Table 4.
The involvement extent of crural artery lesions.
| Location | <5 cm | 5–10 cm | >10 cm | Total cases | Rate of >10 cm occlusion segments (%) | |||
|---|---|---|---|---|---|---|---|---|
| Stenosis | Occlusion | Stenosis | Occlusion | Stenosis | Occlusion | |||
| Anterior tibial artery | 11 | 8 | 7 | 10 | 9 | 92 | 137 | 67.2 |
| Posterior tibial artery | 7 | 6 | 7 | 9 | 4 | 91 | 124 | 73.4 |
| Peroneal artery | 17 | 7 | 12 | 26 | 10 | 59 | 131 | 45.0 |
The difference of occlusion >10 cm among these three sections was statistically significant (P < 0.01), but P = 0.2719 between anterior and posterior tibial arteries, P < 0.01 between anterior tibial artery and peroneal artery, and P < 0.01 between posterior tibial artery and peroneal artery.
