西班牙学者Sanmartin等发现,经桡动脉途径介入治疗术后,常规压迫止血往往完全阻断了桡动脉血流,并且这种血流中断与术后桡动脉闭塞存在着密切的关系。作者选择275例行桡动脉途径介入治疗的患者进行前瞻性序贯研究,术中采用自动定量血管照影术估算桡动脉直径,术后即拔出动脉套管,敷料常规压迫止血2h,随访7d。分别于加压绷带包扎即刻,2h后(撤绷带前), The Spanish scholar Sanmartin et al found that routine interventional hemostasis often completely blocked radial artery blood flow after interventional treatment of the radial artery. This interruption of blood flow is closely related to postoperative radial artery occlusion. The authors selected 275 patients undergoing radial artery interventional treatment in patients with prospective sequential study, the use of automatic quantitative angiography radial artery diameter estimation, removal of arterial cannula postoperatively, dressing conventional compression hemostasis 2h, follow-up 7d . Respectively in the bandage bandage immediately, 2h (withdrawal bandage before),
