左肾静脉压迫综合征(附10例报告)

Left renal vein entrapment syndrome (report of 10 cases)

目的 提高左肾静脉压迫综合征的诊治水平。 方法 回顾性分析 10例左肾静脉压迫综合征患者的临床资料。男 9例 ,女 1例。年龄 14～ 37岁 ,平均 2 4岁。临床表现血尿 7例 ,蛋白尿2例 ,血尿合并蛋白尿 1例。彩色多普勒超声示左肾静脉扩张段直径均为受压狭窄处 3倍以上 ,9例行磁共振血管成像 (MRA)示左肾静脉受压。 结果 患者行左肾静脉内支架植入术 7例 ,肠系膜上动脉切断再吻合术 3例 ,手术均获成功。术后电话或门诊随访 1～ 5年 ,患者症状消失 ,左肾静脉无明显受压。 结论 左肾静脉压迫综合征临床表现多为非肾小球性血尿或直立性蛋白尿。多普勒超声、MRA及膀胱镜检查结合临床症状并除外其他疾病可作出诊断。一般行保守治疗随访观察 ,对有肾功能损害或有并发症者行外科手术或介入治疗。

Objective To evaluate the diagnosis and treatment of left renal vein entrapment syndrome. Methods The clinical data of 10 cases of left renal vein entrapment syndrome were retrospectively analyzed.Their mean age was 24 years (range,14-37 years).Of them 7 cases presented with non-glomerular origin hematuria;2,with orthostatic proteinuria;1 with hematuria accompanied by proteinuria.Color Doppler sonography showed that the dilated segment of the left vein was three-fold than the strictured segment in diameter,and magnetic resonance angiography (MRA) showed that the left renal vein was compressed in 9 cases. Results Stent placement across the left renal vein was performed in 7 cases.Superior mesenteric arteriectomy and replantation were performed in 3 cases.The operations were all successful.Follow-up of 1-5 years showed that the clinical symptoms were improved and urine tests were normal. Conclusions Non-glomerular hematuria or orthostatic proteinuria is frequently found in left renal vein entrapment syndrome.Left renal vein entrapment syndrome can be diagnosed by Doppler sonography,MRA and cystoscopy in the presence of hematuria or proteinuria.Generally,conservative treatment and careful follow-up are conducted in these patients.Surgical and radiologic interventional procedures are effective alternatives for those with glomerular dysfunction and complications.
