International Circulation: One serious complication of transradial coronary intervention is radial artery occlusion， so it is important to adequately assess the circulation issues in the hand before the procedure. My question is whether the Allen test is enough to assess， especially for diabetic patients. 《国际循环》：经桡动脉介入治疗的一个严重并发症是桡动脉闭塞，为此应在术前充分评估手部的血运情况。我的问题是单纯进行Allen试验进行评估是否已经足够，尤其对糖尿病的患者。
