| 摘 要： | 目的 探讨16排螺旋CT(SCT)门静脉成像时胃周静脉曲张的表现特点及其规律性．并评价其在胃周静脉曲张临床处理中的价值。资料与方法 对178例疑有胃周静脉曲张的患者行上中腹部门静脉早期增强扫描．进行门静脉成像。结果共显示胃周静脉曲张64例，其中胃左静脉曲张63例；胃短静脉和胃后静脉曲张45例(31例伴发胃左静脉曲张)；脾肾或胃肾分流63例；胃网膜静脉曲张5例。结论 16排SCT门静脉成像可多方位、多角度直观显示胃周静脉曲张，效果较满意。可为选择患者、优化治疗方案及评估疗效提供客观详细的影像学依据。 |

| Abstract: | Objective To describe the 16-detector row CT manifestations of perigastric varices in portal hypertension and to discuss its role in the management of gastric varices.Materials and Methods Abdominal enhanced CT scans were performed in 178 patients suspected with gastric varices, and CT portography was done in postprocessing work station.Results On CT portography, gastric fundic varices were seen in 64 cases. Left gastric vein in 63 cases, short gastric vein and posterior gastric vein in 45 cases, 31 of which accompanied by LGV, splenorenal shunts or gastrorenal shunts (GRS) in 63 cases, gastroepiploic vein in 5 cases.Conclusion 16-detector row CT portography has excellent capability to demonstrate perigastric varices in 3D positional relationships from multiple directions by rearranging images. It is useful for selecting patients, planning procedure, and eventually evaluating the results. |
