- In 98 patients undergoing elective vascular surgery, specimens for bacterial cultures were obtained from urine, ischaemic ulcers, incisional wounds and the implanted grafts. Wound and graft infections were registered and compared with the results of these cultures and suspected risk factors in an attempt to find the source of infections. Antibiotic prophylaxis with cefuroxime was given for 24 h beginning at the start of surgery. Patients with ischaemic ulcers also received "spread prophylaxis", directed against isolated bacteria, for ten days. Three cases of graft infection and twelve cases of wound infection occurred. Positive postoperative cultures from wounds did not correlate with pre- or peroperative cultures. Peroperative cultures revealed small numbers of staphylococcus epidermidis in eleven patients, and none of them developed graft infection. Ischaemic ulcers, diabetes or re-do procedures were not accompanied by a significantly increased frequency of wound or graft infection, although each of three patients with graft infection had one of these risk factors. Bacteria, sensitive to cefuroxime, were found in one graft infection, six wound infections, and in two patients with urosepsis, whereas cefuroxime resistant organisms were isolated from one graft infection and three infected wounds. One of the three graft infections was probably caused by bacteria originating from the patient's ischaemic ulcer. In the other two patients the source of bacteria could not be determined. Cefuroxime seems to be an adequate alternative for prophylaxis of vascular graft infection, but in some patients with bacteriuria or indwelling catheters, a one day regimen may be too short.

- BACKGROUND AND AIMS: Although endovascular stent treatment is increasingly used in infrainguinal atherosclerotic occlusive disease, outcome with focus on gender differences has not been reported in detail.MATERIAL AND METHODS: One hundred and twelve consecutive patients (67 [60%]) women, undergoing endovascular nitinol stent treatment of atherosclerotic lesions in the femoropopliteal segment were analysed concerning improvement in ankle brachial index (ABI), reinterventions, complications, amputation and survival rates up to 12 months after intervention. Risk factors for amputation and death were analyzed with logistic regression.RESULTS: At presentation, women showed critical limb ischemia (CLI) more often than men (87% vs. 58 %; P = 0.001). After 12 months ABI had improved (from 0.40 ± 0.26 at baseline to 0.86 ± 0.22 after 12 months, P < 0.001), but 16 patients (15%) had been amputated and 27 patients (24 %) had died. After adjustment for age, diabetes mellitus and smoking, female gender was an independent risk factor for amputation (OR 9.0; 95% CI 1.1-76.5; P = 0.045).CONCLUSIONS: Stent treatment of lesions in the femoropopliteal segment had favourable effects on ABI and limb salvage. Treated women more often had CLI and ran a higher risk for amputation within 12 months than men. This might reflect failure of clinicians to adequately appreciate symptoms of atherosclerotic leg artery disease in women.

- Background Intermittent claudication (IC) is commonly caused by lesions in the superficial femoral artery (SFA), yet invasive treatment is still controversial and longer term patient-reported outcomes are lacking. This prospective randomized trial assessed the 24-month impact of primary stenting with nitinol self-expanding stents compared to best medical treatment (BMT) alone in patients with stable IC due to SFA disease on health-related quality of life (HRQoL). Methods One hundred patients with stable IC due to SFA disease treated with BMT were randomized to either stent (n = 48) or control (n = 52) group. HRQoL assessed by Short Form 36 Health Survey (SF-36) and EuroQoL 5-dimensions (EQ5D) 24 months after treatment were primary outcome measures. Walking Impairment Questionnaire, ankle-brachial index (ABI), and walking distance were secondary outcomes. Results Significantly better SF-36 Physical Component Summary (P = 0.024) and physical domain scores such as Physical Function (P = 0.012), Bodily Pain (P = 0.002), General Health (P = 0.037), and EQ5D (P = 0.010) were reported in intergroup comparison between the stent and the control group. Both ABI (from 0.58 +/- 0.11 to 0.85 +/- 0.18; P < 0.001 in the stent group and from 0.63 +/- 0.17 to 0.69 +/- 0.18; P = 0.036 in the control group) and walking distance (from 170 +/- 90 m to 616 +/- 375 m; P < 0.001 in the stent group and from 209 +/- 111 m to 331 +/- 304 m; P = 0.006 in the control group) improved significantly in intragroup comparisons. Conclusions In patients with IC caused by lesions in the SFA, primary stenting compared to BMT alone was associated with significant improvements in HRQoL, ABI, and walking distance durable up to 24 months of follow-up.

- OBJECTIVES: In spite of recommendations advocating conservative best medical treatment, many patients with infrainguinal intermittent claudication (IC) are treated by invasive open and endovascular methods. This study aims to evaluate the incidence and 1-year results of all such treatments during 2009 in Sweden.METHODS: The design was a one-year follow-up through the Swedish Vascular Registry (Swedvasc) of all 775 patients from the Swedish population of 10 million inhabitants in whom 843 invasive infrainguinal procedures (796 index procedures and 47 secondary procedures) were performed for IC in 2009. Index procedures were open surgery in 290 (37%) patients, bilateral in nine cases, giving a total of 299 limbs, endovascular treatment in 447 (58%) patients, bilateral in 10, giving a total of 457 limbs, and hybrid treatment in 38 (5%) patients, bilateral in two cases, giving a total of 40 limbs. Data were analysed both with regard to the number of patients (775) and the number of procedures (843). Clinical outcome was calculated from patient-reported leg function (unchanged, improved, deteriorated) and whether amputation had been necessary or death had occurred. Patent reconstruction at 1 year was also counted as improvement.RESULTS: Improvement at 1 year was seen in 567 (73.2%) patients, (225 [77.6%] in the open surgery group, 320 [71.6%] in the endovascular treatment group, and 22 [57.9%] in the hybrid treatment group). No significant difference was found between the open surgery and endovascular treatment groups comprising 737/775 patients (p = .350). Hybrid treatment gave significantly worse results (p = .046). Fifty-seven (7.3%) patients reported unchanged limb function and 32 (4.1%) patients reported deterioration. Within 30 days two patients died and one patient underwent amputation. Within 1 year 10 patients underwent 11 amputations: five (1.7%) in the open surgery group, three (0.6%) in the endovascular treatment group, and two (7.5%) in the hybrid treatment group; one underwent bilateral amputation (p = .07). Twenty-two patients died: 10 (3.4%) in the open surgery group, 12 (2.7%) in the endovascular treatment group and none in the hybrid treatment group (p = .465).CONCLUSIONS: Reported improvement at 1 year was 73.2% in patients invasively treated for infrainguinal IC. Patients reporting an unchanged or deteriorated clinical state are a considerable clinical challenge. Further studies to determine whether or not invasive treatment of infrainguinal IC is appropriate are justified. © 2014 European Society for Vascular Surgery. Published by Elsevier Ltd.
