objective to check on color doppler flow imaging in diagnosing venous valvular insufficiency in lower extremity.
目的探讨彩色多普勒超声(cdfi)探测下肢静脉瓣功能不全的新方法及临床应用价值。
methods to chose the 20 healthy and 40 patients (total 59 legs) with venous valvular insufficiency and to apply a cdfi technique to carry on an observation under the condition.
方法选择20例正常对照组及40例下肢深静脉瓣功能不全患者(共59条腿),应用cdfi技术在限定的条件下观察反流束的各项指标及血流动力学改变。
therefore, we think that the relationship between deep venous valvular insufficiency and varicose vein remains to be verified.
因而,作者认为,原发性下肢深静脉瓣膜功能不全与下肢静脉曲张的关系仍有待作进一步的深入研究。
objective to evaluate the application of two dimensional ultrasonography and cdfi in the preoperative diagnosis of deep venous valvular insufficiency of lower extremities.
目的探讨二维超声及彩色多普勒血流显像(cdfi)技术在术前诊断下肢静脉瓣膜功能不全的应用价值。
methods 49 patients with venous valvular insufficiency were examined using 2-d color doppler flow imaging to observe the anatomic structures of valves and hemodynamics of venous flow in legs.
方法应用二维彩色多普勒血流显像检查下肢静脉瓣功能不全49例,观察下肢静脉血管及瓣膜的解剖结构和血流动力学的改变。
