Diabetes AND lower Limb Ischaemia

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)...

OBJECTIVE: Inflammation is an early feature of acute limb ischaemia (ALI), hence the potential prognostic significance of inflammatory biomarkers. This study aimed to assess the value of pre-operative inflammatory biomarkers, specifically the neutrophil to lymphocyte ratio (NLR) and the platelet to lymphocyte ratio (PLR), for predicting an adverse outcome after revascularisation for ALI. METHODS: All patients submitted to lower limb revascularisation for Rutherford IIa or IIb ALI at the authors' institution between 2009 and 2019 were screened retrospectively...

BACKGROUND: Sarcopenia is adversely associated with survival in several diseases. Vasculopathy is often associated with multimorbidity and consequent deconditioning with poor long-term outcomes. This study examined the impact of sarcopenia on clinical outcome in patients with and without critical limb-threatening ischaemia who underwent infrainguinal bypass surgery. METHODS: All patients undergoing infra-inguinal surgical revascularisation in 2016-2018 were retrospectively reviewed...

BACKGROUND: The Vascular Research Collaborative was established to develop a national research strategy for patients with vascular disease in the UK. This project aimed to establish national research priorities in this patient group. METHODS: A modified Delphi approach, an established method for reaching a consensus opinion among a group of experts in a particular field, was used to survey national multidisciplinary vascular clinical specialists. Two rounds of online surveys were conducted involving the membership of the Vascular Society, Society of Vascular Nurses, Society for Vascular Technology, and the Rouleaux Club (vascular surgical trainees)...

Neuropathy and ischaemia are two great pathologies of the diabetic foot which lead to the characteristic features of foot ulceration (neuropathic and ischaemic) and Charcot neuroarthropathy. These can be complicated by infection and eventually may result in amputation (minor or major) and increased mortality. All of these features contribute to considerable clinical and economic burden. Peripheral nerves in the lower limbs are susceptible to different types of damage in patients with diabetes leading to distinctive syndromes...

<b/> Background : Peripheral artery disease presents an increasing healthcare burden worldwide. Day-case angioplasty in a secondary care setting can be a safe and effective means of meeting the growing demand for lower limb revascularisation. We evaluated the safety and efficacy of a day-case-based angioplasty service in a UK district general hospital. Patients and methods : Consecutive patients undergoing endovascular revascularisation between August 2018-February 2020 were analysed retrospectively. All patients were discussed at a multi-disciplinary (diabetic foot) team meeting following a day case algorithm...

OBJECTIVE: Most major lower limb amputations are related to peripheral artery disease (PAD) or diabetes. Just 40% of patients who undergo major lower limb amputation will use a prosthesis yet measures of surgical success commonly focus on prosthesis use. Patient reported outcome measures (PROMs) are valuable to comprehensively evaluate health related quality of life (HRQL) after surgery. This systematic review aimed to identify and describe PROMs available to assess HRQL in patients after amputation for PAD or diabetes...

OBJECTIVE: A stepped care model, in which patients are primarily treated with supervised exercise therapy (SET), is recommended as the optimal strategy for intermittent claudication (IC). The aim of this study was to determine the primary treatment (SET, endovascular revascularisation [ER], or open surgery) in relation to secondary lower limb revascularisation and survival in patients with IC. METHODS: This study was a nationwide retrospective data analysis of health insurance claims of patients newly diagnosed with IC between January 2013 and December 2017...

Ischaemic diabetic heel ulcers are difficult to treat and prognosis is often guarded. The aim was to document our outcome of treating heel ulcers following revascularization in a predominantly diabetic Asian cohort presenting with chronic limb threatening ischaemia from Singapore. Retrospective cohort study (n = 66, 66 limbs) over a 5-year period. Data were collected from hospital electronic health records. Outcomes included time to healing, amputation free survival (AFS), and mortality. Minimum follow-up period was 6 months...

When diabetes mellitus is not properly controlled with drugs and a healthy lifestyle, it exposes patients with advanced peripheral arterial disease or critical limb ischaemia (CLI) to the most serious complications, in particular lower limb ulcers. Surgical or endovascular treatments represent the first line of intervention; in addition, the adequate management of ulcers can guarantee not only a faster wound healing but also the improvement of the patient's prognosis. To speed up this process, negative pressure wound therapy (NPWT), platelet-rich plasma (PRP), and other advanced moist wound dressing have been proposed...

Type 2 diabetes is a prominent risk factor for peripheral artery disease (PAD). Yet, the mechanistic link between diabetes and PAD remains unclear. This study proposes that dysregulation of the endogenous hormone ghrelin, a potent modulator of vascular function, underpins the causal link between diabetes and PAD. Moreover, this study aimed to demonstrate the therapeutic potential of exogenous ghrelin in a diabetic mouse model of PAD. Standard ELISA analysis was used to quantify and compare circulating levels of ghrelin between (i) human diabetic patients with or without PAD (clinic) and (ii) db/db diabetic and non-diabetic mice (lab)...

OBJECTIVE: Although high quality epidemiological data are lacking, the global increase in chronic limb threatening ischaemia may be disproportionately affecting low and LMICs. All available data for outcomes from bypass for limb salvage are from high income countries, with none from LMIC settings where the challenge is greatest. This study aimed to assess the clinical outcomes following vein lower extremity bypass for chronic limb threatening ischaemia at the University of Colombo, Sri Lanka, and to compare patients and outcomes with those described in the Society for Vascular Surgery (SVS) Objective Performance Goals (OPG) and United States National Surgical Quality Improvement Program (NSQIP)...

Background: Left ventricular thrombus (LVT) is a complication of acute myocardial infarction (AMI) due to localised haemostasis. LVT is typically seen 3-12 days following AMI and is seldom seen within the first 24 hours. LVT increases the risk of mortality due to systemic thromboembolism. Patients with Coronavirus Disease-19 (COVID-19) are potentially hypercoagulable and this may promote early development of LVT. Case: A 50-year-old man with no past medical history was admitted with a severe diabetic ketoacidosis following a 4-day history of cough and fever...

OBJECTIVE/BACKGROUND: Peripheral artery disease (PAD) is an important manifestation of systemic atherosclerosis. Obesity is a risk factor for atherosclerosis and for cardiovascular events. However, the relationship between obesity and PAD is unclear. We hypothesized that anthropometric measures of adiposity, in particularly of central obesity will be associated with PAD severity, in patients undergoing aorto-bifemoral bypass. METHODS: A prospective observation study was conducted...

<b/> Background : The aim was to evaluate the safety and efficacy of a high pressure, non-compliant balloon in the treatment of infrapopliteal occlusive disease in Asian patients with chronic limb threatening ischaemia (CLTI) from Singapore. Patients and methods : Prospective, multi-centre, single arm, non-randomized study. Immediate technical success, 6-month primary vessel patency (determined by Duplex ultrasonography), limb salvage, one-year clinically driven target lesion re-intervention (TLR) and amputation free survival (AFS) were the efficacy endpoints of interest...

INTRODUCTION: Percutaneous transluminal angioplasty (PTA) is commonly used to treat patients with chronic limb-threatening ischaemia (CLTI). This study aimed to examine the mortality and functional outcomes of patients with CLTI who predominantly had diabetes mellitus in a multi-ethnic Asian population in Singapore. METHODS: Patients with CLTI who underwent PTA between January 2015 and March 2017 at the Vascular Unit at Singapore General Hospital, Singapore, were studied...

BACKGROUND: Cell therapy was proposed as a procedure of indirect revascularization for patients with critical ischaemia of lower extremities for whom endovascular and surgical revascularization is impossible. We present herein a review of the state of the art of studies in the field of cell therapy of this cohort of patients. BASIC PROVISIONS: Cell therapy has proved safe, however, the results of studies of efficacy are relatively ambiguous and unconvincing. The number of patients in separately taken clinical trials is minimal...

OBJECTIVE: Major lower limb amputation is an important cause of morbidity and mortality in the USA. Little is known about the prevalence of the various indications for amputation, or if these indications have changed over time. The purpose of this study was to assess the indications for major amputation over a 17 year period and to determine whether surgical indications have shifted over this time period. METHODS: A retrospective, population based analysis of patients undergoing major amputation between 2000 and 2016 was performed using the National Inpatient Sample...

Described in the article are the results of treating a total of 44 patients who endured repeat operations for infection of aortofemoral bifurcation allografts over the period between 2001 and 2018. These patients had previously undergone reconstructive operations using various synthetic grafts for lower limb ischaemia on the background of lower-limb artery atherosclerosis and infrarenal aortic aneurysms. Infection of synthetic vascular allografts in these patients was observed both in the immediate and remote postoperative periods...

INTRODUCTION: Diabetic patients with peripheral arterial disease (PAD) are challenging to assess. Non-contrast magnetic resonance angiography (MRA) offers a safe alternative in patients with renal impairment. The study objective is to evaluate accuracy of lower limb quiescent-interval single-shot (QISS) MRA and pedal QISS-arterial spin-labelled (ASL) MRA for detection of significant stenosis in diabetic patients with PAD. METHODS: Combined QISS and QISS-ASL MRA was performed in 32 diabetic PAD patients (20 male, 12 female; mean 69 years; 8 with critical ischaemia)...
