The guiding catheter lock technique is a therapeutic technique to increase backup force of the guiding catheter in coronary artery interventions.
A 71 year old man presented with rapidly declining kidney function resulting from bilateral renal artery stenosis. During the renal artery stenting procedure, the 0.014" guidewire became trapped at the stent's distal edge. Although attempts were made to advance a microcatheter and balloon catheter over the trapped guidewire, these failed because of insufficient pushability of the guiding catheter. Therefore, the guiding catheter lock technique was used with a second guiding catheter, and the guidewire was successfully retrieved.
The guiding catheter lock technique facilitated strong pushability to allow for successful retrieval of a stuck guidewire during renal artery stenting.
引导导管锁定技术是一种在冠状动脉介入治疗中增加引导导管支撑力的治疗技术。
一名71岁男性因双侧肾动脉狭窄导致肾功能迅速下降。在肾动脉支架置入过程中，0.014英寸的导丝被困在支架远端边缘。尽管尝试在被困导丝上推进微导管和球囊导管，但由于引导导管的推送能力不足而失败。因此，使用第二根引导导管采用引导导管锁定技术，成功取出了导丝。
引导导管锁定技术提供了强大的推送能力，从而在肾动脉支架置入过程中成功取出了卡住的导丝。
