Objective : to investigate the effect of pumpless portosystemic bypass in clinical piggyback liver transplantation. methods : after catheterized inferior mesenteric vein, the silastic catheter ( filled with heparin saline ) was connected with the catheterized tube of internal jugular vein or subclavian vein in four piggyback liver transplantation patients. the channel was opened after the portal vein was occluded. the portal vein blood poured into the superior vena cava through the pumpless channel. the changes of mesenteric congestion, portal vein pressure, blood pressure and pulse were observed. results : during the occlusion of portal vein, the portal vein pressure was increased greatly, the intestine was congested and swelled obviously and the blood pressure and pulse fluctuated gently. after the pumpless bypass opened, intestinal congestion and swell were abated markedly, the portal pressure, blood pressure and pulse gradually returned to normal range. conclusions : pumpless portosystemic bypass shows a great effect on clinical piggyback liver transplantation. it is a feasible and economical method
目的探討背駝式原位肝移植術中採用體外門-體靜脈無泵轉
流的臨床效果.方法4例行背駝式原位肝移植患者,腸系膜下靜脈屬支插管經體外硅膠管(充滿肝素鹽水)與頸內靜脈或鎖骨下靜脈插管相接,在阻斷門靜脈后
開通腸系膜下靜脈插管,門靜脈血從體外無泵轉
流管
流入上腔靜脈,觀察轉
流前後腸道瘀血、門靜脈壓、血壓、脈搏等變化情況.結果門靜脈阻斷后腸道明顯瘀血、腫脹,門靜脈壓力明顯升高,血壓、脈搏有不同程度的波動,無泵門靜脈轉
流開放后,腸道瘀血、腫脹明顯好轉,門靜脈壓力逐漸恢復正常水平,血壓、脈搏恢復正常.結論背駝式原位肝移植術中體外門-體靜脈無泵
流具有方便、經濟、實用等優點,具有良好的臨床效果
