The computed tomographic (CT) findings in 18 patients with angiographically proved, isolated splenic vein occlusion (SVO) were retrospectively analyzed. The distribution of venous collateral vessels and the frequency of their occurrence in these patients were then compared with CT findings in 17 patients with proved portal hypertension and normal CT findings in 20 patients. Short gastric and coronary collateral vessels were seen in 61% and 83%, respectively, of patients with SVO and in 71% each in patients with portal hypertension. However, a large gastroepiploic vein was seen only in patients with SVO (11 of 18 patients [61%]). Recanalization of umbilical/paraumbilical veins was seen only in patients with portal hypertension (seven of 17 patients [41%]). Results suggest that collateral vessels in SVO often have a characteristic and distinctive appearance on abdominal CT scans.
对18例经血管造影证实为孤立性脾静脉闭塞（SVO）患者的计算机断层扫描（CT）结果进行了回顾性分析。然后将这些患者中静脉侧支血管的分布及其出现频率与17例已证实门静脉高压患者的CT结果以及20例CT结果正常患者的CT结果进行比较。SVO患者中分别有61%和83%可见胃短静脉和冠状静脉侧支血管，门静脉高压患者中各有71%可见。然而，仅在SVO患者中可见大网膜静脉（18例患者中有11例[61%]）。脐静脉/脐旁静脉再通仅见于门静脉高压患者（17例患者中有7例[41%]）。结果表明，SVO中的侧支血管在腹部CT扫描上通常具有特征性和独特的表现。
