Primary and assisted patency at 6 months. [] in 1991.The CB (Boston Scientific, Natick, initially distributed by InterVentional Therapeutics) was approved as a treatment modality for coronary "high-pressure, balloon-resistant lesions" including de novo lesions and in-stent restenosis (ISR) [] in 1995.Originally developed for the coronary field, where many . . The primary indications are. A cutting balloon is an angioplasty device invented by Barath et al. The Barath cutting balloon 1 was designed specifically to address the problems of barotrauma-related complications of POBA. There are several limitations to be mentioned in our study. Stenoses < 20 mm. The device is a non-compliant balloon which when expanded has three or four longitudinally mounted microtomes on the external surface. FIGURE 13-10 Magnified image of an inflated cutting balloon showing the exposed atherotomes fixed to the long axis of the . SPECIFIC AIMS. They should be . The Cutting Balloon is a unique angioplasty device used in percutaneous coronary interventions. Angiograms will then be performed before and after intervention. The feasibility and safety of the cutting balloon in bifurcation lesions has been reported in several observational registries (54, 55, 56, 57, 58). The cutting balloon (CB) 1 is a special balloon catheter with three or four atherotomes (microsurgical blades) bonded longitudinally to its surface, suitable for creating discrete longitudinal incisions in the atherosclerotic target coronary segment during balloon inflation. Request PDF | Indications for Cutting Balloon Angioplasty: An Israeli Single Center Experience. Patients with signs of AV access failure who are found to have significant stenosis (more than 50%) at the venous end of the anastomosis will then be randomized to either high pressure balloon (Conquest) or to a cutting balloon (Boston scientific Balloon). Cutting balloon angioplasty was used if high-pressure balloon angioplasty failed to efface the lesions. Bifurcation stenoses, origin of the side branch. The advantage of the Cutting Balloon is its ability to reduce vessel stretch and vessel injury by scoring the vessel longitudinally rather than causing an uncontrolled disruption of the atherosclerotic pl . Use of the Cutting Balloon Device is contraindicated in situations where the Cutting Balloon Device would be passed through the struts of a previously placed stent as the deflated Cutting Balloon Device could become entangled in the stent. 994-1000. The manufacturer's and generally accepted clinical indications and contraindications for use of rotational atherectomy are shown in Table 13-5. The Cutting Balloon has been used most often in focal fibrocalcific or "nondilatable" lesions (although it has a relatively low 1. Designed for multiple Indications The Peripheral Cutting Balloon device is designed for multiple indications: . The Peripheral Cutting Balloon Device is not for use in the coronary arteries or carotid arteries. Data will be collected . The cutting balloon may have an extended indication. The Peripheral Cutting Balloon Device is not for use in the coronary arteries or carotid arteries. A number of evolving clinical indications for cutting balloon angioplasty (CBA) have been described in the clinical literature, including angioplasty-resistant stenoses, in-stent restenosis, ostial lesions and small vessel disease. 2. Stenoses in smaller vessels (< 3.0 mm) Ostial stenoses. It has a special balloon tip with small blades, that are activated when the balloon is inflated. The procedure is not suitable for 10 ATM expands your treatment options. Other devices like cutting and scoring balloons cause small incisions in the plaque leading to more expansion of lesions and eliminates dissection which are uncontrolled [25]. Study endpoints will be: Primary Endpoint. There have been some reports of the efficacy of these balloons compared to conventional balloons. With the cutting balloon, the increase in the vessel lumen diameter is obtained in a more controlled fashion and with a lower balloon inflation pressure than conventional percutaneous transluminal coronary angioplasty . This procedure is different from Rotoblation (Percutaneous Transluminal Rotational Atherectomy or PCRA) whereby a diamond tipped device . J Vasc Interv Radiol, 18 (2007), pp. Angioplasty of long venous stenoses in hemodialysis access: at last an indication for cutting balloon? If both techniques failed, the patient was referred for surgical revision. | Background: The Cutting Balloon (CB) is an angioplasty device with side blades bonded to a balloon . Secondly, for better evaluating for safety of cutting balloon, a longer follow-up study should be needed to confirm conclusions. limited indications.7 More recently, larger-diameter bal-loons have been developed for PAD; however, they are only available in relatively short lengths (10-20 mm) due to the stiffness of the device. Direct stenting and conventional BA in bifurcation lesions may cause plaque shifting. The cutting balloon has been demonstrated to minimize plaque shifting . used in percutaneous coronary interventions. Operator experience will dictate comfort levels with these parameters. Pretreatment using a sequential cutting balloon inflation in bifurcation lesions before stent deployment in the main vessel, followed by final kissing balloon inflation in both vessels, is . The cutting balloon (CB) was first designed and reported by Barath et al. Peripheral Cutting Balloon Microsurgical Dilatation Device Rated Burst Pressure: *Please contact your local Boston Scientific representative for product availability in your respective country. The proposed study will investigate the efficacy of the peripheral cutting balloon (PBC) compared to the high pressure balloon in dilating venous stenosis in hemodialysis fistulas. Secondary Endpoints: Procedure effectiveness/residual stenosis There is extensive data for cutting balloons available from clinical studies. In-stent restenoses, preferably focal. However, there have been no reports exploring which balloon is most effective among these three types of balloons. Use of the Cutting Balloon Device is contraindicated in situations where the Cutting Balloon Device would be passed through the struts of a previously placed stent as the deflated Cutting Balloon Device could become entangled in the stent. Cutting Balloon Indications and Contraindications. There are significant potential complications relating to the use of a cutting balloon within a stent, and those previously described during treatment of ISR include microblade fracture and subsequent coronary mural hematoma , stent strut avulsion during ballooning , and balloon entrapment inside a stent after inflation with subsequent stent . Cutting balloons (CBs) and other scoring balloons are known to be useful for plaque modification in heavily calcified lesions. Firstly, this represented a single center study and the number of patients was relatively small. As with many interventional devices there are relative indications and .
