Abstract
BACKGROUND Elevated lipoprotein(a) [Lp(a)] levels are a causal risk factor for peripheral artery disease. However, data on their effect on delayed wound healing in patients with chronic limb-threatening ischemia (CLTI) are limited. The present study assessed the association between elevated Lp(a) levels and delayed wound healing in patients with CLTI. METHODS AND RESULTS This study included 280 patients who successfully received endovascular therapy for CLTI between September 2016 and August 2021. High Lp(a) levels were defined as those >30 mg/dL. The primary outcome was wound healing. During a median follow-up of 20.4 months (interquartile range 6.8-38.6 months), 146 patients achieved wound healing. The wound healing rate at 24 months was significantly lower in the high Lp(a) than low Lp(a) group (41.1% vs. 86.3%, respectively; P<0.001). The adjusted risk ratio was 0.19 (95% confidence interval 0.13-0.29, P<0.001). Lp(a) levels of 31-50 and >50 mg/dL, but not 16-30 mg/dL, were significantly associated with delayed wound healing relative to Lp(a) levels of ≤15 mg/dL. CONCLUSIONS Elevated Lp(a) levels were independently associated with delayed wound healing in patients with CLTI treated with endovascular therapy.

Abstract
BACKGROUND For chronic limb-threatening ischemia, revascularization has been reported for occlusions but not for stenosis in the inframalleolar (IM) lesions. We investigated the clinical outcomes of balloon dilation for stenotic IM lesions distal to the treatment target in the infrapopliteal (IP) legion. METHODS We conducted a retrospective analysis of patients who had chronic limb-threatening ischemia and underwent revascularization of stenotic IM lesions distal to the target IP lesions between January 2015 and August 2022. The outcome measures were amputation-free survival, wound healing rate, and freedom from target IM reintervention. RESULTS The 87 patients had a mean age of 72.7 ± 10.7 years and comprised 67.8% men, 74.7% with diabetes mellitus, 55.2% on dialysis, 33.3% who had Rutherford six classification. The amputation-free survival (AFS), wound healing, and freedom from target IM reintervention rates at 1 year were 82.9%, 53.3%, and 58.4%, respectively. On Cox proportional multivariate analysis, the predictors were Wound, Ischemia, and foot Infection (WIfI) ≥3 and diffuse stenosis in the target IM vessels for delayed wound healing and Global Limb Anatomic Staging System stage Ⅲ and ≥3 diseased IM vessels before endovascular therapy for target IM reintervention. At the time of reintervention, the lesion morphology had progressed from stenosis to occlusion in 50% of cases. CONCLUSIONS In patients with chronic limb-threatening ischemia, revascularization of stenosis in IM lesions showed a high reintervention rate and progression of lesion morphology, although AFS and wound-healing rates were acceptable.

Abstract
BACKGROUND Endovascular therapy (EVT) with devices such as drug-coated balloons (DCBs) and drug-eluting stents (DESs) for atherosclerotic disease in the femoropopliteal (FP) artery has been established. However, EVT using drug-based devices for chronic limb-threatening ischemia (CLTI) remains challenging. The optimal device for FP lesions in patients with CLTI remains unknown. This study compared the clinical efficacy of DCB and DES in patients with CLTI and FP lesions. METHODS AND RESULTS This retrospective single-center study included 539 consecutive patients (562 lesions) treated with EVT between January 2018 and December 2022; 166 patients with CLTI and Rutherford Class 5 or 6 wounds underwent EVT with DCB or DES. Clinical outcomes were compared between 53 pairs after propensity score matching. There were no significant differences between the DCB and DES groups in the incidence of complete wound healing without death or major amputation (84.8% vs. 80.2%, respectively; P=0.99), primary patency (69.4% vs. 75.6%, respectively; P=0.65), and freedom from target lesion revascularization at 1 year (78.6% vs. 78.0%, respectively; P=0.92). Multivariate analysis showed that complete wound healing at 1 year is negatively associated with hemodialysis and Wound, Ischemia, and foot Infection Stage 4, but positively associated with Global Limb Anatomic Staging System FP Grade 3 or 4. CONCLUSIONS No significant differences in clinical outcomes were found between DCB and DES for patients with CLTI and FP lesions.

Abstract
Endovascular treatment (EVT) for peripheral artery disease in patients with chronic limb-threatening ischemia (CLTI) is a common practice in contemporary medicine and its effectiveness is widely acknowledged. However, refractory ulcers can occasionally be encountered, particularly in patients who underwent renal transplantation (RT), even after successful EVT. To date, there have been no data on prognosis reported following EVT for CLTI in RT recipients. We included all RT recipients who underwent EVT in our hospital between 2010 and 2022. We analyzed data from 43 limbs with ischemic ulcerations classified as Rutherford class 5 or 6, which were managed solely with EVT (i.e., no bypass surgery was performed). The primary and secondary outcomes of our study were the incidence of complete wound healing and major adverse limb events (MALE), including clinically driven target vessel revascularization, major amputation, and all-cause death. The median follow-up was 31 months. The mean age of the study population was 64.7 ± 8.7 years, with predominantly male participants (79.1%). The overall wound healing rate was 34.9%. Kaplan-Meier curve revealed that wound healing rates at 1 and 3 years were 33.6% and 40.9%, respectively. The wound healing rates of RT recipients who underwent EVT for CLTI were found to be less than satisfactory.

Abstract
OBJECTIVE There is no established consensus or guidelines for wound management after revascularization for patients with chronic limb-threatening ischemia (CLTI) without severe infection. This study is designed to evaluate the clinical effect of the wound management strategy on toe wounds after revascularization for CLTI. METHODS This retrospective cohort study was performed at eight institutions affiliated with Keio University School of Medicine in Japan and included 261 patients who underwent revascularization for CLTI between April 2019 and July 2021. We identified 132 patients with toe wounds from the database who had restored in-line blood flow to the foot. Patients were divided into two groups by the timing of toe resection after revascularization, which dictated the wound management policy. Group A (62 patients) underwent early toe amputation for suspected osteomyelitis, whereas group B (70 patients) underwent watchful waiting. The primary outcome was wound healing after revascularization; the secondary outcome was major amputation. We compared outcomes between groups A and B after propensity score matching. RESULTS Using propensity score matching, each patient in group A (33 patients) was matched with a patient in group B (33 patients). Wound healing in matched group A was significantly better than that in matched group B (respectively: 1-year wound healing rate: 90.0% vs 68.2%, P < .001; median wound healing time: 65 days vs 258 days, P < .01). Although five major amputations were necessary in matched group B, none were required in matched group A (P = .05). The high rate of major amputations in group B was attributed to the sudden exacerbation of infection. Limb salvage rate in matched group A exceeded matched group B (100.0% vs 90.5%: 1-year limb salvage rate, P = .02). CONCLUSIONS Early toe amputation for highly suspected osteomyelitis in patients with CLTI with toe wounds may expedite wound healing compared with watchful waiting, potentially avoiding unnecessary major amputation. Considering the wound management strategy is crucial when evaluating wound healing outcomes in patients with CLTI with revascularization.

Abstract
Introduction. Diabetes is a chronic disease characterized by a high blood glucose level. It can lead to complications that affect the quality of life and increase the costs of healthcare. In recent years, prevalence and mortality rates have increased worldwide. The development of models with high predictive performance can help in the early identification of the disease. Objective. To develope a model based on artificial intelligence to support clinical decisionmaking in the early detection of diabetes. Materials and methods. We conducted a cross-sectional study, using a dataset that contained age, signs, and symptoms of patients with diabetes and of healthy individuals. Pre-processing techniques were applied to the data. Subsequently, we built the model based on fuzzy cognitive maps. Performance was evaluated with three metrics: accuracy, specificity, and sensitivity. Results. The developed model obtained an excellent predictive performance with an accuracy of 95%. In addition, it allowed to identify the behavior of the variables involved using simulated iterations, which provided valuable information about the dynamics of the risk factors associated with diabetes. Conclusions. Fuzzy cognitive maps demonstrated a high value for the early identification of the disease and in clinical decision-making. The results suggest the potential of these approaches in clinical applications related to diabetes and support their usefulness in medical practice to improve patient outcomes.

Abstract
This study investigated the effect of early rehabilitation on gait restoration, wound healing, and home discharge in patients with lower extremity (LE) chronic wounds. This multicenter, retrospective cohort study included 233 Japanese inpatients who received treatment for LE chronic wounds from April 2012 to March 2015. A multivariate analysis was conducted using outcomes of gait restoration, wound healing, and home discharge as dependent variables. Other survey items were used as independent variables. Early rehabilitation was extracted as an independent factor with gait restoration (hazard ratio [HR] 1.82, P < .01) and home discharge (HR 1.77, P < .001) as dependent factors by the stepwise method in Cox proportional-hazards regression analysis, but it was not extracted as an independent factor with wound healing as the dependent factor by the stepwise method as well as the forced entry method (P = .44). A significant relationship between the presence of gait restoration and home discharge was observed in the chi-square test (P<.001), and the duration from admission to gait restoration was significantly correlated to the duration from admission to home discharge (Pearson's product-moment correlation coefficient; r=.89, P<.0001). Early rehabilitation was a positive factor for gait restoration and home discharge in chronic LE wound patients.

Abstract
INTRODUCTION Lipoprotein apheresis (LA) is a possible adjunct treatment for no-option chronic limb-threatening ischemia (CLTI). This study aimed to assess the impact of a novel LA for no-option CLTI. METHODS We retrospectively assessed 19 patients with no-option CLTI treated using the novel LA. The primary outcome was a change in the skin perfusion pressure (SPP) after treatment with LA, and the secondary outcomes were changes in the viscosity-related laboratory parameters. RESULTS The wound-healing rate was 68.4%. The SPP at 2-3 weeks after series of LA were significantly higher both in the dorsal (41 vs. 53 mmHg, p = 0.037) and plantar (50.0 vs. 61.0 mmHg, p = 0.018) sides, compared to those at baseline. The viscosity-related laboratory markers were also significantly improved after the treatment; low-density lipoprotein-cholesterol (57.0 vs. 43.0 mg/dL, p = 0.002), fibrinogen (333 vs. 258 mg/dL, p < 0.001), and C-reactive protein (0.99 vs. 0.42 mg/dL, p = 0.001). CONCLUSION The novel LA significantly increased the SPP and improved relevant laboratory findings.

Revascularisation of Chronic Limb Threatening Ischaemia in Patients with no Pedal Arteries Leads to Lower Midterm Limb Salvage. Eur J Vasc Endovasc Surg 2023; 65:878-886.

Abstract
OBJECTIVE Chronic limb threatening ischaemia (CLTI) involving the infragenicular arteries is treated by distal angioplasty or pedal bypass; however, this is not always possible, due to chronically occluded pedal arteries (no patent pedal artery, N-PPA). This pattern represents a hurdle to successful revascularisation, which must be limited to the proximal arteries. The aim of the study was to analyse the outcome of patients with CLTI and N-PPA after a proximal revascularisation. METHODS All patients with CLTI submitted to revascularisation in a single centre (2019 - 2020) were analysed. All angiograms were reviewed to identify N-PPA, defined as total obstruction of all pedal arteries. Revascularisation was performed with proximal surgical, endovascular, and hybrid procedures. Early and midterm survival, wound healing, limb salvage, and patency rates were compared between N-PPA and patients with one or more patent pedal artery (PPA). RESULTS Two hundred and eighteen procedures were performed. One hundred and forty of 218 (64.2%) patients were male, mean age 73.2 ± 10.6 years. The procedure was surgical in 64/218 (29.4%) cases, endovascular in 138/218 (63.3%), and hybrid in 16/218 (7.3%). N-PPA was present in 60/218 (27.5%) cases. Eleven of 60 (18.3%) cases were treated surgically, 43/60 (71.7%) by endovascular and 6/60 (10%) by hybrid procedures. Technical success was similar in the two groups (N-PPA 85% vs. PPA 82.3%, p = .42). At a mean follow up of 24.5 ± 10.2 months, survival (N-PPA 93.7 ± 3.5% vs. PPA 95.3 ± 2.1%, p = .22) and primary patency (N-PPA 53.1 ± 8.1% vs. PPA 55.2 ± 5%, p = .56) were similar. Limb salvage was significantly lower in N-PPA patients (N-PPA 71.4 ± 6.6% vs. PPA 81.5 ± 3.4%, p = .042); N-PPA was an independent predictor of major amputation (hazard ratio [HR] 2.02, 1.07 - 3.82, p = .038) together with age > 73 years (HR 2.32, 1.17 - 4.57, p = .012) and haemodialysis (2.84, 1.48 - 5.43, p = .002). CONCLUSION N-PPA is not uncommon in patients with CLTI. This condition does not hamper technical success, primary patency, and midterm survival; however, midterm limb salvage is significantly lower than in patients with PPA. This should be considered in the decision making process.

Abstract
OBJECTIVES To assess wound healing after simultaneous endovascular treatment (EVT) and minor forefoot amputation and identify the predictors of delayed wound healing in patients with chronic limb-threatening ischemia (CLTI) and bacterial infections of the wounds. METHODS In this single-center retrospective cohort study, we evaluated 79 consecutive limbs with tissue loss from 73 CLTI patients who underwent simultaneous EVT and minor forefoot amputation between November 2017 and May 2020. To estimate the rate of wound healing after the simultaneous procedure, we used the Kaplan-Meier method. To assess the association between baseline characteristics and delayed wound healing, we used the Cox proportional hazard model. RESULTS All patients who underwent the simultaneous procedure had ischemic wounds with bacterial infection. The rate of wound healing at 6 months reached 82%. The median time for wound healing was 76 days. According to multivariable analysis, Lisfranc/Chopart amputation (hazard ratio (HR) 2.46, 95% confidence interval (CI) 1.09-6.60), absence of above-the-knee (ATK) occlusive lesions (HR 1.89, 95% CI 1.04-3.45), and poor below-the-ankle (BTA) runoff (HR 1.77, 95% CI 1.01-3.11) were independent predictors of delayed wound healing. CONCLUSION Lisfranc/Chopart amputation, absence of ATK occlusive lesions, and poor BTA runoff were independent predictors of delayed wound healing after simultaneous EVT and minor forefoot amputation in patients with CLTI and bacterial infections of the wound.

[PMID: 35650020 PMCID: PMC9981346 DOI: 10.5551/jat.63593] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 04/21/2022] [Indexed: 12/27/2022] Open
Abstract
AIM This study aimed to report injury precipitating tissue loss and to provide updated information on the time from tissue loss occurrence to referral to a vascular center for patients who developed chronic limb-threatening ischemia (CLTI) in Japan. METHODS We examined 450 patients who developed CLTI with tissue loss and were registered in a multicenter prospective study between October 2017 and June 2020. They were referred to the participating vascular centers for revascularization. Information on the injury precipitating tissue loss and time to referral was collected at registration. The severity of tissue loss was evaluated using the Wound, Ischemia, and foot Infection classification. RESULTS Injury precipitating tissue loss was absent in 52.0% (95% confidence interval, 47.3%-56.6%) of the patients. The absence was associated with lower albumin levels and preserved pressure sensation. Although the time to referral was significantly shorter in cases without a history of prereferral revascularization, 16.8% (12.8%-20.7%) of the patients were referred to the vascular centers more than 3 months after tissue loss occurrence. Time to referral, but not the lack of a clear precipitant for tissue loss, was significantly associated with the severity of tissue loss. CONCLUSION A clear precipitant for tissue loss was often lacking, particularly in patients with low albumin levels and preserved pressure sensation. Delayed referral to a vascular center is still common.

High Global Limb Anatomic Staging System Femoropopliteal Grade is Positively Associated with Wound Healing in Patients with Chronic Limb-Threatening Ischemia Undergoing Endovascular Therapy Only for Femoropopliteal Disease. Ann Vasc Surg 2023; 92:264-271. [PMID: 36634898 DOI: 10.1016/j.avsg.2022.11.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 11/22/2022] [Accepted: 11/29/2022] [Indexed: 01/11/2023]
Abstract
BACKGROUND To investigate the prognostic impact of femoropopliteal (FP) arterial anatomic severity including classification by the global limb anatomic staging system (GLASS) on wound healing in patients with chronic limb-threatening ischemia (CLTI) who had undergone endovascular therapy (EVT) only for FP lesions. METHODS This was a retrospective single-center study. We treated 349 consecutive de novo CLTI limbs with tissue loss from January 2017 to May 2021. Among these, 91 limbs treated via EVT only for FP lesions were enrolled. We compared the clinical background, infrapopliteal (IP)/FP arterial anatomical characteristics, and EVT results between the limbs with GLASS FP grade 1 or 2 (low GLASS FP, n = 20) and those with GLASS FP grade 3 or 4 (high GLASS FP, n = 71). The Kaplan-Meier method was used to estimate the wound healing rate. The Cox proportional hazard model was used to assess the association between baseline characteristics and wound healing. RESULTS No patient underwent EVT for IP lesions. IP arterial anatomical characteristics did not show any significant difference between the low and high GLASS FP groups. The cumulative wound healing rate after EVT was significantly higher in the high GLASS FP group than in the low GLASS FP group (88% vs. 39% at 6 months; P < 0.001). Multivariate analysis revealed that low wound, ischemia, and foot infection (WIfI) clinical stage (stage 1 or 2) (hazard ratio [HR] 2.33; 95% confidence interval [CI] 1.32-4.17) and high GLASS FP (grade 3 or 4) (HR 5.18; 95% CI 1.99-13.51) were independent factors for wound healing. CONCLUSIONS High GLASS FP grade was positively associated with wound healing after EVT only for FP lesions.

Limb outcomes based on limb severity and anatomic complexity following infrapopliteal vein bypass for Japanese patients with chronic limb-threatening ischemia. J Vasc Surg 2023; 77:1468-1476.e3. [PMID: 36608743 DOI: 10.1016/j.jvs.2022.12.060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 12/24/2022] [Accepted: 12/28/2022] [Indexed: 01/05/2023]
Abstract
OBJECTIVE The 2019 Global Vascular Guidelines recommend a suitable initial revascularization method with reference to limb severity (wound, ischemia, and foot infection [WIfI] stage) and anatomic complexity (Global Limb Anatomical Staging System [GLASS] stage). However, limb outcomes after revascularization among WIfI and GLASS stages have not been investigated fully after infrapopliteal vein bypass. The purpose of this study was to assess the four Global Vascular Guideline-recommended limb outcomes after infrapopliteal vein bypass in cases with different WIfI and GLASS stages. METHODS Patients who underwent infrapopliteal vein bypass for chronic limb-threatening ischemia at a single center were analyzed retrospectively. Medium-term limb outcomes were compared among WIfI and GLASS stages. The primary end points were limb salvage rate and major to minor amputation ratio, and the secondary end points were wound healing rate and wound healing time. RESULTS A total of 353 infrapopliteal vein bypasses were performed in 284 patients with tissue loss (male, 193 patients; median age, 77 years; diabetes, 71%; hemodialysis, 41%). A total of 111 limbs (31%) required only minor amputation and 38 limbs (11%) required major amputation. The major to minor amputation ratio was 0.34 with no significant differences among WIfI stages or GLASS stages. The 3-year limb salvage rate was 87%. This rate was significantly lower in WIfI stage 4 than in stage 2 (P = .049), but did not differ significantly among GLASS stages. The 12-month wound healing rate was 86%. This rate was also significantly lower in WIfI stage 4 than in stages 2 and 3 (both P < .001), but did not differ significantly among GLASS stages. The median wound healing time was 55 days (range, 32-110 days), and was significantly longer in WIfI stage 4 compared with stages 2 (P = .001) and 3 (P < .001), but showed no significant differences among GLASS stages. CONCLUSIONS The limb salvage rate, wound healing rate, and wound healing time were associated with limb severity (WIfI stage), but not with anatomic complexity (GLASS stage). These findings suggest that an appropriate preoperative strategy and careful perioperative management are important for patients with greater limb severity.

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
ObjectivesTo evaluate foot blood volume and hemodynamics and explore whether quantitative techniques can guide revascularization.Materials and methodsA prospective single-center cohort study included thirty-three patients with infrapopliteal artery occlusion who underwent percutaneous transluminal angioplasty (PTA) between November 2016 and May 2020. The time-to-peak (TTP) from color-coded quantitative digital subtraction angiography (CCQ-DSA) and parenchymal blood volume (PBV) were used to evaluate the blood volume and hemodynamic changes in different regions of the foot before and after the operation.ResultsAfter the intervention procedure, the overall blood volume significantly increased from 25.15 ± 21.1 ml/1,000 ml to 72.33 ± 29.3 ml/1,000 ml (p < 0.001, with an average increase of 47.18 ml/1,000 ml. The overall TTP decrease rate, postoperative blood flow time significantly faster than those preoperatively, from 22.93 ± 7.83 to 14.85 ± 5.9 s (p < 0.001, with an average decrease of 8.08 s). Direct revascularization (DR) resulted in significant blood volume improvement than compared with indirect revascularization (IR) [188% (28, 320) vs.51% (10, 110), p = 0.029]. Patients with DR had a significantly faster blood flow time than those with IR [80% (12, 180) vs. 26% (5, 80), p = 0.032]. The ankle-brachial index (ABI) of the affected extremity also showed an significant change from 0.49 ± 0.3 to 0.63 ± 0.24 (p < 0.001) after the intervention. The relative values of ΔTTP and ΔABI showed a weak correlation (r = −0.330).ConclusionsThe quantitative measurement results based on PBV and CCQ-DSA techniques showed that the overall blood volume increased significantly and that the foot distal hemodynamics were significantly improved after endovascular treatment. DR in the ischemic area could r improve foot perfusion.

Abstract
BACKGROUND Percutaneous transluminal angioplasty (PTA) is widely used as a first-line revascularisation option in patients with chronic limb threatening ischemia (CLTI). This study aimed to evaluate the short-term endovascular revascularisation treatment outcomes of a cohort of Rutherford 6 (R6) CLTI patients, from a multi-ethnic Asian population in Singapore. Patients with R6 CLTI who underwent endovascular revascularisation from June 2019 to February 2020 at Singapore General Hospital, a tertiary vascular centre in Singapore, were included and followed up for one year. Primary outcome measures included number and type of reinterventions required, 3-, 6- and 12-month mortality, 6- and 12-month amputation free survival (AFS), wound healing success and changes in Rutherford staging after 3, 6 and 12 months. RESULTS Two hundred fifty-five procedures were performed on 86 patients, of whom 78 (90.7%) were diabetics, 54 (62.8%) had coronary artery disease (CAD) and 54 (62.8%) had chronic kidney disease (CKD). 42 patients (48.8%) required reintervention within 6 months. Multivariate analysis revealed that the presence of CAD was a significant independent predictor for reintervention. Mortality was 15.1%, 20.9% and 33.7% at 3, 6 and 12 months respectively. AFS was 64.0% and 49.4% at 6 and 12 months. Inability to ambulate, congestive heart failure (CHF), dysrhythmia and CKD were significant independent predictors of lower 12-month AFS. CONCLUSIONS PTA for R6 CLTI patients was associated with relatively high mortality and reintervention rates at one year. CAD was an independent predictor of reintervention. More research is required to help risk stratify which CLTI patients would benefit from an endovascular-first approach versus conservative treatment or an immediate major lower extremity amputation policy.

Abstract
Objective: In this study, we aim to evaluate the efficacy of early closed toe amputation on the wound management of toe ulcers with suspected osteomyelitis after revascularization for chronic limb-threatening ischemia (CLTI). Methods: This retrospective study included patients who have underwent revascularization for toe ulcers associated with CLTI at Shizuoka Red Cross Hospital from 2015 to 2021. Wound management comprised early closed toe amputation for toe ulcers with suspected osteomyelitis (19 toes in 17 patients) or conservative treatment (35 toes in 26 patients). The primary endpoint was wound healing after revascularization. We compared the wound healing rate at 90 days and median healing time of early closed toe amputation versus conservative treatment. Results: Compared with the conservative treatment, early closed toe amputation was able to achieve a better wound healing rate at 90 days (89.5% vs. 68.6%; P<0.01) and a shorter median healing time (19 days vs. 62 days; P=0.01). Conclusion: There remains no established wound management for toe lesions associated with CLTI. Despite its several disadvantages including wound infection and possible foot deformity, early closed toe amputation for toe ulcers with suspected osteomyelitis can be considered a safe approach in terms of wound management.

Abstract
BACKGROUND Peripheral arterial disease (PAD) is associated with comorbid conditions and frailty. The role of pre-operative nutrition in these patients with PAD is not well characterized. This scoping review sought to describe the prevalence and prognostic implications of pre-operative malnutrition in patients undergoing vascular interventions for claudication or critical limb threatening ischemia (CLTI). METHODS Studies were systematically searched across 6 databases from inception to August 2021. Studies focusing on patients with claudication or CLTI undergoing open or endovascular procedures were included if pre-operative nutrition was measured and correlated with a clinical outcome. RESULTS Of 4186 records identified, 24 studies addressed the prevalence or prognostic impact of malnutrition in patients undergoing interventions for PAD. The proportion of women included in these studies ranged from 6% to 58%. The prevalence of pre-operative malnutrition ranged from 14.6% to 72%, and notably 7 different malnutrition assessments were used in these studies. Across all scales, pre-operative malnutrition was associated with at least one of the following outcomes: mortality, post-operative complications, length of stay, readmission rates, as well as delayed wound healing. CONCLUSION There are a variety of tools used to measure malnutrition in patients undergoing interventions for PAD. Our findings suggest that pre-operative malnutrition is associated with adverse clinical outcomes in patients undergoing open and endovascular procedures for claudication or CLTI, and there is lack of consensus on which tool to use. Clinicians and surgeons should be sensitized to the importance of assessing malnutrition preoperatively in adults undergoing interventions for PAD.

Abstract
OBJECTIVE Inframalleolar (IM) bypass has been reported to demonstrate acceptable patency and limb salvage in chronic limb-threatening ischemia (CLTI) patients. However, wound healing after IM bypass and comparisons between pedal artery (PA) bypass and pedal branch artery (PBA) bypass are lacking. METHODS We reviewed prospectively collected data from 208 consecutive patients after IM bypass performed over a period of six years. Patients were divided into two groups based on the distal anastomotic artery: the PA group (dorsal pedis artery or common plantar artery) and the PBA group (medial tarsal, lateral tarsal, medial plantar, and lateral plantar artery). The primary outcome was wound healing, and secondary outcomes included loss of patency and limb and life prognosis. RESULTS Of the 208 patients, 174 (74%) had PA bypass, whereas 34 (16%) had PBA bypass. Patients in the PBA group were significantly younger than those in the PA group (69 ± 7 vs. 73 ± 9, P = .03). Although early (30-day) graft failure was more common in the PBA group, late clinical outcomes, including the wound healing rate (79% in the PA group and 84% in the PBA group, P=.74), were similar between the two groups. The Global Limb Anatomic Staging System (GLASS) IM grade (HR, 0.73; 95% confidence interval [CI], 0.58-0.93: P=.006); wound, ischemia, and foot infection (WIfI) wound grade (HR, 0.67; 95% CI, 0.51-0.89: P<.01); and WIfI foot infection grade (HR, 0.79; 95% CI, 0.65-0.96: P=.02) were independent predictors of wound healing. CONCLUSIONS The current study revealed that wound healing in patients following PBA bypass was acceptable and comparable to that following PA bypass. In the modern era, including high prevalence of infrapopliteal angioplasty, our results could provide useful information to clinicians in actual clinical settings. Moreover, PBA bypass may be an alternative revascularization procedure to avoid major amputation when the pedal artery is occluded, such as in the GVG IM P2 grade. Prospective multicenter larger studies are warranted to confirm the findings of this study and to compare PBA bypass and IM EVT in anatomical "no-option" CLTI.

Mine K, Sugihara M, Fujita T, Kato Y, Gondo K, Arimura T, Takamiya Y, Shiga Y, Kuwano T, Miura SI. Impact of Controlling a Nutritional Status Score on Wound Healing in Patients with Chronic Limb-Threatening Ischemia after Endovascular Treatment. Nutrients 2021; 13:nu13113710. [PMID: 34835966 PMCID: PMC8625291 DOI: 10.3390/nu13113710] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Revised: 10/14/2021] [Accepted: 10/19/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Chronic limb-threatening ischemia (CLTI) is the most advanced stage of peripheral artery disease. Therefore, a multidisciplinary approach is necessary to avoid major amputation in CLTI patients. Malnutrition worsens the condition of CLTI patients, and therefore, it may be important to evaluate the nutritional status in patients with CLTI. This study was designed to evaluate the baseline patient characteristics and the influence of the controlling nutritional status (CONUT) score on the clinical results. Method and Results: A retrospective, single-center, non-randomized study was conducted to evaluate the associations of death, major amputation, and wound healing rate at 12 months with the CONUT score on admission. Consecutive CLTI patients (mean age 73.2 ± 10.4 years; 84 males) who underwent endovascular therapy (EVT) for infra-popliteal lesions at Fukuoka University Hospital from January 2014 to May 2019 were enrolled and divided into two groups (higher and lower CONUT score groups). The higher CONUT group showed a higher percentage of dialysis (66.7% vs. 33.9%, p < 0.001) and a higher clinical frailty scale (5.9 ± 1.4 vs. 4.9 ± 1.9, p = 0.005) than the lower CONUT group. Rates of amputation-free survival were 89.5% and 69.8% in the lower and higher CONUT groups, respectively. In addition, rates of wound healing at 12 months were 98.0% and 78.3% in the lower and higher CONUT groups, respectively. Multivariate regression analysis demonstrated that a higher CONUT score was an independent predictor for delayed wound healing (OR: 11.2; 95% CI: 1.29–97.5; p = 0.028). Conclusion: An assessment of the nutritional status using the CONUT score could be useful for predicting wound healing, and earlier nutritional intervention may improve the outcome of CLTI patients. Early examination and treatment, along with raising awareness of the issue, may be important for improving the prognosis.

Abstract
PURPOSE The purpose of this study was to investigate the relationship and to determine potential usefulness of serum albumin as a biomarker for predicting postoperative diabetic foot ulcer (DFU) healing. DESIGN A retrospective study. SUBJECTS AND SETTING The sample comprised 266 inpatients with type 2 diabetes receiving care in The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China. Among them, 174 had DFUs and underwent surgery for foot DFUs including amputation, skin grafting, and flap procedures. A comparison group consisted of 92 inpatients without a DFU or surgery. METHODS The association between healing and preoperative albumin levels was analyzed via a logistic regression model and receiver operating characteristic (ROC) curve. RESULTS The albumin value of patients with DFU grade 3 or more (3.23 ± 0.58 g/dL) was lower than that of patients with DFU grade 1-2 (3.58 ± 0.5 g/dL), and both were lower than that of the comparison group (3.89 ± 0.3 g/dL). Patients with a DFU with hypoalbuminemia (<3.5 g/dL) had a 2.5-fold higher risk of nonhealing at postoperative 28 days than patients with normal levels (odds ratio = 3.51; 95% confidence interval, 1.75-7.06; P < .001). For patients with a DFU overall, the ROC curve showed a preoperative albumin cutoff of 3.44 g/dL for DFU wound healing. CONCLUSIONS For patients with a DFU undergoing surgery, preoperative serum albumin may be used as a biomarker for predicting postoperative healing.

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
PURPOSE Clinical trials have demonstrated sustained benefits of drug-coated balloon (DCB) angioplasty compared with noncoated balloon angioplasty in symptomatic peripheral artery disease (PAD) presenting with femoropopliteal (FP) artery disease. However, there is still controversy whether particulate embolization caused by crystalline paclitaxel, the so-called "downstream effect," is adversely associated with clinical outcomes after use of FP DCB among chronic limb-threatening ischemia (CLTI) patients. The current RADISH (Roles of Angioplasty with Drug-coated balloon for chronic ISchemia in wound Healing) study investigated wound healing following DCB therapy vs non-DCB therapy for real-world CLTI patients presenting with FP lesions. MATERIALS AND METHODS This multicenter, retrospective study analyzed 927 patients with CLTI (mean age, 76±10 years; male, 57.8%; diabetes mellitus, 64.5%; dialysis, 50.7%) presenting with FP lesions and treated endovascularly via DCB (138 patients) vs non-DCB therapy (789 patients) between April 2014 and March 2019. The primary outcome measure was 1-year wound healing, while the secondary outcome measure was 1-year primary patency. Clinically-driven target lesion revascularization (CD-TLR), limb salvage and overall survival were also analyzed by using propensity score matching analysis. RESULTS The propensity score matching extracted 111 pairs (as many patients in the DCB group and 629 patients in the non-DCB group). The 1-year cumulative incidence of wound healing (95% CI) was 74.4% (62.6% to 82.5%) in the DCB group and 71.9% (60.4% to 80.1%) in the non-DCB group, with no significant intergroup difference (p=0.93). The DCB group had a higher rate of primary patency (p=0.002) and freedom from CD-TLR (p=0.010) than the non-DCB group, whereas there was no significant intergroup difference in limb salvage (p=0.21) or overall survival (p=0.93). CONCLUSION The current analysis of data from the RADISH study demonstrated that DCB therapy did not lead to delayed wound healing and reduced restenosis rate in CLTI patients presenting FP lesions. From this results, DCB therapy would be a reasonable treatment option for CLTI patients.

Abstract
OBJECTIVES The aim of this study was to determine the relationship between preoperative nutritional status and wound healing in patients undergoing surgical reconstruction for ischemic tissue loss. METHODS The preoperative nutritional status of patients who underwent surgical reconstruction for ischemic tissue loss for the years 2011-2018 was retrospectively estimated using the Controlling Nutritional Status (CONUT) score. Patients were allocated to two groups: Group I, normal nutrition or mild malnutrition (CONUT score ≤4), and Group II, moderate-to-severe malnutrition (CONUT score ≥5). Wound healing was set as the primary endpoint and major amputation and death as the secondary endpoints. The wound healing, limb salvage, and overall survival rates were calculated after two years using the Kaplan-Meier method, and Cox proportional hazards regression analysis was performed to determine which variables were independently associated with these outcomes. RESULTS Forty-eight patients with missing values for the CONUT score were excluded. A total of 174 limbs in 147 patients were studied (Group I: 115 limbs in 100 patients; Group II: 59 limbs in 47 patients). The mean duration of the study was 519 ± 270 days. The Kaplan-Meier curves showed that wound healing in Group I was superior to that in Group II (Group I vs. II: two-year wound healing, 97% vs. 79%; time to 50% wound healing, 83 vs. 150 days, p < 0.001), and multivariate analysis showed that the CONUT score was an independent predictor of wound healing (hazard ratio, 0.63; 95% confidence interval, 0.41-0.98; p = 0.038). CONCLUSIONS Patients with better preoperative nutritional status are more likely to experience wound healing earlier than those with excessive malnutrition.

Abstract
Aims:
Hemodialysis vintage and serum phosphorus levels adversely affect outcomes in patients on hemodialysis. Whether these factors have a similar prognostic impact on patients who are on hemodialysis and have chronic limb-threatening ischemia (CLTI) has not been systematically studied. We aimed to explore the risk factors, including hemodialysis vintage and serum phosphorus levels, on clinical outcomes after endovascular therapy (EVT) in hemodialysis patients with CLTI.
Methods:
The current study rerospectively analyzed 374 hemodialysis patients with CLTI presenting with ischemic tissue loss (age: 72.3±9.0 years, male: 73.3%, diabetes mellitus: 68.2%, Rutherford 5: 75.9%, 6: 24.1%, WIfI stage 4: 50.0%) primarily treated with EVT between April 2007 and December 2016. The primary outcome measure was 1-year amputation-free survival (AFS), while the secondary outcome measure was 1-year wound healing. Predictors for each outcome were evaluated by Cox proportional hazards model.
Results:
Multivariate analysis significantly associated longer hemodialysis vintages with higher serum phosphorus levels (hazard ratio [HR], 0.599; 95% confidence interval [CI], 0.394-0.910;
p
=0.016) with 1-year AFS. Longer vintages for hemodialysis with higher serum phosphorus levels were marginally, but not significantly, associated with 1-year wound healing. (HR, 0.684; 95% CI, 0.467–1.000;
p
=0.050).
Conclusion:
Longer hemodialysis vintages with higher serum phosphorus levels adversely affect outcomes after EVT for hemodialysis patients with CLTI presenting with ischemic tissue loss.

Abstract
PURPOSE To examine the long-term clinical outcomes of patients with anti-centromere antibody (ACA)-positive critical limb-threatening ischemia (CLTI) who were treated with endovascular therapy (EVT). MATERIALS AND METHODS This was a retrospective analysis using a database of 423 consecutive CLTI patients (543 limbs, Rutherford class 4-6) who underwent EVT between January 2011 and March 2013. The patients were divided into 2 groups: an ACA-positive group (10 limbs, 8 patients) and a control group (46 limbs, 43 patients). The control group was defined as female, non-dialysis, and those who were able to obtain a below-knee angiogram. RESULTS None of the 8 ACA-positive CLTI patients had previously been diagnosed as ACA positive. No significant difference was observed in the below-the-knee lesion distribution and severity between the ACA-positive group and the control group. The median observational period was 51 months. The survival rate was 54% in the ACA-positive group and 76% in the control group at 5 years after EVT (P = .732). The freedom from major amputation rate was 60% in the ACA-positive group and 91% in the control group at 5 years after EVT (P = .029). The technical EVT success rate in the ACA-positive group was 70% (7/10). Of the successful EVT cases, 71% (5/7) of patients achieved complete wound healing or rest pain relief; however, 60% (3/5) had a recurrence of wounds. CONCLUSIONS In a series of ACA-positive patients with CLTI, successful EVT had acceptable outcomes with respect to wound healing with short-term results. However, the major amputation rate for ACA-positive patients was high in long-term follow-up.

Abstract
Background Acute limb ischemia (ALI) and critical limb ischemia (CLI) following ALI are life-threatening diseases. The rare potential causes of ALI include hypercoagulable state diseases, such as antiphospholipid syndrome (APS) and essential thrombocythemia (ET). Hypercoagulability often make revascularization for arterial occlusion, especially associated with infrapopliteal lesions, difficult. This is because the vessels have poor run-off, and elevated peripheral vascular resistance associated with microcirculation failure, due to a high thrombus burden. There is no established treatment for this issue. Case presentation A 45 years-old and a 56 years-old male suffered from thrombotic arterial occlusion as a first manifestation of APS and ET, respectively. Combination therapy with aggressive anti-thrombotic therapy and revascularization, such as endovascular therapy and surgical thrombectomy based on the angiosome concept, was performed. However, the high thrombus burden caused a poor pedal outflow, and significant limb ischemia remained. Additional pedal artery angioplasty was performed to improve residual limb ischemia in each case and provided sufficient blood flow to the foot. Conclusion The pedal artery angioplasty for thrombotic pedal artery occlusion cases, associated with hypercoagulable state diseases, seems to be a treatment option for relieving residual limb ischemia.

A model for predicting the time of early symptomatic restenosis after infrapopliteal angioplasty in patients with critical limb ischemia. Cardiovasc Interv Ther 2020; 36:330-337. [PMID: 32683547 DOI: 10.1007/s12928-020-00691-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Accepted: 07/11/2020] [Indexed: 10/23/2022]
Abstract
The objective of this study is to develop a model for predicting the time of early symptomatic (delayed or nonhealing wound) restenosis after infrapopliteal angioplasty in patients with critical limb ischemia (CLI). This is a single-center retrospective cohort study evaluating 60 de novo infrapopliteal lesions of 38 limbs in 35 patients with CLI, who underwent successful endovascular treatment (EVT) from October 2016 to December 2018 and follow-up angiography within 3 months from the procedure. Outcome measures were binary restenosis at follow-up angiography and clinical outcome at 3 months. Patient/limb/lesion characteristics were compared between the restenosis and non-restenosis groups. Angiographic restenosis predictors were assessed to develop a model for predicting the time of restenosis using multinomial logistic regression. The restenosis rate at follow-up angiography (median time, 41 days [IQR 27-58 days]) was 38% (23/60). After adjustment for covariables, longer period between EVT and follow-up angiography and lower C-reactive protein (CRP) were the predictors of angiographic restenosis. We developed a model for predicting the time of early symptomatic restenosis with a probability of 70%: "Days = 200 - 2.1 age - 13 CTO + 3.3 CRP" (R2 = 0.81, RMSE = 0.27), e.g., 80 years old, CTO (+), CRP 4.4 mg/dl: 32.2 days. The predictive model including age, CTO, and CRP might allow estimation of the period for the angiographic restenosis development.

Predictors of hospital expenses and hospital stay among patients undergoing total laryngectomy: Cost effectiveness analysis. PLoS One 2020; 15:e0236122. [PMID: 32673371 PMCID: PMC7365401 DOI: 10.1371/journal.pone.0236122] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Accepted: 06/29/2020] [Indexed: 12/03/2022] Open
Abstract
Objective To determine the predictive factors of postoperative hospital stay and total hospital medical cost among patients who underwent total laryngectomy. Methods A total of 213 patients who underwent total laryngectomy in a tertiary referral center for tumor ablation were enrolled retrospectively between January 2009 and May 2018. Statistical analyses including Pearson's chi-squared test were used to determine whether there was a significant difference between each selected clinical factors and outcomes. The outcomes of interest including postoperative length of hospital stay and inpatient total medical cost. Logistic regression analyses were performed to reveal the relationship between clinical factors and postoperative length of hospital stay or total inpatient medical cost. Results Preoperative radiotherapy (p = 0.007), method of wound closure (p < 0.001), postoperative serum albumin level (p = 0.025), and postoperative serum hemoglobin level (p = 0.04) were significantly associated with postoperative hospital stay in univariate analysis. Postoperative hypoalbuminemia (odds ratio [OR]: 2.477; 95% confidence interval [CI]: 1.189–5.163; p = 0.015) and previous radiotherapy history (OR 2.194; 95% CI: 1.228–3.917; p = 0.008) are independent predictors of a longer postoperative hospital stay in multiple regression analysis. With respect to total inpatient medical cost, method of wound closure (p < 0.001), preoperative serum albumin level (p = 0.04), postoperative serum albumin level (p < 0.001), and history of liver cirrhosis (p = 0.037) were significantly associated with total inpatient medical cost in univariate analysis. Postoperative hypoalbuminemia (OR: 6.671; 95% CI: 1.927–23.093; p = 0.003) and microvascular free flap reconstruction (OR: 5.011; 95% CI: 1.657–15.156; p = 0.004) were independent predictors of a higher total inpatient medical cost in multiple regression analysis. Conclusions Postoperative albumin status is a significant factor in predicting prolonged postoperative hospital stay and higher inpatient medical cost among patients who undergo total laryngectomy. In this cohort, the inpatient medical cost was 48% higher and length of stay after surgery was 35% longer among hypoalbuminemia patients.

Abstract
Aims Lower extremity arterial disease (LEAD) and left ventricular diastolic dysfunction (LVDD) share many risk factors, but the characteristics of LVDD and its association with prognosis in patients with LEAD have not been fully examined. Methods and results We investigated the impact of LVDD on the clinical outcomes in LEAD patients. LVDD was classified according to the newest suggested classification by the American Society of Echocardiography. Survival analysis for mortality (primary endpoint) and major adverse cardiac events (MACE; secondary endpoint) was calculated with all clinical variables and adjusted by multivariate Cox regression. We consecutively enrolled 221 controls and 464 LEAD patients from outpatient clinics and hospitals. The prevalence of LVDD was proportional to the severity of LEAD defined by the Rutherford class. The difference of LVDD severity is significant when compared with the control and LEAD patients or LEAD patients who underwent endovascular therapy (EVT), and it is also proportional to the LEAD severity. The grade of LVDD was a significant factor in predicting MACE and mortality in LEAD patients after multivariate Cox regression analysis [hazard ratio (HR) = 2.11, 95% CI = 1.47–2.83, P = 0.026; HR = 1.47, 95% CI = 1.02–2.02, P = 0.041]. This impact remained significant in LEAD patients who underwent EVT. Conclusions The degree of LVDD may predict MACE and mortality in LEAD patients. Whether early identification of LVDD in LEAD patients is helpful warrants further large‐scale prospective randomized studies.

Abstract
Purpose: To investigate the prognostic impact of infrapopliteal (IP) artery anatomic severity according to the Global Limb Anatomic Staging System (GLASS) on delayed wound healing in patients with chronic limb-threatening ischemia (CLTI). Materials and Methods: This study retrospectively analyzed 639 limbs with tissue loss in 484 CLTI patients (mean age 74±10 years; 300 men) presenting IP lesions treated with endovascular therapy between April 2010 and December 2015. Two-thirds of patients had diabetes (323, 67%) and over half were on hemodialysis (255, 53%). More than a third of the limbs (251, 39%) were classified as clinical stage 4 according to the Wound, Ischemia, and foot Infection (WIfI) system. IP anatomic severity was classified based on preprocedural angiography according to the GLASS. Severity of arterial calcification was assessed using high-intensity fluoroscopy and classified into 3 groups: none (grade 0), unilateral (grade 1), and bilateral (grade 2). Poor below-the-ankle (BTA) runoff was defined as the lack of a pedal arch with 0 to 1-vessel runoff within the dorsal pedis artery and the lateral and medial plantar arteries. The outcome measure was 1-year wound healing. The association of anatomic characteristics with delayed wound healing was evaluated using Cox proportional hazards regression analysis. Outcomes are presented as the adjusted hazard ratio (HR) with 95% confidence interval (CI). Results: During a mean follow-up of 22±19 months, the 1-year cumulative wound healing rate was estimated to be 59.0% (95% CI 54.5% to 63.5%). Multivariable analysis demonstrated independent associations between delayed wound healing and IP calcification grade (HR 1.24, 95% CI 1.02 to 1.50, p=0.027) and poor BTA runoff (HR 1.39, 95% CI 1.04 to 1.85, p=0.025) but not the GLASS IP grade (HR 0.92, 95% CI 0.82 to 1.14, p=0.21). Conclusion: The current study revealed that IP arterial calcification and poor BTA runoff were significantly associated with delayed wound healing, whereas the GLASS was not predictive of wound healing.

Abstract
Objective: Clinical guidelines have long recommended referring patients with clerical limb ischemia (CLI) to a vascular specialist early in the course of their disease to plan for revascularization options. However, no data were so far available on how promptly CLI patients were referred to a vascular center in the real-world settings in Japan. This study aimed to survey the duration from wound occurrence to referral to a vascular center in CLI patients in Japan. Materials and Methods: We analyzed a database of a prospective, multicenter registry in Japan, including 428 CLI patients presenting ischemic wounds and referred to vascular centers. The duration of the wound occurrence was surveyed at registration. Results: The wound duration exceeded 1 month in 58.2% [95% confidence interval: 53.2% to 63.1%] of the patients, and 3 months (i.e., one season) in 15.9% [12.4% to 19.4%]. No clinical features were significantly associated with the wound duration. The wound duration was independently associated with the wound severity evaluated using the Wound, Ischemia, and foot Infection classification system (P=0.030). Conclusion: A substantial number of CLI patients referred to vascular centers had a long duration of wounds, i.e., time from wound occurrence to the referral.

Abstract
Purpose: To identify lower limb 2-dimensional (2D) perfusion angiographic parameters that are related to skin perfusion pressure (SPP), a predictor of wound healing in patients with chronic limb-threatening ischemia (CLTI) undergoing below-the-knee (BTK) endovascular treatment (EVT). Materials and Methods: Thirty-three consecutive patients (mean age 74.5 years; 18 men) with 47 isolated BTK lesions in 33 limbs (Rutherford category 3–5) underwent EVT. Dorsal and plantar SPPs were measured before EVT and the day after. The indexed blood flow below the ankle was measured using 2D perfusion angiography before and after EVT to determine changes in perfusion parameters [arrival time (AT), time to peak, wash-in rate, mean transit time, and width and area under the time-density curve] at rest vs during hyperemia induced with a 20-mg intra-arterial papaverine infusion. Correlations between the 2D perfusion parameters and SPPs were assessed using the Pearson coefficient. The cutoff points to predict mean SPPs >40 mm Hg were analyzed using a receiver operating characteristic curve; outcomes are reported as the area under the curve (AUC) with 95% confidence interval (CI). Results: After EVT at rest and during hyperemia, only AT was significantly changed, although hyperemia produced significant changes in all the pre-/post-EVT 2D perfusion parameters except the wash-in rate. Dorsal and plantar SPPs after EVT were significantly increased and correlated with hyperemic AT and the AT ratio (hyperemia/at rest values) below the ankle. Hyperemic ATs <6.3 seconds and AT ratios <0.78 were predictive factors for a mean SPP >40 mm Hg, with AUCs of 0.83 (95% CI 0.67 to 0.99) and 0.78 (95% CI 0.61 to 0.95), respectively. Conclusion: Hyperemic ATs <6.3 seconds or AT ratios <0.78 below the ankle may be essential to obtain sufficient SPPs for limb salvage in BTK lesions. Thus, the use of 2D perfusion angiography enabled the monitoring of lower limb tissue perfusion throughout EVT and may thereby optimize treatment of CLTI.

Abstract
BACKGROUND Arterial reconstruction (AR) for limb ischemia may improve ambulatory function (AF) and health-related quality of life (HR-QoL). However, the efficacy of AR in terms of HR-QoL varies in studies, probably because of cohort differences in disease severity, hemodynamic outcomes, and observation duration. We assessed HR-QoL for patients with various severities of ischemia in a 3-year observational study. METHODS We conducted a single-center 3-year observational study using Short Form 36 in patients with chronic limb ischemia. Between 2001 and 2009, 515 consecutive patients had AR, and 330 who underwent elective AR consented to the study. Of the 330 patients (claudicants 49%, critical limb ischemia [CLI] 51%), 307 underwent bypass and 23 endovascular therapy. Postal questionnaires were sent after AR, and 8 domains, the physical and mental component summary (PCS and MCS) scores, and the patient-reported AF were compared, and negative predictors were identified. RESULTS Overall, the MCS was minimally affected, but AF and the PCS were impaired. After AR, these measures were significantly improved, and maximum recovery was attained at 6 months. In subgroup analysis, significant predictors of a negative impact on postoperative PCS included age ≥80, CLI, physical aftereffects of stroke (PAS), and previous major amputation (PMA). Of these, PMA was associated with the lowest PCS score, followed by PAS; for these patients, AR contributed minimally to HR-QoL recovery. PCS scores of claudicants attained a maximum value at 6 months; however, PCS scores of CLI patients were significantly lower than intermittent claudication patients (P < 0.0001), and patients with major tissue loss required 2 years to attain maximum PCS recovery. CONCLUSIONS This 3-year observational study verified the efficacy of AR in improving AF and HR-QoL. Age ≥80, CLI, PAS, and PMA were definitive predictors, and for patients with the latter 2, AR contributed minimally to improving HR-QoL.

Abstract
Purpose: To examine the efficacy of pedal artery angioplasty (PAA) for chronic limb-threatening ischemia (CLTI) according to the severity of inframalleolar disease. Methods: In total, 257 consecutive CLTI patients (mean age 73.2 years; 175 men) with de novo infrapopliteal and inframalleolar artery disease were enrolled from the retrospective RENDEZVOUS registry. Inframalleolar artery disease was classified as moderate (Kawarada type 2, 144 patients) or severe (Kawarada type 3, 113 patients). PAA was performed in 140 patients: 66 (45.8%) with moderate disease and 74 (65.5%) with severe disease. The remaining 117 patients (78 with moderate disease and 39 with severe disease) underwent interventions that did not include PAA. The primary outcomes were the wound healing and limb salvage rates at 12 months after the initial treatment. The outcomes of the PAA and no-PAA groups were examined to determine any correlation between treatment efficacy and baseline disease severity. Results: The success rates of PAA among the patients with moderate and severe inframalleolar disease were 89.4% and 87.8%, respectively (p=0.683). The wound healing rate at 12 months was significantly higher in the PAA group than in the no-PAA group regardless of the severity of inframalleolar disease [moderate: 58.8% vs 40.0% (p=0.049); severe: 59.6% vs 33.2% (p=0.021), respectively]. The worst limb salvage rate (76.9%) was seen among patients in the no-PAA group with severe inframalleolar disease (no-PAA/moderate: 94.8%; PAA/moderate: 90.9%; and PAA/severe: 87.8%, p=0.028). Conclusion: PAA improves the wound healing rate of patients with CLTI regardless of the severity of inframalleolar disease. This treatment modality also might improve limb salvage rates in patients with severe inframalleolar disease affecting both the anterior and posterior pedal circulations.

Abstract
BACKGROUND It has been reported that the Controlling Nutritional Status (CONUT) score, calculated using the serum albumin concentration, total peripheral lymphocyte count, and total cholesterol concentration, is a valuable nutritional status index. In the present study, we assessed whether the CONUT score was a significant predictor of complete ulcer healing in patients with critical limb ischemia (CLI). METHODS In this retrospective, single center, cohort study, conducted from January 2013 to June 2018, we treated 112 limbs of 89 patients with Fontaine 4 CLI at the Department of Surgery and Science, Graduate School of Medical Sciences, Kyushu University, Japan. The primary endpoint of the study was complete ulcer healing after revascularization, and the secondary endpoint was amputation-free survival (AFS). RESULTS The mean follow-up time was 17.8 months. Complete ulcer healing was achieved during the follow-up period in 91 (81.2%) limbs. The median ulcer healing time was 104 days (range, 16-574 days). In multivariate analysis, improvement of lower skin perfusion pressure ratio of <1, end-stage renal disease, and high CONUT score (>4) were predictive of incomplete ulcer healing in patients with Fontaine 4 CLI. In addition, the AFS rate was significantly better in patients with a CONUT score ≤4 than in those with a CONUT score >4. CONCLUSIONS The CONUT score was associated with postprocedure ulcer healing and long-term limb retention in patients who underwent revascularization. The management of CLI involving ischemic foot ulcers may require ongoing consideration of nutritional status.

Abstract
Background Perineal wound complications are a long-lasting issue for abdominoperineal resection (APR) patients. Complication rates as high as 60% have been reported, with the most common complication being delayed perineal wound healing. The aim of this study was to identify risk factors for delayed perineal wound healing and its impact on prolonged hospital stay. Methods We included low rectal tumor patients who underwent APR at a referral medical center from April 2002 to December 2017; a total of 229 patients were included. The basic characteristics and surgical outcomes of the patients were analyzed to identify risk factors for delayed perineal wound healing (> 30 days after APR) and prolonged hospital stay (post-APR hospital stay > 14 days). Results All patients received primary closure for their perineal wound. The majority of patients were diagnosed with adenocarcinoma (N = 213, 93.1%). In the univariate analysis, patients with hypoalbuminemia (albumin < 3.5 g/dL) had an increased risk of delayed wound healing (39.5% vs. 60.5%, P = 0.001), which was an independent risk factor in the multivariable analysis (OR 2.962, 95% CI 1.437–6.102, P = 0.003). Patients with delayed wound healing also had a significantly increased risk of prolonged hospital stay (OR 6.404, 95% CI 3.508–11.694, P < 0.001). Conclusions Hypoalbuminemia was an independent risk factor for delayed wound healing, which consequently led to a prolonged hospital stay. Further clinical trials are needed to reduce the incidence of delayed perineal wound healing by correcting albumin levels or nutritional status before APR.

Abstract
Recently, there have been increasing opportunities to treat patients with peripheral arterial disease. Of those patients, both pathological conditions, such as acute limb ischemia (ALI) and chronic critical limb ischemia (CLI), are closely associated with high risks of major amputation, disability and death. We encountered a very rare case of CLI subsequent to ALI. An 83-year-old male showed the sudden onset of ALI, probably due to thromboembolism from an abdominal aortic aneurysm during an operation for gastric cancer. The patient was referred to another hospital for Fogarty thrombectomy. About 1 month after ALI onset, necrosis of the left first toe gradually progressed. On angiography of the left lower limb, we noted occlusions of both anterior and posterior tibial arteries. Then, we successfully conducted balloon angioplasty for the below-the-knee arteries. Thereby, favorable blood flow was achieved, which led to successful wound healing without amputations.

Editor's Choice - Impact of Endovascular Pedal Artery Revascularisation on Wound Healing in Patients With Critical Limb Ischaemia. Eur J Vasc Endovasc Surg 2019; 58:854-863. [PMID: 31653609 DOI: 10.1016/j.ejvs.2019.07.034] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2019] [Revised: 06/23/2019] [Accepted: 07/05/2019] [Indexed: 11/26/2022]
Abstract
OBJECTIVE The present study investigated the impact of endovascular pedal artery revascularisation (PAR) on the clinical outcomes of patients with critical limb ischaemia (CLI). METHODS This retrospective analysis of a single centre cohort included 239 patients who underwent endovascular revascularisation of infrapopliteal arteries for a chronic ischaemic wound. PAR was attempted in 141 patients during the procedure. After propensity score matching, there were 87 pairs of patients with and without PAR. RESULTS After the matching, the two groups showed balanced baseline clinical and lesion characteristics. PAR was achieved in 60.9% of the PAR group. Direct angiosome flow was more frequently obtained in the PAR group than in the non-PAR group (81.6% vs. 34.5%; p < .001). Subintimal angioplasty (47.1% vs. 29.9%; p = .019) and pedal-plantar loop technique (18.4% vs. 0%; p < .001) were more frequent in the PAR group. At the one year follow up, the PAR group showed greater freedom from major amputation (96.3% vs. 84.2%; p = .009). The wound healing rate, overall survival, major adverse limb event, and freedom from re-intervention did not differ significantly between the two groups. However, the patient subgroup with successful PAR showed a higher wound healing rate than the non-PAR group (76.0% vs. 67.0%; p = .031). In a multivariable Cox proportional hazards regression model, successful PAR (hazard ratio [HR] 1.564, 95% confidence interval [CI] 1.068-2.290; p = .022) was identified as an independent factor associated with improved wound healing, whereas gangrene (HR 0.659, 95% confidence interval [CI] 0.471-0.923; p = .015), C reactive protein >3 mg/dL (HR 0.591, 95% CI 0.386-0.904; p = .015), and pre-procedural absence of pedal arch (HR 0.628, 95% CI 0.431-0.916; p = .016) were associated with impaired wound healing. CONCLUSION Successful PAR significantly improved wound healing in patients with CLI. Thus, efforts should be made to revascularise the pedal arteries, especially when the pedal arch is completely absent.

Abstract
Endovascular therapy (EVT) plays a major role in the treatment of critical limb ischemia (CLI). The latest guidelines state that the angiosome concept should be considered when performing revascularization of infrapopliteal lesions in patients with CLI. There have been several reports both of favorable and unfavorable results of angiosome-guided EVT. Based on previous reports, angiosome-guided EVT tends to improve wound healing (WH) rather than amputation-free survival and overall survival. In addition, indirect revascularization based on the angiosome concept with a good collateral flow may achieve good WH comparable to that achieved by direct revascularization. In the future, rather than just debating the effectiveness/ineffectiveness of the angiosome concept, it will be desirable to investigate the patient and lesion characteristics that may have significant influences on WH after angiosome-guided EVT and to apply the results to clinical practice.

Additional Risk Stratification Using Local and Systemic Factors for Patients with Critical Limb Ischaemia Undergoing Endovascular Therapy in the WIfI Era. Eur J Vasc Endovasc Surg 2019; 58:548-555.

Abstract
OBJECTIVES While current guidelines describe the importance of assessing limb characteristics for predicting limb prognosis in patients with critical limb ischaemia (CLI), several reports have also suggested that systemic factors are associated with limb prognosis. The aim of this study was to evaluate whether systemic factors have the same impact on wound healing as limb characteristics in CLI patients undergoing endovascular therapy. METHODS A total of 735 patients who were treated for the first time for CLI with tissue loss between April 2010 and December 2015 were extracted from a prospective registry and data for the Wound, Ischaemia, and foot Infection (WIfI) classification were searched retrospectively. The predictors of wound healing were explored with Cox proportional hazards regression. RESULTS The one year wound healing rate was 60.2% in WIfI stage 1-3 patients and 53.6% in WIfI stage 4 (p = .01). In WIfI stage 1-3, no systemic factors were significantly associated with wound healing, whereas, in WIfI stage 4 patients, non-ambulatory status [hazard ratio (HR) 1.98; 95% confidence interval (CI) 1.37-2.84], haemodialysis (HR 1.90; 95% CI 1.33-2.72) and an albumin level under 3.0 g/dL (HR 1.53; 95% CI 1.02-2.31), were identified as independent risk factors for failure to achieve wound healing. If none or one of these risk factors were present, wound healing was comparable with WIfI 4 and WIfI 1-3 patients (67.7% vs. 63.6%, p = .89), whereas in patients with two or more risk factors wound healing was worse in WIfI 4 than in WIfI 1-3 patients (35.7% vs. 49.5%, p = .01). CONCLUSION Non-ambulatory status, haemodialysis, and a low albumin level were additional systemic risk factors for impaired wound healing in patients with WIfI stage 4. The wound healing rate in WIfI stage 4 patients with one or fewer of these risk factors was comparable to that in WIfI stage 1-3.

Abstract
OBJECTIVES After surgical or endovascular revascularization, some ischemic lesions will not heal, while some others will heal at a variable period of time from the intervention, indicating a multifactorial interaction between local and systematic "wound healing-promoting" factors. Our objective was to identify predictors of wound healing following revascularization for chronic limb-threatening ischemia (CLTI). METHODS A literature review was performed to identify published research concerning clinical, biochemical, and noninvasive methods as predictors of wound healing time and wound-free period after surgical and endovascular revascularization for CLTI. RESULTS Our review indicated that potential predictors included local wound factors, wound depth, patient's comorbidities, medications, smoking and alcohol abuse, poor vessel runoff, and direct versus indirect revascularization. Among the clinical biomarkers, platelet-derived growth factor, transforming growth factor β, basic fibroblast growth factor, tumor necrosis factor α, interleukin (IL) 1, and IL-6 have been proposed as potential predictors. Furthermore, the potential of noninvasive microcirculation assessment to predict proper wound healing has been the topic of extensive investigation. Among the novel methods, transcutaneous measurement of oxygen partial pressure, skin perfusion pressure, oxygen-to-see method, indocyanine green fluorescence imaging, and multispectral optoacoustic tomography have shown promising results. CONCLUSIONS The risk factor profile of an ischemic lesion in the lower extremities with a delayed/failed healing response, following a successful revascularization, is not fully clarified. Although many predictors have been assessed so far, further research needs to be done to identify the optimal clinical and biochemical indices and the noninvasive technique assessing the microcirculation that is associated with complete wound healing.

Abstract
Maintenance of blood flow in the wound area is required to heal wounds of critical limb ischemia (CLI) in dialysis patients. However, many dialysis patients have both a stenotic lesion in below-knee blood vessels and a cardiovascular event as complications, and thus, it may be difficult to ensure sufficient blood flow. Therefore, many deaths occur because of problems with wound healing. The aim of this study is to identify the optimal treatment, including revascularisation and amputation, from the perspective of wound healing by analysing the survival of hemodialysis patients with CLI who had healed or unhealed wounds in a lower extremity. The subjects were 52 patients who received maintenance dialysis at our clinic, including 27 with healed CLI wounds and 25 with unhealed CLI wounds. The Kaplan-Meier method was used to compare survival between the two groups. Multivariate analysis was conducted to examine the effect of an unhealed wound on mortality. The mean follow-up period was 1.7 ± 1.1 years. In the unhealed wound group, the 1-, 2-, and 3-year survival rates were 48%, 20%, and 12%, respectively. The overall survival rate was significantly lower in the unhealed wound group compared with the healed wound group (12% vs 63%, P = .0002 by log-rank test). In multivariate analysis, unhealed CLI wounds had a significant independent association with mortality (hazard ratio 3.32; 95% confidence interval [CI]: 1.41-8.77, P = .0054). In this study, the 3-year survival rate suggested a significantly poorer prognosis of hemodialysis patients with unhealed CLI wounds compared with those with healed wounds. An unhealed wound is an independent risk factor for mortality in hemodialysis patients with CLI.

Abstract
Abstract. Peripheral arterial disease (PAD) management is exceptionally challenging. Despite advances in diagnostic and therapeutic technologies, long-term vessel patency and limb salvage rates are limited. Patients with PAD frequently require extensive workup with noninvasive tests and imaging to delineate their disease and help guide appropriate management. Ultrasound and computed tomography are commonly ordered in the workup of PAD. Magnetic resonance imaging (MRI), on the other hand, is less often acknowledged as a useful tool in this disease. Nevertheless, MRI is an important test that can effectively characterize atherosclerotic plaque, assess vessel patency in highly calcified disease, and measure lower extremity perfusion.
