The authors present the results of clinicoroentgenological and immunological investigations of the state of lower limb soft tissues in 117 patients with diabetes mellitus. Vascular wall calcification and soft tissue edema were noted practically in all the patients with a period of disease over 1 year. X-ray investigation permitted the detection of vascular lesion at early stages of complication development, in most of the patients even at the preclinical stage. A degree of lower limb vascular lesion is not related to a type of diabetes mellitus and the patients' age. There is direct correlation between the affection of the walls of medium size vessels and vessels of the fundus of the eye. The frequency and severity of lower limb vascular lesion, polyneuropathy and nephropathy grow significantly with an increase in a period of disease. A parallel decrease of immunoglobulins is noted. The affection of osseous tissue does not depend on a period of disease and shows insignificant correlation with a degree of vascular lesion.

A case report of gastric antral vascular ectasia treated by endoscopic band ligation combined with lauromacrogol injection.

Rationale: Gastric antral vascular ectasia (GAVE) is a rare acquired lesion characterized by vascular dilation in the gastric antrum, frequently results in occult or overt gastrointestinal bleeding. Endoscopic intervention remains the cornerstone of therapy. Argon plasma coagulation was previously considered a first treatment option.

Purpose: Treatment of peripheral artery disease (PAD) in the region below the knee (BTK) is dissatisfying as failure of treated target lesions (TLF) is frequent and diagnostic imaging is often challenging. In the BTK-region metallic drug-eluting stents (mDES) yielded best results concerning primary patency (PP), but also annihilate signal in magnetic resonance angiography (MR-A). A recently introduced non-metallic drug eluting bioresorbable Tyrocore® vascular scaffold (deBVS), that offers an option for re-treatment of lesions due to its full degradation within 3-4 years after placement, was investigated with respect to its compatibility with MR-A to unimpededly depict previously treated target lesions.

This first-in-man (FIM) study evaluated the feasibility and safety of a new peripheral plaque atherectomy system in patients with symptomatic lower extremity artery disease (LEAD). Ten patients with symptomatic LEAD (Rutherford class 2-5) were enrolled in a prospective, single-center study from March to April 2024. Patients aged 18-85 years with target lesions showing ≥70% stenosis and reference vessel diameters ≥1.

Acute myocardial infarction (AMI) is associated with well-established metabolic risk factors, especially hyperlipidemia and obesity. Myocardial ischemia-reperfusion injury (mIRI) significantly offsets the therapeutic efficacy of revascularization. Previous studies indicated that disrupted lipid homeostasis can lead to lipid peroxidation damage and inflammation, yet the underlying mechanisms remain unclear.

Alveolar echinococcosis (AE) is an infrequent zoonosis caused by Echinococcus multilocularis with a high degree of disability and mortality. Metastatic cerebral alveolar echinococcosis (CAE) is very rare and the lesions could lead to severe perilesional brain edema (PLBE) and subsequent uncontrollable intracranial hypertension. In this study, we sought to determine the expression of edema-associated factors in CAE lesions and their associations with PLBE.
