| 目的 探讨微血流成像(MFI)联合超声造影(CEUS)诊断及定位肾创伤伴活动性出血的应用价值。方法 健康巴马小型猪10只,建立肾创伤伴活动性出血模型。模型建立后依次进行灰阶超声、彩色多普勒血流成像、CEUS及MFI联合CEUS检查。比较MFI联合CEUS与CEUS诊断及定位活动性出血的准确性,并评价肾创伤伴活动性出血受损血管内径。结果 成功建立巴马小型猪肾创伤伴活动性出血18处。CEUS与MFI联合CEUS诊断活动性出血的准确性分别为77.78%和94.44%,无统计学差异(P>0.05)。CEUS与MFI联合CEUS定位诊断活动性出血的准确性分别为55.56%和94.44%,差异具有统计学意义(P<0.05)。MFI联合CEUS测量活动性出血受损血管内径为1.54-2.42mm。结论 MFI联合CEUS能清晰显示肾创伤伴活动性出血的受损血管,准确诊断活动性出血,并提高定位活动性出血部位的能力,为指导临床微创介入止血治疗和预后评估提供更多的诊断信息。 |

| Abstract: |
| Objective To explore the application value of micro flow imaging (MFI) combined with contrast-enhanced ultrasound (CEUS) in the diagnosis and localization of active bleeding from renal trauma. Methods The model of renal trauma with active bleeding was established in 10 healthy Bama miniature pigs. B-mode ultrasound, color Doppler flow imaging, CEUS and MFI combined with CEUS were performed successively after the model was established. The accuracy of CEUS and MFI combined with CEUS in the diagnosis and localization of active bleeding from renal trauma were compared. The inner diameter of damaged vessels in renal trauma with active bleeding was measured on MFI combined with CEUS images. Results 18 cases of renal trauma with active bleeding were successfully established in Bama miniature pigs. The accuracy of CEUS and MFI combined CEUS in the diagnosing of active bleeding was 77.78% and 94.44%, respectively, and the difference was not statistically significant (P>0.05). The accuracy of CEUS and MFI combined CEUS in the localization of active bleeding was 55.56% and 94.44%, respectively, and the difference was statistically significant (P<0.05). The inner diameter of damaged vessels in renal trauma with active bleeding on MFI combined with CEUS images was 1.54-2.42 mm. Conclusion MFI combined with CEUS can clearly display the damaged vessels of renal trauma with active bleeding, accurately diagnose active bleeding, and improve the ability to locate active bleeding, providing more diagnostic information for guiding clinical minimally invasive interventional hemostasis and prognosis evaluation. |
