【摘要】 目的探讨肾特发性动静脉瘘的影像学特征、介入栓塞治疗方法和疗效。方法收治4例肾动脉CTA及肾动脉造影明确诊断为肾特发性动静脉瘘患者,采用弹簧圈、明胶海绵颗粒对病变血管进行选择性动脉栓塞,术后随访观察疗效。结果介入栓塞术后,肾动脉CTA及肾动脉造影检查发现4例患者畸形血管团及动静脉分流现象均消失,相应肾脏大部分肾实质显示良好,血压、肾功能检查与术前均无明显改变,后期随访无血尿病例。结论肾动脉CTA及肾动脉造影检查可全面准确诊断肾特发性动静脉瘘,并为介入栓塞治疗提供重要参考依据;介入栓塞治疗肾特发性动静脉瘘具有微创、疗效确切、安全、并发症少的特点,并可最大限度保留患侧肾功能。更多还原

【Abstract】 Objective To explore the imaging features of idiopathic renal arteriovenous fistula and to discuss its interventional embolotherapy. Methods A total of 4 cases with CTA-and angiography-proved idiopathic renal arteriovenous fistula were enrolled in this study. Selective renal artery embolization with spring coils and Gelfoam particles was carried out in all the 4 patients. All the patients were followed up to check the results. Results After interventional embolotherapy, the abnormal vascular mass and the venous shunting disappeared completely in all the 4 patients. Most renal parenchyma was well visualized on angiography. The blood pressure and renal function showed no obvious changes after the treatment. No hematuresis occurred during follow-up period. Conclusion Both renal CTA and selective renal arteriography can provide correct diagnosis of idiopathic renal arteriovenous fistula, providing important information for interventional embolotherapy. For the treatment of idiopathic renal arteriovenous fistula, interventional embolotherapy is minimally-invasive and safe with reliable effect and fewer complications, besides, this technique can reserve the renal function to the greatest possible advantage.更多还原
