Clinical value of vascular ultrasound in diagnosis of venous thrombosis of lower extremity
血管超声在诊断下肢静脉血栓中的临床应用价值

摘要

目的 下肢深静脉血栓是临床常见的周围血管性疾病，一旦错过最佳治疗时期会引发肺栓塞，危及患者的生命安全，为了给予患者及时、针对性治疗方案，需要采取现代化技术手段提升该病患者诊断准确率，分析患者病情程度，因此本文探析血管超声在诊断下肢静脉血栓中的临床应用价值。方法 入组样本选自本院收治的下肢静脉血栓患者（研究组）和本院收治的非下肢静脉血栓患者（对照组），观察血管超声检查方法诊断下肢静脉的临床应用价值。结果 研究组患者应用血管超声检验的准确率高达98.11%，与D-二聚体检查无明显差异（P＞0.05），研究组与对照组下肢静脉血管内径各项数值有显著差异，P＜0.05说明存在对比意义。结论 采用血管超声检查方法诊断下肢静脉，准确率极高，可为医生提供准确的病况数据，有利于对症治疗方案的制定及实施，在临床诊断上具有重要意义。

Abstract

Objective Lower limb deep vein thrombosis is a common peripheral vascular disease in clinical practice. Once the optimal treatment period is missed, it can cause pulmonary embolism and endanger the patient's life safety. In order to provide patients with timely and targeted treatment plans, modern technological means need to be adopted to improve the diagnostic accuracy of patients with this disease and analyze the severity of the patient's condition. Therefore, this article explores the clinical application value of vascular ultrasound in the diagnosis of lower limb venous thrombosis.
Methods The enrolled samples were selected from lower limb venous thrombosis patients admitted to our hospital (study group) and non lower limb venous thrombosis patients admitted to our hospital (control group), and the clinical application value of vascular ultrasound examination in diagnosing lower limb veins was observed.
Results The accuracy of vascular ultrasound examination in the study group was as high as 98.11%, and there was no significant difference compared to D-dimer examination (P>0.05). There was a significant difference in various values of lower limb venous vessel diameter between the study group and the control group, with P<0.05 indicating comparative significance.
Conclusion   The use of vascular ultrasound to diagnose lower limb veins has a high accuracy and can provide accurate medical data for doctors, which is beneficial for the formulation and implementation of targeted treatment plans and has important clinical significance.
