Objectives : We evaluated a sheathless transradial technique for interventions using standard five and six French nonhydrophilic guiding catheters. Background : Miniaturization of transradial interventions may serve to improve patient comfort and reduce the risk of access‐site complications. Guiding catheters carry an outer diameter approximately 2 Fr sizes smaller than their corresponding introducer sheaths. Methods : We identified consecutive patients who underwent transradial intervention between August 2010 and December 2010 using 5 or 6 Fr guides with a sheathless technique. Results : A total of 11 patients were identified (mean age 70.7 ± 10.9 years; 73% male). Single coronary intervention was performed in 10 patients and renal artery intervention in one. Right radial access and 6 Fr guide catheters were used in the majority (each 73%). Five techniques were used to create an inner dilator as the taper. Four of these inner tapers (standard diagnostic catheters, hydrophilic diagnostic catheters, long sheath dilators and guide extensions) enabled successful sheathless guide insertion in all 10 patients attempted. One technique (a partially inflated angioplasty balloon protruding from the guide) attempted in one patient was unsuccessful. All interventional procedures were successful, there were no radial artery access‐site complications and in no case was cross‐over to femoral artery access‐site required. Conclusion : Sheathless transradial intervention using standard 5 and 6 Fr guiding catheters is a safe and effective method for treatment of coronary and peripheral vascular lesions. © 2011 Wiley Periodicals, Inc. 相似文献

OBJECTIVE:
To investigate the feasibility and safety of using sheathless standard guiding catheters for transradial percutaneous coronary intervention (PCI) to treat bifurcation lesions.METHODS:
Coronary bifurcation lesions were identified using angiography in 43 patients with coronary artery disease. These patients underwent transradial PCI using sheathless standard guiding catheters, and the procedural success and complication rates were recorded.RESULTS:
All 43 patients underwent successful PCI. The Culotte stenting technique was used in 22 (51.2%) subjects, the Crush stenting technique was used in eight (18.8%) subjects and the crossover stenting implantation technique was used in 13 (30.0%) subjects. Of the 43 coronary artery bifurcation lesions, the final kissing balloon technique was performed in 39 (90.1%) lesions. Adjunctive devices used in the cohort included intravascular ultrasound for 32 (74.4%) patients, thrombus aspiration catheters for two patients and cutting balloon for five patients. During the perioperative period, no major complications associated with vessel puncture or adverse cardiac or cerebrovascular events occurred in any of the 43 patients enrolled in the present study. At day 30, radial artery occlusion was detected in only three (2.5%) patients and radial artery stenosis in four (9.3%) patients. At six-month follow-up, 24 (55.8%) patients exhibited coronary artery patency with no significant intimal hyperplasia.CONCLUSIONS:
Transradial PCI using the sheathless technique may be a feasible and safe technique to treat coronary bifurcation lesions. 相似文献13.

Background: Transradial approach (TRA) for percutaneous coronary interventions (PCIs) is a common alternative to transfemoral approach associated with lower complications. However, a limitation of TRA is the use of large caliber guiding catheters due to the small size of the radial artery. The sheathless guiding catheter system that is in diameter 1–2 French (Fr) smaller than the corresponding introducer sheath may overcome these difficulties. Methods: From January 2010 through December 2010 in 5 Italian high‐volume hospitals, 213 consecutive patients who underwent TRA‐PCIs using the sheathless Eaucath guiding catheter system because of small radial artery caliber (Group 1) or undergoing bifurcation PCIs (Group 2) were enrolled in this registry. In patients of Group 1 (n = 79), a 6.5‐Fr sheathless guiding catheter was employed, whereas in patients of Group 2 (n = 134) a 7.5 Fr was used. Results: Among the 213 patients enrolled, 270 vessels were treated for 316 lesions. No procedures required conversion to a conventional guiding catheter system. There were significantly more female patients in Group 1, and they were, older, shorter, and thinner than patients in Group 2. No cases of major vascular complications were observed in either groups. During procedures, adjunctive devices employed included intravascular ultrasound, thrombectomy catheters, and distal protection systems. Conclusions: The use of the sheathless guiding catheter system is feasible for TRA‐PCIs in case of small radial artery caliber or intended coronary bifurcation intervention.

A 6.5‐Fr guiding catheter (Parent Plus 45, Medikit, Tokyo, Japan), composed of a hydrophilic sheathless guiding catheter and a dilator, has recently been developed for the treatment of renal artery stenosis. Because of its unique sheathless configuration, its outer diameter is comparable to that of a conventional 4.5‐Fr introducer sheath, with the inner diameter being close in size to a 6.5‐Fr guiding catheter. These features allow this sheathless system to be used as the sole guiding catheter while the arterial damage at the puncture site remains equivalent to that of a 4.5‐Fr introducer sheath. We thus call this novel sheathless guiding catheter a virtual 4.5‐Fr system. To demonstrate the potential of this virtual 4.5‐Fr system, we report a case of renal artery stenosis successfully treated via the transradial route. This virtual 4.5‐Fr system may become a viable alternative to conventional guiding catheters, and provide a favorable impact upon vascular access complications and patient morbidity. © 2012 Wiley Periodicals, Inc. 相似文献

Distal transradial access (dTRA) is a novel alternative to conventional radial artery access for coronary catheterization. However, the feasibility and safety of repeated use of dTRA have not been fully elucidated. This study aimed to evaluate the feasibility and safety of the repeated use of dTRA for coronary angiography and intervention in the same arm. A total of 1717 patients underwent angiography or angioplasty via dTRA. We retrospectively analyzed the catheterization records of patients who underwent repeated puncture of the distal radial artery in the same arm. The incidence of successive applications of dTRA and the reasons for dropout were retrospectively investigated. A total of 416 patients, including three who underwent coronary catheterization with the bilateral dTRA in the initial attempt were analyzed. A 3-, 4-, 5-, or 6-French sheath or sheathless guide catheter was used in the initial procedure. A maximum of four successive coronary catheterization procedures were performed. The second procedure with dTRA on the same arm was successfully performed in 395 cases (94.3%), with a successive rate of 89.6% for both the third and fourth dTRA procedures. Conversion to another approach site (n = 30) was attributed to radial artery occlusion (n = 9), narrowing of the distal radial artery (n = 19), and puncture failure (n = 2). The current data indicate that the repeated use of dTRA is safe and feasible, and this approach may become a standard approach site in the future. 相似文献

Background : We have recently reported a novel percutaneous coronary intervention (PCI) system using a hydrophilic‐coated sheathless guiding catheter (Virtual 3‐Fr, Medikit, Tokyo, Japan), which provides us with less invasive angioplasty and a puncture site injury equivalent to a conventional 3‐Fr introducer sheath. Here, we report the initial results of PCI using this novel system. Methods : A total of 36 coronary artery lesions of 27 patients were treated by using a virtual 3‐Fr PCI system. Procedural outcomes of virtual 3‐Fr PCI were retrospectively evaluated. Results : The mean age was 73.0 ± 8.7 years (range, 46–84 years), and 15 were men (56%). Access sites included the radial artery in 18 patients (67%), the brachial artery in eight patients (30%), and the femoral artery in 1 patients (4%). Among 36 lesions, seven were chronic total occlusions, and a virtual 3‐Fr PCI was successful in 33 lesions (92%). Among the successfully treated 33 lesions, coronary stents were deployed in 32 (97%), and intravascular ultrasound examination was performed in 19 (58%). Hemostasis was achieved immediately after PCIs in all cases. No access‐site related complications including radial artery occlusion were observed. Conclusions : The performance of a virtual 3‐Fr PCI system appears to be comparable to one using a regular 5‐Fr guiding catheter while the puncture‐site damage remains equivalent to that of a 3‐Fr introducer sheath. Virtual 3‐Fr PCI may have a potential to serve as a minimally invasive strategy for the treatment of coronary artery diseases. © 2010 Wiley‐Liss, Inc. 相似文献

We have recently developed a 5‐Fr sheathless guiding catheter system (Virtual 3‐Fr, Medikit, Japan), composed of a hydrophilic catheter and a central dilator. This combination of catheter and dilator enables us to introduce the catheter into the artery without the need of an introducer sheath. Because the outer diameter of this 5‐Fr sheathless guiding catheter system is approximately 2‐Fr sizes smaller than a conventional guiding catheter system, this system provides us with less invasive angioplasty and a puncture site injury equivalent to a conventional 3‐Fr introducer sheath. To demonstrate the potential of this 5‐Fr sheathless guiding system, we report two cases of chronic total occlusion successfully treated by the transradial approach. This novel 5‐Fr sheathless system may become a viable alternative to conventional guiding catheters, and provide a favorable impact upon vascular access complications and patient morbidity. © 2009 Wiley‐Liss, Inc. 相似文献
