[Coronary stent implantation: a procedure for treatment of acute dissections after percutaneous transluminal coronary angioplasty].
The development of percutaneous wire-guided endoprostheses (stents) has expanded the possibilities for treating acute vascular occlusion within the field of coronary angioplasty (PTCA). A balloon-expandable Palmaz-Schatz stent was implanted in a total of 14 patients. The coronary arteries involved were the right coronary artery (seven cases), the anterior interventricular branch (five cases), and the circumflex branch (two cases). In seven cases the stent was inserted on an emergency basis to deal with treatening occlusion during PTCA, in one case of occlusion following coronary angiography, and in three cases to recanalize the infarcted vessel. Seven of these eleven patients were submitted to a follow-up angiography three months later, when none was shown to have a restenosis of more than 50%. Stent placement was followed by anticoagulation therapy comprising coumarin combined with acetylsalicylic acid. The Palmaz-Schatz stent represents an alternative to emergency bypass surgery in the treatment of acute dissection during PTCA.
