To determine the immediate and delayed complications of percutaneous adrenal biopsy and any relationship between biopsy methods and complications.
Medical records and radiological examinations of 83 percutaneous adrenal biopsy were reviewed. Indication for biopsy, inpatient/outpatient status, lesion size and location, imaging modality used, needle type, size, approach and number of passes, biopsy results, immediate complications, and delayed complications were recorded.
Computed tomography was used in 79 cases (95%) and ultrasound in 4 (5%). The biopsy approach was posterior in 37 cases, transhepatic in 33, transpancreatic in 9, anterior in 2, transsplenic in 1, and lateral in 1. The total complication rate was 8.4% and was slightly higher for the transhepatic approach (12%) than the posterior approach (8%). Seven complications occurred: two pneumothoraces, two pain, one perinephric hemorrhage, one subcapsular and intrahepatic hematoma, and one hepatic needle-tract metastasis. The posterior approach was complicated by the two pneumothoraces and perinephric blood; the transhepatic was used in the other four. Five of the complications occurred with 22 gauge needles.
Percutaneous adrenal biopsy is a safe procedure. Complications occurred in 7 of our patients (8.4%).
确定经皮肾上腺活检的即刻和延迟并发症，以及活检方法与并发症之间的任何关系。
回顾了83例经皮肾上腺活检的病历和影像学检查。记录活检指征、住院/门诊状态、病变大小和位置、使用的成像方式、针的类型、尺寸、进针路径和次数、活检结果、即刻并发症和延迟并发症。
79例（95%）使用计算机断层扫描，4例（5%）使用超声。活检路径为后入路37例，经肝入路33例，经胰入路9例，前入路2例，经脾入路1例，外侧入路1例。总并发症发生率为8.4%，经肝入路（12%）略高于后入路（8%）。发生了7例并发症：2例气胸、2例疼痛、1例肾周出血、1例包膜下和肝内血肿、1例肝针道转移。后入路出现2例气胸和肾周出血；另外4例采用经肝入路。5例并发症发生在使用22号针时。
经皮肾上腺活检是一种安全的操作。我们的患者中有7例（8.4%）发生了并发症。
