Late portal vein thrombosis (PVT) can be extremely well tolerated, although portal hypertension and other consequences of the long-term deprivation of portal inflow to the graft may be hazardous, especially in young children. Recently, the "Rex shunt" has been used successfully to treat these patients. We now report the initial experience with this novel technique.
A 3-year-old girl with PVT at 7 months after whole organ cadaveric liver transplant displayed portal hypertension with an episode of gastrointestinal bleeding, requiring a mesenteric-portal surgical shunt ("Rex shunt") using a left internal jugular vein autograft.
Upon current follow-up of 6 months, postoperative Doppler ultrasound confirmed shunt patency. Endoscopic status was significantly improved after surgery with resolution of portal hypertension. There was no recurrence of bleeding.
The mesenteric-portal shunt ("Rex shunt"), using a left internal jugular vein autograft, should be considered for children with late PVT after liver transplantation. Although this is an initial experience, we may conclude that this technique is feasible, with great potential benefits and low risks for these patients.
晚期门静脉血栓形成(PVT)的耐受性可能非常好,尽管门静脉高压以及长期移植肝门静脉血流阻断的其他后果可能是危险的,尤其是在幼儿中。最近,“雷克斯分流术”已成功用于治疗这些患者。我们现在报告这项新技术的初步经验。
一名3岁女童在全器官尸体肝移植术后7个月发生PVT,出现门静脉高压并伴有一次胃肠道出血,需要使用左颈内静脉自体移植物进行肠系膜-门静脉手术分流(“雷克斯分流术”)。
在目前6个月的随访中,术后多普勒超声证实分流管通畅。手术后内镜检查情况显著改善,门静脉高压得到缓解。出血未复发。
对于肝移植术后晚期PVT患儿,应考虑使用左颈内静脉自体移植物进行肠系膜-门静脉分流(“雷克斯分流术”)。尽管这是初步经验,但我们可以得出结论,该技术是可行的,对这些患者具有巨大的潜在益处且风险较低。
