目的
目的探讨磁共振血管成像在肝移植血管并发症诊断中的应用价值。
材料和方法
对13例疑似有血管并发症的肝移植受者，在大剂量(42毫升)Gd造影剂团注的动脉和静脉期，采用三维梯度回声屏气技术进行了Gd增强磁共振血管成像检查。以常规血管造影(n=11)和外科手术(n=3)为参照标准。两位放射科医生对移植肝动脉、腹主动脉、肠系膜上动脉、门静脉、肠系膜上静脉、脾静脉、肝静脉和下腔静脉(IVC)进行血栓形成或狭窄评估。
结果
常规血管造影或手术证实10例血管并发症：移植肝动脉血栓形成3例或狭窄3例，门静脉狭窄1例或闭塞2例，肝上下腔静脉狭窄1例。磁共振血管成像对10例并发症均作出正确诊断。在所评估的62支血管中，有58支(94%)的MR血管成像结果与常规血管造影或手术结果一致。有4条血管(6%)有轻微不一致。
结论
三维增强磁共振血管成像有可能使肝移植血管并发症的准确诊断成为可能。
PURPOSE
To evaluate use of gadolinium-enhanced magnetic resonance (MR) angiography in detection of vascular complications of liver transplantation.
MATERIALS AND METHODS
Thirteen liver transplant recipients suspected to have vascular complications were evaluated with gadolinium-enhanced MR angiography by using a three-dimensional spoiled gradient-echo breath-hold technique during the arterial and venous phases of a high-dose (42 mL) bolus injection of gadolinium contrast material. Conventional angiography (n = 11) and surgery (n = 3) were used as the standard of reference. The transplant hepatic artery, celiac trunk, superior mesenteric artery, portal vein, superior mesenteric vein, splenic vein, hepatic veins, and inferior vena cava (IVC) were evaluated for thrombosis or stenosis by two radiologists.
RESULTS
Ten vascular complications were identified with conventional angiography or surgery: transplant hepatic artery thrombosis (n = 3) or stenosis (n = 3), portal vein stenosis (n = 1) or occlusion (n = 2), and suprahepatic IVC stenosis (n = 1). All 10 complications were correctly diagnosed with MR angiography. There was agreement between results of MR angiography and conventional angiography or surgery in 58 of 62 vessels evaluated (94%). There was minor disagreement in four vessels (6%).
CONCLUSION
Three-dimensional gadolinium-enhanced MR angiography may have the potential to enable accurate diagnosis of vascular complications of liver transplantation.
