光镜观察了２９例肾动脉狭窄标本。１例（３．４％）为动脉粥样硬化，２例（６．９％）为纤维肌性结构不良，２６例（８９．７％）为大动脉炎。结果显示，我国肾动脉狭窄的原因主要是大动脉炎。外科手术治疗肾血管性高血压时，动脉（肾动脉、髂内动脉等）的病理活检对术后治疗方案的选择是重要的。
Light microscopic observation of 29 cases of renal artery stenosis. One case (3.4%) had atherosclerosis, two (6.9%) had fibromuscular structural defects and 26 (89.7%) had arteritis. The results show that the main cause of renal artery stenosis in our country is aortitis. Surgical biopsy of the arteries (renal arteries, internal iliac arteries, etc.) is important for the selection of postoperative management options for the treatment of renovascular hypertension.
