原位肝移植术后并发症的影像学评价

目的：对评价原位肝移植(orthotopic liver transplantation，OLT)术后并发症的影像学检查方法进行评价。方法：对OLT术后并发症的影像学检查结果进行分析，并对各类并发症的相关影像学表现加以总结。结果：B超可用作OLT术后并发症的早期筛查；彩色多谱勒超声能早期发现血管性并发症；螺旋CT和MRI对术后血管性和(或)胆管性并发症、肝实质本身异常以及肝外转移性并发症有很高的诊断价值；对排斥反应．目前影像学检查还无特征性表现。结论：影像学检查(特别是超声、螺旋CT和MRD在OLT术后各类并发症的诊断中具有重要的作用。

Imaging Evaluation of Complications of Orthotopic Liver Transplantation

Objective To introduce the imaging modalities used for the evaluation of postoperative complications of orthotopic liver transplantation (OLT) and to present the imaging findings of these complications. Methods The literatures related to the imaging methods and imaging manifestations of OLT complications were reviewed. Results Ultrasound was the initial imaging technique used for the detection of complications in the early postoperative period. Spiral CT and MRI yielded more accurate and comprehensive evaluation of postoperative complications in later stage. So far, there had been no specific imaging findings to suggest rejection reaction. The spectrum of imaging manifestations of OLT complications, such as vascular complications, biliary complications, liver parenchymal complications, and so on, were summarized and illustrated.Conclusion Imaging examination (especially ultrasound, spiral CT and MRI ) plays an important role in the evaluation of postoperative complications of OLT.
