《急诊每日一题》急性与慢性深静脉血栓超声特点2021年2月

Question 问题：

Chronic postthrombotic change is the radiographic term for residual material and wall thickening that remains in the vein after an acute DVT. How is it differentiated from an acute DVT on ultrasound? 

慢性栓塞后改变是对急性DVT后静脉内残留物和静脉壁变厚的放射学术语。如何从超声影像鉴别急性和慢性DVT？

Answer 答案：

The material is not thrombus and may be differentiated from acute DVT as it is rigid and nondeformable with compression, irregular surfaces, and integrates into the vein wall. 

残留物并不是血栓，它可以与急性DVT通过下列特征区别：质硬，加压后不变形，边缘不规则，并与静脉壁融合。
