The objectives of this retrospective study were to determine the technical success, safety, and long-term results of primary stent implantation in infrarenal aortic stenosis.
A total of eight atherosclerotic stenoses and one occlusion of the infrarenal aorta (ie, midaortic syndrome) were treated with endoluminal stent placement after balloon angioplasty. Aortoiliac lesions were excluded. Technical success and patency were assessed.
Primary technical success in percutaneous transluminal angioplasty and subsequent stent placement was achieved in all patients. No complications occurred, and no morbidity was encountered. Primary clinical patency rates were 100% on all follow-up examinations. Long-term results with a mean follow-up of 110 months (range, 99-117 months) were recorded in seven patients; one patient had died and one was lost to follow-up.
In view of the excellent initial results and promising long-term follow-up data in a small series, stent placement after predilation in properly selected patients with isolated infrarenal aortic stenosis appears to be a promising, durable treatment. It should be considered as a primary method of treatment.
本回顾性研究的目的是确定肾下腹主动脉狭窄患者一期支架植入术的技术成功率、安全性和长期疗效。
对8例动脉粥样硬化性狭窄和1例肾下腹主动脉闭塞（即中段主动脉综合征）患者在球囊血管成形术后行腔内支架置入术治疗。排除腹主动脉髂动脉病变。评估技术成功率和通畅情况。
所有患者在经皮腔内血管成形术及随后的支架置入术中均取得了一期技术成功。未发生并发症，也未出现发病率。在所有随访检查中，一期临床通畅率均为100%。7例患者记录了平均随访110个月（范围99 - 117个月）的长期疗效；1例患者死亡，1例失访。
鉴于在一小系列病例中取得的出色初始结果和有前景的长期随访数据，对于适当选择的孤立性肾下腹主动脉狭窄患者，预扩张后支架置入术似乎是一种有前景的、持久的治疗方法。应将其视为主要治疗方法。
