Synergistic effect of May-Thurner syndrome and COVID-19

May-Thurner syndrome (MTS) is also called Cockett syndrome or iliocaval syndrome is described as compression of the left iliofemoral vein by the right common iliac artery against the vertebral body. We present a rare case of MTS in a 31-year-old female in the left lower extremity complicated after COVID-19. Screening magnetic resonance imaging pelvis showed compression of left common iliac vein by right common iliac artery over L5 lumbar vertebra suggestive of MTS. Findings were confirmed by a lower limb computed tomography venogram. A high degree of clinical suspicion of COVID-19 post sequela is needed for early diagnosis in this era. © 2022 Wolters Kluwer Medknow Publications. All rights reserved.
