Some authors have proposed the use of coronary stenting as a good therapeutic strategy for post angioplasty acute coronary dissection. We present our experience with the Palmaz-Schatz stent for the treatment of acute coronary dissection after percutaneous coronary angioplasty. Twenty five stents were deployed in nineteen patients with occlusion (7) or threatened occlusion (12). Eleven patients (58%) had multivessel disease, seven (37%) unestable angina and six (32%) previous myocardial infarction. The attempted lesion was type A in four patients (21%), type B in thirteen (68%) and type C in two (11%) according to the American College of Cardiology/American Heart Association classification. To cover the dissection was necessary to deploy three stents in two patients, and two stents in two more. The other fifteen patients received one stent each. In eighteen patients (95%) the stent deployment was accomplished with immediate angiographic success. Twelve stents were deployed in the right coronary artery, eight in the left anterior descending and five in the circumflex. In sixteen patients (84%) the stent successfully solved the occlusion or threatened occlusion reassuming a normal coronary flow. There were 10 complications in six patients: one death (5%), 3 cases of emergency coronary artery bypass graft (16%), 2 acute myocardial infarction (11%), 2 hemorrhagic complications (11%) and 2 cases of subacute thrombosis of the stent (11%). The Palmaz-Schatz stent seems to be a useful tool for the management of acute coronary dissection with a fair number of complications. The results obtained during hospitalization are maintained with a more than acceptable restenosis rate.
