ABSTRACT
ObjectiveTo explore the surgical techniques and clinical experiences in treating thoracoabdominal aorta dissecting aneurysm following Sun's procedure.MethodsFrom June 2009 to May 2011,thoracoabdominal aorta replacement was performed in thirteen patients with thoracoabdominal aorta dissecting aneurysm following Sun's procedure in Beijing Anzhen Hospital.Among which,eleven were male,and two were female with a mean age 39.3 years (28 -58 years).All cases were Stanford A aortic dissection,and were underwent Sun's Procedure.The pathogeny of the dissection,ten were Marfan's syndrome,and three were hypertension.Thoracoabdominal aorta dissecting aneurysms were all Crawford type Ⅱ,with the diameter( 5.78 ± 1.00 )cm (4.0 -8.0 cm).All the procedures were performed through combined thoracoabdominal incision via the retroperitoneal approach.And thoracoabdominal aorta was replaced by a tetrafurcate graft with short-time interval circulatory arrest.24 - 30 mm tetrafurcate grafts were selected in all patients.The main graft of the tetrafurcate graft was anastomosed to the elephant truck stent graft.Visceral arteries were joined into a patch and were anastomosed to the other end of the main graft.T6 to T12 intercostal arteries were reconstructed by an 8 mm sidearm.Another 8 mm sidearm was anastomosed to the left renal artery.Both 10 mm sidearms were anastomosed to iliac arteries.Among which,seven were underwent by profound hypothermia with circulatory arrest,and six were underwent off pump with normal temperature.ResultsNo early death.Twelve patients were cured and discharged from hospital.Seven patients were underwent profound hypothermia with circulatory arrest.Among which,one patient had paraplegia,sepsis,pseudomembranous colitis,respiratory failure,and died on 102-day after operation.Another one patient had neurological dysfunction and was cured after six-day's dehydrated treatment.The UFCT showed that the tetrafurcate graft was unobstructed,no distortion,no pseudoaneurysms in all patients.The branch to intercostal arteries was obstructed in three cases,but there were no spinal cord ischemia complications.The mean duration of follow-up was (9.6 ±2.1 ) months (range,1 -24 months),with a follow-up rate of 100%.All the tetrafurcate graft were very well,no obstruction,no distortion and no pseudoaneurysms.There were no cerebral,spiral cord and abdominal viscera ischemia complications in all patients.ConclusionThoracoabdominal aorta replacement after Sun's procedure is simple,and it is helpful to reduce complications.Following Sun's procedure,using tetrafurcate graft with short-time interval circulatory arrest and off pump technique in thoracoabdominal aorta replacement is simple,and it is helpful to reduce complications.
