69 balloon-expandable vascular endoprostheses (Palmaz stents) were placed in 65 iliac arteries of 57 patients. The indications for stent placement were total occlusions (n = 15), restenosis after PTA (n = 13), dissections (n = 4), post-operative strictures (n = 3) or others (n = 30). The peak systolic pressure gradient dropped from 43.9 to 2.9, the mean pressure gradient to 1.9 mmHg after stent placement. This was significantly lower than conventional PTA (residual peak systolic pressure gradient: 5.8). Complications occurred in 7.7% of all interventions. 78.4% of the patients showed no limiting claudication after stent placement. Angiographic controls after 47 weeks demonstrated an average intima proliferation of 0.4 mm, not leading to significant restenosis. Cumulative patency after 16 months was 96%. Iliac stents became an effective and in certain situations indispensable adjuvant to PTA.
69个球囊扩张式血管内支架(Palmaz支架)被置入57例患者的65条髂动脉中。支架置入的指征包括完全闭塞(n = 15)、经皮腔内血管成形术(PTA)后再狭窄(n = 13)、夹层(n = 4)、术后狭窄(n = 3)或其他情况(n = 30)。支架置入后,收缩压峰值梯度从43.9降至2.9,平均压力梯度降至1.9 mmHg。这显著低于传统PTA(残余收缩压峰值梯度:5.8)。7.7%的所有干预措施出现了并发症。78.4%的患者在支架置入后无限制性跛行。47周后的血管造影对照显示平均内膜增生0.4 mm,未导致明显再狭窄。16个月后的累积通畅率为96%。髂动脉支架成为PTA有效的且在某些情况下不可或缺的辅助手段。
