【摘要】：目的:探讨门静脉栓塞的MSCT诊断价值。方法:回顾性分析29例经临床/手术病理证实的门静脉栓塞患者的MSCT表现和临床资料,29例中门静脉血栓(PVT)13例(PVT组),门静脉瘤栓(PTT)16例(PTT组)。结果:29例栓子的部位、范围均清晰显示;13例PVT中9例继发于肝硬化门静脉高压;CT平扫呈等或稍高密度,动态增强呈不同形态、无强化的低密度充盈缺损;7例呈典型的"靶征",5例呈"线样征"。16例PTT均继发于肝癌;CT平扫表现为等或稍低密度,动态增强呈形态各异、不均匀强化的充盈缺损;PVT组与PTT组间CT强化差异具有统计学意义(P=0.000);PVT组完全阻塞3例(3/13),PTT组12例(12/16),PTT组完全阻塞率高于PVT组(P=0.040);PVT组管腔局部扩张2例(2/13),PTT组12例(12/16),PTT组管腔局部扩张高于PVT组(P=0.030);PVT组管壁局部不光整1例(1/13),PTT组14例(14/16),PTT组管壁局部不光整率高于PVT组(P=0.000)。结论:MSCT能显示门静脉栓塞的影像特征,准确判断栓子的部位、范围及性质,对该病的诊断具有重要价值。
[Abstract]:Objective: to evaluate the diagnostic value of MSCT in portal vein embolism.Methods: the MSCT findings and clinical data of 29 patients with portal vein embolism confirmed by clinical / operative pathology were retrospectively analyzed.Results the location of embolus in 29 cases of PVT showed clearly that 9 of the 13 cases of PVT were secondary to portal hypertension in cirrhosis. Ct plain scan showed equal or slightly high density, and dynamic enhancement showed different morphology.Non-enhanced low-density filling defect presented typical "target sign" in 5 cases and "linear sign" in 5 cases. All the 16 cases of PTT were secondary to CT plain scan of hepatocellular carcinoma with equal or slightly low density, and dynamic enhancement was different in shape.The local wall of the PVT group was higher than that of the PVT group (P < 0.030). The local wall of the PVT group was higher than that of the PVT group (n = 14, 14 / 16) and the local wall area was higher than that of the PVT group (P = 0.000), which was higher than that in the PVT group (n = 14).Conclusion MSCT can display the imaging features of portal vein embolism, and accurately judge the location, scope and nature of embolus, which is of great value in the diagnosis of portal vein embolism.
