概括
梅-瑟纳综合征 (MTS) 诊断可以通过护理点超声波 (POCUS) 来改善. 这种床边成像可能有助于避免与CT静脉图像 (CTV) 或MR静脉图像 (MRV) 相关的辐射和对比风险,在疑似深静脉血栓症 (DVT) 的高风险患者中.
科学领域:
- 血管外科 血管外科
- 诊断成像 诊断成像 诊断成像
- 放射学 放射学是一门学科.
背景情况:
- 梅-瑟纳综合征 (MTS) 涉及右门动脉对左门静脉进行压缩,经常导致深静脉血栓形成 (DVT).
- 标准诊断包括下肢超声波,CT静脉图像 (CTV) 或MR静脉图像 (MRV) 怀疑近距离DVT当初始超声波是负的.
研究的目的:
- 评估在诊断MTS时的护理点超声波 (POCUS) 的实用性.
- 建议POCUS作为在高风险患者中先进静脉造影之前的初步成像方法.
主要方法:
- 一个病例报告的病人左下肢胀和一个负的初始DVT超声波.
- 计算机断层扫描静脉图 (CTV) 证实了MTS;然后在床边进行POCUS以评估门动脉.
- 在类似的情况下,建议在CTV/MRV之前添加低腹部超声波,使用曲线式探针.
主要成果:
- 最初的下肢DVT超声波是负的.
- 脑电图显示左常见静脉血栓和右常见动脉压缩,诊断MTS.
- 床边POCUS发现与CTV一致,识别了下动脉压缩.
结论:
- 护理点超声波 (POCUS) 可以有效地可视化阴动脉压缩,表明MTS.
- 在CTV或MRV之前实施POCUS可能会减少患者暴露于辐射和IV对比剂.
- 在高风险人群中,POCUS为MTS提供了一个有价值的,可能更早的诊断步骤.

01:20Ultrasound I: Abdominal Ultrasonography
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
