- Objectives: To study international differences in incidence and practice patterns as well as time trends in lower limb amputations related to peripheral arterial disease and/or diabetes mellitus. Methods: Data on lower limb amputations during 2010-2014 were collected from population based administrative data from countries in Europe and Australasia participating in the VASCUNET collaboration. Amputation rates, time trends, in hospital or 30 day mortality and reimbursement systems were analysed. Results: Data from 12 countries covering 259 million inhabitants in 2014 were included. Individuals aged >= 65 years ranged from 12.9% (Slovakia) to 20.7% (Germany) and diabetes prevalence among amputees from 25.7% (Finland) to 74.3% (Slovakia). The mean incidence of major amputation varied between 7.2/100,000 (New Zealand) and 41.4/100,000 (Hungary), with an overall declining time trend with the exception of Slovakia, while minor amputations increased over time. The older age group (>= 65 years) was up to 4.9 times more likely to be amputated compared with those younger than 65 years. Reported mortality rates were lowest in Finland (6.3%) and highest in Hungary (20.3%). Countries with a fee for service reimbursement system had a lower incidence of major amputation compared with countries with a population based reimbursement system (14.3/100,000 versus 18.4/100,000, respectively, p < .001). Conclusions: This international audit showed large geographical differences in major amputation rates, by a factor of almost six, and an overall declining time trend during the 4 year observation of this study. Diabetes prevalence, age distribution, and mortality rates were also found to vary between countries. Despite limitations attributable to registry data, these findings are important, and warrant further research on how to improve limb salvage in different demographic settings.

- Peripheral artery disease affects >200 million people worldwide and is associated with significant limb and cardiovascular morbidity and mortality. Limb revascularization is recommended to improve function and quality of life for symptomatic patients with peripheral artery disease with intermittent claudication who have not responded to medical treatment. For patients with critical limb ischemia, the goals of revascularization are to relieve pain, help wound healing, and prevent limb loss. The baseline risk of cardiovascular and limb-related events demonstrated among patients with stable peripheral artery disease is elevated after revascularization and related to atherothrombosis and restenosis. Both of these processes involve platelet activation and the coagulation cascade, forming the basis for the use of antiplatelet and anticoagulant therapies to optimize procedural success and reduce postprocedural cardiovascular risk. Unfortunately, few high-quality, randomized data to support use of these therapies after peripheral artery disease revascularization exist, and much of the rationale for the use of antiplatelet agents after endovascular peripheral revascularization is extrapolated from percutaneous coronary intervention literature. Consequently, guideline recommendations for antithrombotic therapy after lower limb revascularization are inconsistent and not always evidence-based. In this context, the purpose of this structured review is to assess the available randomized data for antithrombotic therapy after peripheral arterial revascularization, with a focus on clinical trial design issues that may affect interpretation of study results, and highlight areas that require further investigation.

- Objective: The objective of this study was to evaluate the risk of recurrent ischaemic stroke in patients with ultrasound assessed symptomatic mild carotid artery stenosis (20-49% NASCET) treated solely with modern medical treatment. Method: This was a retrospective, observational register cohort study. Three groups of patients were recruited from a database of all carotid Doppler ultrasound examinations performed in the Gothenburg region between 2004 and 2009. Patients with symptomatic mild carotid artery stenosis (n = 162) were compared with patients with asymptomatic carotid artery stenosis (n = 301) of equal degree and a group of patients with surgically (CEA) treated symptomatic moderate or severe carotid artery stenosis (n = 220). Kaplan-Meier estimates and Cox proportional hazard models were used to compare the primary outcome (ipsilateral ischaemic stroke) between groups. Results: After a 3 year follow up, the cumulative incidence of recurrent ipsilateral stroke in patients with symptomatic mild carotid artery stenosis was 7.4%. Patients with symptomatic mild carotid artery stenosis had a substantially increased risk of recurrent ipsilateral stroke compared with asymptomatic patients with equal degree of stenosis (HR 5.5. 95% CI 1.8-17.1; p = .003) as also compared with patients with CEA treated symptomatic moderate or severe stenosis (HR 7.8. 95% CI 1.62-37.8; p = .011). Conclusions: The present study on patients with symptomatic mild carotid artery stenosis, as determined by Doppler ultrasound, shows that there is still a substantial risk of recurrent stroke in this group.

- Objectives: Acute lower limb ischaemia (ALLI) is a potentially fatal, limb threatening medical emergency. Early treatment is essential for a good outcome. The aim was to describe the early chain of care in ALLI focusing on lead times and emergency management in order to identify weak links for improvement. Methods: This was a retrospective, descriptive case study. This study analysed the medical records of all patients with a main discharge diagnosis of ALLI between January 2009 and December 2014. Predetermined emergency care data on lead times, diagnosis recognition, presenting symptoms, emergency care treatment and outcome were collected for patients who were transported by the Emergency Medical Service (EMS) and those who were not. Results: In total, 552 medical records were audited of which 195 patients fulfilled the inclusion criteria and were analysed. Among them were 117 (60%) transported by the EMS. The median time from symptom onset to revascularisation was 23 (interquartile range [IQR] 10-55; EMS transported) and 93 (IQR 42-152, not EMS transported) hours (p < .01). The time from symptom onset to arrival in hospital was 5 (IQR 2-26; EMS transported) and 48 (IQR 6-108; not EMS transported) hours. After arrival in hospital, the median time to first doctor evaluation was 51 (IQR 28-90; EMS transported) and 80 (IQR 44-169; not EMS transported) minutes, p = .01. Low molecular weight heparin (LMWH) was given to 72% of patients in the emergency department (ED) and a multivariate analysis showed that the use of LMWH was associated with a more favourable outcome. Conclusions: Both the time spent in the ED and the time from the onset of symptoms to revascularisation were considerably longer than optimal. Time delays in the early treatment chain can mainly be attributed to "patient delay" and a considerable time spent in hospital before revascularisation. The use of LMWH as an integral part of ED management was associated with a better outcome. (C) 2017 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.

- © 2014 European Society for Vascular Surgery. Objectives The risk of recurrent stroke in patients with symptomatic carotid artery stenosis is highest in the first weeks after a transient ischemic attack (TIA) or minor stroke and can be reduced with carotid endarterectomy (CEA). The optimal timing of CEA remains a controversial issue since very urgent CEA is associated with an increased procedural risk. The aim of this study was to determine the risk of very early recurrent stroke in a population with symptomatic high grade carotid stenosis. Methods Data were analyzed on all patients with ocular TIA, TIA, or minor stroke with >70% carotid stenosis as assessed by carotid ultrasound at Sahlgrenska University Hospital during the periods 2004-2006 and 2010-2012. The two time periods were chosen to minimize selection bias and to analyze changes over time. The risk of recurrent stroke within 30 days of the referring event was assessed. Results 397 patients with symptomatic carotid stenosis were identified. The risk of recurrent stroke in the total cohort was 2.0% (CI 95% 0.6-3.4) by day 2, 4.0% (CI 95% 2.0-5.9) by day 7, and 7.5% (CI 95% 4.4-10.6) by day 30. There was no significant difference between the two time periods. Patients with minor stroke had a significantly higher risk of recurrent stroke than patients with TIA or ocular TIA as the referring event. Conclusions The data suggest that the early risk of recurrent stroke in symptomatic significant carotid stenosis is not as high as some earlier studies have shown. The risk is similar to several studies in which a modern medical treatment regime could be assumed.
