We report on treatment of a patient in whom failure to deploy the distal portion of a Palmaz-Schatz stent occurred but was not recognized. After an unstable course, the patient underwent repeat coronary angiography, at which time the stent was rewired and redilated. Full deployment of the stent with restoration of TIMI grade 3 flow was achieved. The putative cause of the problem, incomplete deployment of the stent because of inadvertent advancement of the stent delivery sheath, should be avoided, and needs to be recognized if it occurs. Crossing and redilating the stent is possible, although technically difficult.
我们报告了一例患者的治疗情况，该患者在植入Palmaz-Schatz支架时远端部分未能展开，但当时未被识别。在经历不稳定病程后，患者接受了再次冠状动脉造影，此时对支架重新进行了导丝通过并再次扩张。支架得以完全展开，恢复了TIMI 3级血流。问题的推测原因是由于支架输送鞘意外推进导致支架未完全展开，应避免这种情况发生，若发生则需要识别出来。虽然技术上有难度，但穿过并再次扩张支架是可行的。
