在血管造影操作中,为了使操作时间缩短,成功率高、并发症少,术者必须对导管与导丝有充分了解,使各种器械发挥其应有的作用并得以正确使用。一、J型导丝的应用当血管穿刺成功后,术者应插入J型导丝,而不是直型导丝。尤其是用经典Seldin-ger法穿刺时,穿刺针已损伤了血管的后壁,穿刺针退回血管腔时,针头可能仍对准后壁伤孔,甚至距离很近。当 In angiography, in order to shorten the operation time, high success rate, fewer complications, the surgeon must have adequate understanding of the catheter and guide wire, so that a variety of devices to play their due role and be used correctly. First, the application of J-type guide wire When the successful puncture, the surgeon should be inserted J-type guide wire, rather than straight guide wire. Especially when puncturing with the classic Seldin-ger method, the puncture needle has damaged the posterior wall of the blood vessel, and when the puncture needle is retracted into the blood vessel lumen, the needle may still be aligned with the posterior wall puncture and even close. when
