PURPOSE
To compare the incidence of distal emboli occurring during percutaneous transluminal angioplasty (PTA) and primary stent on the superficial femoral artery (SFA) METHODS: A total of 50 consecutive patients were entered in a prospective, randomized trial. Inclusion criteria were the presence of symptomatic limb ischemia due to stenosis or occlusion of the SFA. An embolic protection device was placed in the popliteal artery. The patients were then randomly assigned to undergo primary stent implantation or PTA. The filters were retrieved and sent for histologic examination.
RESULTS
Stenting in the SFA produced more emboli (1.44 mm(3)) than PTA (0.772 mm(3)), P = .031. Reanalyzing the patients according to actual treatment performed, volume of debris in the stent group was 1.271 mm(3) and in the PTA group was 0.191 mm(3), P = .00087.
CONCLUSION
Volume of embolized material during endovascular interventions in the SFA-above-knee popliteal artery is higher when a stent is used.
目的
比较经皮腔内血管成形术（PTA）和股浅动脉（SFA）初次支架置入过程中远端栓子的发生率。
方法
共有50例连续患者进入一项前瞻性随机试验。纳入标准为因SFA狭窄或闭塞导致的有症状肢体缺血。在腘动脉放置一个栓子保护装置。然后将患者随机分配接受初次支架置入或PTA。取出过滤器并送去进行组织学检查。
结果
SFA支架置入产生的栓子（1.44立方毫米）比PTA（0.772立方毫米）多，P = 0.031。根据实际进行的治疗重新分析患者，支架组的碎片体积为1.271立方毫米，PTA组为0.191立方毫米，P = 0.00087。
结论
在SFA - 膝上腘动脉进行血管内介入治疗时，使用支架时栓塞物质的体积更高。
