Objective Patients with aortic dissection have a significant incidence of coronary artery disease. The purpose of this study is to evaluate the safety and feasibility of percutaneous coronary stent in patients who have undergone endovascular stent, and to assess the effect of anti-coagulant and anti-platelet treatment on patients’ thrombosis process. Methods From January 2005 to July 2007, 8 patients who had undergone endovascular stent-graft during the past 1 to 7 months for type B aortic dissection repair, underwent percutaneous coronary intervention (PCI) because of coexisting coronary artery disease. Anti-coagulant and anti-platelet treatments were administrated after PCI according to the standard protocol. Patients were followed up for a mean period of 23 months. Clinical and false lumen status data were collected during the follow-up. Results PCI were technically successful in all 8 patients and no severe complications such as death, paraplegia, renal failure occurred during hospitalization. Complete false lumen thrombosis was observed in 5 patients and incomplete false lumen thrombosis in the remained 3 patients at the end of follow up. There were no major complications such as death, dissection rupture or aneurysm development occurred during the follow-up period. Conclusion Our data implied that PCI can be safely performed in patients with type B aortic dissection who have undergone endovascular stent-graft, without interrupt- ing the thrombosis process.
