BACKGROUND: The association of deep venous thrombosis (DVT) with uterine leiomyomata has been reported only rarely in the English-language literature. These concomitant findings occurred in a woman with no other known risk factors for development of DVT. CASE: A 49-year-old, Caucasian woman, gravida 3, para 3, with a past medical history significant for large uterine leiomyomata, menorrhagia and anemia, presented with acute edema of the left lower extremity. Doppler studies revealed compression of the left iliofemoral vein with associated thrombosis. No risk factors for DVT were identified. Intravenous heparin was initiated, with eventual preoperative placement of an inferior vena cava Greenfield filter. A total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed without complications. CONCLUSION: Large uterine leiomyomata area potential cause of lower extremity venous stasis and resulting thrombosis and can be treated with hysterectomy. (J Reprod Med 2001;46:405-407).
