To analyze the immediate and midterm success of stenting of mesenteric arteries by a monorail technique in patients with chronic mesenteric ischemia.
In this prospective case series, 19 patients (11 male, 8 female; mean age, 62.9 +/- 10.4 y; range, 36-82 y) with 23 symptomatic stenoses of mesenteric arteries were treated with stent placement by a monorail technique in a radiologic intervention center over a period of 4.5 years. Clinical examinations and duplex sonography were used to evaluate the stents' patency and clinical success. Kaplan-Meier graphs were calculated to analyze the patency and freedom-from-symptom rate.
Initial technical success rate was 22/23 (96%). Mean follow-up was 17 months (range, 1-58 mo). Primary patency and primary clinical success rates were 82% and 78%, respectively. According to Kaplan-Meier tables, the patency rates were 96%, 87%, 76%, and 61% at 0, 1, 15, and 24 months, respectively, and the freedom-from-symptom rates were 95%, 90%, 72%, and 54% at 0, 1, 24, and 30 months, respectively. No peri-interventional complications occurred. Two patients died of cardiac failure in the hospital within 30 days after intervention; deaths were not related to the intervention.
Stent placement by a monorail technique in mesenteric arteries is an effective and safe treatment for symptomatic stenoses in patients with chronic mesenteric ischemia after a mean follow-up of 17 months.
分析采用单轨技术对慢性肠系膜缺血患者进行肠系膜动脉支架置入术的近期及中期成功率。
在这个前瞻性病例系列研究中，19例患者（11例男性，8例女性；平均年龄62.9±10.4岁；范围36 - 82岁），共23处有症状的肠系膜动脉狭窄，在4.5年的时间里于放射介入中心采用单轨技术进行支架置入治疗。通过临床检查和双功超声评估支架通畅情况及临床成功率。计算Kaplan-Meier曲线以分析通畅率和无症状率。
初始技术成功率为22/23（96%）。平均随访17个月（范围1 - 58个月）。一期通畅率和一期临床成功率分别为82%和78%。根据Kaplan-Meier表，0、1、15和24个月时的通畅率分别为96%、87%、76%和61%，0、1、24和30个月时的无症状率分别为95%、90%、72%和54%。未发生围手术期并发症。2例患者在介入治疗后30天内在医院死于心力衰竭；死亡与介入治疗无关。
平均随访17个月的结果显示，采用单轨技术对慢性肠系膜缺血患者有症状的狭窄进行肠系膜动脉支架置入术是一种有效且安全的治疗方法。
