BACKGROUND:

Uterine fibroids are the most common benign tumor in premenopausal women. Most of them do not generate symptoms; however, they can produce serious systemic problems due to the compression of vital structures.

CLINICAL CASE:

A 42-year-old woman, Nuligest, anemia secondary to heavy menstrual bleeding due to myomatous uterus. She consulted for dyspnea of great efforts and progressive asthenia, chest pain in left hemithorax of pleuritic-mechanical profile and palpitations. Blood pressure 128/47. Heart rate 133, O2 Saturation 92%. Non-painful mass in hypogastrium. Not edema or signs of deep vein thrombosis. In the complementary explorations we found: D-Dimer 7455, Electrocardiogram: Sinus tachycardia at 125 bpm. Right bundle hemiblock, Computed angiotomography: Acute bilateral pulmonary thromboembolism Doppler lower extremities: external iliac femoral veins and thrombus-free popliteal, probable compression of the iliac veins by myoma, TC: Polimyomatous uterus, in anteversion, of 200 mm. Compression of inferior cava venous in iliac prebifurcation zone with partial thrombosis of right iliac venous. We Placed a lower vena cava filter with a diagnosis of secondary pulmonary thromboembolism due to compression by a enormous uterine fibroid. A hysterectomy and bilateral salpingectomy by laparotomic was performed. Pathological anatomy: uterus of 1900 g, 200 x 180 x 110 mm with multiple subserous and intramural nodules. At 5 months, the patient is asymptomatic.

CONCLUSIONS:

Large myomas (1000 g) should be considered a risk factor for venous thromboembolism due to external compression of the iliac veins.
