Abstract
Transcutaneous oxygen tension measurement (TcPO2) is widely applied for the evaluation of chronic limb-threatening ischemia (CLTI). Nevertheless, studies that focused on the clinical value of TcPO2 have shown varying results. We identified factors that potentially play a role in TcPO2 measurement variation such as probe placement, probe temperature, and the use of a reference probe. In this review of the current literature, we assessed the application of these factors. A systematic search was conducted. Parameters that were assessed were probe placement, probe temperature, and mentioning and/or use of a reference probe. In total, 36 articles were eligible for analysis. In 24 (67%) studies, probes were placed on specific anatomical locations. Seven (19%) studies placed probes, regardless of the location of the ulcer, adjacent to an ischemic lesion or ulcer (perilesion). Selected temperature setting of the probe differed; in 18 (50%), a default probe temperature of 44°C was selected, and in 13 (36%), a different temperature was selected. In 31 (84%) studies, the use of a reference probe was not reported. Transcutaneous oxygen tension measurement is applied diversely in patients with CLTI. Homogeneity in TcPO2 protocols is warranted for reliable clinical application and to compare future TcPO2 research.

Trends in Lower Limb Amputation in Patients with Diabetic Foot Based on Vascular Intervention of Peripheral Arterial Disease in Korea: a Population-based Nationwide Study. J Korean Med Sci 2019; 34:e178. [PMID: 31269542 PMCID: PMC6609423 DOI: 10.3346/jkms.2019.34.e178] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2019] [Accepted: 06/12/2019] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Peripheral arterial disease (PAD) is known as the greatest risk factor affecting the amputation of diabetic foot. Thus, it is crucial to understand the epidemiology of PAD associated with diabetic foot and the relationship between PTA and amputation in predicting prognosis. However, no such multi-year data are available in Korea. Thus, the purpose of this study was to investigate trends of amputation involving diabetic foot based on vascular interventions for PAD in Korea. METHODS This study was conducted using six-year data obtained from Health Insurance Review and Assessment Service from January 1, 2011 to December 31, 2016. Our study included data pertaining to diabetic foot, PAD, and vascular intervention codes (percutaneous transluminal angioplasty [PTA, M6597], percutaneous intravascular installation of stent-graft [PIISG, M6605], and percutaneous intravascular atherectomy [PIA, M6620]). We analyzed the number of vascular interventions and minor and major amputations each year. The relationship between annual amputation and vascular intervention was analyzed using χ² test. RESULTS The overall number of vascular interventions increased from 253 (PTA, 111; PIISG, 140; and PIA, 2) in 2011 to 1,230 (PTA, 745; PIISG, 470; and PIA, 15) in 2016. During the same period, the number of minor amputations increased from 2,534 to 3,319 while major amputations decreased from 980 to 956. The proportion of minor amputations among patients who underwent vascular intervention was significantly increased from 19.34% in 2011 to 21.45% in 2016 while the proportion of major amputations among these patients was significantly reduced from 9.88% to 4.27%. In addition, the association between vascular intervention and amputation increased from 0.56 (spearman correlation coefficient) in 2011 to 0.62 in 2016. CONCLUSION In diabetic foot patients, increase in vascular intervention resulted in a change in amputation pattern, showing statistically significant correlation.

Adv Wound Care (New Rochelle) 2018; 7:171-176. [PMID: 29892493 DOI: 10.1089/wound.2017.0778] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Accepted: 12/22/2017] [Indexed: 02/07/2023] Open
Abstract
Objective: To establish the rate of clinical recurrence of critical limb ischemia (CLI) in diabetic patients with ischemic foot ulcers (DFUs) treated by percutaneous transluminal angioplasty (PTA). Approach: The study group was composed of 304 patients with ischemic DFUs treated by PTA. We evaluated the rate of clinical recurrence of CLI requiring a second PTA (repeated PTA [rePTA]), the factors related to CLI relapse, and the outcomes of rePTA patients. The follow-up was 12.5 ± 6.6 months. Results: Seventy-four of 304 patients (24.3%) needed rePTA. The mean time to rePTA was 3.5 ± 0.64 months. rePTA group in comparison with no rePTA group had lower rate of healing (28.5% vs. 71.9% p = 0.0001), higher rate of ulcer recurrence (20% vs. 10.3% p = 0.03), major amputation (24.3% vs. 4.3% p = 0.0005), and death (33.3% vs. 7.9% p = 0.002). Glycated hemoglobin, type A1C (HbA1c; 2.2 [1.9-2.7] p = 0.02) and dialysis (1.5 [1.4-3.6] p = 0.006) were independently associated to clinical recurrence of CLI after PTA. Innovation: To identify the outcomes of patients with clinical recurrence of CLI and the clinical factors involved to reduce the rate of restenosis after endovascular treatment and improve the rate of limb salvage. Conclusions: Clinical recurrence of CLI is associated with a high rate of nonhealing ulcer recurrence, major amputation, and death. Dialysis and impaired glycemic control were independent predictors of CLI relapse after endovascular treatment.

Abstract
BACKGROUND Diabetes mellitus places a substantial burden on society worldwide. Diabetic foot ulcers are a challenging problem for clinicians. Seven generally accepted detriments to healing of diabetic foot ulcers were identified: infection, glycaemic control, vascular supply, smoking, nutrition, deformity and offloading. The aim of this paper is to present a comprehensive evidence based review of the literature available on detriments to healing of diabetic foot ulcers. METHOD A research question was generated for each of the detriments to healing and a comprehensive review of the literature was performed using the Pubmed database in July 2014. All articles were assessed for relevancy and a level of evidence was assigned. An analysis of the total body of literature was used to assign a grade of recommendation to each detriment. RESULTS Grade A recommendation was assigned to offloading as there was good evidence supporting this intervention. Grade B recommendation was assigned to deformity as there was fair evidence consistent with the hypothesis. Infection and vascular supply had poor quality evidence supporting the research question and grade C recommendation was assigned. Grade I recommendation was assigned to glycaemic control, smoking and nutrition as there was insufficient and conflicting evidence available. CONCLUSION Our literature review revealed good evidence for some factors and insufficient literature on others. Further studies are needed to provide quality evidence regarding detriments to healing of diabetic ulcers.

Abstract
Symptoms or signs of peripheral artery disease (PAD) can be observed in up to 50% of the patients with a diabetic foot ulcer and is a risk factor for poor healing and amputation. In 2012, a multidisciplinary working group of the International Working Group on the Diabetic Foot published a systematic review on the effectiveness of revascularization of the ulcerated foot in patients with diabetes and PAD. This publication is an update of this review and now includes the results of a systematic search for therapies to revascularize the ulcerated foot in patients with diabetes and PAD from 1980 to June 2014. Only clinically relevant outcomes were assessed. The research conformed to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, and Scottish Intercollegiate Guidelines Network methodological scores were assigned. A total of 56 articles were eligible for full-text review. There were no randomized controlled trials, but there were four nonrandomized studies with a control group. The major outcomes following endovascular or open bypass surgery were broadly similar among the studies. Following open surgery, the 1-year limb salvage rates were a median of 85% (interquartile range of 80-90%), and following endovascular revascularization, these rates were 78% (70-89%). At 1-year follow-up, 60% or more of ulcers had healed following revascularization with either open bypass surgery or endovascular techniques. Studies appeared to demonstrate improved rates of limb salvage associated with revascularization compared with the results of conservatively treated patients in the literature. There were insufficient data to recommend one method of revascularization over another. There is a real need for standardized reporting of baseline demographic data, severity of disease and outcome reporting in this group of patients.

Lower-extremity arterial revascularization: Is there any evidence for diabetic foot ulcer-healing? DIABETES & METABOLISM 2015; 42:4-15.

Abstract
The presence of peripheral arterial disease (PAD) is an important consideration in the management of diabetic foot ulcers. Indeed, arteriopathy is a major factor in delayed healing and the increased risk of amputation. Revascularization is commonly performed in patients with critical limb ischaemia (CLI) and diabetic foot ulcer (DFU), but also in patients with less severe arteriopathy. The ulcer-healing rate obtained after revascularization ranges from 46% to 91% at 1 year and appears to be improved compared to patients without revascularization. However, in those studies, healing was often a secondary criterion, and there was no description of the initial wound or its management. Furthermore, specific alterations associated with diabetes, such as microcirculation disorders, abnormal angiogenesis and glycation of proteins, can alter healing and the benefits of revascularization. In this review, critical assessment of data from the literature was performed on the relationship between PAD, revascularization and healing of DFUs. Also, the impact of diabetes on the effectiveness of revascularization was analyzed and potential new therapeutic targets described.

Abstract
Diabetes mellitus is an independent risk factor for peripheral artery disease. Life expectancy is 41 months for diabetic patients with an ischemic ulcer. The characteristics of diabetic arteriopathy make its treatment more difficult than in non-diabetic patients. Few data are available about the surgical treatment of arteriopathy in diabetic patients (including angioplasty or bypass), especially in case of distal arteriopathy. The choice of the procedure depends on multiple factors such as the disease localization, its extent, distal blood flow and vascular disease-related surgical risk. The principal aim of revascularisation is to restore direct flow to the foot in order to ensure wound healing and limb salvage. With percutaneous endoluminal angioplasty, limb salvage can be achieved in more than 80% of patients at 1-3 years. The percutaneous procedure is less invasive than open surgery, there are fewer complications, and morbidity and mortality rates are reduced; moreover, a second procedure remains possible in the future. With bypass surgery, the rate of limb salvage exceeds 80% at five years. Nevertheless, peri-operative mortality reaches 3% and arterial anatomy, patient-related risks factors or venous graft availability may be limitations. New endovascular techniques especially designed for the distal arteries of the lower limbs enable very distal revascularization with morbidity and mortality rates lower than with surgery.

Abstract
OBJECTIVES Hepatocyte growth factor (HGF), the c-Met receptor, and hypoxia-inducible factor (HIF) are crucial for regenerative processes including ischemic wound healing. The aims of the present study are (a) to analyze the tissue c-Met and HIF-1α expression in skin from patients with critical limb ischemia (CLI); (b) to compare the serum HGF levels of CLI and control subjects. METHODS This is a prospective, controlled, single-center study. Thirty-seven patients were enrolled. A skin sample adjacent to the ischemic lesion was taken from 20 patients with CLI; skin samples were taken from the surgical wounds of 17 patients surgically treated for abdominal aortic aneurysm as healthy controls. Serum samples were taken in all cases. Samples were formalin fixed, paraffin embedded, and routinely processed. Tissue inflammation was histologically assessed. Immunohistochemistry was performed with antibodies against total c-Met receptor, activated Met (p-Met), and HIF-1α. RT-polymerase chain reaction was used to quantify HIF-1α mRNA. The enzyme-linked immunosorbent assay was performed to evaluate serum HGF levels. RESULTS With immunohistochemistry, while total c-Met was unchanged, different patterns of p-Met positivity were observed between CLI and control cases (p < .001). In particular, CLI skin showed a total negativity or membrane positivity for p-Met (19/20 cases), while control skin mainly showed cytoplasmic positivity in the epidermal basal layer (16/17 cases). HIF-1α was diffusely lost in CLI, but HIF-1α mRNA was threefold higher than in controls. Finally, mean serum HGF levels were 590.5 pg/mL and 2380.0 pg/mL in CLI and control groups respectively (p < .001). CONCLUSIONS In CLI patients a significant decrease in serum HGF levels, concomitant with a loss of skin HIF-1α stabilization and a lack of c-Met phosphorylation were seen, probably driving a decrease in wound-healing functions. The next hypothesis is that HGF application might reactivate the c-Met receptor, stabilizing the normal wound healing process.

Abstract
Diabetic foot (DF) is a chronic and highly disabling complication of diabetes. The prevalence of peripheral arterial disease (PAD) is high in diabetic patients and, associated or not with peripheral neuropathy (PN), can be found in 50% of cases of DF. It is worth pointing out that the number of major amputations in diabetic patients is still very high. Many PAD diabetic patients are not revascularised due to lack of technical expertise or, even worse, negative beliefs because of poor experience. This despite the progress obtained in the techniques of distal revascularisation that nowadays allow to reopen distal arteries of the leg and foot. Italy has one of the lowest prevalence rates of major amputations in Europe, and has a long tradition in the field of limb salvage by means of an aggressive approach in debridement, antibiotic therapy and distal revascularisation. Therefore, we believe it is appropriate to produce a consensus document concerning the treatment of PAD and limb salvage in diabetic patients, based on the Italian experience in this field, to share with the scientific community.

Abstract
In diabetic subjects, new less invasive therapies for critical limb ischemia (CLI) are available to obtain limb salvage. One of these is the percutaneous transluminal angioplasty (PTA), a minor surgical intervention which allows obtaining an effective revascularization, avoiding the traditional major surgery and its post-operative complications. Our case report regards a 94-year-old woman with CLI due to critical obstruction (stage IV according to Leriche's classification) of superficial femoral and popliteal arteries and infrapopliteal arteries that should have been treated by the left limb amputation considering her age, severe co-morbidities, and poor compliance. Instead of this quite common approach, our team treated the patient with PTA. This led to very good outcomes, above all in terms of pain control. PTA is able to avoid major surgery, lower intra and post-operative risks, reduce length of hospital stay, and preserve functional autonomy. Therefore, this procedure should be taken into account also for frail very elderly diabetic patients with peripheral artery disease (PAD).

Endovascular intervention in Taiwanese patients with critical limb ischemia: patient outcomes in 333 consecutive limb procedures with a 3-year follow-up. J Formos Med Assoc 2013; 113:688-95. [PMID: 25240302 DOI: 10.1016/j.jfma.2012.10.022] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2012] [Revised: 09/13/2012] [Accepted: 10/30/2012] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND/PURPOSE Midterm outcomes of endovascular intervention (EVI) for critical limb ischemia (CLI) have not been previously reported in Taiwan. This study assessed the safety, feasibility, and patient-oriented outcomes for CLI patients after EVI. METHODS From June 2005 to December 2011, 270 patients underwent EVI for CLI of 333 limbs. Primary patency (PP), assisted primary patency (AP), limb salvage, sustained clinical success (SCS), secondary SCS (SSCS), and survival were assessed using Kaplan-Meier analysis. RESULTS The procedural success rate was 89%, and the periprocedural mortality and major complication rates within 30 days were 0.6% and 6.9%, respectively. During the mean follow-up time of 27 ± 20 months (1-77), 64 patients died and 25 legs required major amputation. Eighty-one percent of the patients with tissue loss had wound healing at 6 months and 75% of the patients were ambulatory, with or without assisting devices, at 1 year. The overall survival and limb salvage rates at 3 years were 70% and 90%, respectively. The PP and AP at 1 and 3 years were 58% and 37% and 79% and 61%, respectively. The SCS and SSCS were 65% and 46% and 80% and 64% at 1 and 3 years, respectively. CONCLUSION In Taiwan, EVI was a safe and feasible procedure for CLI patients, with a high procedural success rate and lower complication rate. Sustained limb salvage and clinical success can be afforded with an active surveillance program and prompt intervention during midterm follow-up.

Abstract
This review discusses the role of endovascular treatment in diabetic patients with critical limb ischemia (CLI). Angioplasty of the femoropopliteal region achieves similar technical success and limb salvage rates in diabetic and nondiabetic patients. Angioplasty in as many as possible tibial vessels is accompanied by more complete and faster ulcer healing as well as better limb salvage rates compared to isolated tibial angioplasty. Targeted revascularization of a specific vessel responsible for the perfusion of a specific ulcerated area is a promising new approach: it replaces revascularization of the angiographically easiest-to-access tibial vessel, even if this is not directly responsible for the perfusion of the ulcerated area, by revascularization of area-specific vascular territories. In conclusion, the endovascular approach shows very high efficacy in ulcer healing for diabetic patients with CLI. Larger prospective studies are now needed to estimate the long-term results of this approach.

Abstract
Background To investigate the long-term results of global coronary and peripheral interventional treatment of diabetic foot patients. Methods We retrospectively included 220 diabetic patients (78.5 ± 15.8 years, 107 females, all with Fontaine III or IV class) who were referred to our centre for diabetic foot syndrome and severe limb ischemia from January 2006 to December 2010. Patients were evaluated by a team of interventional cardiologists and diabetologists in order to assess presence of concomitant coronary artery disease (CAD) and eventual need for coronary revascularization. Stress-echo was performed in all patients before diagnostic peripheral angiography. Patients with indications for coronary angiography were submitted to combined diagnostic angiography and then to eventual staged peripheral and coronary interventions. Doppler ultrasonography and foot transcutaneous oximetry of transcutaneous oxygen pressure (TcPO2) before and after the procedure were performed as well as stress-echocardiography and combined cardiologic and diabetic examination at 1 and 6 month and yearly. Results Stress-echocardiography was performed in 94/220 patients and resulted positive in 56 patients who underwent combined coronary and peripheral angiography. In the rest of 126 patients, combined coronary and peripheral angiography was performed directly for concomitant signs and symptoms of coronary heart disease in 35 patients. Coronary revascularization was judged necessary in 85/129 patients and was performed percutaneously after peripheral interventions in 72 patients and surgically in 13 patients. For Diabetic foot interventions the preferred approach was ipsilateral femoral antegrade in 170/220 patients (77.7%) and contralateral cross-over in 40/220 patients (18.8%) and popliteal retrograde + femoral antegrade in 10/220 patients (4.5%). Balloon angioplasty was performed in 252 legs (32 patients had bilateral disease): the procedure was successful in 239/252 legs with an immediate success rate of 94.8% and a significant improvement in TcPO2 and ABI with ulcer healing in 233/252 legs (92.4%). Freedom from major amputation was 82.8% at a mean follow-up of 3.1 ± 1.8 years (range 1 to 5 years) whereas survival was 88%. Conclusions Global coronary and peripheral endovascular management of diabetic foot syndrome patients seems to lead to an high immediate success and limb salvage rates and increasing survival compared to historical series.

Abstract
The role of peripheral arterial disease in ulcerated diabetic feet has long been underestimated. Progressive claudication, rest pain and the extent of irreversible tissue loss have frequently been indications for revascularization for neuroischaemic ulcers in diabetic patients. These typical ischaemic symptoms are warning signs that are less frequent in diabetic individuals with ischaemia than those without diabetes. Consequently, 30-50% of individuals with diabetes and foot ulcers already have gangrene at admission and are therefore often considered unsuitable for revascularization. Furthermore, the healing of a neuroischaemic ulcer is worsened by microvascular dysfunction, causing arteriovenous shunting, capillary ischaemia, leakage and venous pooling. Therefore, the threshold of revascularizing neuroischaemic ulcers should be lower than that of purely ischaemic ulcers. Comorbidity, ulcer characteristics and infection affect the decision as to when to intervene, as do the severity and extent of occlusive arterial lesions. The window of opportunity for vascular intervention in the neuroischaemic diabetic foot should not be missed, and the need for early vascular intervention as an integrated part of a strategy to achieve healing should be emphasized. Noninvasive vascular testing should be performed on all individuals with an ulcerated diabetic foot. The arterial tree should be imaged if noninvasive tests indicate ischaemia or when mild or questionable ischaemia is diagnosed and conservative treatment does not promote ulcer healing in 6 weeks. Revascularization should be performed whenever feasible to repair distal perfusion to achieve ulcer healing.

Abstract
In several large recent observational studies, peripheral arterial disease (PAD) was present in up to 50% of the patients with a diabetic foot ulcer and was an independent risk factor for amputation. The International Working Group on the Diabetic Foot therefore established a multidisciplinary working group to evaluate the effectiveness of revascularization of the ulcerated foot in patients with diabetes and PAD. A systematic search was performed for therapies to revascularize the ulcerated foot in patients with diabetes and PAD from 1980-June 2010. Only clinically relevant outcomes were assessed. The research conformed to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the Scottish Intercollegiate Guidelines Network methodological scores were assigned. A total of 49 papers were eligible for full text review. There were no randomized controlled trials, but there were three nonrandomized studies with a control group. The major outcomes following endovascular or open bypass surgery were broadly similar among the studies. Following open surgery, the 1-year limb salvage rates were a median of 85% (interquartile range of 80-90%), and following endovascular revascularization, these rates were 78% (70.5-85.5%). At 1-year follow-up, 60% or more of ulcers had healed following revascularization with either open bypass surgery or endovascular revascularization. Studies appeared to demonstrate improved rates of limb salvage associated with revascularization compared with the results of medically treated patients in the literature. There were insufficient data to recommend one method of revascularization over another. There is a real need for standardized reporting of baseline demographic data, severity of disease and outcome reporting in this group of patients.

Abstract
Diabetic foot ulceration (DFU) is recognized as one of the most serious complications of diabetes. Active revascularisation plays a crucial role in achieving ulcer healing. Non-surgical, minimally invasive, revascularisation options for DFU have expanded over the last decade and have become a prominent tool to prevent amputation. Endovascular treatment of arterial DFU lesions is mainly concentrated in the below-the-knee arteries. The outcome of both open surgery and endovascular treatment is broadly spoken the same for the endpoints ulcer healing and limb salvage and is between 78% and 85%. The choice between endovascular treatment and open surgery should always be the outcome of a team discussion. Local expertise plays an important role in these discussions. In many institutions, the endovascular approach has currently become the first choice treatment option. The revascularisation of below-the-knee vessels needs experienced hands, team discussion and the right set of devices. Centralisation in DFU centres is therefore probably the best guaranty for the best outcome.

Abstract
OBJECTIVES Peripheral vascular disease (PVD) is an important limiting factor for healing in neuroischemic or ischemic diabetic foot ulcer. The purpose of this study was to identify factors related to healing in patients with diabetes with foot ulcers and severe PVD. METHODS Patients with diabetes with a foot ulcer, consecutively presenting at a multidisciplinary foot center with a systolic toe pressure <45 mm Hg or an ankle pressure <80 mm Hg were prospectively included, followed according to a preset program, and with the exception of specified exclusions, subjected to angiography offered vascular intervention when applicable. All patients had continuous follow-up until healing or death irrespective of the type of vascular intervention. RESULTS One thousand one hundred fifty-one patients were included. Eighty-two percent had a toe pressure <45 mm Hg and 49% had an ankle pressure <80 mm Hg. Eight hundred one patients (70%) underwent an angiography. Out of these, 63% had vascular intervention, either percutaneous transluminal angioplasty (PTA; 39%) or reconstructive surgery (24%). Nine percent of the patients had one or more complications after angiography. PTA was multisegmental in 46% and to the crural arteries in 46%. Reconstructive surgery was distal in 51%. Age (P < .001), renal function impairment (P = .005), congestive heart failure (P = .01), number and type of ulcer (P < .001), and severity of PVD (P = .003) affected the outcome of ulcers. PTA and reconstructive vascular surgery increased the probability of healing without amputation (odds ratio [OR], 1.77 and 2.05, respectively). CONCLUSION Probability of ulcer healing is strongly related to comorbidity, extent of tissue involvement, and severity of PVD in patients with diabetes with severe PVD.

Abstract
Purpose: Lower extremity amputation prevention (LEAP) is an ongoing program in our institution aimed at salvaging limbs in patients with critical limb ischemia (CLI). Patients in the LEAP program with reconstructible anatomy on initial Doppler imaging received either bypass surgery or percutaneous transluminal balloon angioplasty (PTA). We present the 3 year limb salvage rate and angiographic disease patterns in 42 consecutive diabetic patients with CLI who received PTA in 2005. Methods and Material: 26 women and 16 men with diabetes between the ages of 45 and 91 years old (mean age, 70.8 years) received PTA in 2005. Presenting symptoms were rest pain (n = 22), pre-existing gangrene (n = 17), non-healing ulcer (n = 16) and cellulitis (n = 2). The aim of the PTA was to achieve straight-line flow from the abdominal aorta down to the patent dorsalis pedis or plantar arch, with limb salvage as the ultimate outcome. Failure of treatment was defined as any amputation above the level of a Syme’s amputation or the need for further surgical bypass. Technical success was achieved in 90% (38 out of 42 patients). Results: Limb salvage rates were 93% at 1 month, 87% at 3 months, 82% at 6 months, 78% at 1 year, 69% at 2 years and 66% at 3 years. Mortality was 17% (n = 7) at 3 years. Of the 13 patients with failed therapy, 3 underwent bypass, 9 had amputations and 1 had bypass followed by amputation. Four of the cases required further intervention due to worsening gangrene and infection, while the remaining was due to persistent rest pain. The rest of the 32 patients had no lower limb related issues at the end of 3 years, with improvement of the presenting symptoms. Patterns of treated segments were aortoiliac occlusions (n = 3), pure infrapopliteal disease (n = 3), femoropopliteal with at least 1 good infrapopliteal run-off vessel (n = 14) and combined femoropopliteal and infrapopliteal disease (n = 25). Conclusion: Involvement of infrapopliteal vessels that needs to be treated is common in Asian diabetics. While early limb salvage rates up to 1 year are similar, the 3 year limb salvage rates in Asian diabetics are lower than the western population.

Abstract
The diabetic foot constitutes a tremendous challenge for patients, caregivers and the health care system. The International Consensus Document of 1999 was a milestone in the recognition of the importance and consequences of the diabetic foot. Since then, many original papers have been published in this area. Large cohort studies have given us a deeper understanding regarding factors related to the outcome of diabetic foot ulcers: according to these studies, the severity of diabetic foot ulcers is greater than previously reported. More than 50% of individuals' foot ulcers have signs of infection at admission, and one-third have signs of both peripheral artery disease (PAD) and infection. The co-morbidities increase significantly with increasing severity of the foot disease. However, the trend in all these studies is a successive improvement in healing rate (50-60% at 20 weeks follow-up, > 75% at 1 year). It is important to differentiate between neuropathic and neuro-ischaemic ulcers with regard to factors related to outcome and co-morbidities.Recent research has emphasized the importance of psychological factors in the development and outcome of diabetic foot ulcers. Studies have shown that perceptions of the individual's own risks based on symptoms, and their own beliefs in the efficacy of self-care, can affect foot-care practice.The importance and influence of the health care organization and reimbursement should not be underestimated, both in the prevention and management of diabetic foot lesions. The diabetic foot should be considered a lifelong condition, as having had one ulcer dramatically increases the risk of developing a new ulcer. In an individual with diabetes and a foot ulcer, the ulcer should be considered as a sign of multi-organ disease, and a holistic approach to both management and prevention is recommended.

Abstract
Introduction: Lower extremity amputation prevention (LEAP) is an ongoing programme in our institution aimed at limb salvage in patients with critical limb ischaemia (CLI). Patients in the LEAP programme with reconstructible anatomy on initial Doppler imaging received either bypass surgery or percutaneous transluminal balloon angioplasty (PTA). We describe the 1-year limb salvage rates in 46 consecutive patients with CLI who received PTA in 2005.
Clinical Picture: A total of 46 patients, 28 women and 18 men, between the ages of 40 and 91 years old (mean age, 70.8) received PTA in 2005. The most common presenting symptom was rest pain (n = 23), followed by pre-existing gangrene (n = 20), non-healing ulcer (n = 17) and cellulitis (n = 8). The majority of the patients (57%) had 3 to 4 risk factors. Diabetes mellitus (91%) and hypertension (80%) were the 2 most common risk factors. The patients were kept under surveillance for periods ranging from 12 to 21 months with a mean of 13.3 months, both clinically and with haemodynamic measurements [ankle-brachial index (ABI), toe pressure (TP) and digital-brachial index (DBI)].
Treatment: The aim of PTA is to achieve straight-line flow from the abdominal aorta down to either a patent dorsalis pedis or plantar arch with limb salvage as the ultimate goal. The patterns of the treated segments were as follows: aorto-iliac occlusions (n = 3), pure infrapopliteal disease (n = 5), femoropopliteal disease with at least 1 good infrapopliteal run-off vessel (n = 16) and combined femoropopliteal and infrapopliteal disease (n = 25). Technical success was achieved in 89% of patients (41 out of 46 patients). The most common cause of technical failure is the inability to cross long chronic total occlusions.
Outcome: Paired T test was performed and showed statistically significant improvement in haemodynamic markers within the technically successful group. This included increase in the mean ABI from 0.62 (pre-angioplasty) to 0.91 (Day 1 post-angioplasty), an increase of 0.29 [95% confidence interval (95% CI), 0.1953 to 0.3875; P <0.001]. One year post-angioplasty, the mean ABI was 0.84, an increase of 0.22 (95% CI 0.1512 to 0.3121; P <0.001). There was also significant increase in the mean DBI of 0.17 from 0.23 to 0.41 (pre-angioplasty versus Day 1 post angioplasty – 95% CI of 0.1006 to 0.2433; P <0.001). In addition, significant increase in the mean TP of 28.2 mmHg from 36.8 to 63.2 mmHg (pre-angioplasty versus Day 1 post angioplasty – 95% CI, 18.493 to 37.939; P <0.001) was also noted. Of the 23 patients who presented with rest pain, total abolishment of symptoms was achieved in 21 patients (91%). Healing of pre-existing gangrene was attained in 15 patients (66%). Five patients subsequently received minor amputation for pre-existing gangrene. Clinical improvement in all the patients who presented with non-healing ulcers (n = 17) and cellulitis (n = 8) was attained. More importantly, all healed ulcers remained healed throughout the study period. The limb salvage rates were 93% at 1 month, 87% at 3 months, 82% at 6 months and 78% at 1 year.
Conclusion: Angioplasty is a safe and effective limb salvage method in patients with CLI and has a high 1-year limb salvage rate.

Abstract
AIMS To explore the relationships between time to healing of diabetic foot ulcers and baseline characteristics of both patients and their ulcers. METHODS All patients were included who were referred to a specialist clinic over a 4-year period. Age, gender, type and duration of diabetes, ulcer site, ulcer duration and baseline characteristics were recorded. Postcode was used to derive an index of social deprivation. Patients were followed up to 1 year. The primary outcome measure was time to healing. Those who died or had an ulcer-related amputation were censored at the time of death or amputation and classified as unhealed. RESULTS Mean age of 449 participants (63.7% male) was 66.7 years; 42.7% had evidence of peripheral arterial disease, and 80% had peripheral neuropathy. Median ulcer duration at presentation was 29 days; 60.5% ulcers had an area of < 1 cm(2) and 68.3% of all ulcers healed without amputation during the follow-up period. Univariate analysis revealed dose-response relationships between time to healing and increasing duration of diabetes, increasing ulcer area, ulcer site and peripheral arterial disease. No associations were found with age, gender, diabetes type, deprivation index, peripheral neuropathy or infection. The relationship between healing time and ulcer area, peripheral arterial disease and diabetes duration remained significant on multivariate analysis. CONCLUSIONS The dominant factors influencing healing are cross-sectional area at presentation and the degree of peripheral arterial disease. Further work is needed to define how those at greatest risk may be identified and best managed.

Abstract
OBJECTIVES Although complete ulcer healing is the mandatory primary efficacy criterion in current European guidelines for drug trials in critical limb ischemia (CLI), the appropriateness of this endpoint has been questioned for some time. We carried out a systematic review to assess the value of this endpoint in studies on reconstructive measures, considered to be the standard of care for CLI. METHODS A computerized literature search (1985-2005) was performed to track down clinical studies on endovascular and surgical interventions by using the search terms CLI and ulcer healing and their synonyms. RESULTS 1,914 papers on revascularization in CLI were identified. Complete ulcer healing was reported in 17 studies (0.9%). Among these, there were no randomized controlled trials, five prospective cohorts on endovascular procedures, and six retrospective cohorts for endovascular and surgical procedures, respectively. If healing rates or time to ulcer healing were available, they differed greatly between the studies without consistent correlation to types of therapy. CONCLUSIONS In past and current literature, complete ulcer healing is not a consistently reported criterion for success of revascularization in CLI. Thus, its appropriateness for efficacy assessment of drug studies in CLI patients has to be questioned.
