RESUMEN

OBJECTIVE: Most surgeons employ an endovascular-first approach to the treatment of peripheral arterial disease (PAD), but controversy remains regarding the ideal interventions for the management of isolated popliteal artery disease (IPAD). Indeed, there are a paucity of data that compare outcomes of popliteal stents vs other peripheral vascular interventions (PVIs). The goal of this study was to evaluate outcomes of PVIs in IPAD. METHODS: The Vascular Study Group of New England database was queried for all IPAD PVIs performed for atherosclerotic occlusive disease from 2010 to 2021. Those with at least 1 year of follow-up data available were included for analysis. The primary endpoint was 1-year freedom from a composite target lesion (TL) treatment failure that included restenosis >50% on duplex, reintervention, or ipsilateral major amputation. RESULTS: We included 689 procedures performed on 634 patients. Of these, 250 (36.3%) were treated with plain balloons (POBA), 215 (31.2%) had stents, 170 (24.7%) had special balloons (drug-coated, cutting, or lithotripsy), and 54 (7.8%) atherectomies were performed. Stent placement was associated with lower freedom from TL treatment failure (72.6%) than special balloon (81.2%; P = .048) and atherectomy (88.9%; P = .012), but not POBA (76.8%; P = .293). On multivariable logistic regression, stents (odds ratio, 0.637; P = .021) and preoperative P2Y12 inhibitor therapy (odds ratio, 0.683; P = .048) were both associated with lower freedom from intervention failure. CONCLUSIONS: Popliteal stent placement is associated with a higher rate of TL treatment failure at 1 year when compared with other PVIs including special balloon angioplasty and atherectomy, but not POBA, and should therefore be avoided in favor of special balloons or atherectomy whenever feasible.

RESUMEN

OBJECTIVE: Popliteal access (PA) as an alternative to conventional femoral access has not been reported in the office-based catheter laboratory setting (OBL) and may be perceived to have higher risks. The purpose of this study is to evaluate the safety and efficacy of popliteal access for endovascular treatment of iliofemoral arterial occlusive disease in an OBL setting. METHODS: From 10/2018 - 10/2023 a total of 1,408 PAD interventions were performed in our OBL. A cohort of 27 popliteal access consecutive procedures for femoral and iliac artery occlusions were studied. All interventions were done using a micro-puncture needle under ultrasound guidance. All patients were discharged 1 hour after completion of the procedure. Indications for popliteal access were presence of aortoiliac stent/grafts, aorto-bifemoral or aortoiliac bypasses, difficult contralateral or antegrade femoral access, and flush superficial femoral artery (SFA) occlusions. Procedures were determined to be successful upon complete resolution of the target lesions and safety was measured peri-operatively and at 90-days. Patency was determined clinically, by arterial duplex, and by need for reintervention up to 2 years. RESULTS: 27 popliteal access procedures were performed in 25 patients (21 complete femoral artery occlusions, 6 severe stenosis). Iliac disease was present in 9. Indications for PA were existing aortoiliac stent graft 11, aorto-bifem-iliac bypass 4, non-crossable iliac occlusions 3, failed antegrade femoral access 4, flush SFA occlusion 3, and bilateral common femoral artery disease precluding access 2. TASC pre-op was B: 4, C: 4, D:19. Treatments included atherectomy/balloon angioplasty (BA) and stent 12, BA and stenting 4, atherectomy/BA 5, BA alone 6. Successful opening of occlusions occurred in 25/27 (92.5%). No complications or major adverse cardiac events (MACE) occurred except 1 asymptomatic small popliteal AV fistula. Of the 25 successful procedures duplex patency at 3, 6 & 12 months was 19/20 (95%), 11/15 (69.3%) & 11/13 (61%). Rutherford Classification improved from pre-op > 4 in 24/27 (89%) to post-op < 2 at 1 month in 23/23 (100%), 3 months in 19/20 (95%), 6 months in 11/15 (69.3%), 12 months in 11/13 (61%). Freedom from re-intervention at 3 months in 19/20 (95%), 6 months in 13/15 (86%), and 12 months in 12/13 (79%). CONCLUSIONS: Popliteal artery access for complex iliofemoral disease is safe and effective and should be considered as a valid alternative option in the OBL setting.

RESUMEN

OBJECTIVE: The recent publication of randomized trials comparing open bypass surgery to endovascular therapy in patients with chronic limb-threatening ischemia, namely, Best Endovascular vs Best Surgical Therapy in Patients with Critical Limb Ischemia (BEST-CLI) and Bypass versus Angioplasty in Severe Ischaemia of the Leg-2 (BASIL-2), has resulted in potentially contradictory findings. The trials differed significantly with respect to anatomical disease patterns and primary end points. We performed an analysis of patients in BEST-CLI with significant infrapopliteal disease undergoing open tibial bypass or endovascular tibial interventions to formulate a relevant comparator with the outcomes reported from BASIL-2. METHODS: The study population consisted of patients in BEST-CLI with adequate single segment saphenous vein conduit randomized to open bypass or endovascular intervention (cohort 1) who additionally had significant infrapopliteal disease and underwent tibial level intervention. The primary outcome was major adverse limb event (MALE) or all-cause death. MALE included any major limb amputation or major reintervention. Outcomes were evaluated using Cox proportional regression models. RESULTS: The analyzed subgroup included a total of 665 patients with 326 in the open tibial bypass group and 339 in the tibial endovascular intervention group. The primary outcome of MALE or all-cause death at 3 years was significantly lower in the surgical group at 48.5% compared with 56.7% in the endovascular group (P = .0018). Mortality was similar between groups (35.5% open vs 35.8% endovascular; P = .94), whereas MALE events were lower in the surgical group (23.3% vs 35.0%; P<.0001). This difference included a lower rate of major reinterventions in the surgical group (10.9%) compared with the endovascular group (20.2%; P = .0006). Freedom from above ankle amputation or all-cause death was similar between treatment arms at 43.6% in the surgical group compared with 45.3% the endovascular group (P = .30); however, there were fewer above ankle amputations in the surgical group (13.5%) compared with the endovascular group (19.3%; P = .0205). Perioperative (30-day) death rates were similar between treatment groups (2.5% open vs 2.4% endovascular; P = .93), as was 30-day major adverse cardiovascular events (5.3% open vs 2.7% endovascular; P = .12). CONCLUSIONS: Among patients with suitable single segment great saphenous vein who underwent infrapopliteal revascularization for chronic limb-threatening ischemia, open bypass surgery was associated with a lower incidence of MALE or death and fewer major amputation compared with endovascular intervention. Amputation-free survival was similar between the groups. Further investigations into differences in comorbidities, anatomical extent, and lesion complexity are needed to explain differences between the BEST-CLI and BASIL-2 reported outcomes.

RESUMEN

Diabetes related foot complications have become a major cause of morbidity and are implicated in most major and minor amputations globally. Approximately 50% of people with diabetes and a foot ulcer have peripheral artery disease (PAD) and the presence of PAD significantly increases the risk of adverse limb and cardiovascular events. The International Working Group on the Diabetic Foot (IWGDF) has published evidence based guidelines on the management and prevention of diabetes related foot complications since 1999. This guideline is an update of the 2019 IWGDF guideline on the diagnosis, prognosis and management of peripheral artery disease in people with diabetes mellitus and a foot ulcer. For this guideline the IWGDF, the European Society for Vascular Surgery and the Society for Vascular Surgery decided to collaborate to develop a consistent suite of recommendations relevant to clinicians in all countries. This guideline is based on three new systematic reviews. Using the Grading of Recommendations, Assessment, Development, and Evaluation framework clinically relevant questions were formulated, and the literature was systematically reviewed. After assessing the certainty of the evidence, recommendations were formulated which were weighed against the balance of benefits and harms, patient values, feasibility, acceptability, equity, resources required, and when available, costs. Through this process five recommendations were developed for diagnosing PAD in a person with diabetes, with and without a foot ulcer or gangrene. Five recommendations were developed for prognosis relating to estimating likelihood of healing and amputation outcomes in a person with diabetes and a foot ulcer or gangrene. Fifteen recommendations were developed related to PAD treatment encompassing prioritisation of people for revascularisation, the choice of a procedure and post-surgical care. In addition, the Writing Committee has highlighted key research questions where current evidence is lacking. The Writing Committee believes that following these recommendations will help healthcare professionals to provide better care and will reduce the burden of diabetes related foot complications.

RESUMEN

Randomized clinical trials failed to show additional benefit of renal artery stenting on top of medical therapy. Instead of writing an obituary on renal artery stenting, we try to explain these disappointing results. A transstenotic pressure gradient is needed to reduce renal perfusion and to activate the renin-angiotensin-aldosterone system. In only a minority of patients included in trials, a transstenotic pressure gradient is measured and reported. Like the coronary circulation, integration of physiological lesion assessment will allow to avoid stenting of non-significant lesions and select those patients that are most likely to benefit from renal artery stenting. Renal artery interventions are associated with peri-procedural complications. Contemporary techniques, including radial artery access, no-touch technique to engage the renal ostium and the use of embolic protection devices, will minimize procedural risk. Combining optimal patient selection and meticulous technique might lead to a netto clinical benefit when renal artery stenting is added to optimal medical therapy.

RESUMEN

INTRODUCTION: Chronic internal carotid artery occlusion (CICAO) is a common cause of stroke and ischemia recurrence. An increasing number of reports have highlighted the potential of hybrid surgery for treating CICAO. There are few studies, specifically nonrandomized controlled trials, on the safety and effectiveness of hybrid surgery for the treatment of CICAO, so in this study, we hypothesized that hybrid surgery would be safe, have an acceptable complication rate and a high success rate. METHODS: MEDLINE, Embase, Cochrane Library, and Web of Science databases were searched for relevant studies published up to January 30, 2023. The primary endpoint was recanalization rates of occluded vessels, and the secondary endpoint was perioperative death and procedure-related complications. Subgroup analysis focused on the recanalization rates of endovascular intervention (EI) and hybrid surgery, as well as the rates of recanalization below the clinoid segment and at the clinoid segment and beyond. The follow-up visit was conducted at least 3 months after surgery, and stenosis or occlusion recurrence was confirmed by review of CTA or DSA scan. RESULTS: The databases were searched and 1,709 records were identified, of which 16 articles were used in the meta-analysis, and 464 CICAO patients with complete data who underwent hybrid surgery were enrolled. Hybrid surgery was associated with higher success rates (RD = 0.87, 95% CI [0.84-0.91], p < 0.00001) than EI (OR = 4.71, 95% CI [2.32-9.56], p < 0.0001). The procedural success rate in the below-clinoid segment group was significantly higher than that in the clinoid segment and beyond group (OR = 13.76, 95% CI [5.31-35.66], p < 0.00001). The total periprocedural complication rate was low (RD = 0.11, 95% CI [0.07-0.15], p < 0.00001 and RD = 0.04, 95% CI [0.00-0.07], p = 0.03). Target vessel restenosis or reocclusion occurred in 35 patients (8%) during the follow-up period (RD = 0.08, 95% CI [0.04-0.12], p < 0.0001). CONCLUSION: Hybrid surgery is the combination of the advantages of open surgery and EI, has a high success rate and a low risk of recurrence of stenosis and occlusion in the long term. Randomized controlled trials on hybrid surgery for internal carotid artery occlusion are necessary.

RESUMEN

OBJECTIVE: There is great variability in the treatment of chronic limb-threatening ischemia, including the practice paradigm, vascular provider specialty, devices utilized, and experience with advanced open and/or endovascular treatments, among other factors. Our unique practice consists of patient-centered, clinically oriented Interventional Radiologists and Vascular Surgeons, with treatments being performed in Office Interventional Suites (OIS), Ambulatory surgery center (ASC), and hospital inpatient/outpatient settings. We evaluate our results, centered on major amputation rates while comparing case complexity and rates with previously published data. METHODS: A retrospective review was performed of all Rutherford 4, 5, and 6 patients who underwent treatment in our practice from 2015 to 2021. Baseline patient characteristics, complexity of lesions, and major amputation rates were collected. Patients with more complex diseases or requiring re-interventions were openly discussed in multidisciplinary fashion to determine the group's approach to revascularization. Limb salvage, clinically driven target lesion revascularization (TLR), repeat interventions, length of follow-up, and mortality were assessed. RESULTS: Treatment was performed in 829 limbs in 351 females and 478 males, with chronic limb-threatening ischemia. Of the 829 cases, 541 cases had at least 1 chronic total occlusion (CTO), including 115 limbs with 2 CTOs and 24 limbs with 3 CTOs with 63.5% of cases requiring multilevel intervention. One year mortality rate was 6.2% with a major lower extremity amputation rate of 2.3% with a mean length of follow-up of 22.3 months. One-year freedom from clinically driven TLR rate was 78.7% with repeat intervention in 163 cases within 12 months. Over the course of the study, within the femoropopliteal stent subset, there was a significant increase in time to reintervention when newer stent technologies were utilized such as woven nitinol and drug-eluting technology (p=0.03). The overall 1-year amputation-free survival (AFS) was 91.5. CONCLUSIONS: Multidisciplinary approach with surgical and endovascular treatment may provide patients with the best chance of AFS. CLINICAL IMPACT: Real world practice of critical limb-threatening ischemia in a multidisciplinary practice demonstrates favorable outcomes for patients with the best reported one year major amputation free survival in a population this large. A strong clinical practice based on close routine follow up and arterial duplex monitoring is a major contributing factor, as well as utilization of the latest technology in drug eluting stents and drug coated balloons for best patient outcomes. We hope this study provides other practices with a guideline for establishing or modifying their practice to attain the best procedural and clinical outcomes.

RESUMEN

OBJECTIVE: Endovascular technology innovation requires rigorous evaluation in high quality randomised controlled trials (RCTs). However, due to numerous methodological challenges, RCTs evaluating endovascular interventions are complex and potentially difficult to design, conduct, and report. This systematic review aimed to assess the quality of reporting of RCTs for endovascular interventions for lower limb peripheral arterial disease (PAD). DATA SOURCES AND REVIEW METHODS: A systematic review of Medline, Embase, and the Cochrane Library databases from inception to December 2021 was performed to identify RCTs including participants with PAD undergoing any infrainguinal lower limb endovascular intervention. Study data were extracted and assessed against the Consolidating Standards of Reporting Trials extension for Non-Pharmacological Treatments (CONSORT-NPT) and the Template for Intervention Description and Replication (TIDieR) checklists. Descriptive statistics were used to summarise general study details and reporting standards of the trials. RESULTS: After screening 6 567 abstracts and 526 full text articles, 112 eligible studies were identified, reporting on 228 different endovascular devices and techniques. Details judged sufficient to replicate the investigated intervention were provided for 47 (21%) interventions. It was unclear whether the description was reported with sufficient details in a further 56 (24%), and the description was judged inadequate in 125 (55%). Any intervention descriptions were provided for 184 (81%), with variable levels of detail (some in 134 [59%] and precise in 50 [22%]). Standardisation of intervention or some aspect of this was reported in 25 (22%) trials, but only one specified that adherence to the study protocol would be monitored. CONCLUSION: The quality of the reporting standards of RCTs investigating lower limb endovascular treatments is severely limited because the interventions are poorly described, standardised, and reported. PROSPERO registration number: CRD42022288214.

RESUMEN

BACKGROUND: Mechanical thrombectomy represents a mainstay of management for acute ischemic stroke in the setting of large vessel occlusion. However, there are no clinical practice guidelines defining the role of thrombectomy at the extremes of age. In this scoping review, we aimed to summarize the existing medical and neurosurgical literature pertaining to mechanical thrombectomy in nonagenarians. The PubMed database was queried using the following terms and relevant citations assessed: "thrombectomy nonagenarian," "thrombectomy age 90," "stroke nonagenarian," and "ischemic stroke thrombectomy." Common measurable outcomes, including mortality, modified Rankin scale (mRS) score, and thrombolysis in cerebral infarction (TICI) scale score, were utilized to compare results. SUMMARY: Thrombectomy was shown to improve functional outcomes in all eight of the studies included in the analysis. Mortality was assessed in only two reported studies, and thrombectomy was shown to provide a mortality benefit in 1 study among patients for whom first-pass reperfusion was achieved. Other outcomes of reported interest included greater early neurologic recovery at discharge and improved functional outcomes at 90 days among nonagenarians who underwent thrombectomy as compared to those who received thrombolytic therapy alone. Nonagenarians with good functional status at baseline were the most likely to have favorable outcomes. KEY MESSAGES: Mechanical thrombectomy improves outcomes among nonagenarians presenting with acute ischemic stroke due to large vessel occlusion. Further large-scale prospective studies are warranted to optimize patient selection and develop clinical practice guidelines specific to this important patient demographic.

RESUMEN

BACKGROUND: Patients with symptomatic chronic internal carotid artery occlusion (ICAO) face a high risk of recurrent stroke despite receiving aggressive medical therapy. This study aimed to evaluate the effectiveness and safety of hybrid surgery in treating symptomatic chronic ICAO. METHODS: This retrospective case series was conducted at a single center. From January 2019 to December 2022, patients with symptomatic chronic ICAO who underwent hybrid surgery were included. We collected baseline data, lesion characteristics, revascularization rates, perioperative complications, and follow-up outcomes. RESULTS: The study enrolled 27 patients, comprising 22 males and 5 females, with symptomatic chronic ICAO. The hybrid surgery achieved a technical success rate of 100% for revascularization (n = 27), with a perioperative complication rate of 14.8% (n = 4). Following a median follow-up of 6.0 months (IQR, 4-10), 21 patients underwent a DSA or CT angiography reexamination, confirming a vascular patency rate of 90.5% (n = 19). One patient required surgery for severe in-stent restenosis, and another experienced asymptomatic occlusion. Clinical follow-ups were conducted for all 26 patients; no new strokes were reported in the qualifying artery territory, with 13 patients scoring 0, 12 scoring 1, and 1 scoring 2 on the mRS. CONCLUSION: Although hybrid surgery represent a promising option for treating chronic ICAO, they are also associated with a relatively high incidence of treatment-related complications. The application of composite surgery should be based on standardized technical guidelines and the careful selection of patients who are genuinely at high risk for recurrent strokes.

RESUMEN

Emergency endovascular and percutaneous urological interventions encompass various diagnostic and therapeutic procedures to address various genitourinary conditions. These urological interventions are life-saving in addressing complications following biopsy, post-nephrectomy, post-transplant, and post-trauma. Compared to other surgical fields, there are relatively fewer urological emergencies. However, they require prompt radiological diagnosis and urgent interventions. This pictorial essay emphasizes various urological emergencies and urgent interventional management.

RESUMEN

BACKGROUND: The use of stents to treat un-ruptured intracranial aneurysms was first approved in the year 2002 in the United States as a Humanitarian Device Exemption. Antiplatelet therapy is mandatory following stent placement. Dual antiplatelet therapy (DAPT) with aspirin and clopidogrel has been the first line agents for the prevention of thromboembolic events following neuro-endovascular procedures. However, clopidogrel hypo-responsiveness has often been observed. In this analysis, we aimed to systematically compare one year clinical outcome of DAPT with the Novel Ticagrelor plus Aspirin versus Clopidogrel plus Aspirin for Endovascular Intervention of patients with Intracranial Aneurysm. METHODS: Online electronic databases were searched from June 2023 till July 2023 for relevant studies which compared DAPT with ticagrelor or clopidogrel for endovascular intervention in patients with intracranial aneurysm. The endpoints which were analyzed were classified into thromboembolic and hemorrhagic events. A fixed and a random effect statistical model were used during data analysis respectively. Risk ratio (RR) with 95 % confidence interval (CI) was used to represent the data following analysis. RESULTS: Five studies with a total number of 893 participants were included in this analysis. Three hundred and fifty eight (358) participants were assigned to the ticagrelor group whereas 535 participants were assigned to clopidogrel group. Participants' enrollment period ranged from the year 2009 to 2019. Our results showed that during a mean follow-up time period of one year, DAPT with ticagrelor was associated with significantly lower thromboembolic events with RR: 0.33, 95 % CI: 0.16 - 0.68; P = 0.003. In addition, at one year, DAPT with ticagrelor was not associated with any increase in hemorrhagic events (RR: 0.66, 95 % CI: 0.29 - 1.50; P = 0.32) when compared to DAPT with clopidogrel. CONCLUSION: At one year, DAPT with ticagrelor was associated with significantly lower thromboembolic events without any increase in hemorrhagic events when compared to clopidogrel associated DAPT for endovascular intervention of patients with intracranial aneurysm. However, even though ticagrelor-associated DAPT use appeared to be more effective and safe, this hypothesis should only be confirmed in larger upcoming trials.

RESUMEN

The Taiwan Society of Cardiology (TSOC) and Taiwan Society of Plastic Surgery (TSPS) have collaborated to develop a joint consensus for the management of patients with advanced vascular wounds. The taskforce comprises experts including preventive cardiologists, interventionists, and cardiovascular and plastic surgeons. The consensus focuses on addressing the challenges in diagnosing, treating, and managing complex wounds; incorporates the perfusion evaluation and the advanced vascular wound care team; and highlights the importance of cross-disciplinary teamwork. The aim of this joint consensus is to manage patients with advanced vascular wounds and encourage the adoption of these guidelines by healthcare professionals to improve patient care and outcomes. The guidelines encompass a range of topics, including the definition of advanced vascular wounds, increased awareness, team structure, epidemiology, clinical presentation, medical treatment, endovascular intervention, vascular surgery, infection control, advanced wound management, and evaluation of treatment results. It also outlines a detailed protocol for assessing patients with lower leg wounds, provides guidance on consultation and referral processes, and offers recommendations for various wound care devices, dressings, and products. The 2024 TSOC/TSPS consensus for the management of patients with advanced vascular wounds serves as a catalyst for international collaboration, promoting knowledge exchange and facilitating advancements in the field of advanced vascular wound management. By providing a comprehensive and evidence-based approach, this consensus aims to contribute to improved patient care and outcomes globally.

RESUMEN

OBJECTIVE: Antiplatelet agents are commonly used after peripheral endovascular intervention (PVI). However, the effect of full-dose anticoagulation on outcomes after PVI is not well-established. We sought to investigate whether full-dose anticoagulation after PVI is associated with adverse events. METHODS: We utilized the Vascular Quality Initiative to study patients undergoing index PVI for claudication (2010-2019), stratified by the presence or absence of an anticoagulant on discharge. The primary outcomes were 2-year patency, major adverse limb events (MALE), and mortality. We built a propensity score adjusting for comorbidities and employed inverse probability weighting to estimate the association of anticoagulation with outcomes. RESULTS: We identified 26,240 patients; 9.1% were discharged on an anticoagulant. Patients receiving any anticoagulation had a significantly higher risk of mortality (adjusted hazard ratio [aHR], 1.61; 95% confidence interval [CI], 1.35-1.92), but not MALE, or patency loss. Patients receiving a vitamin K antagonist had a significantly higher risk of patency loss (aHR, 1.32; 95% CI, 1.09-1.60), MALE (aHR, 1.33; 95% CI, 1.13-1.57), and mortality (aHR, 1.46; 95% CI, 1.27-1.69). Patients on an oral Factor Xa inhibitors had a significantly lower risk of patency loss (aHR, 0.61; 95% CI, 0.41-0.93) but increased mortality (aHR, 1.51; 95% CI, 1.19-1.92). CONCLUSIONS: Therapeutic anticoagulation after PVI is associated with higher risk of all-cause mortality. Although oral Factor Xa inhibitors are associated with decreased risk of patency loss, vitamin K antagonists are associated with higher risk of patency loss, MALE, and death. Further prospective studies are necessary to study the safety and efficacy of full-dose anticoagulation after PVI.

RESUMEN

Diabetes related foot complications have become a major cause of morbidity and are implicated in most major and minor amputations globally. Approximately 50% of people with diabetes and a foot ulcer have peripheral artery disease (PAD) and the presence of PAD significantly increases the risk of adverse limb and cardiovascular events. The International Working Group on the Diabetic Foot (IWGDF) has published evidence based guidelines on the management and prevention of diabetes related foot complications since 1999. This guideline is an update of the 2019 IWGDF guideline on the diagnosis, prognosis, and management of peripheral artery disease in people with diabetes mellitus and a foot ulcer. For this updated guideline, the IWGDF, the European Society for Vascular Surgery, and the Society for Vascular Surgery decided to collaborate to develop a consistent suite of recommendations relevant to clinicians in all countries. This guideline is based on three new systematic reviews. Using the Grading of Recommendations, Assessment, Development and Evaluation framework clinically relevant questions were formulated, and the literature was systematically reviewed. After assessing the certainty of the evidence, recommendations were formulated which were weighed against the balance of benefits and harms, patient values, feasibility, acceptability, equity, resources required, and when available, costs. Through this process five recommendations were developed for diagnosing PAD in a person with diabetes, with and without a foot ulcer or gangrene. Five recommendations were developed for prognosis relating to estimating likelihood of healing and amputation outcomes in a person with diabetes and a foot ulcer or gangrene. Fifteen recommendations were developed related to PAD treatment encompassing prioritisation of people for revascularisation, the choice of a procedure and post-surgical care. In addition, the Writing Committee has highlighted key research questions where current evidence is lacking. The Writing Committee believes that following these recommendations will help healthcare professionals to provide better care and will reduce the burden of diabetes related foot complications.

RESUMEN

OBJECTIVE: The prevalence of chronic limb-threatening ischemia (CLTI) and poor health outcomes are high in Germany. Serious consequences of CLTI such as amputation and mortality can be effectively prevented by the early use of evidence-based therapeutic measures such as endovascular intervention. We have developed a cost-utility analysis to compare endovascular intervention with bare metal stents (BMSs) and endovascular intervention after conservative treatment from the German payer perspective. METHODS: A Markov model, with a 5-year time horizon and seven states, was developed: (1) intervention, (2) stable 1, (3) major amputation, (4) reintervention, (5) stable 2, (6) care, and (7) all-cause death. Transition probabilities were obtained by pooling the outcomes from multiple clinical studies. The costs were estimated using data from the German diagnosis-related group system, the German rehabilitation fund, and related literature. Health-state utilities were obtained from the reported data. The primary outcomes were the quality-adjusted life-years (QALYs) and costs. RESULTS: Early BMS intervention after 5 years resulted in a cost of €23,913 and an increase of 2.5 QALYs per patient, and endovascular intervention with BMS after conservative treatment after 5 years resulted in a cost of €18,323 and an increase of 2 QALYs per patient. The incremental cost-effectiveness ratio was €12,438. The number of major amputations was reduced by 6%. The results of the structural, deterministic, and probabilistic sensitivity analyses were robust. CONCLUSIONS: Early endovascular intervention with BMS resulted in more QALYs and a reduced risk of major amputation for early-stage CLTI patients. Our results showed that early endovascular intervention is very cost-effective according to World Health Organization recommended cost-effectiveness thresholds. However, the clinical decision regarding the use of early endovascular intervention should be determined by individual patient-level eligibility and the physician's judgment.

RESUMEN

Below-the-knee (BTK) pseudoaneurysms that occur after endovascular therapy (EVT) and result in delayed rupture have rarely been reported. In this report, we present a rare case of an 86-year-old man with chronic limb-threatening ischemia who developed delayed rupture of an idiopathic pseudoaneurysm of the peroneal artery (PA) following EVT. The PA chronic total occlusion (CTO) was successfully crossed using a guidewire via an antegrade approach, however, subintimal crossing was confirmed by intravascular ultrasound. Balloon angioplasty was then performed using an appropriately sized balloon, resulting in successful recanalization of the PA CTO with minor dissection and no complications. Postoperatively, the patient's condition was stable until he suddenly complained of right calf pain 10 days after EVT. Computed tomography revealed a rupture of the PA pseudoaneurysm. Urgent angiography revealed two pseudoaneurysms, one saccular and the other spindle-shaped. The ruptured saccular aneurysm was successfully excluded through coil embolization and stent graft placement. To the best of our knowledge, this is the first reported case of delayed rupture of a BTK pseudoaneurysm following EVT. Balloon angioplasty in the subintimal space can lead to the formation of a pseudoaneurysm and its delayed rupture.

RESUMEN

A 67-year-old male patient was admitted with an enormous twisted thoracoabdominal aortic aneurysm (TAAA) with multiple branch arteries stenosis and occlusion. Three-dimensional (3D) printing technology combined with mechanics was used for developing a transparent model of lesion to simulate the segment of diseased aorta. A stent graft was deployed in the 3D model to make a physician-modified stent graft (PMSGs) on table. The locations of the opening of branches were marked twice during operation. The PMSG was successfully deployed during the surgery and repaired the TAAA, with no endoleak and all the branched arteries patency in follow-up. This technique could offer precision individualized therapy and could simplify the procedure process greatly.

RESUMEN

BACKGROUND: Balloon angioplasty (BA), including drug-coated balloons (DCBs) and percutaneous transluminal angioplasty (PTA), has traditionally been used to treat femoral-popliteal lesions. However, in recent years, atherectomy (ATH) has been proposed as a complementary approach. To assess the effectiveness of ATH compared with BA alone in patients with femoral-popliteal artery lesions, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS: We included RCTs that focused on patients with femoral-popliteal artery lesions and reported data on the use of ATH and BA therapy. Two reviewers conducted a literature search, refined the data, and assessed the risk of bias. RESULTS: We included a total of 6 RCTs involving 399 patients with femoral-popliteal artery lesions. The use of ATH in combination with BA appeared to improve the patency rate at 12 months (odds ratio [OR]=2.04, 95% confidence interval [CI]=1.14-3.62). In addition, ATH with BA was associated with lower major amputation rates (MD=2.01, 95% CI=0.06-0.77, p=0.02) and a decreased likelihood of bailout stenting (OR=0.07, 95% CI=0.02-0.25, p=0.001). However, there were no statistically significant differences between the groups in terms of target lesion revascularization (TLR) at 12 months, major adverse cardiovascular events (MACEs), and distal embolization events. In addition, we performed subgroup analysis for different ATH devices and BA types. CONCLUSIONS: Based on this meta-analysis, it can be concluded that the use of ATH in combination with BA is a safe and effective method for treating femoral-popliteal artery lesions. In addition, the patency rate at 1 year is superior to treatment with BA alone. Atherectomy also reduces the likelihood of amputation and bailout stenting. Clinicians should consider these findings when designing future RCTs and developing clinical practice guidelines. CLINICAL IMPACT: This meta-analysis summarises a number of existing studies to advance understanding of the atherectomy devices and to reveal its potential. This new technique, when compared with drug coated balloon, shows the possibility of obtaining better clinical outcomes in femoro-popliteal lesions than drug-coated balloon alone, such as higher 12-month primary patency rates as shown in some studies. Currently, it is important to consider the appropriate technology applicable for individualised treatment. atherectomy devices seem to provide clinicians with additional options in clinical practice and to benefit patients in the future. This requires more high quality studies to explore the role and benefits of atherectomy devices in femoro-popliteal lesions.
