Abstract

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.
