the use of diagnostic and therapeutic methods for assessing pulmonary vein due to its status as a main source of ectopic beats for the initiation of atrial dysrrythmias is strongly recommended.   we report the case of a 13-year-old girl who was admitted to our hospital with the electrocardiogram manifestation of an ectopic atrial tachycardia. the focus of arrhythmia was inside the right upper p...

the article reports a clinical case of a 39-year-old male patient who was admitted in the emergency room in shock. the clinical exams and additional tests identified a right massive hemothorax, without apparent etiological factors. he was submitted to an emergency right thoracotomy. a bulky varicose formation in the diaphragmatic surface, with evident laceration and haemorrhage was identified. ...

Essential thrombocythemia is a chronic myeloproliferative disorder characterized by a sustained proliferation of megakaryocytes, which leads to increased numbers of circulating platelets. Hemorrhagic and/or thrombotic episodes are frequent, and thrombosis of both veins and arteries may develop. Vessels in unusual sites may be involved, e.g., the hepatic veins, mesenteric veins, and the dig...

Lewis, D. A., M. P. Bracamonte, K. S. Rud, and V. M. Miller. Selected Contribution: Effects of sex and ovariectomy on responses to platelets in porcine femoral veins. J Appl Physiol 91: 2823–2830, 2001.—Estrogen replacement increases risk of venous thrombosis. In this study, we determined responses in vitro to platelets and platelet products in veins from adult male and intact and ovariectomize...

OBJECTIVE To compare the performance on the detection of the invisible veins between our modified prototype device and an existing device in elderly hospitalized patients. METHODS A prospective, cross-sectional, and observational study was performed in the invisible veins in elderly patients. The major variables, skin color near the invisible veins, and diameter and depth of the invisible vei...

Varicose veins are a common disorder and occur in about 40% of men and 32% of women. However the prevalence of the varicose veins has variability according to the age, gender, duration of reflux, and localization (superficial and/or deep veins). According to the Bonn Vein Study according to the duration of reflux (>500 ms) prevalence of the varicose veins in all veins was 35.3% (superficial vei...

In this investigation, 25 adult New Zealand White rabbits randomly selected from both sexes and studied.Coloured latex injection and corrosion cast methods were applied on the materials. This study was carried out to disclose the distribution of the cardiac veins of the New Zealand White rabbits. The veins that drain the heart were found to be the great cardiac vein, the middle cardiac vein, th...

Venography furnishes a map of the otherwise invisible deep veins of the extremities, discloses pathological changes, localizes the communicating veins, and tests the function of veins and valves. This clinical study, was carried out to evaluate the serial retrograde venography of the lower extremities with varicose veins, using the serial long film changer with a tilt. Forty-three extremities w...

Background: Proton induced X-ray emission (PIXE) has been applied as reliable and improved techniques in this study to compare concentration of various trace elements in normal and abnormal varicose veins. Materials and Methods: Five samples from normal veins and 13 samples from varicose veins bombarded by 2.0 MeV energy proton beams produced by a Van de Graff accelerator in vacuum. T...
