Abstract
BACKGROUND Endovascular interventions in infrapopliteal occlusive artery disease are becoming more complex, and this frequently tests the standard method of treatment, plain old balloon angioplasty (POBA). The potential that serration angioplasty could produce a more acceptable tibial artery lumen was assessed in this study. AIM The aim of this single-center subgroup analysis was to compare acute angiographic results after endovascular treatment using the Serranator serration balloon catheter in patients participating in the PRELUDE-BTK trial with POBA of the infrapopliteal arteries. A secondary objective was to assess post-treatment hemodynamic improvements. METHODS Our center enrolled 15 subjects and treated 17 lesions within the multicenter prospective core laboratory-adjudicated PRELUDE-BTK study. A 25 lesions analyzed separately were treated with POBA and then compared with the Serranator subset. In both cohorts, lesions were treated with either plain angioplasty or Serranator as a stand-alone therapy; subsequent methods, such as drug elution technologies, were not used. Acute angiographic results were analyzed by the SynvaCor angiographic core laboratory. To assess volumetric flow rates, data were analyzed with a fluid flow simulation software and compared against Poiseuille's Law. RESULTS Final residual stenosis was 17.2%±8.2% in the Serranator group versus 33.7%±15.7% in the POBA group. The mean lumen diameter (MLD) gain for the Serranator group and the POBA group was 1.64±0.41 mm and 1.33±0.63 mm, respectively. The average atmospheric balloon inflation pressure was 5 ATM in the Serranator group versus 9 ATM in the POBA group. Neither group required a bailout stent; however, it was notable that there were significantly more chronic total occlusions (CTOs) treated in the Serranator group at 41.2% versus 12% in the POBA group. Regarding the effectiveness in improving hemodynamic blood flow for non-CTO lesions, the calculated average ratio of post-treatment to pre-treatment flow rates in the Serranator group was 238% than that for the POBA group. For CTO cases where pre-treatment flow rate was zero, final residual stenosis was used as the parameter for comparison. The Serranator group showed a 62% improvement in final residual stenosis over POBA. CONCLUSION Endovascular treatment of the infrapopliteal arteries by use of the Serranator serration balloon provides a novel and promising method of action compared with standard balloon angioplasty and, thus, may have a leading role in complex below-the-knee arterial lesions. CLINICAL IMPACT The Serranator device might help to adequately address issues with conventional routine techniques for the treatment of complex lesions in infrapopliteal arteries in patients with advanced stages of PAD and critical limb ischemia. Integrating modern technologies such as the Serranator balloon catheter into clinical routine is mandatory in order to gain a more favorable outcome in these severely diseased patients and, particularly, to reduce mortality and morbidity.

Abstract
PURPOSE Infrapopliteal lesions are generally complex to treat due to small vessel diameter, long lesion length, multilevel disease, and severe calcification. Therefore, different vessel preparation devices have been developed to contribute to better peri- and postprocedural outcomes. This systematic review aims to compare different vessel preparation techniques prior to plain old balloon angioplasty (POBA) or drug-coated balloon (DCB) angioplasty with POBA or DCB alone in infrapopliteal arterial disease. METHODS Medline, EMBASE, and Cochrane databases were searched for studies published between 2000 and 2022 assessing the value of adjunctive vessel preparation in infrapopliteal arterial disease. The primary outcomes were 12-month primary patency and limb salvage. RESULTS A total of 1685 patients with 1913 lesions were included in 11 POBA studies. Methodological quality was assessed as poor to moderate in these studies. Only 2 studies with 144 patients assessed vessel preparation in conjunction with DCB angioplasty. These randomized trials were assessed as high quality and found no significant benefit of adjunctive atherectomy to DCB angioplasty. The pooled Kaplan-Meier estimates of 12-month primary patency and limb salvage in the POBA studies were 67.8% and 80.9% for POBA, 62.1% and 86.4% for scoring balloons, 67.9% and 79.6% for mechanical atherectomy (MA), and 79.7% and 82.6% for laser atherectomy, respectively. Within the pooled data only scoring balloons and MA demonstrated significantly improved 12-month limb salvage compared to POBA. CONCLUSIONS Different forms of adjunctive vessel preparation demonstrate similar 12-month outcomes compared to POBA and DCB angioplasty alone in infrapopliteal disease, with the exception of improved 12-month limb salvage in scoring balloons and MA. However, since the included studies were heterogeneous and assessed as poor to moderate methodological quality, selection bias may have played an important role. Main conclusion is that this systematic review found no additional value of standard use of vessel preparation. CLINICAL IMPACT Infrapopliteal arterial disease is associated with chronic limb-threatening ischemia (CLTI) and generally complex to treat due to small vessel diameter, long lesion length, multilevel disease and severe calcification. A wide range of vessel preparation devices have been developed to contribute to improved peri- and postprocedural outcomes in these complex lesions.

Abstract
Since its Food and Drug Administration approval in January 2007, the Angiosculpt scoring balloon catheter has been widely utilized in severely calcified stenotic vascular lesions. We sought to characterize the complication rates, failure modes, and outcomes associated with the Angiosculpt catheter. Using queried events from October 2013 to December 2020 from the Food and Drug Administration Manufacturer and User Facility Device Experience database, we analyzed the Angiosculpt scoring balloon catheter complication rates and mode of failure. A total of 248 complications were reported. Most reported complications occurred in the superficial femoral artery (SFA) (19.4%, n = 48), followed by the left anterior descending artery (8.1%, n = 20). Severe vessel calcifications were reported in (26.6%, n = 66) of the complications. Most complications occurred with damage to the device, such as tip break (44.8%, n = 111) and balloon rupture (26.6%, n = 66). Some complications were due to difficulties in the withdrawal of the catheter (23.8%, n = 59). Balloon rupture is observed at a significantly higher rate amongst calcified vessels (60.6% vs 14.8%), P = < 0.001, and in cases involving the SFA (39.4% vs 11.3%), P = < 0.001. All-cause complications in calcified vessels are associated with the SFA (39.4% vs 12.5%), P = < 0.001, and left anterior descending artery (16.7% vs 5.1%), P = < 0.001. The Angiosculpt scoring balloon catheter has a relatively low complication rate. Most complications were associated with a device tip break, balloon rupture, and difficulties in withdrawal in severely calcified vessels.

Abstract
The aim of this case series was to document our early experience using combination therapy with UltraScore™ Focused Force percutaneous transluminal angioplasty balloon (BD Interventional, New Jersey, US) and Selution Sustained Limus Release (SLR)™ (M.A. MedAlliance SA, Nyon, Switzerland) sirolimus-coated balloon catheter for anti-restenotic drug elution, in the setting of multifocal high-grade stenosis for chronic limb threatening ischaemia. Our anecdotal experience was that preparing the lesion with scoring balloon and then using sirolimus drug-eluting balloon may have synergistic effect when used in tandem, especially in the setting of calcified arterial lesions, where the scoring wires may achieve deeper clefts within the atheromatous plaque to allow better drug absorption into the arterial wall. We report two cases with high-grade multifocal stenosis affecting the superficial femoral and anterior tibial arteries, respectively. Combination therapy using the scoring balloon to first prepare the lesion followed by sirolimus elution achieved technical and procedural success in both cases and a 100% 30-day primary patency. There were no complications related to flow-limiting dissections, vessel perforation or acute recoil. However, whether this combination therapy leads to better primary vessel patency with longer freedom from target lesion revascularization in the medium term remains to be determined.

Abstract
PURPOSE The purpose was to evaluate the safety and efficacy of the Serranator percutaneous transluminal angioplasty serration balloon catheter in patients with infrapopliteal peripheral artery disease. MATERIALS AND METHODS A prospective, multicenter, single-arm feasibility study in 46 patients with claudication or chronic limb-threatening ischemia, Rutherford Clinical Category (RCC) 3 to 5, that required treatment of the infrapopliteal arteries above the tibiotalar joint. The primary efficacy outcome was device success-successful insertion, balloon inflation and deflation, and removal of the device(s) with a final diameter stenosis of <50%. The primary safety endpoint was a composite of major adverse limb events (MALE) and perioperative death (POD) through 30 day postprocedure. Other outcomes were change in RCC and ankle-brachial index, wound healing, and clinically-driven target lesion revascularization (CD-TLR). A subset of 9 patients were further evaluated by optical coherence tomography (OCT) or intravascular ultrasound (IVUS) for the presence of serrations in treated lesions. Patient follow-up occurred at 30 days and 6 months. RESULTS Forty-six patients received treatment with the Serranator device and 55 lesions were treated. Fifty-three lesions were deemed analyzable by the core lab with data and reported hereafter. Device success was 91.7% and freedom from MALE + POD through 30 days was 95.7%. Pretreatment stenosis of 82% was reduced to 21.8% and only 1 lesion (1.9%) required a bailout stent for a grade D dissection. The average maximum balloon inflation pressure was 6 atmospheres. Serrations were present in all treated lesions (n=10) in 9 patients imaged with OCT/IVUS as reviewed by the core laboratory. The RCC score improved by 1 or more level in 70% of patients at 6 months with 42% having a score of 0. The 6 month freedom from CD-TLR was 97.7%. CONCLUSION Serranator treatment of infrapopliteal lesions showed excellent lumen gain with minimal evidence of arterial injury and low 6 month CD-TLR. Imaging by IVUS and OCT showed serrations without significant dissection, supporting the device's proposed mechanism of action.

Abstract
The below-the-knee arterial tree is the thinnest of all the leg vessels and is an important path for blood flow to the foot. Hence, lesions including stenosis, especially obstruction, may lead to critical limb ischemia which represents the most severe clinical manifestation of peripheral arterial disease. It is characterized by the presence of ischemic rest pain, ischemic lesions, or gangrene attributable to the objectively proven arterial occlusive disease. Typically, the atherosclerotic disease process involving the below-the-knee arterial tree is diffuse in the majority of patients. The cornerstone of therapy is vascular reconstruction and limb salvage. Revascularization should be attempted whenever technically possible, without delay, in patients presenting critical limb ischemia and when the clinical status is not hopelessly non-ambulatory. Therefore, endovascular treatment can become the gold standard for the full range of patients including below-the-knee, limiting the clinical role of the classically trained surgeons.

Abstract
Background: Arteriovenous access failure is most often due to the development of neointimal hyperplastic stenoses. Balloon angioplasty remains standard of care for endovascular treatment of stenoses obstructing blood flow in hemodialysis fistulas and grafts. Scoring balloon technologies have been developed to disrupt the atheromatous plaque and have shown to be safe and effective for treating stenosis in the hemodialysis access circuit. However, improvement in patency has yet to be established. Methods: This prospective, single-arm study included 50 patients with stenosed hemodialysis fistula/grafts treated with the AngioSculpt® scoring balloon (Philips) and followed for 6 months. The primary endpoint was target lesion primary patency at 2 and 6 months defined as freedom from re-intervention. Results: Treatment with the scoring balloon resulted in a reduction in stenosis from 78% ± 13.36% to 7.2% ± 7.57% (mean ± standard deviation). Scoring balloon inflation pressures averaged 11.4 atm; no slippage/dissections occurred. After 2 months, 10% of patients required re-intervention. At 6 months, 19% of patients required re-intervention. The 6-month freedom from re-intervention rate was higher for patients with stenosed fistulas (83.3%) compared to patients with stenosed grafts (71.4%). Six-month patency rates were highest for patients with no or one previous intervention (91.6% and 90.0%, respectively); patients with two to five preceding interventions had a 6-month patency rate of 80%, and those with more than five previous interventions had a 50% 6-month patency rate. Conclusion: Results from this pilot study suggest that the AngioSculpt scoring balloon may be a viable treatment option for stenosed arteriovenous fistula/graft access.

Abstract
Endovascular revascularization has been increasingly utilized to treat patients with chronic limb-threatening ischemia (CLTI), particularly atherosclerotic disease in the infrapopliteal arteries. Lesions of the infrapopliteal arteries are the result of 2 different etiologies: medial calcification and intimal atheromatous plaque. Although several devices are available for endovascular treatment of infrapopliteal lesions, balloon angioplasty still comprises the mainstay of therapy due to a lack of purpose-built devices. The mechanism of balloon angioplasty consists of adventitial stretching, medial necrosis, and dissection or plaque fracture. In many cases, the diffuse nature of infrapopliteal disease and plaque complexity may lead to dissection, recoil, and early restenosis. Optimal balloon angioplasty requires careful attention to assessment of vessel calcification, appropriate vessel sizing, and the use of long balloons with prolonged inflation times, as outlined in a treatment algorithm based on this systematic review. Further development of specific devices for this arterial segment are warranted, including devices for preventing recoil (eg, dedicated atherectomy devices), treating dissections (eg, tacks, stents), and preventing neointimal hyperplasia (eg, novel drug delivery techniques and drug-eluting stents). Further understanding of infrapopliteal disease, along with the development of new technologies, will help optimize the durability of endovascular interventions and ultimately improve the limb-related outcomes of patients with CLTI.

Long-term outcome upon treatment of calcified lesions of the lower limb using scoring angioplasty balloon (AngioSculpt™). Clin Res Cardiol 2020; 109:1177-1185.

Abstract
AIMS In peripheral artery disease (PAD), endovascular treatment success of heavily calcified lesions is often compromised by a number of vascular complications, such as recoils, dissections and need for target vessel re-interventions. The increasing use of scoring balloon techniques has raised the hope for better periprocedural outcomes; however, the knowledge regarding the actual benefits of the scoring balloon technique in comparison to standard therapy is still limited. Thus, the aim of the current study was to determine the safety and effectiveness of scoring balloon angioplasty in a real-life patients' collective with PAD. METHODS AND RESULTS A total of 425 patients with moderate to severely calcified femoropopliteal lesions received interventional treatment between 2011 and 2018 at the single center; 230 received a treatment with a scoring balloon (AngioSculpt™), and 195 received a plain procedure without AngioSculpt™. Key questions of this analysis were: (1) whether AngioSculpt™ can be used as a safe and effective stand-alone treatment in heavily calcified lesions in a 24-month follow-up, as well as (2) whether target lesion preparation with scoring balloon bears additional benefits to standard treatment (PTA ± stent implantation). In terms of freedom from target lesion revascularization there were no significant differences between AngioSculpt™ and standard procedure (82.3% vs. 78.1%, P > 0.05). Vessel preparation with balloon angioplasty had no additional effects on survival and amputation rates in comparison to standard treatment without AngioSculpt™ (P > 0.05). The deployment of a scoring balloon did not reduce the subsequent need for additional stent implantations (32.6%, and 32.3%, P > 0.05). CONCLUSION Lesion preparation with AngioSculpt™ scoring balloon represents a safe and effective tool in the treatment of complex femoropopliteal lesions. In this retrospective analysis, AngioSculpt™ scoring balloon angioplasty did not significantly improve vessel patency- both when used as an adjunctive in preparation for stenting and as stand-alone treatment. A prospective study is needed to further investigate the scoring balloon treatment options.

Abstract
BACKGROUND Highly calcific stenosis located in common femoral artery (CFA) represents a difficult target for endovascular treatment due to the possible need for stent implantation in that area. CASE SUMMARY A 63-year-old man with history of coronary artery disease and previous multiple percutaneous transluminal angioplasties for peripheral artery disease (PAD) was admitted for recent onset left lower limb pain at rest with severe activity restriction (Leriche-Fontaine Class III and Rutherford Class III-IV). The angio-computed tomography scan showed a highly calcific stenosis of left CFA. The patient underwent lithoplasty balloon angioplasty followed by drug-eluting balloon inflation with excellent angiographic result and complete blood flow restoration. No procedural complications occurred. DISCUSSION Highly calcified stenosis in PAD represents a huge challenge for endovascular treatment as not all lower extremity arteries are suitable for stenting because of compressive and torsional forces associated with stent fracture and restenosis. Lithoplasty is a new technology allowing effective blood flow restoration while minimizing vessel injury.

Abstract
INTRODUCTION Percutaneous transluminal angioplasty (PTA) currently remains the endovascular treatment of choice in a large percentage of patients suffering from peripheral artery disease (PAD). However, the mechanism of angioplasty itself can cause some extent of arterial dissection leading to early vessel restenosis/reocclusion. Current endovascular imaging studies have reported a higher rate of arterial dissection than previously reported in literature and advocated the correlation of dissection with poor patency. Thus, there is the need of developing devices to minimize dissection and bailout stenting. AREAS COVERED The present review focuses on newly-developed balloon angioplasty technologies designed to minimize arterial wall distress and consequently the rate of dissections. Available literature regarding three new specialty balloons is being reviewed, highlighting their value and limitations. Authors' future perspective about the benefits of utilizing specialty balloons towards a metal free and dissection free future is also provided. EXPERT OPINION By understanding the mechanism of angioplasty and thus developing devices which cause minimal or no arterial wall distress, the rate of dissections and bailout stenting can be minimized and long-term clinical outcomes of endovascular therapy can be optimized.

Abstract
Purpose: To report outcomes of a multicenter feasibility study using the FLEX Vessel Prep (VP) System, a novel technology that facilitates plaque incision and lumen gain in stenosed or occluded femoropopliteal arteries prior to balloon angioplasty. Materials and Methods: Two hundred fifty-five patients (mean age 71.8±9.1 years) were treated with the FLEX VP System at 38 centers between December 2015 and November 2017. Average lesion length was 133±88 mm. Average baseline stenosis was 92%±11%; 112 (44.3%) of 253 patients presented with a chronic total occlusion. Conventional or drug-coated balloon (DCB) angioplasty was performed in all patients after vessel preparation. Vessel measurements were derived from angiograms acquired at baseline, after FLEX passage, and after subsequent ancillary procedures. Logistic regression analyses were performed to identify baseline or procedure variables that predicted the need for provisional stenting. Results: Average percent reduction in vessel stenosis following treatment with the FLEX VP System was 27%±17%. No flow-limiting dissection, vessel perforation, or embolization was observed; 15 (5.9%) patients had minor (type A or B) dissections. Provisional stenting was performed in 49 (19.2%) patients. Average stenosis following angioplasty ± stenting was 9.1%±7.4%; 9 (3.6%) patients had significant residual stenosis ≥30%. Logistic regression analyses found that patients with dissections, longer lesions, and those receiving conventional balloon dilation alone were most likely to undergo stenting. Conclusion: In a real-world patient population with long, complex femoropopliteal lesions, use of the FLEX VP System as vessel preparation for angioplasty improved acute outcomes compared to historical controls. The rate of provisional stenting was low, and no serious vessel complications were observed.

Abstract
Despite recent advances in endovascular therapy of lower extremity atherosclerotic disease, mainly driven through drug eluting balloon angioplasty, treatment of complex lesions remains challenging. Drug-eluting balloons work less well in heavily calcified lesions and in particular long lesions often require bail-out stenting. Lesion preparation, as a stand-alone treatment or before delivering antiproliferative therapy or scaffolding, has gained increased recognition in recent years. Focal force or other specialty balloons are designed to prepare complex lesions to improve acute technical success and, ideally, long term patency of the vessel. There are numerous dedicated balloons on the market that use different modes of action to prepare the lesions. The current review focuses on mechanistic insights and the evidence behind those specialty balloons.

Abstract
OBJECTIVE Although percutaneous transluminal angioplasty is an effective therapy against vascular access failure in hemodialysis patients, recurrent stenosis imposes enormous burden for hemodialysis patients. A nitinol scoring element-equipped helical balloon catheter (AngioSculpt®) has been altered the landscape for treating several vascular diseases. It is not, however, fully elucidated whether AngioSculpt for advanced vascular access stenosis, difficult to expand by conventional balloons, successfully provides bailout angioplasty. Here, we report our cases whose intradialytic venous pressure significantly improved after percutaneous transluminal angioplasty without any serious adverse complications using AngioSculpt. PATIENTS AND METHODS Among patients undergoing hemodialysis in Masuko Memorial Hospital, 16 cases with resistant and recurrent vascular access stenosis underwent AngioSculpt (diameter 6 mm, total length 4 cm) angioplasty. We simultaneously measured the average venous pressures during hemodialysis before and after percutaneous transluminal angioplasty. RESULTS The average outflow vessel stenosis rate was 73.0 ± 11.3% before AngioSculpt intervention. Fully enlarged vessels were observed by expanding vessels at maximum pressure of 14 atm in all cases without any complications including vascular ruptures. Their intradialytic venous pressures decreased from 181.8 ± 39.2 mmHg to 150.5 ± 39.3 mmHg ( p < 0.0001). CONCLUSION AngioSculpt may provide a promising option for treating hemodialysis patients with severely advanced vascular access stenosis, who would otherwise need repeated vascular access surgeries and/or conventional percutaneous transluminal angioplasties.

Abstract
Abstract. Background: Treatment of calcified femoropopliteal lesions remains challenging, even in the era of drug-eluting balloon angioplasty. Lesion recoil and dissections after standard balloon angioplasty in calcific lesions often require subsequent stent implantation. Additionally, poor patency rates in calcified lesions despite the use of drug-eluting balloons may be due to the limited penetration depth of the antiproliferative drug in the presence of vascular calcium deposits. Therefore, preparation of calcified lesions with the AngioSculpt™ scoring balloon might be a valuable option either as a stand-alone treatment, followed by drug-eluting balloon angioplasty or prior to subsequent stent deployment. Patients and methods: In this retrospective, single centre registry, 124 calcified femoropopliteal lesions were treated in 101 subsequent patients. All patients were treated with scoring balloon angioplasty, either alone, in combination with drug-eluting balloons, or prior to stent deployment. The primary outcome was safety and technical success during the index procedure as well as patency at six and 12 months, as evaluated by duplex sonography. Results: Successful scoring was safely performed in all 124 lesions with the AngioSculpt™ balloon. Overall primary patency after 12 months was 81.2 %. Patency rates did not differ significantly between the three treatment strategies. Degree of calcification did not predict patency. Improved clinical outcomes (Rutherford-Becker class and ankle-brachial index) were also observed in the study cohort. Conclusions: Preparation with the AngioSculpt™ scoring balloon offers a safe and valuable treatment option for calcified femoropopliteal lesions.

Abstract
Percutaneous therapies for peripheral artery disease continue to evolve with new techniques and devices. Although guidelines-recommended therapies have impacted cardiovascular morbidity and mortality, endovascular interventions have been shown to reduce limb pain, improve quality of life, and prolong walking distance for those with claudication and to reduce amputation rates among those with critical limb ischemia. Novel devices such as drug-eluting stents and drug-coated balloons have improved patency for moderate-length lesions, whereas others allow treatment of heavily calcified and tortuous segments. New adjunctive devices to cross lesions and reduce or modify associated plaque have also been developed, although level 1 data regarding their efficacy are sparse. There has also been a better mechanistic understanding of lower extremity endovascular treatment using tools such as intravascular ultrasound. This information has highlighted the need for better stent size selection for the femoropopliteal arterial segments and larger balloon diameters for the tibial arteries. Moreover, a wound perfusion approach with direct in-line flow, the so-called angiosome approach, and reconstruction of the pedal loop have been advocated for improved wound healing. Technical advances such as the tibiopedal access and reentry methods have allowed crossing of lesions that were considered no option for the endovascular approach in the past. Collectively, there has been increased awareness, interest, and commitment by various specialty societies and organizations to advance the treatment of peripheral artery disease and critical limb ischemia. This is also evident by the recent coalition of 7 professional societies and organizations that represented >150 000 allied health professionals and millions of patients with peripheral artery disease at the 2015 Centers for Medicaid and Medicare Services Medicare Evidence Development and Coverage Analysis Committee meeting. The percutaneous therapies for peripheral artery disease continue to evolve with longer follow-up with randomized data and larger prospective registries. In the future, it is hopeful that we will treat the lower extremity arteries according to segments, taking into account plaque morphology, luminal versus subintimal crossing, location, and stenotic versus occlusive disease. Until then, we must identify the most cost-effective, efficacious, and safe treatment for each patient. The goal of this article is to aid the practicing vascular specialist consider the optimal choices for the management of patients with vascular disease.

Abstract
PURPOSE To evaluate the safety, feasibility, and effectiveness of cutting balloon angioplasty in the management of infrapopliteal bifurcation disease. METHODS Between November 2010 and March 2013, 23 patients (mean age 69.6±9.01 years, range 56-89; 16 men) suffering from critical limb ischemia were treated using cutting balloon angioplasty (single cutting balloon, T-shaped double cutting balloon, or double kissing cutting balloon technique) for 47 infrapopliteal artery bifurcation lesions (16 popliteal bifurcation and 9 tibioperoneal bifurcation) in 25 limbs. Follow-up consisted of clinical examination and duplex ultrasonography at 1 month and every 3 months thereafter. RESULTS All treatments were technically successful. No 30-day death or adverse events needing treatment were registered. No flow-limiting dissection was observed, so no stent implantation was necessary. The mean postprocedure minimum lumen diameter and acute gain were 0.28±0.04 and 0.20±0.06 cm, respectively, with a residual stenosis of 0.04±0.02 cm. Primary and secondary patency rates were estimated as 89.3% and 93.5% at 6 months and 77.7% and 88.8% at 12 months, respectively; 1-year primary and secondary patency rates of the treated bifurcation were 74.2% and 87.0%, respectively. The survival rate estimated by Kaplan-Meier analysis was 82.5% at 1 year. CONCLUSION Cutting balloon angioplasty seems to be a safe and effective tool in the routine treatment of short/ostial infrapopliteal bifurcation lesions, avoiding procedure-related complications, overcoming the limitations of conventional angioplasty, and improving the outcome of catheter-based therapy.
