Abstract:
Objective To explore the feasibility,effectiveness,and safety of balloon catheter-assisted total hepatic vascular exclusion.Methods We designed and manufactured an endovascular catheter with three lumens and double balloons,which can be inserted into the retrahepatic inferior vena cava through the femoral vein.The superior and inferior vena cava of the liver can be blocked by filling balloon,and the total hepatic vascular exclusion was achieved by combining with pringle method.In animal experiments,total hepatic vascular exclusion was performed by balloon catheter-assist method(experimental group)or traditional methods(control group),and the complete time was compared between the two groups.Blood flow blocking effect was observed by angiography and incision of retrahepatic inferior vena cava under direct vision.The complications were recorded.Results Total hepatic vascular exclusion was successfully completed in both groups.The completion time in the experimental group was significantly shorter than that in the control group([12.5±1.2]min vs.[35.8±4.9]min,P<0.05).CT angiography,DSA,and direct vision of blood vessels all confirmed the effectiveness of balloon catheter-assisted hepatic blood flow exclusion.No catheter displacement,balloon rupture,or air embolism occurred.Conclusion The balloon catheter-assisted hepatic total vascular exclusion is simpler and more feasible than traditional method.
