| 目的 探讨二维超声血流(B-Flow)显像技术在评判下肢深静脉倒流性疾病中的价值。方法 对50例下肢静脉病患者的股浅静脉第一瓣及大隐静脉瓣膜处,用黑白二维、B-Flow技术、彩色多普勒(CDFI)技术进行术前超声血流动力学检测,将检测结果与临床症状、术中探查的静脉瓣膜反流程度相比较。结果 B-Flow能显示血流状态下的股浅静脉第一瓣活动情况;术前测得股浅静脉第一瓣处内径与术中探查深静脉反流程度相关有高度统计学意义(P=0.004);术前测得股浅静脉第一瓣膜反流指数与术中探查深静脉反流程度相关有高度统计学意义(P=0.000),但反流时间与术中探查深静脉反流程度相关性无统计学意义(P>0.05)。结论 B-Flow技术在评判下肢深静脉倒流性疾病中有实用价值。 |

| Objective To evaluate the value of B-flow ultrasonography in examining deep vein reflux of the lower extremities. Methods There were 50 patients suspected deep vein reflux underwent 2-D real-time image,B-flow ultrasonography and color Doppler flow imaging (CDFI).The results of the mobility and texture at the first valve of superficial femoral vein and the valve of great saphenous vein on 2-D image,B-flow and CDFI were compared with the severity of venous reflux confirmed by the surgery. Results The structure of the first valve of the superficial femoral vein was clearly showed on B-flow ultrasonography.Comparing B-flow ultrasonography with surgical results,the valve reflux index and the diameter of the superficial femoral vein at the level of the first valve were correlated with the severity of venous reflux,but not the time of valve reflux. Conclusion B-flow ultrasonography is very helpful in detecting deep vein reflux of the lower extremities. |
