摘要 目的观察去细胞牛颈静脉带瓣管道(B JVC)重建猪右心室流出道后的血流动力学。方法应用经去细胞(B组)及未去细胞(A组)的牛颈静脉带瓣管道分别进行猪肺动脉与右心室连接,行超声心动图检测牛颈静脉带瓣管道血流动力学参数。结果重建术后3个月16头猪均存活。A组及B组牛颈静脉近端及远端吻合口口径、牛颈静脉反流量差异无统计学意义,A组近端及远端吻合口压差、跨瓣压差大于B组,差异有统计学意义(P<0.05)。结论去细胞化的牛颈静脉可能是一种更好的重建右室流道材料,但远期效果需进一步研究。 Objective To observe hemodynamic performance of aceUularized （valved bovine jugular venous conduits,BJVC） for right ventricular outflow tract reconstruction in porcine model. Methods Group A： The tanned and modified BJVC were implanted between the pulmonary artery and right ventricle in 8 pigs;Group B：the acellularized,tanned and modified BJVC were implanted between the pulmonary artery and right ventricle in another 8 pigs. The hemodynamic performance of BTVC in two groups was measured by echoeardiography. Results Those 16 pigs were alive after 3 months. The differences in the distal,proximal caliber,distal,proximal pressure gradients,and the regurgitation volume of BJVC between group A and B were not significant,but the cross-valved pressure gradient was higher in group A than that in group B significantly. Conclusion Theacellularized,tanned and modified BJVC is possibly one better kind of material of reconstructing fight ventricular outflow tract. But its long-dated effect needs more research.
