We have been investigating the safety and efficacy of multiple and different stent types placed in the unfavorable situation of a very long dissection (> 20 mm) after coronary angioplasty. We report our preliminary experience in 20 patients who were treated by the following combinations: Palmaz-Schatz and Micro stent (14 patients). Wallstent and Micro stent (4 patients); Wiktor and Micro stent (1 patient); and Palmaz-Schatz, Micro and Wallstent (1 patient). Normal distal flow was restored in all except one (no reflow phenomenon) patient and complete covering of the dissection was obtained in all but two patients. Event-free survival at 30 days was 90% (18 of 20 patients). During follow-up (mean period: 8 +/- 3 months), two patients died. Of the 18 other patients, 16 remained asymptomatic and free of complications. Symptomatic restenosis was treated by standard angioplasty in the two remaining patients. In conclusion, placement of different stent types seems a feasible, safe, and efficient treatment for very long dissections caused by standard angioplasty.
我们一直在研究在冠状动脉血管成形术后非常长的夹层（>20毫米）这种不利情况下植入多种不同类型支架的安全性和有效性。我们报告了20例患者的初步经验，这些患者接受了以下组合治疗：Palmaz-Schatz支架和Micro支架（14例患者）；Wallstent支架和Micro支架（4例患者）；Wiktor支架和Micro支架（1例患者）；以及Palmaz-Schatz支架、Micro支架和Wallstent支架（1例患者）。除1例（无复流现象）患者外，所有患者均恢复了正常的远端血流，除2例患者外，所有患者的夹层均得到完全覆盖。30天时无事件生存率为90%（20例患者中的18例）。在随访期间（平均时间：8±3个月），2例患者死亡。在其他18例患者中，16例仍无症状且无并发症。其余2例患者的症状性再狭窄通过标准血管成形术进行治疗。总之，对于标准血管成形术引起的非常长的夹层，植入不同类型的支架似乎是一种可行、安全且有效的治疗方法。
