Patients with chronic wounds are significantly impaired in their health-related quality of life (HRQoL). The validated Wound-QoL questionnaire allows assessing the impact of chronic wounds on different aspects of HRQoL including physical, psychological, and everyday life-related impairments. The aim of our study was to investigate associations of these HRQoL dimensions with age, sex, and particularly wound genesis. In this retrospective, cross-sectional, multicentre study, Wound-QoL questionnaires from clinical routine of patients with venous leg ulcers, arterial leg ulcers, mixed leg ulcers, and diabetic foot ulcers (DFU) were evaluated. Effects of wound genesis, sex, and age were assessed with analysis of variance as well as correlation and multiple linear regression analyses. The completed questionnaires of 381 patients (f = 152/m = 229; mean age 68.9) were included. The wound genesis groups showed significantly different distributions of age and sex. We also found significant differences between those groups in everyday life-related QoL, with the greatest impairments in patients with DFU. Physical QoL scores showed significant differences between men and women depending on diagnosis group: in patients with venous leg ulcers, women had greater impairment of physical QoL than men. Independent of the underlying diagnosis, women had significantly higher scores in the psychological subscale as well as in the Wound-QoL sum scale. Within the subgroup of arterial leg ulcer patients, overall HRQoL sum score was significantly worse in older patients. Regression analyses supported negative effects of DFU diagnosis and female sex on HRQoL. Our data offer evidence that HRQoL shows clinically relevant differences between patients with chronic wounds of different genesis.Moreover, our data revealed that HRQoL is associated with age and sex, which

Introduction: Chronic limb-threatening ischemia (CLTI) represents the most severe form of peripheral artery disease (PAD). Up to a third of CLTI patients are not eligible to receive first-line treatments such as bypass surgery or endovascular interventions. Epidural spinal cord stimulation (SCS) has been used as a method to improve microcirculatory blood flow and relieve ischemic pain in CTLI patients. The aim of the study was to evaluate limb salvage, ulcer closure, and clinical changes of SCS implanted CTLI patients at 1-year follow-up. Methods: Eligible patients had end-stage lower limb PAD unresponsive to medical therapy and not amenable to surgical reconstruction. Patients were candidates for amputation, but limb loss was not inevitable (Fontaine stage III and IV). Pain intensity and skin temperature in the ischemic area (visual analogue scale), quality of life (WHOQoL-BREF), and ankle/brachial blood pressure index (ABI) were recorded at routine follow-up visits. Data were analyzed retrospectively. Results: 29 patients underwent SCS implantation at one vascular center. The minimum follow-up period was 30 months. Limb survival at 1-year follow-up was 97% (28/29) and 73% (11/15) had complete closure of limb ulcers. Pain intensity, skin temperature, and quality of life progressively improved up to 12 months after implant, with Fontaine stage III patients improving more substantially than Fontaine stage IV patients. SCS therapy did not affect ABI measurement. No complications related to the device or procedure occurred. Conclusions: SCS is a valid alternative in patients unsuitable for revascularization. The quality of results depends on both a strict selection of patients by vascular specialists and the frequency of follow-up controls. The therapy may be more beneficial in patients classified as Fontaine stage III.

Background: The autologous arteriovenous fistula is the primary choice to establish hemodialysis access without high failure rates. Intraoperative ultrasound flow measurements of newly created autologous arteriovenous fistulas represent a possibility of quality control and may therefore be a tool to assess their functionality. The aim of our study was to correlate intraoperative blood flow with access patency. Methods: Between March 2012 and March 2015, intraoperative transit time flow measurements were collected on 89 patients. Measurements were performed 5–10 min after the creation of a standardized anastomosis using 3–6 mm flow probes. To examine the correlation between intraoperative blood flow and access patency, groups of patients with high (> 200 mL/min) versus low flow (< 200 mL/min) were enrolled. Patients were assessed clinically and with ultrasound every 3 months. Data were analyzed retrospectively. Results: In the current short-term follow-up, including 89 patients (age 62 ± 3 years), 61 (68.5%) of the autologous arteriovenous fistulas were currently being used in an observation period ranging from 3 months to 3 years (mean observation period 546 ± 95 days) postoperatively. The intraoperative blood flow in patients with functioning autologous arteriovenous fistula (78) was significantly higher than that of patients without functioning autologous arteriovenous fistulas (407 ± 25 vs 252 ± 42 mL/min, respectively; p < 0.005) (11). Conclusion: The intraoperative measurement of blood flow is a useful tool to predict the outcome of maturation in autologous arteriovenous fistula. With this method, technical problems can be detected and corrected intraoperatively. Routine implementation of intraoperative flow measurements has to be examined by prospective controlled trials.

ZusammenfassungModerne Zusatzbehandlungen zur herkömmlichen Wundtherapie werden häufig notwendig, da ein großer Anteil chronischer Wunden unter der Standardbehandlung nicht vollständig abheilen bzw. auch häufig rezidivieren. Die Omega3-Wundmatrix (Kerecis®) stellt eine alternative Wundauflage dar, die aus der Haut des Kabeljaus durch entsprechende Verfahren wie z.B. die Dezellularisierung gewonnen wird.Wir berichten über eine 86-jährige Patientin, die über schmerzhafte, chronische und rezidivierende Ulzeration im Bereich des rechten Unterschenkels klagte. Vorausgegangen war eine operative Behandlung der venösen Insuffizienz mit Debridement, Vakuumtherapie und Spalthauttransplantation, wonach es im Verlauf zur deutlichen Vergrößerung und Schmerzhaftigkeit der Wunde kam. Nach anschließender lokaler Wundtherapie mit Omega3- Wundmatrix (Kerecis®) kam es zu einer rasch progredienten Wundheilung mit vollständiger Abheilung der Ulzerationen innerhalb von 14 Wochen.

If there are indications for an interventional or operative treatment a variety of safe and effective therapies are available, which can significantly reduce the length of hospital stay. The option of treatment using a muscle flap is of value as a last resort in the treatment of infected vascular prosthesis in the groin of Szilagyi type III and should be used when necessary.
