Abstract
Patients with chronic limb-threatening ischemia, the terminal stage of peripheral artery disease, are frequently afflicted by below-the-knee disease. Although all patients should receive guideline-directed medical therapy, restoration of inline flow is oftentimes necessary to avoid limb loss. Proper patient selection and proficiency in endovascular techniques for below-the-knee revascularization are intended to prevent major amputation and promote wound healing. This review, a consensus among an international panel of experienced operators, provides guidance on these challenges from an endovascular perspective and offers techniques to navigate this complex disease process.

Abstract
Peripheral artery disease (PAD) is associated with high rates of readmission following endovascular interventions and contributes to a significant hospital readmission burden. Quality metrics like hospital readmissions affect hospital performance, but must adjust to local trends. Our primary goal was to evaluate risk factors and readmission rates post-percutaneous peripheral intervention in a US-Mexico border city, at a single tertiary university hospital. We performed a retrospective review of patients with PAD undergoing first time peripheral intervention from July 2015 to June 2020. Among 212 patients, 58% were readmitted with median 235-day follow-up (inter-quartile range (IQR) 42-924); 35.3% of readmissions occurred within 30 days, and 30.2% of those were within 7 days. Median time to readmission was 62 days. Active smokers had 84% higher risk of readmission (hazard ratio (HR) 1.84, 95% CI 1.23-2.74, P < .01). Other significant factors noted were insurance status-Medicaid or uninsured (HR 1.94, 95% CI 1.22-3.09), prior amputation (HR 1.69, 95% CI 1.13-2.54), heart failure, both preserved (HR 4.35, 95% CI 2.07-9.16) and reduced ejection fraction (HR 1.88, 95% CI 1.14-3.10). Below the knee, interventions were less likely to be readmitted (adjusted HR .64, 95% CI 0.42-.96). Readmission rates were unrelated to medication adherence.

Abstract
An increasing proportion of patients with chronic limb-threatening ischemia are older and have multiple comorbidities, including diabetes and renal failure. For those who are not candidates for a surgical bypass, this set of patients presents a challenge to vascular surgeons and interventionalists owing to the complex below-the-knee and increasingly below-the-ankle disease pattern that can fail traditional approaches for endovascular intervention. Two techniques, the retrograde pedal access and the pedal-plantar loop technique, can be useful in these settings and in skilled hands can be used safely, with a high technical success rate. In patients with chronic limb-threatening ischemia who are not candidates for a single-segment saphenous vein bypass, the retrograde pedal access technique can be used not only in the setting of failed antegrade treatment, but also primarily when faced with a difficult groin or as an adjunct during a planned antegrade-retrograde intervention. The pedal plantar loop technique allows for retrograde access to tibial vessels without retrograde vessel puncture and additionally offers the ability to treat the pedal-plantar arch, which may have added benefit in wound healing. We describe the tips and tricks for these two techniques used in our limb salvage practice.

Abstract
The global vascular guideline proposed a novel anatomical classification of infra-malleolar (IM) arterial lesions. We aimed to investigate the association of IM classification with clinical outcomes in patients with chronic limb-threatening ischemia (CLTI) due to isolated infrapopliteal (IP) lesions. We retrospectively analyzed 509 limbs with tissue loss in 357 patients due to isolated IP lesions who underwent endovascular therapy (EVT) between April 2010 and December 2018. The primary outcome was 1-year wound healing rate. The association of patient and anatomic characteristics with non-healing was evaluated using Cox proportional hazards regression analysis. The 1-year cumulative wound healing rate was 59.7%. Multivariable analysis demonstrated that IM grade 2 (hazard ratio [HR], 1.41; P = .044), non-ambulatory status (HR, 1.49; P = .008), hemodialysis (HR, 1.37; P = .020), left ventricular ejection fraction < 50% (HR, 1.72; P = .030), and wound, ischemia, and foot infection (WIfI) classification 4 (HR, 1.33; P = .032) were significantly associated with non-healing, whereas no below-the-ankle (BTA), below-the-knee (BTK) runoff, and Global Limb Anatomic Staging System (GLASS) IP grade had no statistically significant association with non-healing. Global Limb Anatomic Staging System IM grade 2 was an independent risk factor for wound healing in patients who underwent EVT with CLTI due to isolated IP disease.

Abstract
C-arm systems with digital flat-panel detectors are used in interventional radiology and hybrid operating rooms for visualizing and performing interventions on three-dimensional structures. Advances in C-arm technology have enabled intraoperative quantitative perfusion imaging with these scanners. This systematic review provides an overview of flat-panel detector C-arm techniques for quantifying perfusion, their clinical applications, and their validation. A systematic search was performed for articles published between January 2000 and October 2022 in which a flat-panel detector C-arm technique for quantifying perfusion was compared with a reference technique. Nine articles were retrieved describing two techniques: two-dimensional perfusion angiography (n = 5) and dual-phase cone beam computed tomography perfusion (n = 4). A quality assessment revealed no concerns about the applicability of the studies. The risk of bias was relatively high for the index and reference tests. Both techniques demonstrated potential for clinical application; however, weak-to-moderate correlations were reported between them and the reference techniques. In conclusion, both techniques could add new possibilities to treatment planning and follow-up; however, the available literature is relatively scarce and heterogeneous. Larger-scale randomized prospective studies focusing on clinical outcomes and standardization are required for the full understanding and clinical implementation of these techniques.

Abstract
OBJECTIVE Demonstrate that simplified ERICVA (Valladolid Critical Limb Ischaemia Risk Scale) is useful in predicting amputation in chronic limb-threatening ischemia (CLI) after one year of revascularization. METHODS A retrospective cohort study was performed. We analyzed the medical records of 93 patients over the age of 35 with the diagnosis of CLI who were treated in the Department of Internal Medicine, Orthopedics or in the Cardiovascular Surgery Unit of the Víctor Lazarte Echegaray Hospital and the High Complexity Virgen de La Puerta Hospital during the period 2015-2018. The simplified ERICVA score was determined in patients before surgical and endovascular revascularization. We included 31 patients who scored 2 or more points in the exposed group and 62 patients who scored less than 2 points in the group not exposed to amputation risk. The collected data was analyzed with the statistical program SPSS where the Relative Risk and significance was obtained with Pearson's Chi-square. The multivariate analysis was also carried out in order to obtain the adjusted relative risk. RESULTS It was identified that the simplified ERICVA score greater than or equal to 2 points was more frequent in those who underwent amputation (90.3%) compared to patients who did not undergo amputation (4.8%), increasing the risk of amputation in those patients with CLI who underwent revascularization (RR: 18.67, P<0.001). It was also possible to identify that within the group of patients that showed a high risk of amputation according to the ERICVA scale, they had a higher risk of major amputation (RR: 9.32, P<0.001) as opposed to the risk of minor amputation (RR: 1, 89, P=0.193). Among the items of the simplified ERICVA scale, the preoperative neutrophil-lymphocyte ratio and hematocrit were significantly higher in the group of amputated patients (P<0.001). In addition, it was possible to identify that the score greater than or equal to 2 was independently associated with the risk of amputation in patients revascularized with CLI (RR: 13.5, P<0.001). CONCLUSION In our patient population, the simplified ERICVA scale is useful in predicting major and minor amputation in critical limb ischemia after revascularization. The present data showed that the patients who had a simplified ERICVA score greater than or equal to 2 had a higher risk of major amputation compared to the risk of minor amputation. However, it is important to highlight that the impact on the prediction of minor amputation is greater because in some circumstances major amputation can appear as a complication of CLI.

Abstract
PURPOSE Hyperspectral imaging (HSI) and thermal imaging allow contact-free tissue perfusion measurements and may help determine the effect of endovascular treatment (EVT) in patients with peripheral arterial disease. This study aimed to detect changes in perfusion with HSI and thermal imaging peri-procedurally and determine whether these changes can identify limbs that show clinical improvement after 6 weeks. METHODS Patients with Rutherford class 2-6 scheduled for EVT were included prospectively. Hyperspectral imaging and thermal imaging were performed directly before and after EVT. Images were taken from the lateral side of the calves and plantar side of the feet. Concentrations of (de)oxyhemoglobin, oxygen saturation, and skin temperature were recorded. Angiographic results were determined on completion angiogram. Clinical improvement 6 weeks after EVT was defined as a decrease ≥ one Rutherford class. Peri-procedural changes in perfusion parameters were compared between limbs with and without good angiographic results or clinical improvement. To identify limbs with clinical improvement, receiver operating characteristic (ROC) curves were used to determine cutoff values for change in HSI. RESULTS Included were 23 patients with 29 treated limbs. Change in HSI values and temperature was not significantly different between limbs with good and poor angiographic results. Change in peri-procedural deoxyhemoglobin, determined by HSI, at the calves and feet was significantly different between limbs with and without clinical improvement at 6 week follow-up (p=0.027 and p=0.017, respectively). The ROC curve for change in deoxyhemoglobin at the calves showed a cutoff value of ≤1.0, and ≤-0.5 at the feet, which were discriminative for clinical improvement (sensitivity 77%; specificity 75% and sensitivity 62%; specificity 88%, respectively). CONCLUSIONS HSI can detect changes in perfusion at the calves after EVT in patients with Rutherford class 2-6. Peri-procedural deoxyhemoglobin changes at the calves and feet are significantly different between limbs with and without clinical improvement. Decrease in deoxyhemoglobin directly after EVT may identify limbs that show clinical improvement 6 weeks after EVT.

Abstract
OBJECTIVES To assess geriatric nutritional risk index (GNRI) in patients with chronic limb-threatening ischemia (CLTI). BACKGROUND The prevalence of CLTI continues to rise, with major amputation and mortality remaining prominent. Frailty is a vital risk factor for adverse outcomes in cardiovascular care. The GNRI is a nutrition-based surrogate for frailty that has been utilized in Southeast Asia to predict adverse events in CLTI. It has not yet been evaluated in a primarily Western population, nor in the context of wound healing. METHODS Between 8August 2017 and April 2019, we identified patients undergoing endovascular interventions for CLTI at our institution, categorized into low GNRI (≤ 94, frail) versus normal GNRI (> 94, reference). We analyzed the risks of major adverse limb events (MALE), its individual components [mortality, major amputation, and target vessel revascularization (TVR)], amputation free survival (AFS), and wound healing using Kaplan-Meier and multivariate cox-proportional hazard regression analyses. RESULTS A total of 255 patients were included in the analysis, with follow up of 14 ± 9.1 months. Lower GNRI was associated with higher cumulative event rates for MALE (71.0% vs. 43.3%, p < 0.001), mortality (34.3% vs. 15.2%, p < 0.001), major amputation (31.2% vs. 15.8%, p = 0.002), and freedom from AFS (56.0% vs. 28.2%, p < 0.001). There was a trend toward lower TVR and higher wound healing with higher GNRI score. CONCLUSIONS Our single-center, retrospective evaluation of GNRI (as a surrogate for frailty) correlated with increased risks of MALE, mortality, and major amputation. Future directions should focus not only on the recognition of these patients, but risk-factor modification to optimize long-term outcomes.

Abstract
Cell therapy is becoming an attractive alternative for the treatment of patients with no‑option critical limb ischemia (CLI). The main benefits of cell therapy are the induction of therapeutic angiogenesis and neovascularization that lead to an increase in blood flow in the ischemic limb and tissue regeneration in non‑healing cutaneous trophic lesions. In the present review, the current state of the art of strategies in the cell therapy field are summarized, focusing on intra‑operative autologous cell concentrates in diabetic patients with CLI, examining different sources of cell concentrates and their mechanisms of action. The present study underlined the detrimental effects of the diabetic condition on different sources of autologous cells used in cell therapy, and also in delaying wound healing capacity. Moreover, relevant clinical trials and critical issues arising from cell therapy trials are discussed. Finally, the new concept of cell therapy as an adjuvant therapy to increase wound healing in revascularized diabetic patients is introduced.

Abstract
OBJECTIVE Two dimensional (2D) perfusion angiography is a method that provides quantitative foot perfusion information from standard digital subtraction angiography acquisitions. The aim of this study was to test the reliability of this method in patients with chronic limb threatening ischaemia (CLTI) by investigating repeatability, and intra-observer and interobserver agreement. METHODS Twenty patients with CLTI and a below the knee endovascular revascularisation were included in a prospective clinical study. Prior to treatment two perfusion angiography runs were acquired with a five minute interval without performing an intervention. In these recordings, regions of interest were selected and time density curves and perfusion parameters were determined. To investigate intra-observer agreement one observer performed five measurements on the same acquisition for each patient. To investigate interobserver agreement three observers performed measurements on the same acquisition for each patient. Results were presented in Bland-Altman plots and as the intraclass correlation coefficient per parameter. RESULTS Two patients were excluded from repeatability analyses because of major motion artefacts. Repeatability analyses of the 18 remaining patients showed excellent correlation for every parameter (> .96). Intra-observer and interobserver agreement for all 20 patients were excellent for all parameters (1.00). CONCLUSION Repeatability and intra-observer and interobserver agreement of 2D perfusion angiography in patients with CLTI were found to be excellent. It is therefore a reliable tool when used according to the standardised methods described in this study.

Abstract
Purpose: To present the 6-month results of the Stromal Cell-Derived Factor-1 Plasmid Treatment for Patients with Peripheral Artery Disease (STOP-PAD) trial. The trial was an attempt to alter the course of chronic limb-threatening ischemia (CLTI) with a biological agent vs placebo after successful arterial revascularization at or below the knee. Materials and Methods: The multicenter, randomized, double-blinded, placebo-controlled, phase 2B STOP-PAD trial (ClinicalTrials.gov identifier NCT02544204) randomized 109 patients (mean age 71 years; 68 men) with Rutherford category 5 or 6 CLTI and evidence of persistent impaired forefoot perfusion following recent successful revascularization to 8- (n=34) or 16-mg (n=36) intramuscular injections of a non-viral DNA plasmid-based treatment vs placebo (n=34). The primary efficacy outcome was the 6-month wound healing score evaluated by an independent wound core laboratory; the primary safety endpoint was major adverse limb events (MALE), a composite of major amputation plus clinically-driven target lesion revascularization at 6 months. Results: Only one-third of the patients had complete wound healing at 6 months in the placebo (31%), 8-mg injection (33%), and 16-mg injection (33%) groups. In addition, the observed increase in the toe-brachial index from baseline to 6 months was statistically significant in each group; however, this did not result in lower rates of MALE at 6 months (24% in the placebo, 29% in the 8-mg injection, and 11% in the 16-mg injection groups). During the 6-month period, 6 patients (6%) died, and 24 patients (23%) had an amputation [only 4 (4%) major]. Conclusion: Combining revascularization and biological therapy failed to improve outcomes in CLTI at 6 months. STOP-PAD has provided insights for future trials to evaluate biological therapy.

Abstract
Peripheral vascular disease affects millions of individuals worldwide, and results in significant morbidity and mortality. The complex nature of the disease, the presence of multiple comorbidities, and the existence of a wide variety of therapeutic options suggests that a multidisciplinary approach to treatment has the potential to improve care of these patients. The success of the heart team for complex coronary artery and structural heart disease could serve as a model for the efficient and effective management of patients with peripheral vascular disease. In this paper, the authors propose a multidisciplinary vascular team approach for the treatment of critical limb ischemia, pulmonary embolism, acute ischemic stroke, and acute aortic syndromes. The successful implementation of such vascular teams has the potential to significantly enhance quality of care, improve clinical outcomes, and reduce costs. Prospective evaluation is warranted to determine how to best integrate this approach into routine clinical care.

Predictors of Major Adverse Limb Events after Open Forefoot Amputation in Patients with Chronic Limb-Threatening Ischemia. Ann Vasc Surg 2020; 66:614-620.

Abstract
BACKGROUND Management of patients with chronic limb-threatening ischemia (CLTI) and extensive foot necrosis presents a challenge for limb salvage. Our study evaluates preoperative risk factors that contributed to durability and efficacy of limb salvage after open transmetatarsal amputation (TMA) in patients with critical limb-threatening ischemia. METHODS We abstracted data from patients who underwent open TMA at Los Angeles County-University of Southern California Medical Center and Keck Hospital of University of Southern California from 2009 to 2018. Multivariable logistic regression analysis, adjusting for preoperative risk factors, was used to examine predictors of major adverse limb events (MALE). The aim was to evaluate outcomes following open TMA with MALE as the primary outcome. Our hypotheses were that outcomes would be worse for patients with foot infections and renal failure. RESULTS Forty-three open TMAs were done in 39 patients during the study period. The cohort had a mean age of 63 ± 11.6 years, 89% had a history of diabetes, 95% hypertension (HTN), 54% had end-stage renal disease (ESRD), and 26% were current smokers. MALE occurred in 39% of the cohort. Sex, race, indication, HTN, smoking status, and history of prior ipsilateral revascularization or minor amputations were not associated with MALE (P > 0.05). Multivariate logistic regression found ESRD to be an independent predictor of MALE (odds ratio 7.43, 95% confidence interval 1.12-49.17, P = 0.038) after adjusting for clinically significant covariates. CONCLUSIONS Open TMA provides acceptable rates of limb salvage for complex patients with CLTI. ESRD is an independent risk factor for MALE following open TMA in these patients. Vigilant follow-up is essential for this morbid patient population given poorer outcomes after forefoot amputation.

Abstract
PURPOSE OF REVIEW This paper provides a concise update on the management of peripheral artery disease (PAD). RECENT FINDINGS PAD continues to denote a population at high risk for mortality but represents a threat for limb loss only when associated with foot ulcers, gangrene, or infections. Performing either angiogram or non-invasive testing for all patients with foot ulcers, gangrene, or foot infections will help increase the detection of PAD, and refined revascularization strategies may help optimize wound healing in this patient group. Structured exercise programs are becoming available to more patients with claudication as methods to improve adherence to community-based exercise programs will improve. Finally, ensuring more patients with PAD receive aspirin therapy and statins may improve long-term survival, while further research will help determine if adding newer antiplatelet or anticoagulant medications may reduce leg amputations in selected patients. Clinicians should have a low threshold to obtain an angiogram and to pursue revascularization in patients with foot ulcers, gangrene, or foot infections. In patients with claudication, clinicians should maximize the benefits derived from exercise therapy and medical management before offering percutaneous or surgical revascularization.

Abstract
The healing of venous and arterial ulcers is slow, and in some cases, they may not heal at all. This study aims to demonstrate the clinical advantage of Nevelia®, an innovative collagen dermal template substitute (DS) in venous and arterial chronic ulcers treatment. 35 patients affected by chronic vascular ulcers with a mean area of 35.1 ± 31.8 cm2 were treated with DS followed by autologous dermal epidermal graft (DEG). Follow-up was performed at 7-14-21 and 28 days after DS implant and 7-14-21 and 28 days after DEG. At 28 days after DEG, the mean values of Manchester Scar Scale was of 1.8 ± 0.7 for skin color, 1.6 ± 0.7 for skin contour, 1.7 ± 0.7 for distortion, and 1.7 ± 0.7 for skin texture, whereas skin was matte in 27 patients (77%) and shiny in the remaining eight cases (23%). Histological findings correlate with the clinical result showing a regenerated skin with reactive epidermal hyperplasia and dermal granulation tissue after two weeks (T1), and after three weeks (T2) a re-epithelialization and a formed new tissue architecture analogue to normal skin physiology. These data suggest that Nevelia® could be useful to treat chronic venous and arterial ulcers.

Abstract
The efficacy of biologic therapies in critical limb ischemia (CLI) remains elusive, in part, due to limitations in trial design and patient selection. Using a novel design, we examined the impact of complementing revascularization therapy with intramuscular JVS-100 – a non-viral gene therapy that activates endogenous regenerative repair pathways. In this double-blind, placebo-controlled, Phase 2B trial, we randomized 109 patients with CLI (Rutherford class V or VI) to 8 mg or 16 mg intramuscular injections of placebo versus JVS-100. Patients were eligible if they persistently had reduced forefoot perfusion, by toe–brachial index (TBI) or skin perfusion pressure (SPP), following successful revascularization with angiographic demonstration of tibial arterial flow to the ankle. The primary efficacy end point was a 3-month wound healing score assessed by an independent wound core laboratory. The primary safety end point was major adverse limb events (MALE). Patients’ mean age was 71 years, 33% were women, 79% had diabetes, and 8% had end-stage renal disease. TBI after revascularization was 0.26, 0.27, and 0.26 among the three groups (placebo, 8 mg, and 16 mg injections, respectively). Only 26% of wounds completely healed at 3 months, without any differences between the three groups (26.5%, 26.5%, and 25%, respectively). Similarly, there were no significant changes in TBI at 3 months. Three (2.8%) patients died and two (1.8%) had major amputations. Rates of MALE at 3 months were 8.8%, 20%, and 8.3%, respectively. While safe, JVS-100 failed to improve wound healing or hemodynamic measures at 3 months. Only one-quarter of CLI wounds healed at 3 months despite successful revascularization, highlighting the need for additional research in therapies that can improve microcirculation in these patients.

Abstract
BACKGROUND To evaluate outcomes after lower extremity revascularization for critical limb ischemia with tissue loss in patients with chronic immune-mediated inflammatory disease. METHODS A retrospective medical record review of all lower extremity revascularization for critical limb ischemia with tissue loss at a university-affiliated hospital over a 3-year period was completed for demographics, comorbidities, lower extremity revascularization indication, angiogram results, complications, mortality, limb salvage, and reintervention. Chronic immune-mediated inflammatory disease (CIID) and control (no autoimmune disease) were compared by chi-squared test, Student's t-test, Kaplan-Meier, and Cox Regression. RESULTS There were 349 procedures performed (297 patients): (1) 44 (13%) primary amputations and (2) 305 (87%) lower extremity revascularizations, in which 83% were endovascular interventions; 12% was bypass; and 5% was hybrid, in which 40% was infrainguinal and 60% was infrageniculate, 72% Wounds Ischemia Infection Score System (WIFi) tissue loss class 2-3, 35% CIID. No differences were noted between CIID and control for primary amputation (P = 0.11), lower extremity revascularization type (P = 0.50), or lower extremity revascularization anatomic level (P = 0.43). Mean age was 71 + 13 years, and 56% of the patients were of male gender. Those with CIID were of similar age as controls (71 ± 14 vs. 71 ± 13; P = 0.87) and presented with comparable runoff: (1) ≤1 vessel (52% vs. 47%; P = 0.67), (2) WIFi tissue loss classification class 2-3 (66% vs. 76%; P = 0.09), and (3) WIFi infection classification class 2-3 (29% vs. 30%; P = 0.9). They were also less likely to be male (47% vs. 61%; P = 0.022) or current smokers (13% vs. 27%; P = 0.008). Postoperative mortality (P = 0.70) morbidity and reoperation (0.31) were comparable. Twenty-four-month survival was similar for CIID and control (83% ± 5% vs. 86% + 3%; P = 0.78), as was the amputation-free interval (69% ± 5% vs. 61% ± 4%; P = 0.18) and need for target extremity revascularization (40% vs. 53%; P = 0.04). Use of steroids and other anti-inflammatory medications was associated with improved 24-month amputation-free interval (87% ± 9% vs. 63% ± 3%; P = 0. 05). Dialysis (odds ratio: 2.6; 1.5-4.7; P = 0.001), WIFi infection class 2-3 (odds ratio: 2.8; 1.6-4.9; P < 0.001), prerunoff vessel (0-1 vs. 2-3) to the foot (odds ratio: 0.52; 0.37-0.73; P < 0.001), steroids/other anti-inflammatory agents (0.29; 0.06-0.96; P = 0.04), and statins (0.44; 0.25-0.77; P = 0.005) were independent predictors of 24-month amputation-free interval (Cox proportional hazard ratio). CONCLUSIONS Patients with critical limb ischemia, tissue loss, and concomitant CIID can be successfully treated with lower extremity revascularization with similar limb salvage and need for reintervention. Steroid/anti-inflammatory use appears beneficial.

Abstract
The method of suturing for incisions is crucial for the comprehensive treatment of clinical patients with breast cancer. Suturing is considered a major part of post-surgical recovery and may serve as a marker for evaluation of surgical outcome. The present study aimed to establish an effective means of suturing for patients who received modified radical surgery that helps to improve the cosmetic outcome of the incision. Enrolled patients were divided into an active and a control group. Ti-Ni memory alloy wire for intradermal suture in the active group and silk for interruption suture in the control group were applied to assess the different prognosis-associated factors. The Vancouver Scar Scale (VSS) was used to evaluate the wound size and the recovery time of the scars. The association between diabetes and the number of days of wound healing was also analyzed. The results indicated that the mean VSS score of the active group was decreased compared with that of the control group (P<0.001). The VSS scores of four main features (vascularity, pigmentation, pliability and height) between the two groups also statistically differed (P<0.001). Furthermore, the mean number of days of wound healing was significantly decreased for the active group compared with that for the control group (P=0.0026) in the patients with diabetes. In addition, the usage of Ti-Ni memory alloy wire was able to decrease the mean number of wound healing days between patients with diabetes and their non-diabetic counterparts (P=0.7009). The present study indicated that intradermal suture offers improved cosmetic outcome for patients undergoing mastectomy with or without axillary surgery. This technique may be useful for preventing scar overgrowth and for facilitating the recovery process in patients with diabetes.

Abstract
OBJECTIVES This study sought to determine the relationship between change in ankle-brachial index (ABI) and toe-brachial index (TBI) and outcomes following revascularization of critical limb ischemia (CLI). BACKGROUND An increase in ABI of 0.15 after revascularization for peripheral artery disease with claudication is considered significant. However, the utility of using change in ABI or TBI to predict outcomes in patients with CLI is unproven. METHODS This was an observational study of 218 patients with Rutherford class V or VI CLI that underwent endovascular therapy. Receiver-operating characteristic curve analysis determined cutpoints in post-procedure ABI and TBI, as well as change in these values for endpoints of wound healing, major adverse limb events (MALE), and repeat revascularization. RESULTS After multivariable Cox proportional hazards analysis adjusting for age, diabetes, glomerular filtration rate, smoking, Rutherford class, and baseline ABI or TBI, neither static post-procedure ABI nor post-procedure TBI were associated with wound healing (hazard ratio [HR]: 1.21; 95% confidence interval [CI]: 0.77 to 1.89; p = 0.40; HR: 1.49; 95% CI: 0.98 to 2.27; p = 0.065, respectively). However, change in ABI ≥0.23 was independently associated with wound healing (HR: 1.87; 95% CI: 1.12 to 3.15; p = 0.018) and less repeat revascularization (HR: 0.40; 95% CI: 0.19 to 0.84; p = 0.015), but not MALE. Increase in TBI ≥0.21 was independently associated with wound healing (HR: 1.63; 95% CI: 1.02 to 2.59; p = 0.039), and reduced MALE (HR: 0.27; 95% CI: 0.09 to 0.77; p = 0.014), but not repeat revascularization. CONCLUSIONS A change in ABI and TBI from pre-procedural values provides prognostic value in determining which patients may have wound healing and reduced MALE.

Clinical Outcomes of Pedal Artery Angioplasty for Patients With Ischemic Wounds: Results From the Multicenter RENDEZVOUS Registry. JACC Cardiovasc Interv 2017; 10:79-90. [PMID: 28057289 DOI: 10.1016/j.jcin.2016.10.025] [Citation(s) in RCA: 69] [Impact Index Per Article: 9.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2016] [Revised: 10/03/2016] [Accepted: 10/20/2016] [Indexed: 11/29/2022]
Abstract
OBJECTIVES The aim of this study was to investigate the clinical outcomes of pedal artery angioplasty (PAA) for patients with critical limb ischemia. BACKGROUND Pedal artery disease is considered a predictor of delayed wound healing (DH) after endovascular therapy. Adjunctive PAA might improve the speed and extent of wound healing. METHODS Consecutive patients with critical limb ischemia (n = 257) presenting with de novo infrapopliteal and pedal artery disease were retrospectively reviewed from a multicenter registry. Patients were divided into 2 groups according to whether PAA was performed (n = 140) or not (n = 117). The rate of wound healing and time to wound healing were compared between these groups. DH score was calculated using the number of independent predictors of DH. Patients were stratified into 3 groups according to DH score: low risk (DH score = 0), moderate risk (DH score = 1 or 2), and high risk (DH score = 3). Estimated efficacy was analyzed for each risk-stratified population. RESULTS The rate of wound healing was significantly higher (57.5% vs. 37.3%, p = 0.003) and time to wound healing significantly shorter (211 days vs. 365 days; p = 0.008) in the PAA group. In a multivariate analysis, nonambulatory status, target wound depth (UT grade ≥2), and daily hemodialysis were revealed as predictors of DH. In the moderate-risk population, adjunctive PAA significantly improved the rate of wound healing (59.3% vs. 33.9%; p = 0.001). In the high-risk population, however, PAA did not affect wound healing. CONCLUSIONS Patients who underwent PAA showed a higher rate of wound healing and shorter time to wound healing, especially in the moderate-risk population. With regard to wound healing, this aggressive strategy might become a salvage procedure for patients with critical limb ischemia presenting with pedal artery disease.

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.

[PMID: 28376797 PMCID: PMC5379505 DOI: 10.1186/s12933-017-0524-8] [Citation(s) in RCA: 44] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2017] [Accepted: 03/25/2017] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND Patients with diabetes concomitant to critical limb ischemia (CLI) represent a sub-group at particular risk. Objective of this analysis is to evaluate the actual impact of diabetes on treatment, outcome, and costs in a real-world scenario in Germany. METHODS We obtained routine-data on 15,332 patients with CLI with tissue loss from the largest German health insurance, BARMER GEK from 2009 to 2011, including a follow-up until 2013. Patient data were analyzed regarding co-diagnosis with diabetes with respect to risk profiles, treatment strategy, in-hospital and long-term outcome including costs. RESULTS Diabetic patients received less overall revascularizations in Rutherford grades 5 and 6 (Rutherford grade 5: 45.0 vs. 55.5%; Rutherford grade 6: 46.5 vs. 51.8; p < 0.001) and less vascular surgery (Rutherford grade 5: 13.4 vs. 23.4; Rutherford grade 6: 19.7 vs. 29.6; p < 0.001), however more often endovascular revascularization in Rutherford grade 6 (31.0 vs. 28.1; p = 0.004) compared to non-diabetic patients. Diabetes was associated with a higher observed ratio of infections (35.3 vs. 23.5% Rutherford grade 5; 44.3 vs. 27.4% Rutherford grade 6; p < 0.001) and in-hospital amputations (13.0 vs. 7.3% Rutherford grade 5; 47.5 vs. 36.7% Ruth6; p < 0.001). Diabetes further increased the risk for amputation during follow-up [Rutherford grade 5: HR 1.51 (1.38-1.67); Rutherford grade 6: HR 1.33 (1.25-1.41); p < 0.001], but not for death. CONCLUSIONS Diabetes increases markedly the risk of amputation attended by higher costs in CLI patients with tissue loss (OR 1.67 at Rutherford 5, OR 1.53 at Rutherford 6; p < 0.001), but is associated with lower revascularizations. However, in Rutherford grades 5 and 6, concomitant diabetes does not further worsen the overall poor survival.

Abstract
Critical limb ischemia (CLI), the most advanced form of peripheral artery disease, is associated with significant morbidity, mortality, and health care resource utilization. It is also associated with physical, as well as psychosocial, consequences such as amputation and depression. Importantly, after a major amputation, patients are at heightened risk of amputation on the contralateral leg. However, despite the technological advances to manage CLI with minimally invasive technologies, this condition often remains untreated, with significant disparities in revascularization and amputation rates according to race, socioeconomic status, and geographic region. Care remains disparate across medical specialties in this rapidly evolving field. Many challenges persist, including appropriate reimbursement for treating complex patients with difficult anatomy. This paper provides a comprehensive summary that includes diagnostic assessment and analysis, endovascular versus open surgical treatment, regenerative and adjunctive therapies, and other important aspects of CLI.
