    Objectives: The number of elderly people is increasing; inevitably, the result will be more patients with critical limb ischaemia (CLI) in the future. Tissue loss in CLI is related to a high risk of major amputation. The aim of this study was to analyze the treatment process from referral to revascularisation, to discover possible delays and reasons behind them, and to distinguish patients benefitting the most from early revascularisation. Methods: A retrospective analysis was performed of 394 consecutive patients with a combined 447 affected limbs, referred to the outpatient clinic during 2010-2011 for tissue loss of suspected ischaemic origin. Results: For 246 limbs revascularisation was scheduled. After changes in the initial treatment strategy, endovascular treatment (ET) was performed on 221 and open surgery (OS) on 45 limbs. Notably there was crossover after ET in 17.0% of the procedures, and re-revascularisations were required in 40.1% after ET and 31.1% after OS. The median time from referral to revascularisation was 43 days (range 1-657 days) with no significant difference between ET and OS. For 29 (11.8%) patients the ischaemic limb required an emergency operation scheduled at the first visit to the outpatient clinic. For 25 (10.2%) patients the situation worsened while waiting for elective revascularisation and an emergency procedure was performed. Diabetic patients formed the majority of the study population; with 159 diabetic feet undergoing revascularisation. In multivariate analysis, diabetes was associated with poor limb salvage. When revascularisation was achieved within 2 weeks, no difference was seen in limb salvage. However, when the delay from first visit to revascularisation exceeded 2 weeks, limb salvage was significantly poorer in diabetic patients. Conclusions: Diabetic ulcers always require vascular evaluation, and when.ischaemia is suspected the diagnostics should be organised rapidly to ensure revascularisation without delay, according to this study within 2 weeks from the first evaluation.

    Background and Aims: The present standard of care in treating lower extremity soft tissue sarcomas is function-sparing, limb-preserving resection and reconstruction with or without oncological therapy. The aim of this pilot study was to test the suitability and adequacy of the Finnish translations of two functional outcome questionnaires (Toronto Extremity Salvage Score and Musculoskeletal Tumor Society score) and to perform a preliminary investigation of functional outcomes of Finnish lower-limb soft tissue sarcoma patients after operative treatment. Materials and Methods: Between June 2015 and December 2015, consecutive surgically treated outpatients were asked to participate in the study. Demographic, clinical, surgical, and oncological outcome data were collected. Two functional outcome questionnaires were used (Toronto Extremity Salvage Score and Musculoskeletal Tumor Society scores). A comparative analysis is presented. Results: A total of 19 lower-limb soft tissue sarcoma patients with a mean follow-up time of 2 years and 10 months were included. All (n = 19) invited patients participated in the study. Mean age was 62.3 years. In total, 13 had high-grade sarcomas. Eight wounds were closed directly, four used skin grafts, and five required flap reconstructions. One patient required a tumor prosthesis, and one required a rotationplasty. A total of 14 patients received oncological therapy. No problems or difficulties were reported in using and completing the Finnish versions of the Toronto Extremity Salvage Score or Musculoskeletal Tumor Society questionnaires. The overall Toronto Extremity Salvage Score and Musculoskeletal Tumor Society scores were 88 and 76, respectively. Conclusion: This pilot study suggests that the Finnish versions of the Toronto Extremity Salvage Score and Musculoskeletal Tumor Society questionnaires are suitable for measuring functional outcome after lower extremity soft tissue sarcomas treatment. Functional outcomes vary from moderate to excellent.

    Background: Severe frostbite can result in devastating injuries leading to significant morbidity and loss of function from distal extremity amputation. The modern day management approach to frostbite injuries is evolving from a historically very conservative approach to the increasingly reported use of early interventional angiography and fibrinolysis with tPA. The aim of this study was to evaluate the results of our frostbite treatment protocol introduced 3 years ago. Methods: All frostbite patients underwent first clinical and then Doppler ultrasound examination. Angiography was conducted if certain clinical criteria indicated a severe frostbite injury and if there were no contraindications to fibrinolysis. Intra-arterial tissue plasminogen activator (tPA) was then administered at 0.5-1mg/h proximal to the antecubital fossa (brachial artery) or popliteal fossa (femoral artery) if angiography confirmed thrombosis, as well as unfractionated intravenous heparin at 500 units/h. The vasodilator iloprost was administered intravenously (0.5-2.0ng/kg/min) in selected cases. Results: 20 patients with frostbite were diagnosed between 2013-2016. Fourteen patients had a severe injury and angiography was performed in 10 cases. The total number of digits at risk was 111. Nine patients underwent fibrinolytic treatment with tPA (including one patient who received iloprost after initial non response to tPA), 3 patients were treated with iloprost alone and 2 patients received neither treatment modality (due to contraindications). The overall digital salvage rate was 74.8% and the Hennepin tissue salvage rate was 81.1%. One patient developed a catheter-site pseudoaneurysm that resolved after conservative treatment. Conclusions: Prompt referral to a facility where interventional radiology and 24/7 laboratory services are available, and the combined use of tPA and iloprost, may improve outcome after severe frostbite.

    Objective: Toe pressure (TP) is an accurate indicator of the peripheral vascular status of a patient and thus cardiovascular risk, with less susceptibility to errors than ankle-brachial index (ABI). This study aimed to analyze how ABI and TP measurements associate with overall survival and cardiovascular death and to analyze the TP of patients with ABI of 0.9 to 1.3. Methods: The first ABI and TP measurements of a consecutive 6784 patients treated at the Helsinki University Hospital vascular surgery clinic between 1990 and 2009 were analyzed. Helsinki University Vascular Registry and the national Cause of Death Registry provided the data. Results: The poorest survival was in patients with ABI >1.3 (10-year survival, 15.3%; hazard ratio, 2.2; 95% confidence interval, 1.9-2.6; P <.0001; reference group, ABI 0.9-1.3), followed by the patients with TP = 80 mm Hg). The best 10-year survival was in patients with TP >= 80 mm Hg (43.9%). Of the 642 patients with normal ABI (0.9-1.3), 18.7% had a TP 50 mm Hg. Conclusions: Low TP is associated significantly with survival and cardiovascular mortality. Patients with a normal ABI may have lower extremity artery disease (LEAD) and a considerable risk for a cardiovascular event. If only the ABI is measured in addition to clinical examination, a substantial proportion of patients may be left without LEAD diagnosis or adequate treatment of cardiovascular risk factors. Thus, especially if ABI is normal, LEAD is excluded only if TPs are also measured and are normal.
