Outflow obstruction or stenosis of a hepatic graft is a rare but serious complication after liver transplantation, with a reported incidence of 1% to 6%. It can cause signs of portal hypertension, renal dysfunction, or lower-extremity edema depending on the level of obstruction, which may lead to patient mortality. Most reported cases show a stenosis at either the inferior vena cava (IVC) or one of the hepatic veins. Herein we have reported our experience of concurrent suprahepatic IVC and hepatic vein stenoses after orthotopic liver transplantation with related imaging findings and a successful treatment outcome. Due to the complexity of stenoses, two self-expandable metallic stents were placed simultaneously using different venous accesses.
肝移植后肝移植物流出道梗阻或狭窄是一种罕见但严重的并发症,报道的发生率为1%至6%。根据梗阻的部位,它可引起门静脉高压、肾功能不全或下肢水肿等症状,这可能导致患者死亡。大多数报道的病例显示在下腔静脉(IVC)或肝静脉之一处存在狭窄。在此,我们报告了原位肝移植术后并发肝上IVC和肝静脉狭窄的经验、相关影像学表现及成功的治疗结果。由于狭窄情况复杂,通过不同的静脉通路同时放置了两个自膨式金属支架。
