| To investigate the influence of endovascular graft exclusion(EVGE) by comparing the change of the function of heart ,liver and kidney before and after the EVGE of thoracic aortic dissection (TAD, Stanford B).Methods: Computed tomography angiography (CTA), magnetic resonance imaging (MRA)or digital subtraction angiography (DSA) were used as preoperative evaluation methods of thoracic aortic dissection aneurysm. According to the specific situation of patients, the suitable stent-grafts were selected. The stent-grafts were inserted from the femoral artery to exclude the tear of dissection of 12 cases, and all operations were performed by general anesthesia under DSA guidance. The function of heart, liver and kidney was measured before and after operation by using the automatic apparatus of serum biochemical analysis and echocardiography. Results.1. Kidney function measurement: There was no significant difference between the parameters of creatinine (Cr) and blood urea (BU) before and 48-72 hours after operation. Cr and BU significantly decreased one month after operation (P< 0. 05).There was a certain improve on the function of heart.2. Liver function measurement. 48-72 hours after operation, the serum contents of total protein, albumin, globulin decreased significantly and connect bilirubin , recovering the level of before operation one month after operation, increased significantly compared with those before operation. There was no significant change in the total bilirubin, unconnect bilirubin , ALT, AST, pre-and post operation. 3. Heart function measurement: EF increased significantly 24-48 hours after operation3compared with that of preoperation. No difference in peak of E and E/A24-48 hours after operation. Peak of E and E/A increased three months after operation too. Conclusion: EVGE has minimal influence on the function of heart, liver and kidney, and is a microinvasive theropy to treat TAD(Stanford B) with elder advanced and organ dyefunction.
