To demonstrate the spectral and color Doppler ultrasonography (US) findings that would indicate vascular complications after liver transplantation and to report our single center results of vascular complications detected in liver transplant recipients.
Our study was consisted of 326 patients who underwent liver transplantation procedures between November 1997 and May 2004. The records of all patients were reviewed retrospectively for the details of each patient's post-transplant Doppler US examinations, visceral angiographic examinations, and/or surgical procedures. Doppler US findings were correlated with angiographic results or surgery. Sensitivity and specificity of Doppler US parameters for the diagnosis of vascular complications of the hepatic artery, portal vein, and hepatic veins were calculated.
Vascular complications occurred in 47 patients (14%). Eight instances of vascular complications were detected intraoperatively by Doppler US at the time of transplantation. For hepatic artery complications, use of a Doppler US criteria resulted in a sensitivity and a specificity of 92% and 97%, respectively. Doppler US parameters also resulted in a sensitivity and a specificity of 100% in detecting portal vein complications, and resulted in a sensitivity of 99% and a specificity of 100% in detecting hepatic vein complications.
Although it is clear that Doppler US evaluation is an effective choice for diagnosing vascular complications after liver transplantation, we also observed that Doppler US examination plays an important role in detecting vascular complications intraoperatively and improving the patient's chance for a successful outcome.
阐述能提示肝移植术后血管并发症的频谱及彩色多普勒超声（US）表现，并报告我们单中心在肝移植受者中检测到的血管并发症结果。
我们的研究纳入了1997年11月至2004年5月期间接受肝移植手术的326例患者。回顾性分析所有患者的记录，以获取每位患者移植后多普勒超声检查、内脏血管造影检查和/或外科手术的详细信息。将多普勒超声检查结果与血管造影结果或手术情况进行关联。计算多普勒超声参数对肝动脉、门静脉和肝静脉血管并发症诊断的敏感性和特异性。
47例患者（14%）发生了血管并发症。8例血管并发症在移植时通过术中多普勒超声检测到。对于肝动脉并发症，采用多普勒超声标准的敏感性和特异性分别为92%和97%。多普勒超声参数在检测门静脉并发症时的敏感性和特异性也均为100%，在检测肝静脉并发症时的敏感性为99%，特异性为100%。
虽然很明显多普勒超声评估是诊断肝移植术后血管并发症的有效选择，但我们也观察到多普勒超声检查在术中检测血管并发症及提高患者成功预后几率方面发挥着重要作用。
