目的探讨长期血透合并心衰患者在心衰纠正前后其血管蒂宽度(VPW)的改变及其临床意义。方法随机选取25例尿毒症并心衰血透患者,加强超滤、纠正心衰治疗4周,测量其 4周前后VPW,心脏横径(TD),干体重、对比其他胸片征象。结果心衰纠正前VPW、TD、干体重分别为(7．14±0．52)cm、(16．05±1．63)cm、(57．60±9．23)kg,心衰纠正后VPW、TD、干体重分别为5． 84±0．30 cm、14．10±1．12 cm、52．80±7．31 kg,三组心衰纠正前后差异比较均有统计学意义(P<0． 05)。结论 VPW作为一种简单、易测的影像学参数,在指导对血透病人容量负荷的判断,干体重的调整方面,有较为重要的临床意义。
Objective To investigate the changes of vascular width (VPW) in patients with chronic hemodialysis and heart failure before and after the correction of heart failure and its clinical significance. Methods Twenty - five uremic patients with heart failure and hemodialysis were enrolled in this study. Ultrafiltration was performed to correct heart failure for 4 weeks. VPW, TD, and body weight were measured before and after 4 weeks. The signs of other chest radiographs were compared. Results Before correction of heart failure VPW, TD and dry weight were (7.14 ± 0.52) cm, (16.05 ± 1.63) cm and (57.60 ± 9.23) kg, respectively. After correction of heart failure VPW, TD, dry weight were 5. 84 ± 0.30 cm, 14.10 ± 1.12 cm and 52.80 ± 7.31 kg, respectively. There was significant difference between the three groups before and after the correction of heart failure (P <0.05). Conclusion As a simple and easy-to-measure imaging parameter, VPW has more important clinical significance in judging the capacity load of hemodialysis patients and adjusting the dry weight.
