The article presents an experience with the operative treatment of 476 patients with recurrent dilatation of superficial veins of lower extremities. True and false variants of the recurrences are discussed as well as problems of their diagnosis and treatment. Stress is made on high specific weight (87%) of patients with the development of recurrences due to incomplete examinations and technical defects during the first operation. In 13% of the patients recurrences were caused by progress of the varicose disease and non-eliminated hypertension in profound veins due to their ectasia and incompetence of the valves.

Introduction And Importance: A traumatic arteriovenous fistula (TAVF) is a vascular injury where an artery and a vein become abnormally connected. Although endovascular intervention is often the first choice for TAVF, some special cases still require open surgery.
Case Presentation: A 65-year-old man developed a chronic AVF in the lower superficial femoral artery (SFA) one year after a farming accident.

To measure the influence of ganglion cell layer (GCL) thickness on the changes in size and red blood cell (RBC) flow in small retinal vessels evoked by full-field flicker. We used a dual-beam adaptive optics scanning laser ophthalmoscope to image 11 healthy young controls in two retinal areas with significantly different GCL thicknesses. All capillaries and arterioles of the superficial vascular plexus were responsive to the flicker stimulation.

Background/objectives: Superficial esophageal cancer is diagnosed by evaluating the vascular architecture, including dilation, tortuosity, caliber change, and shape, of a lesion. However, this diagnosis is subjective and requires extensive experience. Endoscopically distinguishing squamous intraepithelial neoplasia (SIN) from esophageal cancer is difficult.

Background: Arteriovenous malformation (AVM) and developmental venous anomaly (DVA) rarely coexist. Developing a surgical strategy to treat this co-occurrence is difficult due to the unclear pathogenesis. We report the use of super-selective digital subtraction angiography (DSA) and Three-dimensional (3D) rotational digital subtraction venography (DSV) to develop a surgical strategy for complex AVM draining into a DVA.
