a 55-year-old man referred for cardiac resynchronization therapy (crt) due to severe heart failure. a severe stenosis in the coronary sinus vein after the posterior branch disallowed the insertion of the lead. nevertheless, the stenosis was dilated and the left ventricle (lv) lead was implanted in the lateral marginal branch.

Background: Breast cancer is the most common type of malignancy in the female population, rarely is reported by thromboembolic events during the course of the disease. In this case, we present a rare case of breast cancer presenting as deep vein thrombosis of the axillary vein.Case Presentation: A 40-year- old female was admitted due to pain and swelling of her right arm and forearm of two mont...

Seasonal variation in the development of retinal vein occlusion in 1003 consecutive patients with various types of retinal vein occlusion was studied prospectively from 1973 to 1990. No seasonal variation in the onset of any type or combination of types of retinal vein occlusion was found. This refutes previous reports of such seasonal variation, which were based on small retrospective series.

Inducible NO synthase (iNOS) is expressed by macrophages and smooth muscle cells in atherosclerotic lesions. Previously, we have established a mouse model for vein graft arteriosclerosis by grafting autologous jugular veins or vena cava to carotid arteries. Using this model, we studied the role of iNOS in the development of vein graft arteriosclerosis in iNOS(-/-) mice. Four weeks after graftin...

A 4-day-old boy underwent an urgent operation for mixed total anomalous pulmonary venous connection with the left upper pulmonary vein draining into the innominate vein and the other pulmonary veins draining into the coronary sinus. The left upper pulmonary vein was left uncorrected at that time. After periodical follow-up for 5 years, repair of the uncorrected anomalous pulmonary vein was perf...

A Septic embolism is a type of embolism infected with bacteria containing pus. These may become dangerous if dislodged from their original location. Embolisms of this type in the azygos vein are potentially fatal. The diagnosis of septic azygos vein embolism is difficult, so rapid diagnosis and treatment is important to avoid complications. Generally, treatment is enough for appropriate antibio...

Previously we showed that a large number of endothelial cells in vein grafts undergo apoptosis or necrosis during the first few days followed by endothelial regeneration. In the present study, we investigated endothelial cell death and regeneration in vein grafts using transgenic mice carrying LacZ genes driven by an endothelial TIE2 promoter. When a vein fragment from TIE2-LacZ was isografted ...

Iatrogenic arteriovenous fistula (AVF) is usually caused by inappropriate blood vessel cannulation during diagnostic and interventional procedures [1–3]. Arteriovenous fistulas occur in 1.0–1.5% of cases following procedures with femoral access (FA) [1, 4, 5]. Iatrogenic fistulas are unintentional connections between an artery and a vein due to the needle being advanced too deeply and reaching ...

The purpose of this study was to report variations of the cubital superficial vein patterns in the Korean subjects, which was investigated by using venous illuminator, AccuVein. The 200 Korean subjects were randomly chosen from the patients and staff of the Keimyung University Dongsan Medical Center in Daegu, Korea. After excluding the inappropriate cases for detecting venous pattern, we collec...
