Authors studied changes of femoral vein developed by the effect of examinations experimental lymphoedema in dogs. Light and electronmicroscopic were performed from femoral vein of animals killed on 3rd and 14th postoperative day, and biomechanical examinations were done too from dogs killed on 14th postoperative day. In vessel wall edema, fibrosis, and in valves infiltration consisting of macrophages, neutrophilic granulocytes and of mesenchymal cells were observed. Biomechanical examinations did not show significant deviation. Their results suggest the possibility that extremital lymphoedema also in man may contribute to development of varicosity or to its aggravation. Experimental lymphoedema of lower limb of dog can be proposed as model experiment to the complex study of pathogenesis of development of varix.

Background: Hydrogen sulfide (HS) is a widely studied gasotransmitter, and its protective effect against ischemia-reperfusion damage has been explored in several studies. Therefore, a requirement exists for a comprehensive study about HS effects on ischemia-reperfusion damage in flap surgery. The aim of this study is to examine the effect of hydrogen sulfide by creating ischemia-reperfusion injury in the vascular-stemmed island flap prepared from the rat groin area.

Introduction: Electrophysiologic (EP) procedures are typically performed via the femoral venous system, but in some patients, the inferior vena cava (IVC) is unavailable. The hepatic vein has emerged as a viable alternative to femoral access, providing an inferior route that accommodates large sheaths required for better catheter manipulation. Although the percutaneous transhepatic approach has been used successfully in the pediatric population, its use in adults is scarce, with a complication rate of approximately 5%.

Traumatic hemorrhage and infection are major causes of mortality in wounds caused by battlefield injuries, hospital procedures, and traffic accidents. Developing a multifunctional nano-drug capable of simultaneously controlling bleeding, preventing infection, and promoting wound healing is critical. This study aimed to design and evaluate a nanoparticle-based solution to address these challenges effectively.
