Systemic thrombolysis with tenecteplase was effective and safe in a pregnant woman with high-risk acute pulmonary embolism.
Supports tenecteplase consideration in pregnant high-risk PE; hypothesis-generating and should not yet change practice.
We describe the case of a 37-year-old pregnant woman who presented at 29 weeks of gestation with syncope and shortness of breath caused by pulmonary embolism. Due to persistent hypotension thrombolytic therapy with tenecteplase was administered and the clinical and hemodynamic response was excellent, with no maternal or fetal hemorrhagic complications. The clinical presentation of pulmonary embolism is sometimes camouflaged by the physiological changes that occur in pregnancy and diagnosis is often delayed by reluctance to expose the fetus to ionizing radiation. Systemic thrombolysis is considered a high-risk treatment in pregnancy and very few women have received it. However, the complication rates of thrombolytic therapy are acceptable in the light of the underlying disease. Grávida de 37 anos de idade com 29 semanas de idade gestacional recorre ao serviço de urgência por síncope e dispneia causadas por tromboembolismo pulmonar com repercussão hemodinâmica. Por hipotensão persistente foi-lhe administrada terapêutica trombolítica com tenecteplase com excelente resposta hemodinâmica e clínica, sem intercorrências hemorrágicas maternas ou fetais. A apresentação clínica do tromboembolismo pulmonar é por vezes camuflada pelas transformações fisiológicas que ocorrem na gravidez e o diagnóstico é muitas vezes atrasado pela relutância em expor o feto a radiação ionizante. A trombólise é um tratamento de alto risco na grávida e há poucos casos descritos da sua utilização; porém, as taxas de complicações com a terapia trombolítica são aceitáveis em relação à doença subjacente.
