A Comprehensive Review Article on May-Thurner or Cockett Syndrome

Abstract

May-Thurner syndrome—it is also called iliocaval compression syndrome, Cockett syndrome or iliac veincompression syndrome, which occurs secondary to compression of the left iliac vein by the overriding rightiliac artery. In the mid-19th century, it was observed that deep vein thrombosis was five times more proneto occur in the left leg. Risk factors for MTS are Female gender, especially those who are postpartum,multiparous, or using oral contraceptives.Clinical presentations of symptomatic MTS include, acuteextremity pain and swelling, venous claudication, or chronic development of symptoms/signs of venousinsufficiency. The diagnosis of May-Thurner Syndrome is based on the clinical presentation of left lowerextremity swelling and pain in association with radiologic evidence of compression. Doppler ultrasoundwill identify if there is a DVT is present in the iliac vessels, but is unable to visualize iliac vein compressionand spurs.In the absence of DVT and for patients with only mild symptoms of left leg swelling or pain,conservative measures of prevention are used, specifically, compression stockings. These are also used if theseverity of MTS requires more aggressive invasive interventions.
