The data on 36 patients who had undergone coronary angiography (CAG) and/or transluminal balloon angioplasty (TBAP) again after successful TBAP were analyzed. Twenty four patients were found to develop restenosis (n = 26), 80 and 92% of patients having them within the first 6 and 12 months after successful TBAP, respectively. Restenosis were demonstrated to be of almost the same degree and extent as the baseline stenoses; however, after repeated TBAP there was a slight reduction in the extent of residual stenosis as compared with the first TBAP (15.9 +/- 16.1% and 30.8 +/- 16.6%, respectively), though this difference was insignificant. At baseline, 42% of dilated stenoses were complicated and/or eccentric, while restenosis were eccentric in 16% of cases (p < 0.05) and complicated in 21% (p < 0.05). Thus, restenoses are X-ray morphologically more favourable for TBAP.
对36例在经皮腔内球囊血管成形术（TBAP）成功后再次接受冠状动脉造影（CAG）和/或经皮腔内球囊血管成形术（TBAP）的患者的数据进行了分析。发现24例患者发生再狭窄（n = 26），分别有80%和92%的患者在成功实施TBAP后的前6个月和12个月内出现再狭窄。结果表明，再狭窄的程度和范围与基线狭窄几乎相同；然而，与首次TBAP相比，重复实施TBAP后残余狭窄程度略有降低（分别为15.9 +/- 16.1%和30.8 +/- 16.6%），尽管这种差异不显著。基线时，42%的扩张狭窄为复杂型和/或偏心型，而再狭窄病例中16%为偏心型（p < 0.05），21%为复杂型（p < 0.05）。因此，从X线形态学角度来看，再狭窄对TBAP更为有利。
