Abstract
Arteriovenous fistula is a well-known but rarely diagnosed complication of percutaneous renal biopsy. On Doppler sonography, these fistulae are characterized by a region of high velocity shifts and random color assignment due to vibrating interfaces in the perivascular tissue. Most of them resolve spontaneously, while larger symptomatic ones need intervention.
摘要
动静脉瘘是经皮肾活检一种众所周知但很少被诊断出的并发症。在多普勒超声检查中，这些瘘的特征是由于血管周围组织中的振动界面而出现高速血流偏移区域和随机的颜色分布。大多数瘘会自行消退，而较大的有症状的瘘则需要干预。
