Abstract
in English, Portuguese

Pulmonary artery dissection is a fatal complication of long-standing pulmonary hypertension, manifesting as acute, stabbing chest pain, progressive dyspnea, cardiogenic shock, or sudden death. Its incidence has been underestimated, and therapeutic options are still scarce. In patients with pulmonary hypertension, new chest pain, acute chest pain, or cardiogenic shock should raise the suspicion of pulmonary artery dissection, which can result in sudden death.

A dissecção da artéria pulmonar é uma complicação fatal da hipertensão pulmonar de longa duração que se manifesta como dor torácica aguda e lancinante, dispneia progressiva, choque cardiogênico ou morte súbita. Sua incidência é subestimada, e as opções terapêuticas são ainda limitadas. O aparecimento de uma dor torácica aguda ou nova, choque cardiogênico ou morte súbita em pacientes portadores de hipertensão pulmonar deve alertar para o diagnóstico de dissecção da artéria pulmonar
