RESUMEN
Infective native aneurysms (INA) of the infrapopliteal arteries are rare and have previously been poorly described. This systematic review aims to provide an overview of the literature of this entity. Furthermore, two case reports of our own clinical experience are presented. PubMed, ScienceDirect, Cochrane, Ovid Embase, Ovid MEDLINE, and Web of Science were searched for articles on INAs of the infrapopliteal segment from January 1990 to September 2023. Article screening and selection were performed adhering to PRISMA guidelines. A total of 98 articles were screened and 20 were eligible for inclusion, of which all were case reports. In total, 22 patients with 28 infrapopliteal INAs were identified. The majority of INAs were located in the tibioperoneal trunk (n = 10, 36%) followed by the posterior tibial artery (n = 7, 25%). A current, or history of, infective endocarditis (IE) was described in 18 out of 22 patients (82%). Two patients died during hospitalization and one patient required a transfemoral amputation. A conservative antibiotic-only approach was chosen in three out of 28 INAs, two of which were the case reports described in this article; surgical or endovascular intervention was performed in 19 out of 28 aneurysms. No complications occurred in the conservative group, but one complication (transfemoral amputation) occurred in the interventional group. Infrapopliteal INA is a rare entity, and most described cases are precipitated by IE. Surgery or endovascular treatment might be indicated, but more research is warranted to define which patient would benefit and by what surgical approach.

INTRODUCTION: Diabetes Mellitus (DM) is a common chronic disease, affecting 435 million people globally. Impaired vasculature in DM patients leads to complications like lower extremity arterial disease (LEAD) and foot ulcers, often resulting in amputations. DM causes additional peripheral neuropathy leading to multifactorial wound problems. Current diagnostics often deem unreliable, but Near-Infrared Fluorescence with Indocyanine Green (ICG NIR) can be used to assess the foot perfusion. Therefore, this study explores DM's impact on foot perfusion using ICG NIR. METHODS: Baseline ICG NIR fluorescence imaging was performed in LEAD patients with and without DM. Ten perfusion parameters were extracted and analyzed to assess differences in perfusion patterns. RESULTS: Among 109 patients (122 limbs) of the included patients, 32.8 % had DM. Six of ten perfusion parameters, mainly inflow-related, differed significantly between DM and non-DM patients (p-values 0.007-0.039). Fontaine stage 4 DM patients had the highest in- and outflow values, with seven parameters significantly higher (p-values 0.004-0.035). CONCLUSION: DM is associated with increased in- and outflow parameters. Patients with- and without DM should not be compared directly due to different vascular pathophysiology and multifactorial wound problems in DM patients. Quantified ICG NIR fluorescence imaging offers additional insight into the effect of DM on foot perfusion.
