超声对下肢深静脉血栓形成致肺栓塞的研究

Clinical value of ultrasonic examination for correlated deep venous thrombosis of lower limbs with pulmonary embolism

目的利用快速、便捷、无创的超声技术研究下肢深静脉血栓形成与肺栓塞的关系。方法对临床综合诊断肺栓塞24例患者行经胸超声心动图和下肢血管超声检查。结果超声心动图发现肺栓塞直接征象5例。发现间接征象10例,主要表现为典型右心负荷过重合并肺动脉高压。血管超声发现下肢深静脉血栓14例。结论超声检查是肺栓塞影像学诊断的首选方法,而且对下肢深静脉血栓形成的诊断更是快速、无创、准确的首选方法,对临床诊断具有很大的帮助。

Objective Study in ultrasonic examination for correlated deep venous thrombosis of lower limbs with pulmonary embolism. Methods Twelve patients with clinically diagnosed pulmonary embolism were performed by transthoracic echocardiography and peripheral vascular ultrasonography. Results The direct signs of pulmonary embolism in Ultrasonography in five patients, included artery thrombus was recognized in the pulmonary artery and in right and left branches of pulmonary artery. The indirect signs of pulmonary embolism were recognized in 10cases; typical right heart overload and pulmonary hypertension were showed. Thrombi in deep veins of the lower limbs were discovered by peripheral vascular ultrasonography in 14 cases. Conclusion Ultrasonic examination is the first choice for clinical diagnosis of pulmonary embolism, and the first choice for diagnosis of Thrombi in deep veins of the lower limbs, which is more prompt safety and precise diagnostic tool, and helpful to making a clinical decision.
