Orthotopic liver transplantation can be a surgically complex undertaking, with hepatic venous outflow obstruction occurring at a rate of 1%-6% due to inferior vena cava (IVC) torsion, compression, or anastomotic stenosis. In this report, we present 2 cases of immediate postoperative hepatic venous outflow obstruction in the setting of Budd-Chiari syndrome successfully treated with immediate IVC stenting. Although IVC stenting has been reported for management of long-term IVC anastomotic stenosis after orthotopic liver transplantation, use of stenting to address immediate postoperative caval outflow obstruction is less commonly described. We describe the potential utility of immediate stenting to improve outflow from the transplanted liver and highlight the value of this approach in addressing early postsurgical IVC pathology.
原位肝移植手术可能复杂，因下腔静脉（IVC）扭转、受压或吻合口狭窄，肝静脉流出道梗阻发生率为1% - 6%。在本报告中，我们呈现2例布加综合征患者术后即刻发生肝静脉流出道梗阻，通过即刻行IVC支架置入成功治疗。尽管已有报道使用IVC支架治疗原位肝移植术后长期IVC吻合口狭窄，但使用支架处理术后即刻发生的腔静脉流出道梗阻较少被描述。我们描述了即刻支架置入对改善移植肝流出道的潜在作用，并强调了该方法在处理术后早期IVC病变方面的价值。
