摘要 目的探讨超声造影技术诊断胰腺移植术后并发症的临床价值。方法对86例移植胰腺行超声造影检查,观察造影剂灌注过程,绘制时间-强度曲线(time—intensitycurve,TIC)。超声造影结果与增强CT、MRI及病理结果进行对照。结果86例患者中血栓形成11例,排异反应13例,胰腺炎13例。超声造影表现:①正常移植胰腺血管及实质灌注均匀,TIC呈正偏态分布;②血栓形成:栓塞血管无造影剂灌注,实质内无增强或不均匀低增强;③排异反应:胰腺实质灌注缓慢,峰值减低,TIC上升及下降减慢,曲线峰圆顿;④移植胰腺炎:胰腺实质灌注不均匀,可见局限性低增强区,造影剂退出较缓慢,TIC上升减慢,峰值减低。结论超声造影技术能够连续观察移植胰腺血管及实质的灌注,并得出组织灌注参数,是明确诊断移植胰腺并发症的有效方法。 Objective To investigate the clinical value of contrast-enhanced ultrasound (CEUS) in the diagnosis of postoperative complications after pancreas transplantation. Methods Eighty-six post pancreas- transplantation patients were examined by CEUS to observe the perfusion of contrast agent, plot time- intensity curve (TIC), and compare to the results of enhanced CT, MRI and pathology. Results Eleven cases of thrombosis, 13 cases of rejection and 13 cases of pancreatitis were observed among 86 patients. Result from CEUS showed that : (1) Distribution of normal pancreatic grafts vascular and parenchyma was even,TIC follows positive skewed distribution. (2)Thrombosis.. there was no perfusion in the embolic vessels and no enhancement or low uneven enhancement in the parenchyma. (3) Rejection: perfusion of the parenchyma was slow, peak value was decreased, rising and falling slope of the TIC was reduced with blunt peak. (4)Pancreatitis:perfusion of the parenchyma was uneven, the regional low enhanced area was visible, clear of the contrast agent was relatively slow, rising slope of TIC was reduced and the peak value was decreased. Conclusions CEUS can monitor the perfusion of the pancreatic grafts vascular and parenchyma, and get useful perfusion parameters. It has been proven as an effective method to definitely diagnose postoperative complications after pancreas transplantation.
