Abstract:
Objective To evaluate the effectiveness and safety of successive interventional treatment in patients with thoracic aortic dissection and coronary heart disease by endovascular graft exclusion(EVGE)and percutaneous coronary intervention(PCI)respectively.Methods From January,2005 to July,2007,8 patients with Stanford B aortic dissection and coronary heart disease received successive EVGE and PCI in our centre.All patients were performed with EVGE 3-7 days prior to their PCI.Results The site of dissection tears were confirmed by aortic angiography which located within 0~10 mm from the exterior margin of left subclavian artery in 1 patient,11-30 mm in 4 patients and 31-50 mm in 3 patients.One patient had two tear gaps.Dissection of or distal to the renal arteries were involved in 7 patients.Talent graft(Medtronic Corporation,U.S.)was used in one patient and Aegis grafts(Microsport Medical Corporation,China)in 7 patients.Eight trunk tectorial membrane stents were used with lengths ranged from 100 to 140 mm with diameters ranged from 34 to 38 mm.Left subclavian artery was thoroughly covered by the proximal section of the graft in one patient,which resulted in a weak left radial artery pulse but with no obvious ischemic symptom of the left upper limb and brain.Procedures were technically successful in all patients and no severe complication such as death,paraplegia,and kidney insufficiency occurred after the procedure during hospitalization.Post-procedural aortography showed no leakage in 4 patients and minor leakage in 4 patients.Two patients had residual thoracic back pain which could be relieved by drugs.Coronary angiography showed that 4 patients had single-vessel disease,2 had double-vessel disease and one had triple-vessel disease.The mean stenosis rate of the target lesions was 85.6%?14.0% and the mean diameter of the reference vessels was 2.8?0.3 mm.Twelve stents were inplanted in 11 target vessels in 8 patients.The mean length of stents was 23.5?13.6 mm.The procedural success rate of PCI was 100% and no severe complication occurred.No mortality,delayed endo-leak,adverse cardiac events and repeat intervention was recorded during a mean follow-up period of 18.0?8.5 months.Conclusion It is safe and feasible to treat Stanford B aortic dissection and coronary heart disease by successive inter vention of EVGE and PCI.The effect of anticoapulation therapy after PCI on EVGE still requires further investigation.
