PURPOSE: To determine the effect of aortoiliac stent placement on walking ability and health-related quality of life (QOL) for elderly individuals with moderate to severe intermittent claudication. MATERIALS AND METHODS: A prospective single-center study was performed in 35 consecutive patients (46 symptomatic limbs) with intermittent claudication and aortoiliac insufficiency (mean age+/-SD, 61.1 years+/-9.5). Baseline and follow-up data to 12 months included clinical status, ankle-brachial index (ABI), exercise performance according to a standardized treadmill exercise protocol, and self-reported health-related QOL according to the Walking Impairment Questionnaire (WIQ) and the Short Form 36 (SF-36). RESULTS: Comparing baseline with 12-month data, mean ABI significantly improved from 0.64+/-0.15 to 0.89+/-0.19 (P<.01). Similarly, mean initial claudication duration improved from 1.7 minutes+/-1.0 to 4.7 minutes+/-3.3 and maximum walking duration on the treadmill test improved from a mean of 3.3 minutes+/-1.8 to 8.7 minutes+/-4.4. All WIQ subscales showed significant improvement, and the SF-36 physical component scale as well as subscales of physical functioning, bodily pain, role physical, and vitality showed significant improvement. There was no 30-day mortality. Complications in the perioperative period that required treatment were observed in three patients (9%), but surgery was not required for any complications. Importantly, urgent or emergent surgery was not required for any complication and no permanent disability related to complications occurred. CONCLUSIONS: A high technical success rate (97%) and low complication rate were observed. Exercise performance and health-related QOL results improved significantly after stent placement. Revascularization with stent placement should be strongly considered in addition to conservative management for moderate to severe claudication with aortoiliac obstruction. A randomized clinical trial would be needed to gauge the relative effectiveness of stent implantation and conservative therapy. |
