The use of smaller sized catheters for coronary angiography (CA) is increasing, but little is known about the safety of CA with 6F catheters. The authors reviewed all cases of CA in which 6F and 8F catheters were used in adult patients between 1988 and June, 1990. There were 597 patients in the 6F group and 2,409 patients in the 8F group. Cases of CA with 6F catheters were more likely to be elective (95% vs 87%), to have no coronary disease (35% vs 24%), and to be performed by nonfirst-year fellows (70% vs 54%) when compared with CA with 8F catheters. There were 5 cases of coronary artery dissection. The incidence of dissections was significantly higher (p = .007) in the 6F group (0.67%) than in the 8F group (0.04%). The incidence of dissections was highest for first-year fellows using 6F catheters (1.7%), which was significantly higher (p = .008) than for first-year fellows using 8F catheters. The incidence of major vascular complications tended to be lower (p = .068) in the 6F group (0.17%) than in the 8F group (0.95%). In summary, CA with 6F catheters is associated with an increased risk of coronary artery dissection, particularly with less experienced operators, but tends to be associated with a lower risk of major vascular complications.
用于冠状动脉造影（CA）的较小尺寸导管的使用正在增加，但对于使用6F导管进行CA的安全性知之甚少。作者回顾了1988年至1990年6月期间成年患者中使用6F和8F导管进行CA的所有病例。6F组有597例患者，8F组有2409例患者。与使用8F导管进行CA相比，使用6F导管进行CA的病例更有可能是选择性的（95%对87%），没有冠心病（35%对24%），并且由非第一年的研究员进行操作（70%对54%）。有5例冠状动脉夹层。6F组夹层的发生率（0.67%）显著高于8F组（0.04%）（p = 0.007）。使用6F导管的第一年研究员夹层发生率最高（1.7%），显著高于使用8F导管的第一年研究员（p = 0.008）。6F组主要血管并发症的发生率（0.17%）往往低于8F组（0.95%）（p = 0.068）。总之，使用6F导管进行CA与冠状动脉夹层风险增加相关，特别是对于经验较少的操作者，但往往与较低的主要血管并发症风险相关。
