医源性肾内血管损伤的介入治疗探讨

目的探讨医源性肾血管的损伤，介入治疗的必要性及安全性。方法对11例因医源性肾脏穿刺后引起的血尿患者行选择性肾动脉造影或超选择性肾内动脉造影，确诊为肾内型动静脉瘘或肾动脉破裂．采用一般钢圈或神经介入专用微钢圈进行精确栓塞封闭瘘口或破裂口。结果血管造影提示11例患者均为肾内型动静脉瘘或肾动脉破裂，累及肾中极动脉或亚段分枝，治疗均一次性成功栓塞瘘口、裂口。术后患者的出血、失血症状当即得到控制，肉眼血尿或血性引流液消失，心脏负荷过度症状消失。随诊1～30个月，所有病例均无复发。结论介入治疗医源性肾内型血管损伤所致动静脉瘘或肾动脉破裂，是一项安全、有效并最大限度被患者接受的方法。

Interventional therapy in iatrogenic renal vascular injuries

Objective To evaluate the necessity and security of interventional therapy in patients with iatrogenic renal injuries.Methods 11 cases with iatrogenic renal vascular injuries were treated by superselective renal arterial embolization.Results Angiography suggested inner-renal arteriovenous fistula or renal artery break,involved mid-pole and sub-section of kidney.One-off success received in all treatment.No recurrence was found in all cases after follow-up of 1-30 months.Conclusion Superselective renal arteri...
