Angioplastia transluminal coronariana em portador de púrpura trombocitopênica idiopática / Percutaneous transluminal coronary angioplasty in a patient with idiopathic thrombocytopenic purpura

A associação entre a doença arterial coronariana e a púrpura trombocitopênica é rara e implica em algumas dificuldades quando a revascularização se faz necessária. Relatamos um caso dessa associação, com importante comprometimento coronariano, tratado percutaneamente com o implante de stent.

Uso de stents sequenciais para o tratamento de dissecçäo helicoidal de coronária direita / Use of tandem stents for treatment of helicoidal dissection of the right coronary artery

Coronary dissection occurs frequently and in several degrees during coronary angioplasty, which is one of the mechanisms for increasing the lumen diameter of a vessel. However the length of the dissection may affect the procedure, becoming the most frequent cause of total occlusion after coronary angioplasty. We report here a case of extensive dissection that occurred during the coronary angioplasty of a focused lesion, which we treated with two long stents.
