摘要
目的探讨门静脉海绵样变的MDSCT表现,评价MDSCT诊断CTPV的临床价值及意义。方法回顾性分析35例经手术病理或US或DSA证实的CTPV患者MDSCT表现。结果本组35例主要表现为门静脉正常结构消失或紊乱、主干和(或)分支闭塞,肝门区门静脉或胆囊周围可见大量侧支静脉形成;动脉期17例出现肝实质灌注异常,静脉期消失。通过VR、MIP血管成像技术能更直观显示门静脉栓塞、侧支静脉情况。结论MDSCT动态增强及血管成像技术对CTPV的诊断和指导临床治疗都具有重要价值。
Objective To investigate the Multidetector spiral CT（MDSCT）feature of cavernous transformation portal vein and to evaluate the clinical value of MDSCT in diagnosing Cavernous transformation of portal vein（CTPV）.Methods The MDSCT finding in 35 patients with cavernous transformation of portal vein comfirmed by pathologically,DSA or US were retrospectively analyzed.Results The characteristic features included losing the normal structure of the portal phase and obliteration and many abnormal enhanced collateral vein around portal vein（cystic vein）.On dynamic enhanced MDSCT scans,abnormal hepatic perfusion appeared in arterial phase in 17 cases and disappeared in venous phase.MDSCTA with Maximum intensity projection（MIP）and volume rendering（VR）reconstruction accurately depicted both the tumor thrombus within the portal vein and collateral vessel of CTPV.Conclusion Dynamic enhanced MDSCT and MDSCTA are of great value for the diagnosis and treatment of CTPV.
