The mechanism of percutaneous transluminal renal angioplasty (PTRA) was studied in 18 dogs. The dogs were divided into two groups. Seven dogs were in the early group and eleven were within 1-3 weeks after PTRA. A 4/0 resorbable chronic catgut was used to ligate subtotally the renal artery to create fibromuscular dysplasia. PTRA was performed after renal artery stenosis for 6-8 weeks. The changes of ultrastructure of renal artery were studied. A contrary orientation balance hypothesis was proposed to explain the mechanism of PTRA.
对18只犬进行经皮腔内肾血管成形术（PTRA）机制的研究。犬被分为两组。7只为早期组，11只为PTRA术后1 - 3周组。使用4/0可吸收慢性肠线部分结扎肾动脉以造成纤维肌性发育异常。肾动脉狭窄6 - 8周后进行PTRA。研究肾动脉超微结构的变化。提出一种反向取向平衡假说来解释PTRA的机制。
