[Severe pulmonary thromboembolism caused by contraceptives in adolescents]. / Tromboembolismo pulmonar grave secundário ao uso de anticoncepcional em adolescente.

A 16 year-old female patient on oral contraceptive (gynera-ethynilestradiol+gestadone) for 4 months, presented with acute and severe pulmonary thromboembolism (PT), and was successfully treated with IV streptokinase. The contraceptive use was an importante risk factor for PT and the thrombolytic therapy provided early clinical improvement. Blood pressure, heart rate, and hypoxemia, along with echocardiography and pulmonary arteriography abnormalities, improved after this treatment.
