目的：为了评估在经皮冠状动脉介入治疗（PCI）过程中是否可以估计患者皮肤的最大辐射剂量（MSD），我们研究了MSD与透视时间、剂量面积乘积（DAP）和体重之间的关系，并分别分析了不同靶血管的关系。背景：已有多起心脏介入手术期间因过度辐射暴露导致皮肤损伤的病例报道。然而，许多心脏介入手术无法实时监测皮肤最大剂量。方法：我们研究并实施了涉及单个目标血管的 197 例连续 PCI 手术。测量DAP，并通过皮肤剂量绘图软件程序(Caregraph)计算MSD。根据AHA分类系统将PCI手术的靶血管分为四组：AHA 5-10，左前降支动脉域（LAD），AHA 11-15，左旋支动脉域（LCx），AHA 1-3 = R 1-3，AHA 4 = R 4。 结果：右冠状动脉的MSD与透视时间之间的相关系数（r）较高 (RCA) 血管 (R 1-3, 0.852; R 4, 0.715) 高于左冠状动脉 (LCA) 血管 (LAD, 0.527; LCx, 0.646)，并且 RCA 血管的 MSD 和 DAP 之间的 r 值 (R 1-3, 0.871; R 4, 0.898) 高于 LCA 血管 (LAD, 0.527; LCx, 0.646)。 0.628; 0.694）。同样，RCA 血管的 MSD 和重量 x 透视时间 (WFP) 之间的相关系数 (R 1-3, 0.874; R 4, 0.807) 高于 LCA 血管 (LAD, 0.551; LCx, 0.735)。结论：DAP 和 WFP 可用于估计 RCA 中 PCI 期间的 MSD，但不能用于 LCA，尤其是 LAD。 (C) 2006 Wiley-Liss, Inc.
Objectives: To evaluate whether the maximum radiation dose to the patient's skin (MSD) can be estimated during percutaneous coronary intervention (PCI) procedures, we investigated the relationship between the MSD and fluoroscopic time, dose-area product (DAP), and body weight, separately analyzing the relationships for different target vessels. Background: Many cases of skin injury caused by excessive radiation exposure during cardiac intervention procedures have been reported. However, real-time maximum-dose monitoring of the skin is unavailable for many cardiac intervention procedures. Methods: We studied 197 consecutive PCI procedures that involved a single target vessel and were conducted. The DAP was measured, and the MSD was calculated by a skin-dose mapping software program (Caregraph). The target vessels of the PCI procedures were divided into four groups based on the AHA classification system: AHA 5-10, left anterior descending artery domain (LAD), AHA 11-15, left circumflex artery domain (LCx), AHA 1-3 = R 1-3, and AHA 4 = R 4. Results: The correlation coefficient (r) between the MSD and fluoroscopic time was higher for the right coronary artery (RCA) vessels (R 1-3, 0.852; R 4, 0.715) than for the left coronary artery (LCA) vessels (LAD, 0.527; LCx, 0.646), and the r value between the MSD and DAP was higher for the RCA vessels (R 1-3, 0.871; R 4, 0.898) than for the LCA vessels (LAD, 0.628; LCx, 0.694). Similarly, the correlation coefficient between the MSD and weight x fluoroscopic time (WFP) was higher for the RCA vessels (R 1-3, 0.874; R 4, 0.807) than for the LCA vessels (LAD, 0.551; LCx, 0.735). Conclusions: The DAP and WFP can be used to estimate the MSD during PCI in the RCA but not in the LCA, especially the LAD. (C) 2006 Wiley-Liss, Inc.
