Dissecção aguda de aorta ascendente e de tronco de coronária esquerda durante implante eletivo de stents coronários / Acute aortic and left main coronary dissection during elective coronary stenting

RESUMO

Paciente com angina pós-infarto, associada a lesões graves, em artérias circunflexa e marginal esquerda. Foi submetida a angioplastia com implante de stents, mas apresentou grave dissecção do tronco de coronária esquerda (TCE), que se estendeu para o segmento ascendente da aorta, evoluindo com hipotensão, parada cardiorrespiratória e posterior instabilidade hemodinâmica. Houve resolução imediata do quadro clínico com implante de stent no TCE.

ABSTRACT

Patient with post-infarction angina associated to severe lesions in the left circumflex artery and obtuse marginal branch was submitted to angioplasty with stenting, but developed a left main coronary artery (LMCA) dissection expanding to the ascending aorta, complicated with hypotension and cardiorespiratory arrest (CRA). She was successfully resuscitated but further hemodynamic instability developed and was resolved with LMCA stenting.
