床旁彩色多普勒超声在经皮肾镜碎石取石术后肾假性动脉瘤出血中的诊断价值

目的探讨床旁彩色多普勒超声对经皮肾镜碎石取石术（PCNL）术后并发肾假性动脉瘤出血的临床应用价值。方法对2017年11月~2019年11月在南方医院采用介入栓塞治疗的9例PCNL术后并发肾出血患者的行床旁彩色多普勒超声检查、临床资料、数字减影血管造影检查及治疗效果进行回顾性分析。结果9例行肾动脉栓塞术治愈的患者（造影结果详细列出：单纯动脉损伤5例，假性动脉瘤4例，动静脉瘘0例），动脉栓塞前均行床边彩超检查，其中床旁彩超诊断出4例肾假性动脉瘤，最终经肾动脉造影确诊。结论床旁彩色多普勒超声，对PCNL术后继发肾假性动脉瘤的诊断有较大的优越性和临床价值。

Diagnostic value of bedside color doppler ultrasonography in renal pseudoaneurysm hemorrhage after percutaneous nephrolithotripsy

ObjectiveTo investigate the clinical value of bedside color doppler ultrasound in the diagnosis of renal pseudoaneurysm hemorrhage after percutaneous nephrolithotripsy (PCNL).MethodsNine patients with renal hemorrhage after PCNL treated by interventional embolization in Southern Hospital from November 2017 to November 2019 were enrolled. The bedside color doppler ultrasonography, clinical data and digital subtraction angiography were analyzed retrospectively.ResultsAmong 9 patients, 5 cases were finally diagnosed with arterial injury, 4 cases with pseudoaneurysm and no cases of arteriovenous fistula. All participants were examined by bedside color doppler ultrasound before arterial embolization. Four cases of renal pseudoaneurysm were initially diagnosed by bedside color Doppler Ultrasound and finally confirmed by renal arteriography.ConclusionBedside color doppler ultrasound. It has great superiority and clinical value in the diagnosis of renal pseudoaneurysm.
