Outcomes and predictors of amputation-free survival in patients undergoing below-knee popliteal-distal bypass. J Vasc Surg 2024; 79:1163-1169.e2. [PMID: 38244642 DOI: 10.1016/j.jvs.2023.12.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 12/15/2023] [Accepted: 12/17/2023] [Indexed: 01/22/2024]
Abstract
OBJECTIVE The infrageniculate popliteal artery is a potential source for inflow in lower extremity bypass surgery in patients with isolated tibial artery disease. The objective of our study was to assess the short- and long-term outcomes of popliteal-distal bypasses using data from the Vascular Quality Initiative (VQI). METHODS The VQI registry was queried between 2003 and 2021 for patients undergoing surgical revascularizations with the below-knee popliteal artery serving as inflow. Demographics, comorbidities, intraoperative characteristics, and postoperative complications were analyzed. Kaplan-Meier models were used to estimate amputation-free survival, survival, and freedom from amputation. Cox regression analysis was conducted to determine factors associated with major amputation or death. RESULTS A total of 1884 procedures were analyzed. The mean age of the included patients was 67.7 years. The most frequently observed preoperative comorbidities included insulin-dependent diabetes (52.3%), coronary disease (32.4%), and end-stage renal disease (14.4%). Of all the patients, 670 (35.6%) had a history of ipsilateral endovascular intervention. The procedures were performed for a variety of indications, including tissue loss (84.3%), rest pain (10.9%), and claudication (4.8%). Intraoperatively, the outflow targets were the dorsalis pedis (31.4%), the posterior tibial (24.4%), and the anterior tibial arteries (15.6%). Vein conduit was used in 92.1% of cases. The rate of perioperative myocardial infarction (MI) was 2.4%, and the 30-day mortality was 1.9%. The median length of follow up was 371 days. Amputation-free survival was found to be 85.6% (95% confidence interval [CI], 84.0%-87.2%) at 6 months and 78.6% (95% CI, 76.6%-80.4%) at 12 months. Survival was found to be 93.4% (95% CI, 92.2%-94.5%) at 6 months and 88.6% (95% CI, 87.1%-90.0%) at 12 months. Freedom from amputation was found to be 92.0% (95% CI, 90.7%-93.3%) at 6 months and 89.0% (95% CI, 87.3%-90.4%) at 12 months. Cox regression analysis demonstrated that age greater than 65 years, congestive heart failure, coronary artery disease, and end-stage renal disease were associated with a higher risk of major amputation or death (P < .05). CONCLUSIONS Below-knee popliteal-distal bypass is a safe and effective approach to treat severe tibial vessel occlusive disease in this challenging patient cohort. Patients exhibited low perioperative complication rates and good amputation-free survival at 1 year.

Abstract
BACKGROUND This review will discuss the use of distal adjuncts for improving graft patency in high-risk lower extremity bypasses. METHODS Factors that contribute to the increased risk of failure in high-risk lower extremity bypasses, such as the use of nonautogenous conduits, the creation of bypasses to very distal arterial targets, and bypasses in patients with significant tibial arterial disease, will be discussed. RESULTS The use of surgical techniques such as creating venous cuffs, venous patches, and arteriovenous fistulas have been shown to improve the patency of high-risk bypasses. CONCLUSIONS Despite the increased risk of failure, the use of surgical adjuncts such as cuffs, patches, and arteriovenous fistulas can improve the patency rates of high-risk lower extremity bypasses.

Anatomical Distribution Patterns of Peripheral Arterial Disease in the Upper Extremities According to Patient Characteristics: A Retrospective Cohort Study. Vasc Health Risk Manag 2023; 19:871-883. [PMID: 38173811 PMCID: PMC10762427 DOI: 10.2147/vhrm.s440408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 12/21/2023] [Indexed: 01/05/2024] Open
Abstract
Purpose Peripheral arterial disease (PAD) greatly affects the patients' quality of life. We aimed to investigate the affected anatomical sites and distribution patterns in upper extremity PAD using computed tomography angiography (CTA). Furthermore, we sought to identify the correlations between patient characteristics and the identified patterns. Patients and Methods This was a retrospective chart review of upper limb CTA findings from patients with symptomatic PAD aged >18 years. Significant variables from univariate logistic regression analysis were further tested using multivariate logistic regression analysis. Statistical significance was set at p < 0.05, with confidence intervals of 95%. Results The mean age of the 102 included patients with upper extremity PAD was 55.45 years. Laterality analysis revealed that the upper left limb segments were more affected than the upper right limb segments (42 vs 63; left-to-right ratio, 3:2). The forearm was the segment most affected by stenotic PAD (62 segments, 3.37%). The arm was the segment most affected by occlusive PAD (14 segments, 0.76%). Diabetes mellitus (DM) and hypertension (HTN) were significant predictors of PAD (p = 0.046). In patients with DM, the occlusive form of PAD was dominant in the arm (18.18%); however, the stenotic form prevailed in the forearm (72.72%). In patients with HTN, the occlusive form of PAD was predominant in the arm (45.45%); however, the stenotic form tended to occur in the arm and forearm (90.90%). Conclusion The distribution patterns of upper extremity PAD are linked to its underlying pathophysiology. HTN and DM are the most frequent comorbidities in patients with upper extremity PAD. Angiographically, PAD in these patients is likely to present as stenosis rather than as occlusion. This is vital for interventionists who deviate from radial arterial access in patients with PAD. Therefore, targeted screening standards are required, and further studies on PAD are warranted.

Abstract
OBJECTIVE This retrospective cohort study investigated the anatomical distribution, severity, and outcome of peripheral artery disease (PAD) in Aboriginal and Torres Strait Islanders compared with non-indigenous Australians. METHODS The distribution, severity, and outcome of PAD were assessed using a validated angiographic scoring system and review of medical records in a cohort of Aboriginal and Torres Strait Islander and non-indigenous Australians. The relationship between ethnicity and PAD severity, distribution, and outcome were examined using non-parametric statistical tests, Kaplan-Meier and Cox proportional hazard analyses. RESULTS Seventy-three Aboriginal and Torres Strait Islanders and 242 non-indigenous Australians were included and followed for a median of 6.7 [IQR 2.7, 9.3] years. Aboriginal and Torres Strait Islander patients were more likely to present with symptoms of chronic limb threatening ischaemia (81% vs. 25%; p < .001), had greater median [IQR] angiographic scores for the symptomatic limb (7 [5, 10] vs. 4 [2, 7]) and tibial arteries (5 [2, 6] vs. 2 [0, 4]) and had higher risk of major amputation (HR 6.1, 95% CI 3.6 - 10.5; p < .001) and major adverse cardiovascular events (HR 1.5, 95% CI 1.0 - 2.3; p = .036) but not for revascularisation (HR 0.8, 95% CI 0.5 - 1.3; p = .37) compared with non-indigenous Australians. The associations with major amputation and major adverse cardiovascular events were no longer statistically significant when adjusted for limb angiographic score. CONCLUSION Compared with non-indigenous patients, Aboriginal and Torres Strait Islander Australians had more severe tibial artery disease and a higher risk of major amputation and major adverse cardiovascular events.

Abstract
Purpose Peripheral arterial disease (PAD) is a common disease with multiple risk factors and affects patients worldwide. Several international studies have established correlations between anatomical topography/distribution of atherosclerosis and comorbidities in patients with PAD. In this cohort study, we aimed to analyze the patterns of atherosclerosis (site, distribution, and degree) in patients who underwent lower limb computed tomography angiography and arterial angiography by identifying the atherosclerotic plaque(s) that were possibly responsible for thrombi. Additionally, we aimed to determine any relationship between comorbidities and identified patterns. Patients and Methods Between January 2015 and January 2021, we retrospectively recruited 140 patients at King Fahd Hospital of the University of Saudi Arabia. Data collected included patient characteristics, risk factors, and metabolic disorders, such as hypertension (HTN), diabetes mellitus (DM), dyslipidemia, and chronic kidney disease. Patients with incomplete records or unavailable radiological images were excluded. Results The infrapopliteal territory was the most common segment that was affected. HTN, DM, and dyslipidemia were found in 81.4%, 77.9%, and 62.9% of patients, respectively. Correlation analyses revealed that DM was the only independent metabolic disorder associated with a PAD distribution pattern in the femoropopliteal segment (p=0.039), thus denoting distal involvement. No significant association was found between PAD distribution and the severity of stenosis. Conclusion Segmental involvement in PAD varies with the risk factors and metabolic comorbidities present in patients. DM is an independent predictor of the anatomical distribution of PAD. The identification of such an anatomical distribution is paramount for screening procedures, early detection of disease, and prevention of complications, particularly limb amputation.

Abstract
Background Atherosclerosis risk factors can have different impacts on cardiovascular diseases and on the anatomical distribution of Peripheral Arterial Disease (PAD). Objectives To study the influence of atherosclerosis risk factors on the anatomical distribution of PAD in patients with chronic limb-threatening ischemia (CLTI). Methods We performed an observational, cross-sectional, and analytical study that included 476 hospitalized patients with CLTI due to PAD. We compared the presence of atherosclerosis risk factors (age, gender, diabetes mellitus, smoking, and hypertension) in patients with PAD involving three different anatomic areas (aortoiliac, femoropopliteal, and infrapopliteal). Multivariate analysis was performed to identify associations between atherosclerosis risk factors and PAD distribution. Results The mean age of the 476 patients was 69 years, 249 (52%) were men, and 273 (57%) had diabetes. Seventy-four percent (353) had minor tissue loss. Multivariate analysis identified three risk factors associated with PAD anatomical distribution (gender, smoking, and DM). Women had a 2.7 (CI: 1.75-4.26) times greater chance of having femoropopliteal disease. Smokers had a 3.6-fold (CI: 1.54-8.30) greater risk of aortoiliac disease. Diabetic patients were 1.8 (CI: 1.04-3.19) times more likely to have isolated infrapopliteal occlusive disease. Conclusions The study showed that gender, DM, and smoking impact on the anatomical distribution of PAD in patients with CLTI. Diabetic patients were more likely to have only infrapopliteal disease, women had a greater risk of femoropopliteal PAD, and smokers had a greater risk of aortoiliac occlusive disease.

Abstract
Diabetes-related foot disease (DFD) is a widely feared complication among people who live with diabetes. In Australia and globally, rates of disability, cardio-vascular disease, lower extremity amputation, and mortality are significantly increased in patients with DFD. In order to understand and prevent these outcomes, we analyse the common pathogenetic processes of neuropathy, arterial disease, and infection. The review then summarises important management considerations through the interdisciplinary lens. Using Australian and international guidelines, we offer a stepwise, evidence-based practical approach to the care of patients with DFD.

Severe inframalleolar disease is an independent predictor of adverse limb outcomes after endovascular revascularization in chronic limb-threatening ischemia. J Vasc Surg 2023; 77:858-863. [PMID: 36332807 DOI: 10.1016/j.jvs.2022.10.042] [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: 08/22/2022] [Revised: 10/14/2022] [Accepted: 10/19/2022] [Indexed: 11/05/2022]
Abstract
OBJECTIVE In the present study, we evaluated the effects of inframalleolar (IM) disease on the occurrence of major adverse limb events (MALE) in patients undergoing endovascular revascularization for chronic limb-threatening ischemia (CLTI). METHODS Patients who had undergone endovascular revascularization for CLTI between January 2015 and December 2019 at two university-affiliated hospitals were reviewed retrospectively. Patients with severe IM disease (pedal score of 2) were compared with those with mild to moderate IM disease (score of 0 or 1) using the Global Vascular Guidelines. The primary outcome was MALE (open revascularization, acute leg ischemia, major amputation). The secondary outcomes were mortality, reintervention, major adverse cardiac events, and perioperative complications ≤30 days after endovascular revascularization, primary limb-based patency, and the occurrence of any limb event (defined as any amputation, acute leg ischemia, or open revascularization). Kaplan-Meier estimates were used to compare the primary outcome, and the Cox proportion hazard model was used to assess the effects of IM disease. RESULTS The study included 167 limbs in 149 patients (36% female; mean age, 74 ± 12 years). Severe IM disease was identified in 71 limbs (43%). No differences were found in the baseline characteristics, except for a higher prevalence of dyslipidemia in the patients with severe IM disease (66% vs 43%; P = .003). Most patients in both groups had had a WIfI (Wound, Ischemia, foot Infection) score of 4 (severe IM disease, 64%; vs mild to moderate IM disease, 57%; P = .462) and GLASS (global limb anatomic severity scale) III anatomy (severe IM disease, 54%; vs mild to moderate IM disease, 48%; P = .752). The Kaplan-Meier estimates showed that severe IM disease was associated with lower freedom from MALE (69% vs 82%; P = .026). The Cox proportion hazard regression model showed that severe IM disease was an independent predictor of increased MALE and amputation risk (hazard ratio, 1.715; 95% confidence interval, 1.015-2.896; P = .044) after adjusting for covariates. During follow-up, patients with severe IM disease had had mortality (27% vs 31%; P = .567) and reintervention (42% vs 38%; P = .608) similar to those for patients with mild to moderate IM disease. Primary limb-based patency was also similar (79% vs 84%; P = .593) at a mean follow-up of 3.8 ± 0.8 years. CONCLUSIONS Severe IM disease was prevalent in 43% of limbs that had undergone endovascular revascularization for CLTI and was associated with lower freedom from MALE. Severe IM disease also independently increased the hazard of adverse limb outcomes and amputations in patients with CLTI by >70%, highlighting its importance as a measure of foot perfusion.

Abstract
OBJECTIVE The aim: To determine the effect of compression on the venous and arterial velocity of the main blood flow of the lower limb and the skin microcirculation of the rear part of the foot. PATIENTS AND METHODS Materials and methods: 20 healthy subjects participated in this study: 11 men 11 (55%) men and 9 (45%) girls. The ankle brachial index (ABI), femoropop¬liteal index, femoral arterial blood flow velocity (AFV), venous blood flow velocity (VFV), transcutaneous oxygen pressure (tcPO2) and carbon dioxide pressure (tcPCO2) were measured. After the general measurements were taken, the tire was inflated to 10 mm Hg under general basic conditions and kept for three minutes. The experiment ended when no decrease in tcPO2 was observed between two consecutive pressure levels. RESULTS Results: The average tire pressure to reach physiological zero was 80 mm Hg. for all participants. At 10 mmHg significant changes in indicators were found by 19% (p=0.0001). tcPCO2 values increased significantly at 10 mmHg (p=0.0319) and continued to increase until the end of the study. It was established that its values increased by 14% compared to the input data (p=0.0005). CONCLUSION Conclusions: At the maximum compression of 60 mmHg the arterial blood flow rate decreased by 5.5 times (p=0.0001). TcPCO2 increases significantly when compressed by 10 mm Hg also in parallel with the decrease in the regional perfusion index, which begins at an external compression of 40 mm Hg, which is evidence of the deterioration of the perfusion of the skin of the anterior part of the foot in healthy subjects.

Abstract
Objective. To study the impact of compression on velocity of venous and arterial main blood flow of the lower extremity, as well as cutaneous microcirculation in the back part of the foot in healthy individuals and patients with decompensated forms of varicose disease and postthrombophlebitis syndrome.
Materials and methods. In the investigation 56 individuals took part and divided into three groups: Group I – 20 healthy persons; Group II – 15 patients with varicose disease in decompensated stage; Group III– 21 patients with decompensated stage of postthrombophlebitis syndrome.
In all participants of the investigation the index of ankle–brachial pressure, deep–femoro–popliteal index, the regional perfusion index, transcutaneous partial pressure of oxygen and partial pressure of carbon dioxide, the arterial blood flow velocity in femoral artery and of venous blood flow distally from sapheno–femoral junction were measured before and after application of elastic medical knitwear of various Class of compression or the cuff pressure.
Results. In the Class III compression in patients of Group III the transcutaneously registered indices crossing have occurred between partial pressure of oxygen and carbon dioxide, accompanied by domination of the carbon dioxide partial pressure over the oxygen partial pressure while further enhancement of the compression Class. In patients of Group II this tendency was observed while application of Class IV compression only. At the investigation beginning the values of partial pressure of carbon dioxide registered were higher in the Group III patients, than in the patients of Group II (p=0.0001).
Conclusion. While application of the Class III compression the velocity of the hip venous blood flow, comparing with its initial values, have lowered at average by 78% in patients of Group II and at average in 7.4 times in the patients of |Group III (p=0.0001). It is affordable in patients, suffering decompensated postthrombophlebitic syndrome, to apply the elastic compression of Classes I–II, while in those, having varicose disease in decompensated stage, – the elastic compression of Classes III and iV as well.

Abstract
Peripheral arterialdisease (PAD) can result in diabetic foot ulcers, gangrene, and even amputation. Since most cases of PAD in diabetic patients are associated with peripheral neuropathy, the symptoms of vascular disease are easily concealed by the symptoms of neuropathy and are ignored by people, so it is critical for health care providers to screen PAD for the diabetes patients. This study was carried out to identify theprevalence and related factors of PAD in diabetes mellitus inpatients. This was a cross-sectional observational study. A total of 855 patients were enrolled in the study from December 2018 to December 2019. The patients were divided into a non-PAD group (ABI = 0.9-1.3) and a PAD group (ABI <0.9). Logistic multivariate regression analysis showed that age, LDL-C, dorsalis pedis artery pulsation (left foot), and sensory-current threshold (right foot) were related factors for peripheral arterial disease. Patients who are older and have a higher LDL-C level, abnormal dorsal foot pulse, and abnormal sensory-current threshold must be vigilant, and receive early screening for PAD diagnosis and treatment to avoid a malignant outcome. In clinical work, medical staff should actively apply PAD screening to diabetic patients, identify risk factors as early as possible, conduct early interventions, reduce the risk of PAD in patients, and avoid the occurrence of adverse outcomes.

Abstract
INTRODUCTION There is currently no universal and uniform pattern of peripheral arterial disease (PAD) in the lower limbs; however, it is influenced by various cardiovascular factors of the individual. The objective of this study was to identify the arteriographic patterns of PAD in the lower limbs according to cardiovascular factors in a Peruvian cohort of patients. METHODS This is an analytical, observational, and retrospective study. The arteriographic patterns of PAD in the aortoiliac segment were analyzed with the TransAtlantic InterSociety Consensus (TASC-II) score and the Global Anatomic Staging System (GLASS) for the femoropopliteal (FP), infraopopliteal (IP), and pedial (P) segments in a Peruvian cohort from January 2018 to May 2021. RESULTS 595 patients (833 extremities) were analyzed with a mean age of 67.54 ± 16.39 years, and the main cardiovascular factor was diabetes (65.04%). The patients older than 65 years with GLASS FP 4 (p = 0.042), IP 0 (p = 0.004), and P2 (p = 0.047) presented significant findings: in men and women with GLASS IP 4 (p = 0.031) and P 2 (p = 0.045); diabetes with TASC-II A (p = 0.031), GLASS FP 4 (p = 0.038), IP 4 (p = 0.009), and P2 (p = 0.003); dyslipidemia with TASC-II D (p = 0.027), GLASS FP 4 (p = 0.038), IP 0 (p = 0.009), and P0 (p = 0.003); smoking with TASC-II D (p = 0.001), GLASS FP 4 (p = 0.049) and IP 0 (p = 0.008); chronic coronary disease with GLASS IP 4 (p = 0.049) and P2 (p = 0.037); chronic kidney disease with GLASS FP 4 (p=0.047), IP 4 (p = 0.004), and P2 (p = 0.016); and previous amputation history with GLASS IP 4 (p = 0.015) and P2 (p = 0.039). The most frequent arteriographic pattern of PAD in the lower limbs of our cohort was TASC-II A, GLASS FP 0 and 4, IP 0, and P2 (p = 0.047). CONCLUSION Our work will allow the limb salvage teams to understand the behavior of PAD affectation in the population of our environment, allowing a timely control of cardiovascular risk factors, adequate revascularization planning, and a significant reduction in the risk of loss of limb.

Abstract
The instep flap and medialis pedis flap are both originate based on the medial plantar artery. The medialis pedis flap is based from the deep branch and the instep flap is based from the superficial branch. To increase the axial rotation, it is acceptable to ligate the lateral plantar artery. However, this can partially affect the blood supply of the plantar metatarsal arch. We restored the blood flow with a vein graft between the posterior tibial artery and the ligated stump. From 2012 to 2020, 12 cases of heel reconstruction, including seven instep flaps and five medialis pedis flaps, were performed with ligation of the lateral plantar artery. The stump of the lateral plantar artery was restored with a vein graft and between the posterior tibial artery and the ligated stump. Patients were followed for 18 months. Long-term results showed the vascular restoration of the lateral plantar artery remained patent demonstrated by doppler ultrasonography. Restoring blood flow to the lateral plantar artery maintains good blood supply to the toes. If the patient in the future develops a chronic degenerative disease, with microvascular complications, bypass surgery can still be performed because of the patency of both branches.

Abstract
BACKGROUND Patients with diabetes are at increased risk of developing chronic limb-threatening ischemia (CLTI) due to peripheral arterial disease, and this often results in lower extremity amputation (LEA). Little is known of the interaction between diabetes and other vascular risk factors in affecting the risk of CLTI. METHODS We investigated the association of diabetes, and its interaction with hypertension, body mass index (BMI) and smoking, with the risk of LEA due to CLTI in the population-based Singapore Chinese Health Study. Participants were interviewed at recruitment (1993-1998) and 656 incident LEA cases were identified via linkage with nationwide hospital database through 2017. Multivariate-adjusted Cox proportional hazards models were used to compute hazard ratios (HRs) and 95% CIs for the associations. RESULTS The HR (95% CI) for LEA risk was 13.41 (11.38-15.79) in participants with diabetes compared to their counterparts without diabetes, and the risk increased in a stepwise manner with duration of diabetes (P for trend < 0.0001). Hypertension and increased BMI independently increased LEA risk in those without diabetes but did not increase the risk in those with diabetes (P for interaction with diabetes ≤ 0.0006). Conversely, current smoking conferred a risk increment of about 40% regardless of diabetes status. CONCLUSIONS Although diabetes conferred more than tenfold increase in risk of LEA, hypertension and increased BMI did not further increase LEA risk among those with diabetes, suggesting a common mechanistic pathway for these risk factors. In contrast, smoking may act via an alternative pathway and thus confer additional risk regardless of diabetes status.

Impact of Tibial Bypass Conduit on Long-Term Amputation-Free Survival and Primary Patency in the Vascular Quality Initiative. J Vasc Surg 2021; 75:1351-1357.e2.

Abstract
BACKGROUND Much research remains focused on tibial bypass conduit selection. We sought to describe long-term amputation-free survival (AFS) and primary patency (PP) of patients undergoing tibial bypass by conduit type and configuration across several permutations in the Society for Vascular Surgery (SVS) Vascular Quality Initiative (VQI). METHODS Patients in the VQI registry undergoing elective first-time femoral- or popliteal-to-tibial bypass for occlusive disease involving rest pain or tissue loss were identified. Prior ipsilateral infrainguinal bypass or concomitant procedures were excluded. Outcomes of interest included patient AFS at 22 months and PP at 1 year (defined as freedom from revision, thrombectomy, or graft occlusion). RESULTS A total of 4,192 bypasses were identified. The majority utilized Great Saphenous Vein (GSV) (76.2%), followed by polytetrafluoroethylene (PTFE) (10.6%), non-autologous biologic (NABC) (6.5%), composite (3.3%), arm vein (2.8%), and Small Saphenous Vein (SSV) (0.6%). Compared to all prosthetic and composite bypasses, vein grafts had the best AFS (76.4%, p<0.0001) and PP (68.1%, p=0.041). Of the single segment vein conduits, GSV bypasses had the best PP (69.1%) and arm vein the worst (60.2%). AFS and PP were similar between single segment GSV orientations. Single segment GSV bypasses exhibited better PP than multiple segment bypasses (69.1% vs 54.6%, p=0.0016). PP was significantly better for PTFE compared to NABC (68.4% vs 51.2%, p=0.0039). PP did not significantly differ between vein cuff (PWC) for prosthetic bypass compared to no vein cuff (PNC) (69.1% vs 59.7%, p=0.091). PP was not significantly different between single segment GSV and prosthetic grafts with vein cuff (69.1% vs 69.1%, p=0.51). There were no significant differences in AFS comparing arm vein, PWC, or composite grafts (67.2% vs 63.8% vs 59.3%, p=0.092), as well as in PP (60.2% vs 69.1% vs 54.8%, p=0.14). CONCLUSIONS Single-segment vein bypass was only marginally the most optimal conduit. Surprisingly, there may be more equipoise among conduit types, particularly in the absence of adequate GSV. Prosthetic grafts overall may not be as disadvantaged in the long term as initially thought, especially when compared to arm vein, as PWC did not significantly differ in primary patency. Similarly, a composite conduit may not impact long-term outcomes. These data suggest that conduit choice may not impact outcomes to the degree previously thought and that other factors may have a greater impact than presumed, especially in conduit limited situations.

Abstract
The ankle-brachial index (ABI) is the relationship between the systolic blood pressure taken at the ankle level and the brachial artery. A pathological ABI (<0.90 or >1.40) indicates the presence of peripheral artery disease (PAD). Many studies indicate the great utility of this test in the diagnosis of PAD due to its ease of use, reproducibility, low cost, and high cost-effectiveness. This evaluation can be directly correlated with cardiovascular morbidity and mortality; however, it has recently been confirmed that a low ABI can be a predictor of major cardiovascular events, as it is related to diabetes mellitus, chronic coronary disease, stroke, and more. The objective of this work was to review the current evidence on the importance of ABI in the diagnosis of PAD and its main role as a predictor of cardiovascular morbidity and mortality.

Abstract
Chronic limb-threatening ischemia (CLTI) is the most severe form of peripheral artery disease. It is estimated that 60% of all nontraumatic lower-extremity amputations performed annually in the United States are in patients with diabetes and CLTI. The consequences of this condition are extraordinary, with substantial patient morbidity and mortality and high socioeconomic costs. Strategies that optimize the success of arterial revascularization in this unique patient population can have a substantial public health impact and improve patient outcomes. This article provides an up-to-date comprehensive assessment of management strategies for patients afflicted by both diabetes and CLTI.

Abstract
This study aimed to examine the distribution of lower limb atherosclerotic lesions in a multi-ethnic Asian cohort with chronic limb threatening ischemia (CLTI) from Singapore. The Society for Vascular Surgery Vascular Quality Initiative registry database was used to identify 265 CLTI patients who underwent percutaneous angioplasty between June 2019 and December 2019, of whom 171 (64.5%) were male, and the mean age was 67.9±11.0 years. The majority were diabetic (84.5%) and 145 (54.7%) had chronic kidney disease (CKD). The majority of the lower limb atherosclerotic lesions were de novo lesions (598/797, 75.0%), predominantly TransAtlantic Inter-Society Consensus II C/D (451/797, 56.6%), and were moderately to severely calcified (76.3%). The anterior tibial artery and femoral-popliteal artery were the most commonly affected vessels. The mean length of the treated lesions was 14.5±13.7 cm. There was a tendency, albeit insignificant, of multi-level disease in those who were diabetic or had CKD.

Abstract
BACKGROUND The aim of MERLION (NCT04073121) was to evaluate the outcomes of the mono or combination therapy of the iVascular LuminorTM drug coated balloon (DCB) and AngioliteTM drug eluting stent for treatment of TASC II C/D tibial occlusive lesions in Asian patients presenting with chronic limb threatening ischemia (CLTI) from Singapore. METHODS MERLION was a prospective, non-randomized, single arm, observational, multicenter clinical study. Complication-free survival at one month was the safety endpoint. Immediate technical success, 12-month primary vessel patency, limb salvage, freedom from target lesion revascularization (TLR) and amputation free survival (AFS) were the efficacy endpoints of interest. RESULTS 50 patients were included. There were 32 males (64% males; mean age 66.4±8.9 years). Majority were Rutherford 5 severity (41/50; 82%). Co-morbidities included diabetes mellitus (47/50; 94.0%), end-stage renal failure (25/50; 50.0%), and hypertension (44/50; 88%). 66 atherosclerotic lesions were treated (47 de novo and 19 restenotic; 60.6% TASC C and 39.4% TASC D). Mean lesion length treated was 13.7±9.5cm. There was 100% technical success. There were 3/66 (4.5%) bailout stenting for severe flow limiting dissections. 12-month primary tibial patency was 34/49 (69.4%) and freedom from TLR was 40/49 (81.5%). AFS was 74.0% (37/50). At 12 months, mean Rutherford scores improved from 100% (Rutherford score>3) at baseline to 31% at 12 months (p<0.05) and wound healing rate was 65.7%. CONCLUSIONS The iVascular LuminorTM DCB is safe and efficacious in treating highly complex infra-popliteal atherosclerotic lesions in an otherwise challenging frail population of CLTI patients from Singapore.

Abstract
INTRODUCTION The increasing prevalence of diabetes mellitus and advances in endovascular therapies continue to have an impact on the epidemiology and management of lower extremity arterial disease. This study describes trends in lower extremity revascularisation and major lower limb amputation in NHS England over the past two decades (2000-2019). METHODS Numbers of lower extremity endovascular interventions, open surgical procedures and major lower limb amputations performed in NHS England between 2000 and 2019 were extracted from publicly available hospital admitted patient care activity reports. Trends in intervention were assessed with linear regression models and chi-square tests for trend. RESULTS Over this period, 527,131 revascularisations and 92,053 amputations were performed. The mean age of patients was 67.5 years (standard deviation 1.6 years) and 65.3% were male. The number of lower limb revascularisation procedures increased by 402.4 units/year (95% confidence interval, CI, 290.1-514.6, p < 0.001). The number of endovascular interventions rose by 43.5% (10,912 in 2000 vs 15,657 in 2019; β = 359.5.0, 95% CI 279.3-439.8, p < 0.001) compared with no significant increase in the number of open surgical procedures (8,483 in 2000 vs 7,872 in 2019; β = 42.8, 95% CI -8.3 to 94.0, p = 0.095). The number of major lower limb amputations has decreased by 9.4% (5,418 in 2000 vs 4,907 in 2019; β = -31.0; 95% CI -49.6 to -12.5, R2 = 0.42, p = 0.003). CONCLUSIONS There has been a significant increase in the rate of lower limb revascularisation procedures associated with decreased numbers of major lower limb amputations over the past two decades. These changes in overall trends may affect both service provision and vascular surgery training planning.

Abstract
Objectives Peripheral artery disease is estimated to affect 237 million individuals worldwide. Critical limb ischaemia, also known as chronic limb threatening ischaemia is a consequence of the progression of peripheral artery disease which occurs in ∼21% of patients over a five-year period. The aim of this systematic review is to assess the use of additional below-the-ankle angioplasty in comparison to the use of above-the-ankle angioplasty alone, and the subsequent rates of amputation, wound healing, restenosis, rest pain, reintervention and complications. Methods This systematic review was undertaken in accordance with PRISMA guidelines following a registered protocol (CRD42019154893). Online databases were searched using a search strategy of 20 keywords. Included articles reported the outcome for inframalleolar (pedal artery, pedal arch, plantar arteries) angioplasty with additional proximal angioplasty in comparison to proximal angioplasty alone. GRADE assessment was applied to assess the quality of the evidence. Results After screening 1089 articles, 10 articles met the inclusion criteria. Comparative performance assessment of below-the-ankle with above-the-ankle versus above-the-ankle angioplasty alone was undertaken in 3 articles, with the remaining 7 articles reporting outcomes of below-the-ankle with above-the-ankle angioplasty with no distinct comparator group. Significant decrease in major lower limb amputation at the last follow-up in the below-the-ankle group when compared with the above-the-ankle angioplasty alone group was observed in a single study (3.45% vs. 14.9%, p < 0.05). Improved wound healing rate at follow-up in the below-the-ankle group versus above-the-ankle angioplasty alone group was also reported in a single study (59.3% vs. 38.1%, p < 0.05). Subsequent rate of amputation after below-the-ankle angioplasty has been estimated as 23.5%. Conclusion To date, there is a lack of studies assessing inframalleolar interventions and their use in improving limb salvage, wound healing and symptomatology. Prospective RCTs should be undertaken with adequate participant numbers to be sufficiently powered and report clinically important end-points.

Abstract
Background: Acute lower limb ischaemia (ALI) is a life and limb threatening vascular emergency. Acute compartment syndrome (ACS) may develop upon revascularization. The risk of fasciotomy was hypothesized to be decreased in women due to their lower calf muscle mass. The main aim was to evaluate risk factors for fasciotomy after revascularization for ALI. Methods: This is a retrospective observational study of patients undergoing revascularization for ALI between 2001 and 2018. Factors associated with outcome at 1 year in univariable analysis (p < 0.1) were chosen for multi-variable analysis and expressed in Odds Ratios (OR) with 95% confidence intervals (CI). Results: The median age for women (n = 394) was 75 years and men (n = 449) was 70 years (p < 0.001). The frequency of fasciotomy was 10.0% (84/843). The median in-hospital stay was 28 vs. 6 days for patients undergoing fasciotomy and not, respectively (p < 0.001). In adjusted analysis, renal insufficiency (OR 1.77, 95% CI 1.04–3.01), motor deficit (OR 4.40, 95% CI 2.45–7.92), popliteal artery aneurysm thromboembolism (OR 2.26, 95% CI 1.06–4.80), and open vascular surgery (OR 3.43, 95% CI 1.97–5.98) were associated with an increased risk of fasciotomy. Female patients (OR 0.49, 95% CI 0.28–0.84) and anemia (OR 0.52, 95% CI 0.28–0.84) had a lower risk. The major amputation/mortality rate at 1-year was 27.7%; fasciotomy (OR 1.94, 95% CI 1.11–3.40), anemia (OR 1.84, 95% CI 1.24–2.73) and female gender (OR 1.44, 95% CI 1.00–2.08) were independently associated with an increased risk. Conclusions: Female patients had lower rates of fasciotomies, but subsequent higher risk of major amputation/mortality, which may be attributed to inferior results of revascularization. Lower muscle mass and underdiagnosis of ACS could also explain the lower frequency of fasciotomy for female patients. Further studies are needed to better understand gender differences in presentation of ALI, revascularization results and diagnosis of ACS.

High TG to HDL ratio plays a significant role on atherosclerosis extension in prediabetes and newly diagnosed type 2 diabetes subjects. Diabetes Metab Res Rev 2021; 37:e3367.

Abstract
AIMS We investigated the role of TG to HDL ratio (TG/HDL) on atherosclerosis extension, defined as presence of coronary artery calcium (CAC), carotid and femoral plaque, in prediabetes or newly diagnosed type 2 diabetes (T2D). METHODS We performed a retrospective, cross-sectional, single centre study involving 440 prediabetes or newly diagnosed controlled T2D subjects. Participants underwent CAC analysis by computed tomography and carotid and femoral plaque evaluation by ultrasonography and were stratified in high TG/HDL (H-TG/HDL) or low TG/HDL (L-TG/HDL) group according to TG/HDL median value. We estimated atherosclerosis extension according to the number of involved vascular districts. RESULTS CAC was higher in the H-TG/HDL group than L-TG/HDL group (29.15 [0.0-95.68] vs 0.0 [0.0-53.97] AU, P < .01) and CAC > 0 was more prevalent in the H-TG/HDL group than L-TG/HDL group (64.5% vs 45%, P < .001). Femoral atherosclerosis was higher in the H-TG/HDL group than L-TG/HDL group (57.3% vs 43.6%, P < .01). H-TG/HDL group exhibited a lower prevalence of subjects with 0-TWP compared to L-TG/HDL group (21.8% vs 38.6%, P < .01) and higher percentages of subjects with 2-TWP or 3-TWP than L-TG/HDL group (for 2-TWP 29.5% vs 21.5%, P < .05; for 3-TWP 32.7% vs 20.9%, P < .01). Multiple logistic regression analysis showed that a H-TG/HDL was inversely associated to 0-TWP (P < .05) and positively associated with 2-TWP (P < .05) and 3-TWP (P < .01). CONCLUSIONS Our data suggest that TG/HDL is a marker of increased atherosclerotic extension in prediabetes and newly diagnosed T2D and may be useful to identify subjects with a higher cardiovascular risk profile.

An Extension of the Bollinger Scoring System to Analyse the Distribution of Macrovascular Disease of the Lower Limb in Diabetes. Eur J Vasc Endovasc Surg 2020; 61:280-286. [PMID: 33309168 DOI: 10.1016/j.ejvs.2020.11.017] [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: 06/22/2020] [Revised: 10/16/2020] [Accepted: 11/06/2020] [Indexed: 11/21/2022]
Abstract
OBJECTIVE While it is generally considered that patients with diabetes mellitus (DM) have more distal peripheral arterial disease (PAD), there is little information on how individual vessels are affected. The aim of this study was to adapt Bollinger's scoring system for lower limb angiograms (DSAs) to include the distal and planter vessels. The reliability of this extension was tested and was used to compare the distribution of disease in two cohorts of patients with and without DM. METHODS Patients who had undergone DSA ± angioplasty for PAD at a single centre between September 2010 and April 2014 were identified. Twenty-five patients' images were reviewed by four clinicians and scored using an extended version of the Bollinger score. A total of 153 patients with DM were matched, for age, sex, ethnicity, smoking, and hypertension, with 153 patients without DM. The infrainguinal vessels were divided into 16 arterial segments, including plantar vessels, and scored using the Bollinger score. The score ranges from 0 to 15. Fifteen represents an arterial segment with more than 50% of its length occluded. Interobserver reliability was tested using interclass correlation (ICC) and Cohen's kappa coefficient. RESULTS The ICC demonstrated good agreement between observers (0.76 [0.72-0.79]) with good internal consistency (Cronbach's alpha 0.93). When the Bollinger scores were categorised, the results were weaker, Cohen's kappa ranged from 0.39 (standard error 0.033) to 0.54 (0.030). Patients with DM had a higher burden of disease in the anterior tibial and posterior tibial arteries with relative sparing of the peroneal artery and no difference in the plantar vessels. CONCLUSION It has been demonstrated that the Bollinger score can be extended to include the distal vessels. This amended scoring system can be used to compare the burden of distal disease in patients with PAD. How the score relates to clinical presentation and outcomes needs further investigation.

Abstract
Objectives: To prospectively compare three image acquisition techniques in lower extremity CT angiography: the “standard” anterograde technique (SA), the adaptive anterograde technique (AA), and the retrograde acquisition technique (RA). Materials and Methods: Sixty consecutive patients were prospectively enrolled and randomized into three acquisition groups: 20 patients were evaluated with SA, 20 with AA as described by Qanadli et al., and 20 with caudocranial acquisition from the feet to the abdominal aorta (RA). Quantitative image quality was assessed by measuring the intraluminal attenuation at different levels of interest, with a total of 536 levels. Qualitative image quality was assessed by two radiologists in consensus using a Likert scale to rate the arterial enhancement and venous return. For each patient and limb, the presence of occlusive or aneurysmal disease was documented. Results: In quantitative analysis, RA showed lower attenuation values than SA and AA (p < 0.01). AA showed the highest and most homogeneous attenuation along the arterial tree. In qualitative analysis, AA had the lowest rate of non-diagnostic vascular segments (3.9%) compared to SA and RA (4.7 and 13.1%, respectively, p < 0.01). The influence of venous return was significantly different among the different techniques; venous contamination was particularly prevalent at the aortic level with RA (9.4% of patients, 0% with SA and AA, p < 0.01). The presence of stenosis or occlusion had no significant influence on the attenuation values across all levels and acquisition techniques. Conversely, the presence of aneurysmal disease had a significant effect on the luminal attenuation in AA (higher attenuation) and RA (lower attenuation) at the iliac (p = 0.03 and 0.04, respectively) and femoral levels (p = 0.02 and <0.01, respectively). Conclusion: Considering both quantitative and qualitative analysis, AA performed better than SA and RA, providing the highest percentage of optimal vascular enhancement. AA should be recommended as the technique of choice, specifically in the presence of aneurysmal disease. Alternatively, SA can be useful in case of renal failure, as the test bolus is unnecessary. Finally, the increasing availability of fast CT systems will likely overcome the limitations of RA.

Abstract
Background The ankle-brachial index (ABI) is widely used for determining the presence and severity of peripheral arterial disease (PAD), and current guidelines suggest it should be used to monitor possible progression in affected individuals. It is therefore important that the technique demonstrates adequate reliability for repeated measurements. Existing studies suggest that the ABI is reliable in the general population however, there is a lack of evidence for the reliability of the ABI in people with diabetes. The aim of this study was to investigate the intra-tester reliability of the ABI in people with and without diabetes. Methods Eighty-five participants (40 with and 45 without diabetes) underwent ankle and brachial systolic blood pressure measurements by a single clinician during two testing sessions. Intraclass correlation coefficients (ICC), their 95% limits of agreement, standard error of measurement and minimal detectable change were determined. Results Intra-tester reliability of the ABI was found to be good (ICC: 0.80), however sub-group analysis of participants with and without diabetes found that ABI was slightly less reliable in people with diabetes (ICC: 0.78) than in those without (ICC: 0.82). The relatively large limits of agreement (− 0.16 to 0.16), standard error of measurement (0.03 overall, 0.04 for the diabetes group), and minimal detectable change (0.08 overall, 0.11 for the diabetes group) suggest that a large change in ABI is required for it to demonstrate a true change rather than the result of measurement variability. The minimal detectable change for the ABI was 0.08 overall, and 0.11 for the diabetes group. Conclusions The ABI demonstrated good reliability in all groups analysed. However, the wide limits of agreement and considerable standard error of measurement obtained support the use of multiple methods of vascular assessment for ongoing monitoring of lower limb vascular status.

Abstract
Peripheral arterial disease is a result of atheroma. This disease is frequent in subjects with vascular risk factors. This disease is also frequent in low income countries. The detection and the diagnosis of peripheral arterial disease is obtained by calculating the ankle brachial index. Patients with peripheral arterial disease are not always symptomatic thus explaining how this disease is under diagnosed. The symptoms can be absent, and especially in case of diabetes or in women. In case of peripheral arterial disease, atheroma often involves other arterial vascular networks especially the coronaries. An adapted treatment reduces the morbi-mortality linked to this disease. This treatment is based on the correction of the vascular risk factors and especially tobacco cessation, walking rehabilitation and drugs (antiplatelet agent, statin, renin angiotensin system blocker). In case of rest or critic ischemia, the first-line treatment is a revascularisation. In peripheral arterial disease, management of patients is often non optimal and therapeutic targets fairly often obtained.

Objectives To evaluate skeletal muscle mass in patients with both type 2 diabetes mellitus (T2DM) and concomitant lower extremity arterial disease (LEAD) and determine the contribution of skeletal muscle mass to macrovascular diseases. Methods In total, 112 patients with T2DM were divided into the T2DM and T2DM + LEAD groups. Hepatic function, renal function, uric acid, blood glucose, and glycated hemoglobin (HbA1C) were measured. Dual-energy X-ray absorptiometry was used to measure visceral fat area and skeletal muscle mass index (SMI). Results Waist-to-hip ratio, uric acid, and body fat percentage were significantly higher in the T2DM+LEAD group than in the T2DM group; SMI was significantly lower in the T2DM+LEAD group than in the T2DM group. There were no significant differences in albumin, creatinine, fasting blood glucose, HbA1C, or blood lipids. Uric acid, SMI, and body fat percentage were significantly positively correlated with T2DM and concomitant LEAD. Logistic regression analyses suggested that SMI is an independent risk factor for LEAD in T2DM (odds ratio = 1.517; 95% confidence interval: 1.082–2.126). Conclusions Skeletal muscle mass is lower in patients with T2DM and concomitant LEAD than in patients with T2DM who do not exhibit LEAD. SMI is an important risk factor for LEAD.

Abstract
BACKGROUND Abnormalities in glucose metabolism are common in patients with arterial disease. Chronic hyperglycemia and insulin resistance contribute to the complexity of vascular disorders. They also overlap with the effects of perioperative hyperglycemia on adverse perioperative outcomes. We provide an overview of the pathophysiologic consequences of dysglycemia and the evidence behind glycemic control in patients undergoing vascular surgery. METHODS We searched the literature for major studies evaluating the pathophysiology of hyperglycemia in microvascular and macrovascular beds, randomized trials in perioperative populations, and meta-analyses. The literature was summarized to guide therapy in the population of vascular patients and for the perioperative period. RESULTS National standards for glycemic control after vascular interventions were not identified. Mounting evidence exists for the long-term consequences of poor glycemic control on the progression of vascular disease. Similarly, there is a large body of evidence supporting tight control of hyperglycemia after general and cardiac surgery during the critical perioperative period. The absolute glucose target remains controversial. Randomized controlled studies are lacking in vascular surgery patients, but the current evidence can be extrapolated to guide management after vascular interventions. Glycated hemoglobin is a biomarker for increased mortality and vascular morbidity after vascular surgery. CONCLUSIONS Hyperglycemia contributes to poor outcome in the vascular patient. Further vascular focused studies are required to determine the proper perioperative serum glucose target and the long-term glycated hemoglobin range.

Abstract
BACKGROUND AND AIMS Atherogenic index of plasma (AIP), defined as the logarithm of triglycerides to high-density lipoprotein cholesterol (HDL-C) ratio, is a strong predictor of future cardiovascular disease. Our aim was to examine the association of AIP with haemodynamic variables in normotensive and never-treated hypertensive subjects in a cross-sectional study. METHODS Supine haemodynamics in 615 subjects without antihypertensive and lipid-lowering medications were examined using whole-body impedance cardiography and radial pulse wave analysis. Linear regression analysis was applied to investigate the association of AIP with haemodynamic variables and age, sex, body mass index (BMI), smoking status, alcohol consumption, plasma C-reactive protein, electrolytes, uric acid, low density lipoprotein cholesterol (LDL-C), estimated glomerular filtration rate, and quantitative insulin sensitivity check index. RESULTS The demographics and laboratory values of the study population were (mean ± 95% confidence interval): age 44.9 ± 1.0 years, BMI 26.8 ± 0.4 kg/m2, office blood pressure 140.6 ± 1.6/89.4 ± 1.0 mmHg, total cholesterol 5.2 ± 0.08, LDL-C 3.1 ± 0.08, triglycerides 1.2 ± 0.08, HDL-C 1.6 ± 0.04 mmol/l, and AIP -0.15 ± 0.02. Age (standardized coefficient Beta 0.508, p < .001) and aortic systolic blood pressure (Beta 0.239, p < .001) presented with the strongest associations with pulse wave velocity. However, AIP was also associated with pulse wave velocity (Beta 0.145, p < .001). AIP was not related with aortic or radial blood pressure, cardiac output, systemic vascular resistance, or augmentation index. CONCLUSIONS AIP is directly and independently associated with arterial stiffness, a variable strongly related to cardiovascular risk. This supports more widespread use of AIP in standard clinical cardiovascular disease risk evaluation.

Abstract
This review considers peripheral arterial disease (PAD) in the diabetic ischaemic lower limb including both macrovascular and microvascular aspects. The presentation of PAD is probably not significantly different in type 1 compared with type 2 diabetes. PAD in diabetic patients is diffuse and located distally being most severe in the crural and also the foot arteries. It is associated with arterial calcification and occlusion of the arteries rather than stenosis. Compared with the nondiabetic patient, PAD develops at a younger age, and women are equally affected as men. It is not known whether the presentation of ischaemic lower limb disease in diabetes can be explained by one disease, namely, atherosclerosis, which has particular features peculiar to diabetes such as distal arterial involvement, or by the occurrence of two separate diseases: first, classical atherosclerosis and, second, a diabetic macroangiopathy, a term for nonatherosclerotic arterial disease in diabetes that is characterized by medial arterial calcification. Furthermore, there is controversy with regard to the significance of structural changes in the microcirculation of the diabetic foot.

Abstract
Background: Heel ulcers in patients with diabetes mellitus (DM) and peripheral arterial disease (PAD) are hard to heal. The aim of the present study was to evaluate the difference in amputation-free survival (AFS) between open and endovascular revascularization in patients with DM, PAD, and heel ulcers. Methods: Retrospective comparative study of results of open versus endovascular surgery in patients with DM, PAD, and heel ulcer presented at the multidisciplinary diabetes foot clinic between 1983 and 2013. Results: Patients with heel ulcers were treated with endovascular intervention (n = 97) and open vascular surgery (n = 30). Kaplan-Meier analysis showed that the AFS was higher in patients undergoing open vascular surgery compared to the endovascular group ( P = .009). Multivariate analysis showed that open vascular surgery versus endovascular therapy (hazard ratio 2.1, 95% confidence interval 1.1-3.9; P = .025) was an independent factor associated with higher AFS. The proportion of patients undergoing endovascular therapy in the former (1983-2000) time period was 47% compared to 89% in the latter (2001-2013) time period ( P < .001). Conclusion: The AFS was higher after open than endovascular surgery among patients with DM and PAD with heel ulcer. These results suggest that open vascular surgery should be offered more often as opposed to current practice.
