
| Cook F (n = 79) | Ventana F (n = 9) | Anaconda F (n = 8) | All F grafts (n = 96) | Cook B (n = 17) | Cook F vs Anaconda F | Cook F vs Ventana F | Anaconda F vs Ventana F | All F grafts vs B Cook | |
| Type 1 IOAE | 10 (12.7) | 2 (22.2) | 2 (25) | 14 (14.6) | 8 (47.1) | .3 | .6 | 1 | .002 |
| Type 2 IOAE | 4 (5.1) | 0 | 0 | 4 (4.2) | 1 (5.9) | 1 | 1 | 1 | .6 |
| Type 3 IOAE | 8 (10.1) | 0 | 0 | 8 (8.3) | 2 (11.8) | 1 | 1 | 1 | .7 |
| Any type of IOAE | 20 (25.3)b | 2 (22.2) | 2 (25.0) | 24b (25.0) | 10 (58.9)c | 1 | 1 | 1 | .005 |
B, Branched or branched and fenestrated grafts; F, fenestrated; type 1 IOAE, problems with target vessel cannulation; type 2 IOAE, malpositioning of one of the nonfenestrated graft components (bridging stents, bifurcated component, or iliac extensions); type 3 IOAE, difficulty with intraoperative access.
