Background Endovascular stent-grafting is widely used to treat thoracic aortic dissection.However,little information is available regarding outcome following simultaneous exclusion of multiple tears.This report details eight years of experience using simultaneous multi-tear exclusion for treatment of Stanford type B thoracic aortic dissection resulting in successful aortic remodeling without adverse events.Methods From September 1998 to January 2006,29 type B thoracic aortic dissection patients(24 men,5 women;27 chronic,2 acute;mean age 58 years,range 45-77 years)were treated by simultaneous multi-tear exclusion in our center.Magnetic resonance angiography was used as the preoperative evaluation method.Different kinds of stent-grafts were used.The patients were followed up with contrast-enhanced spiral computed tomography at 6 months postoperatively and yearly thereafter.Results Twenty-nine surgeries were completed successfully using at least 2 stent-grafts per patient(range:2-6,mean:2.7).No major procedure-related complications,such as rupture,paraplegia,aortic branch ischemia or cerebral infarction,were observed.During follow-up,favorable remodeling of the aorta was observed.Conclusions The mid-term result of thoracic aortic dissection with simultaneous multi-tear exclusion was satisfactory.With the improvement of stent-grafts,simultaneous multi-tear exclusion should find wider application and become an optimal strategy for thoracic aortic dissection.
