Nutcracker syndrome is an entity resulting from left renal vein compression by the aorta and the superior mesenteric artery, which leads to symptoms of hematuria or left flank pain. The alternative option of endovascular or extravascular stenting is very appealing because of the minimal invasive procedures. Stents in the renal vein can cause fibromuscular hyperplasia, proximal migration or embolization.
A 30-year-old female was diagnosed with nutcracker syndrome for severe left flank pain. After failed conservative approach, she underwent endovascular stenting and subsequently developed recurrent symptom for stent migration one month postoperatively. She underwent successful extravascular stenting with complete symptom resolution.
The extravascular stenting is an alternative option after migration of left renal vein endovascular stenting. The computed tomographic imaging was closely correlated to therapeutic interventions and stent migration.
胡桃夹综合征是一种由主动脉和肠系膜上动脉压迫左肾静脉导致血尿或左侧腰痛症状的疾病。血管内或血管外支架置入术作为替代选择,因其微创性而极具吸引力。肾静脉内的支架可导致纤维肌性增生、近端移位或栓塞。
一名30岁女性因严重左侧腰痛被诊断为胡桃夹综合征。保守治疗失败后,她接受了血管内支架置入术,术后1个月因支架移位症状复发。她接受了成功的血管外支架置入术,症状完全缓解。
血管外支架置入术是左肾静脉血管内支架置入术后移位的一种替代选择。计算机断层扫描成像与治疗干预和支架移位密切相关。
