Coronary angioplasty using an over-the-wire balloon catheter through a new 6 french guiding catheter

摘要: A new 6 French (F) guiding catheter with a large, teflon-coated internal lumen (4.2F) was developed, permitting use of the standard ultralow profile (less than 3F) over-the-wire system. This small coronary angioplasty system (6F-PTCA) evaluated in 48 lesions 45 137 patients (33%) who underwent between September 1990 and January 1991. The mean age 64 years (range 49 to 82); 37 (82%) were male. procedure via brachial artery 28 (62%). overall primary success rate 96%. It 100% 90% femoral artery. There no major complications. puncture compression time 6F-PTCA 8F-PTCA 3.8, 9.6, 16.9 hr, respectively (P less 0.001), although not significantly different. hospital stay 3.1, 4.5, 5.5 days, 0.01). hematoma occurred 2 (4.4%) after 3 (3.3%) 8F-PTCA, large (greater 5 cm) noted 7 (7.6%) 8F-PTCA. These results indicate that using through 6F is technically feasible. Moreover, this approach, especially when advanced artery, could shorten hemostasis facilitate early ambulation.
