| 目的 分析经肾静脉先天性部分型肝外门体静脉分流（CPEPSVRV）的MSCT和超声表现。方法 回顾性分析我院11例CPEPSVRV患者（病变组）和20例对照（对照组）的影像学资料，对两组患者均行MSCT增强扫描，病变组进行超声检查。采用两独立样本Mann-Whitney U检验比较两组门静脉主干、左右分支及肝固有动脉管径。结果 病变组增强MSCT均显示门和（或）脾静脉与左肾静脉间粗细不等单一分流血管，其中门-肾静脉分流2例，门脾-肾静脉分流1例，脾-肾静脉分流8例；11例均伴门静脉及其分支不同程度发育细小，其中1例同时合并门静脉右支缺如；肝总动脉及肝固有动脉均有不同程度扩张、增粗。MPR、MIP和VR可立体显示分流血管起始、走行及终止位置。超声检查均显示门静脉和（或）脾静脉血经分流血管向肾静脉分流。两组门静脉主干、左右分支及肝固有动脉管径差异均有统计学意义（P均<0.05）。结论 CPEPSVRV影像学表现具有特征性。MSCT增强扫描结合超声检查可清晰显示分流血管、分流方向及伴发病变。 |

| Objective To analyze the MSCT and ultrasonographic features of the congenital partial extrahepatic portosystemic shunt via renal vein (CPEPSVRV).Methods The imaging data of 11 patients (study group) and 20 cases (control group) with enhanced CT (both groups) and ultrasonography (study group) scan were reviewed. The data of the diameters of the portal vein, its right and left branches, proper hepatic artery were analyzed with Mann-Whitney U.Results Enhanced MSCT of 11 cases demonstrated that there was only one shunt vessel with the various diameters between portal and (or) splenic vein and the left renal vein, including two cases with portorenal shunt, one case with portosplenic renal shunt and eight cases with splenorenal shunt. All of 11 cases were associated with dysplasia of portal veins and their branches, one of them was with the absence of the right branch of portal vein. The common and proper hepatic arteries dialated to some degrees. MPR, MIP and VR could display the course, beginnings and ends of the extrahepatic portosystemic shunt via renal vein three-dimensionally. Ultrasonography showed the counter flow between potal and (or) splenic veins and renal veins. The diameters of the portal vein, its right and left branches and proper hepatic arteries between both groups had statistical differences (all P<0.05).Conclusion The imaging appearances of CPEPSVRV have some characteristics. Enhanced MSCT scan combining with ultrasonography can clearly demonstrate shunt vessel, shunt direction and associated lesions. |
