Deep intubation of coronary guides may improve the backup support required to deliver interventional materials through 6 French catheters. Eighteen patients (17 male, 1 female) with 20 lesions were selected for transradial angioplasty and stenting using the Cordis Long Brite Tip¨ guide. Patients with an evolving acute myocardial infarction and those with an abnormal Allen test were excluded. All patients were pretreated with aspirin, ticlopidine, and heparin. The mean age was 55 (range 34Ð81). The target vessel was the right coronary in 6 of 20 (30%), the circumflex artery in 6 of 20 (30%), left anterior descending in 4 of 20 (20%), vein grafts in 3 of 20 (15%), and ramus intermedius in one case (5%). Seventeen lesions were treated with stents, and 3 with PTCA alone. Three lesions received 2 stents. Procedural success (less than 20% residual stenosis) was obtained in 19/20 cases. No dissections were seen as a result of deep intubation. Dampening of pressure and ischemia occurred in only 2 patients. Deep intubation with this guide may be safely used to obtain support when performing 6 French angioplasty and stenting using the transradial approach.
冠状动脉导管的深插入术可能会改善通过6F导管输送介入材料所需的备用支持。选择18例患者（17例男性，1例女性），共20处病变，采用Cordis Long Brite Tip™导管行经桡动脉血管成形术和支架置入术。排除急性心肌梗死进展期患者和Allen试验异常患者。所有患者均接受阿司匹林、噻氯匹定和肝素预处理。平均年龄为55岁（范围34 - 81岁）。20处病变中，右冠状动脉6处（30%），回旋支6处（30%），左前降支4处（20%），静脉桥桥支3处（15%），中间支1处（5%）。17处病变行支架治疗，3处仅行PTCA。3处病变置入2枚支架。20例中有19例手术成功（残余狭窄小于20%）。深插入术未导致夹层形成。仅2例患者出现压力衰减和缺血。使用该导管进行深插入术在经桡动脉途径行6F血管成形术和支架置入术时可安全用于获得支持。
