OBJECTIVES Autologous veins are preferred conduits in by-pass surgery. However, long-term results are hampered by limited patency due to intimal hyperplasia. Although mechanisms involved in development of intimal hyperplasia have been established, the role of inflammatory processes is still unclear. Here, we studied leukocyte recruitment and intimal hyperplasia in inferior vena cava grafts tran...

Persistent left cranial vena cava (PLCVC) is an uncommon congenital thoracic venous anomaly in dogs. This study examines the clinical and CT findings of dogs diagnosed with PLCVC incidentally. In this study, complete type of PLCVC was diagnosed in 26 dogs with CT angiography. Shih tzu (17 cases) and Pekingese dogs (3 cases) were overrepresented. There was no gender predisposition, and the avera...

Microangiography, using methylene blue injected at eight vitelline vein sites, was performed on 156 developing chick embryos at Hamburger-Hamilton stages 14-22. Two stream patterns were observed. Type A coursed sequentially through the dorsal portion of the sinus venosus, the cranial segments of the primitive atrium and atrioventricular canal, the ventral parts of the primitive ventricle and co...

Scimitar vein is the partial anomalous pulmonary venous connection usually draining lower pulmonary lobe to the inferior vena cava or right atrium. We present a scimitar vein anomaly in a 34-year-old woman with the uncommon association of a secundum type of atrial septal defect and atretic right upper pulmonary vein. She presented with increasing dyspnea for 2 months, however, she was asymptoma...

Recently, we established a new mouse model of vein graft arteriosclerosis through the grafting of vena cava to carotid arteries. In many respects, the morphological features of this murine vascular graft model resemble those of human venous bypass graft disease. With this model, we studied the role of intercellular adhesion molecule-1 (ICAM-1) in the development of vein graft arteriosclerosis i...

A randomised controlled study of photocoagulation compared with no treatment in central retinal vein occlusion is reported. Forty-eight patients were allocated into treated and control groups by a random procedure 3 months after their first visual symptoms. For the analysis they were subdivided into (1) ischaemic type, and (2) hyperpermeability-response macular-oedema type of central retinal ve...

PURPOSE To report the case of a 48-year-old man with unilateral central retinal vein occlusion. METHODS The clinical, hematologic and hypercoagulability evaluations of the patient were thoroughly and specifically carried out. RESULTS The central retinal vein occlusion was of nonischemic type and was associated with polyglobulia, hyperleukocytosis, hypercholesterolemia, multiple dental foci,...

BACKGROUND/AIM Hemodialysis catheter, as an integral part of hemodialysis, is a catheter placed into the jugular, subclav ian and femoral vein. The most common catheter-related complications are infections and thrombosis. The aim of the study was to analyze the prevalence of complications associated with differently inserted central-vein catheters for hemodialysis. METHODS The study was organ...
