PURPOSE
To present a case highlighting the efficacy of stent implantation for left renal vein (LRV) entrapment, otherwise known as the nutcracker phenomenon.
CASE REPORT
A 17-year-old boy presented with a history of gross hematuria and left flank pain. Magnetic resonance angiography documented compression of the LRV between the superior mesenteric artery and aorta. A Memotherm stent was successfully placed across the LRV to restore adequate luminal flow after a Wallstent failed to adequately span the narrowed segment. Spiral CT angiography at 6 months confirmed LRV patency; the patient remains asymptomatic and free of hematuria at 12 months.
CONCLUSIONS
Endovascular stenting for the nutcracker phenomenon is safe and effective and may represent a valuable approach for lessening the morbidity of surgical procedures.
目的
介绍一例突出显示支架植入治疗左肾静脉（LRV）受压（即胡桃夹现象）疗效的病例。
病例报告
一名17岁男孩，有肉眼血尿和左侧腰痛病史。磁共振血管造影显示肠系膜上动脉与主动脉之间的左肾静脉受压。在一个Wallstent支架未能充分跨越狭窄段后，成功植入一个Memotherm支架以恢复左肾静脉的管腔血流。6个月时的螺旋CT血管造影证实左肾静脉通畅；患者在12个月时仍无症状且无血尿。
结论
血管内支架置入治疗胡桃夹现象安全有效，可能是减少手术并发症的一种有价值的方法。
