Background: In vascular medicine, peripheral arterial disease (PAD) and diabetic foot syndrome (DFS) are often considered synonymous with respect to the need for revascularization. In PAD patients, clinical symptoms reflect the degree of atherosclerotic disease, since peripheral innervation, including pain sensation, is not usually compromised. In DFS patients, however, symptoms of relevant foot ischemia are often absent and progression of ischemia goes unnoticed owing to diabetic polyneuropathy, the loss of nociception being the main trigger for foot ulcers. This review analyzes the fundamental differences between PAD and DFS against the background of polyneuropathy. Methods: The literature research for the 2014 revision of the German evidence-based S3-PAD-guidelines was extended to 2023. Results: Vascular examination is imperative for both, PAD and DFS. Stage-dependent revascularization is of utmost importance in PAD patients, especially those suffering from critical limb-threatening ischemia (CLTI). Successful therapy of DFS goes further, including infection and metabolic control, wound management, offloading the foot and lifelong prophylaxis in the course of a multidisciplinary treatment concept. Revascularization is not needed in all cases of DFS. Conclusions: There are fundamental differences between PAD and DFS with respect to pathophysiology, the anatomical distribution of arterial occlusive processes, the clinical symptoms, the value of diagnostic tools such as the ankle-brachial index, and classification. Also, therapeutic concepts differ substantially between the two patient populations. [ABSTRACT FROM AUTHOR]

Background and purpose: Lower-extremity amputations (LEAs) in people with diabetes are associated with reduced quality of life and increased health care costs. Detailed knowledge on amputation rates (ARs) is of utmost importance for future health care and economics strategies. We conducted the present cohort study in order to estimate the incidences of LEA as well as relative and attributable risk due to diabetes and to investigate time trends for the period 2008-2012. Methods: On the basis of the administrative data from three large branches of German statutory health insurers, covering ~34 million insured people nationwide (about 40% of the German population), we estimated age-sex-standardized AR (first amputation per year) in the populations with and without diabetes for any, major, and minor LEAs. Time trends were analyzed using Poisson regression. Results: A total of 108,208 individuals (diabetes: 67.3%; mean age 72.6 years) had at least one amputation. Among people with diabetes, we observed a significant reduction in major and minor ARs during 2008-2012 from 81.2 (95% CI 77.5-84.9) to 58.4 (55.0-61.7), and from 206.1 (197.3-214.8) to 177.0 (169.7-184.4) per 100,000 person-years, respectively. Among people without diabetes, the major AR decreased significantly from 14.3 (13.9-14.8) to 11.6 ([11.2-12.0], 12.0), whereas the minor AR increased from 15.8 (15.3-16.3) to 17.0 (16.5-17.5) per 100,000 person-years. The relative risk (RR) comparing the diabetic with the nondiabetic populations decreased significantly for both major and minor LEAs (4% and 5% annual reduction, respectively). Conclusion: In this large nationwide population, we still found higher major and minor ARs among people with diabetes compared with those without diabetes. However, AR and RR of major and minor LEAs in the diabetic compared with the nondiabetic population decreased significantly during the study period, confirming a positive trend that has been observed in smaller and regional studies in recent years.

This article discusses a research paper on the diagnosis and treatment of peripheral arterial vascular disease (PAVD), which references a study by Holger Lawall et al., published in a 2016 issue of the "Deutsches Ärzteblatt International", and mentions the future medical plan for PAVD.

A letter to the editor is presented in response to the article "Case Management Program for Patients With Chronic Heart Failure: Effectiveness in Terms of Mortality, Hospital Admissions and Costs" by Verena Hendricks in a 2014 issue along with the author's response to the same.

Objective The aim of this study was to investigate the 1-year safety and efficacy of a new iliac side-branched device (IBD) for revascularization of the hypogastric arteries. Methods Patients receiving the E-liac (Jotec GmbH, Hechingen, Germany) side-branched device at six German vascular centers either as a stand-alone procedure or in combination with abdominal aortic aneurysm exclusion were included in a prospectively created data bank. Collected data were analyzed for baseline characteristics, procedural events, and clinical follow-up; variables included endoleaks, reinterventions, and internal iliac artery (IIA) patency. Results Between January 2012 and January 2015, a total of 70 patients (69 men [98.6%]) with a median age of 74 years (range, 51-87 years) were consecutively treated; 66 patients had aneurysmatic disease of the iliac arteries, 2 patients had a para-anastomotic aneurysm after aortobi-iliac reconstruction, and another 2 patients had a type Ib endoleak after endovascular aneurysm repair. A total of 82 IIAs were revascularized, 12 bilaterally. Technical success was achieved in 100% (82/82) of the revascularized IIAs. All IBDs were patent at the end of the procedure. No instances of myocardial infarction, stroke, conversion to open repair, mesenteric or spinal cord infarction, or buttock necrosis were observed. There was one perioperative death (1.4%) in a 70-year-old patient with intraoperative gastrointestinal bleeding leading to multiple organ failure, which resulted in the patient's death on the fifth postoperative day. Within 30 days, one symptomatic occlusion of a treated common iliac artery (CIA) was observed. In two other patients, an asymptomatic kinking of the CIA segment of the IBD was revealed in the predischarge follow-up duplex ultrasound examination and corrected with relining. Median follow-up was 12 months (range, 6-16 months). One patient was lost during the follow-up period. Survival at 1 year was 98.5% with all IIAs remaining patent, whereas two CIA and two external iliac artery limb occlusions occurred. According to life-table analysis, the freedom from occlusion in a patient was 92% at 1 year, and freedom from type I endoleak was 87% at 1 year. Conclusions This first ever 1-year study reports the results with the new E-liac device and shows that it can be safely applied for the treatment of aortoiliac aneurysmatic disease with low reintervention rates and high patency rates. Long-term data are needed to confirm the durability of the device. [ABSTRACT FROM AUTHOR]
