Clinical value of CT angiography before and after deep vein thrombosis of lower limbs
下肢深静脉血栓形成介入治疗前后CT血管成像的临床价值

摘要

目的：研究CT血管成像在下肢深静脉血栓形成介入治疗前后的临床使用效果。方法：选取我院2019年1月~2019年6月期间收治的进行下肢深静脉血栓治疗的患者作为此次研究对象，共计68例。需要研究人员将该部分患者按照数表法分为对照组(34例)与观察组(34例)，对照组下肢深静脉血栓患者运用B超进行治疗结果检测，而观察组下肢深静脉血栓患者采用CT血管成像进行结果检测，研究期间需要护理人员做好记录工作，对比两组患者髂总及髂外静脉、股静脉、腘静脉以及小腿静脉血栓检出例数。结果：观察组下肢深静脉血栓患者采用CT血管成像髂总及髂外静脉血栓检出例数为6例，而对照组下肢深静脉血栓患者运用B超检测检出血栓例数为2例，观察组检出例数明显高于对照组，数据对比存在差异，具有实际统计意义（P＜0.05）。此外，观察组下肢深静脉血栓患者股静脉、腘静脉血栓检出例数分别为11例、12例，相较于对照组患者股静脉检出8例，腘静脉检出7例，研究数据存在差距，具备统计学意义(P＜0.05)。结论：CT血管成像可以有效检测出血栓位置，具有较高检出率，检测图像清晰，值得临床推广使用。

Abstract

Objective: To study the clinical effect of CT angiography before and after interventional treatment of deep vein thrombosis of lower limbs.
Methods: A total of 68 patients who underwent deep vein thrombosis of the lower limbs treated in our hospital from January 2019 to June 2019 were selected. Researchers are required to divide these patients into a control group (34 cases) and an observation group (34 cases) according to the number table method. The patients with lower extremity deep venous thrombosis in the control group were treated with B-ultrasound for examination of the treatment results, while those in the observation group had deep venous thrombosis CT angiography was used to detect the results. Nursing staff needed to make records during the study period, and the number of detected thrombosis in the total iliac and external iliac veins, femoral veins, iliac veins, and calf veins was compared between the two groups of patients.
Results: In the observation group, the number of patients with deep venous thrombosis of the lower extremity using CT angiography and total iliac vein thrombosis were detected in 6 cases, while in the control group, the number of patients with deep venous thrombosis of the lower extremity detected by B- ultrasound was 2.The number of detected cases in the group was significantly higher than that in the control group, and there was a difference in data comparison, which has practical statistical significance (P <0.05). In addition, in the observation group, the number of femoral vein and iliac vein thrombosis detected in patients with deep venous thrombosis of the lower extremities was 11 and 12 respectively, compared with 8 cases of femoral vein and 7 cases of iliac vein detected in the control group.The difference was statistically significant (P <0.05).
Conclusion  : CT angiography can effectively detect the location of the thrombus, has a high detection rate, and the detection image is clear, which is worthy of clinical popularization.
