Linking To And Embedding May-Thurner Syndrome From MetroHealth Emergency Ultrasound

In addition to the resource below posted today, please review Iliofemoral deep vein thrombosis. Last revised by Dr Henry Knipe on 06 May 2020 from Radiopedia:

Iliofemoral deep vein thrombosis (DVT) occurs when a thrombus in the iliac vein (commonexternal or internal) and/or common femoral vein obstructs the venous outflow from the lower limb leading to marked edema. DVT of the IVC or the more distal lower limb veins may also be present.

Deep vein thrombus of the lower limb deep venous system distal to the common femoral vein is termed distal, femoropopliteal or infrainguinal DVT 3.

Iliofemoral deep vein thrombosis accounts for ~25% of all cases of DVT.

Ultrasonography with Doppler is generally the first-line imaging modality for assessing lower limb DVT with high sensitivity (95%) and specificity (96%) 4. This equally applies to DVT of the common femoral veins as for the more distal deep venous system.

However, the diagnosis of DVT of the pelvic veins can be very difficult, if not impossible, with ultrasound, due to multiple factors including bowel gas, large body habitus, normal anatomic depth of the vessels and abdominal pain. Iliac and IVC thrombosis will often require CT and/or MRI.

CT venography and/or MR venography of the pelvis may be required to evaluate the pelvic veins for DVT.

In this post, I link to and embed May-Thurner Syndrome from MetroHealth Emergency Ultrasound, 35:53, Mar 9, 2022.

Note to myself and my readers: The best way to quickly review this excellent teaching video is to watch the video on YouTube. By doing this, you can follow the video using the transcript. And as you go through the transcript you will be automatically reviewing the slides.

I put these resources on my medical education blog because the blog’s WordPress search function easily allows me to quickly find and access my study resources.

Your patient is back again for a DVT. Is there something you should think about this time? In this lecture from our ultrasound lecture series Dr. Matthew Tabbut, MD from the ED talks about a unique condition that predisposes patients to DVTs. This condition is called May-Thurner Syndrome.
