To evaluate predictors of restenosis at margins of Palmaz-Schatz stents, intravascular ultrasound studies were performed after intervention and at follow-up (5.4 months) in 161 stented lesions. Of 301 stent margins, 77 (26%) were restenotic at follow-up (>50% late lumen loss). Intimal hyperplasia was greater for restenotic than for nonrestenotic stents margins. The dominant periprocedural predictor of stent margin restenosis was the plaque burden of the continuous reference segment.
为评估帕尔马兹-沙茨支架边缘再狭窄的预测因素，对161处置入支架病变在干预后及随访（5.4个月）时进行了血管内超声研究。在301个支架边缘中，77个（26%）在随访时出现再狭窄（晚期管腔丢失>50%）。再狭窄支架边缘的内膜增生比无再狭窄的支架边缘更严重。支架边缘再狭窄的主要围手术期预测因素是连续参考节段的斑块负荷。
