The rate of bleeding complications related to percutaneous native renal biopsy is low, and pseudoaneurysms of the extrarenal arteries are rare. There have been a few reports of extrarenal artery injuries related to renal biopsy; however, to the best of our knowledge, there have not been any reports of injuries to the ileocolic artery or multiple injuries to extrarenal arteries. Herein, we report the case of an 87-year-old man who developed multiple vascular injuries: an arteriovenous fistula at the lower pole of the right kidney, pseudoaneurysms of the second lumbar artery, and an ileocolic artery 19 days after renal biopsy. Although identifying an ileocolic artery pseudoaneurysm was slightly delayed due to its rarity, all vascular injuries were successfully embolized with microcoils.
经皮穿刺肾活检相关的出血并发症发生率较低，肾外动脉假性动脉瘤罕见。有少数关于肾活检相关肾外动脉损伤的报道；然而，据我们所知，尚无回结肠动脉损伤或肾外动脉多处损伤的报道。在此，我们报告一例87岁男性患者，在肾活检19天后出现多处血管损伤：右肾下极动静脉瘘、第二腰动脉假性动脉瘤和回结肠动脉损伤。尽管由于回结肠动脉假性动脉瘤罕见，其识别稍有延迟，但所有血管损伤均成功用微线圈栓塞。
