Operation indexes
| Items | ESM group (N = 12) | CSM group (N = 12) | P value |
|---|---|---|---|
| Operation time (min) | 80.58 ± 24.02 | 83.25 ± 22.37 | 0.781 |
| Injection time (min) | 49.58 ± 17.88 | 41.83 ± 17.42 | 0.294 |
| Injection speed (ml/min) | 0.23 ± 0.08 | 0.19 ± 0.06 | 0.167 |
| Injection volume of microspheres (ml) | 0.64 ± 0.11 | 0.53 ± 0.15 | 0.050 |
| Number of animals occurred excessive embolization (n/%) | 3 (25.0) | 3 (25.0) | 1.000 |
| Number of animals occurred microcatheter obstruction (n/%) | 3 (25.0) | 0 (0.0) | 0.217 |
| Number of embolized arteries (n/%) | 47 (100.0) | 46 (100.0) | 1.000 |
| Number of broken arteries (n/%) | 0 (0.0) | 0 (0.0) | 1.000 |
| Number of nontarget-embolized arteries (n/%) | 0 (0.0) | 0 (0.0) | 1.000 |
Data were presented as mean value ± standard deviation or count (percentage). All comparisons between CSM group and ESM group were determined by t test or Chi-Square test. P value < 0.05 was considered significant.
