Establishing optimal hepatic venous outflow is the key for a successful outcome of living donor liver transplantation using a right lobe graft. The purpose of this article is to illustrate the surgical techniques of middle hepatic vein reconstruction with an interposition vein graft in living donor liver transplant recipients using a modified right lobe graft, normal postoperative Doppler sonographic findings, and various Doppler sonographic abnormalities suggestive of hepatic venous congestion.
Hepatic venous congestion after living donor liver transplantation using a right lobe graft may produce various abnormalities on Doppler sonography. In addition to allowing the patency of the middle hepatic vein tributaries and interposition vein graft to be assessed during the early postoperative period, Doppler sonography can depict the flow direction in the portal vein and in the middle hepatic vein tributaries; therefore, Doppler sonography can reveal reversal of portal flow direction in patients with acute and severe venous congestion and can show the presence of a functional intrahepatic anastomosis between the hepatic vein tributaries during the follow-up period in those with improved congestion.
建立最佳的肝静脉流出道是使用右叶移植物的活体肝移植成功的关键。本文旨在阐述在使用改良右叶移植物的活体肝移植受者中,采用静脉间置移植重建肝中静脉的手术技术、术后正常的多普勒超声检查结果以及提示肝静脉淤血的各种多普勒超声异常表现。
使用右叶移植物的活体肝移植术后肝静脉淤血可能在多普勒超声检查中产生各种异常表现。除了能在术后早期评估肝中静脉分支和静脉间置移植物的通畅情况外,多普勒超声还能描绘门静脉和肝中静脉分支内的血流方向;因此,多普勒超声可揭示急性和严重静脉淤血患者门静脉血流方向的逆转,并能在淤血改善的患者随访期间显示肝静脉分支间功能性肝内吻合的存在。
