May-Thurner Syndrome is a condition that impacts blood flow and occurs when the right iliac artery compresses the left iliac artery.

Despite the high prevalence, it can remain clinically silent in most patients and is quite challenging to diagnose, in part due to it being asymptomatic unless they develop deep vein thrombosis (DVT).

MTS develops through three stages, starting with asymptomatic left iliac artery compression, which leads to the formation of a venous spur, the second stage. The last stage is the formation of a left lower extremity, such as DVT. However, some people can live with MTS for years without developing DVT.
