Several duplex ultrasound images are displayed to make an informed diagnosis of iliac vein obstruction. Figure 1 and Figure 2 demonstrate examples of patients with vein compression, and Figure 3 and Figure 4 show patients with different forms of vein occlusion.

May-Thurner Syndrome is a condition in which the left common iliac vein is compressed by the right common iliac artery, increasing a patient’s risk of developing deep vein thrombosis in the left lower extremity.

2024年10月5日 · Ultrasound is one of the most common and non-invasive techniques used to visualize the external iliac vein. Doppler ultrasound is particularly useful because it allows doctors to assess both the structure and the blood flow through the vein.

Venous duplex ultrasound imaging of the retroperitoneal iliac veins and vena cava has been slow to be adopted into everyday use; however, current ultrasound technology allows more depth of penetration with improved image resolution.

2024年10月20日 · Ultrasound is often the first-line imaging test used to evaluate the iliac vein. This non-invasive method uses high-frequency sound waves to create images of blood vessels and tissues. Ultrasound can help detect blockages …

The objective is to assess the inferior vena cava (IVC); bilateral common, external, and internal iliac veins; common femoral, femoral, and deep femoral veins; left renal vein; and bilateral gonadal veins to rule out thrombus, stenosis, compression, and incompetence.

2024年10月5日 · Key Imaging Techniques for the Internal Iliac Vein. 1. Ultrasound Imaging of the Internal Iliac Vein. Ultrasound is often the first imaging technique used to evaluate the internal iliac vein. It is non-invasive, widely available, and provides real-time images of blood flow.
