BACKGROUND Percutaneous ultrasound (US)-guided fine-needle aspiration (FNA) of adrenal gland lesions is controversial in veterinary medicine. OBJECTIVE To evaluate the frequency and radiologists' perception of the risk of the procedure as well as determining the incidence of complications. METHODS Retrospective study. A first survey was submitted by e-mail to all board-certified radiologists of the American College of Veterinary Radiology (ACVR) and European College of Veterinary Diagnostic Imaging (ECVDI). A second survey was sent to radiologists who declared having performed the procedure at least once in their career (observational cross-sectional case study). RESULTS The first survey was sent to 977 diplomates and answered by 138. Of 138 diplomates, 40 currently performed the procedure and 98 did not; 44 of the 98 gave the hypertensive crisis risk in pheochromocytoma as a reason. To the second survey, 12 of 65 responded positively; 50 dogs with 58 lesions were recruited, including 23 pheochromocytomas. Complications were reported in 4 of 50 dogs; 3 hemorrhages (1 mild and 1 moderate) and 1 death from acute respiratory distress syndrome (possibly related to laryngeal paralysis). No hypertensive crisis was reported. There was no relationship between the method of FNA/type of needle used and occurrence of complications. Based on the recollection of these 65 radiologists, who performed approximately 200 FNA of adrenal lesions, a death rate of approximately 1% was estimated. CONCLUSIONS AND CLINICAL IMPORTANCE Percutaneous US-guided FNA of adrenal lesions can be considered a minimally risky procedure, despite the negative perception by radiologists.

犬肾上腺病变的经皮超声引导下细针穿刺抽吸的安全性：放射科医生对手术的理解以及50例病例的介绍。

背景技术经皮超声（US）引导的肾上腺病变的细针抽吸术（FNA）在兽医学中引起争议。目的评估频率和放射科医生对手术风险的认识以及确定并发症的发生率。方法回顾性研究。通过电子邮件向美国兽医放射学院（ACVR）和欧洲兽医诊断成像学院（ECVDI）的所有经过董事会认证的放射科医生提交了第一份调查报告。已向放射科医生发送了第二次调查，他们声称在其职业生涯中至少执行过一次该程序（观察性横断面案例研究）。结果第一次调查被发送给977位外交官，并得到138位答复。在138位外交官中，目前有40位执行了程序，而98位没有执行。98人中有44人将嗜铬细胞瘤的高血压危机风险作为原因。对第二项调查，65人中有12人正面回应；招募了50只具有58个病变的狗，其中包括23个嗜铬细胞瘤。据报道50只狗中有4只并发症。急性呼吸窘迫综合征（可能与喉麻痹有关）有3例出血（1例轻度和1例中度）和1例死亡。没有高血压危机的报道。FNA /使用的针头类型与并发症的发生之间没有关系。根据对这65位放射科医生的回忆，他们进行了约200 FNA的肾上腺病变，估计死亡率约为1％。结论和临床意义经皮超声引导下的肾上腺病变FNA可被认为是风险最小的手术，
