多时相增强CT对肾静脉主干血栓的诊断

Multi-temporal enhanced CT on renal vein thrombosis diagnosis

目的探讨和研究多时相增强CT对肾静脉主干血栓的诊断价值。方法选取我院近年来收治的13例典型肾静脉血栓患者的CT表现进行回顾性分析。结果患者均不同程度表现出患侧肾脏体积明显增大的现象,但相较对侧正常肾脏而言并无明显形态改变,肾实质密度降低且肾蒂增粗。动态增强的CT检查结果显示,本组患者中均存在明显的肾静脉血栓充盈缺损的影像,包括3例患者存在下腔静脉明显血栓影,位置处在肾静脉的入下腔静脉部位。此检测结果与肾静脉血管造影的检查结果相符合。结论多时相增强CT对肾静脉主干血栓的诊断准确性好,具有较高的临床应用价值。

Objective To explore and study the value of multi-temporal enhanced CT in diagnosis of the main renal vein thrombosis. Methods For removal of treated in our hospital 13 cases of renal vein thrombosis in patients with CT were retrospectively analyzed. Results The patients had varying degrees of the demonstrated ipsilateral kidney volume was significantly increased compared with the contralateral normal kidneys, but there was no obvious morphological change, renal parenchymal density decrease and renal pedicle thickening. Dynamic enhanced CT examination showed that in the group, there was significant renal vein thrombosis filling defect image, including 3 patients with inferior vena cava thrombosis exist obvious artifact, location in the renal vein into the inferior vena cava site. The testing results and the renal vein angiography findings was consistent. Conclusion The muhi-temporal enhanced CT in diagnosis of the main renal vein thrombosis has good accuracy, and high value in clinical application.
