A large mass in the popliteal fossa was found to be a leiomyoma of the popliteal vein with portions of tumour both inside and outside the vein. This is only the second recorded case of a benign smooth muscle tumour of a peripheral vein.

PURPOSE To investigate the reliability of intra-atrial electrocardiogram (ECG) use for external jugular vein (EJV) catheterization. MATERIALS AND METHODS Patients undergoing open heart surgery in Suleyman Demirel University Hospital between February and June 2006 were included in the study. Using a sterile Seldinger technique, a triple lumen polyurethane central venous catheter was introduced...

Importance Fetal umbilical vein aneurysm is an uncommon anomaly that accounts for approximately 4% of umbilical cord abnormalities. The rate of intrauterine fetal death is reported to be approximately 4% to 5%, higher than the background rate of 0.7% that is generally reported during pregnancy. Objective The aim of this study was to review the pathophysiology, diagnosis, and clinical manageme...

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare hematologic disorder that manifests with hemolytic anemia, thrombosis, and peripheral blood cytopenias.Acute abdominal pain is one of the PNH clinical manifestations due to venous thrombosis of intra-abdominal sites including hepatic, portal, mesenteric, and splenic veins.Eculizumaband allogeneic bone marrow transplantation (BMT) arethe only w...

Hepatic vein outflow obstruction induces remarkable changes of intra-hepatic blood circulation; the significance of these changes remains uncertain. Six patients with obstruction of the hepatic veins were evaluated by duplex Doppler ultrasound and computed tomography. The adaptive changes secondary to obstruction were analyzed and their significance was correlated with the clinical findings. Fo...

Recent investigations of the birth changes in the foetal circulation indicate that certain channels, namely, the ductus arteriosus, ductus venosus and extra-abdominal umbilical vessels, are quickly closed by the contraction of their muscular walls (Barclay, Franklin and Prichard, 1944). This immediate functional closure is followed by an anatomical obliteration which takes place during the firs...

We compared effects of the antiarrhythmic drug bepridil on the electrophysiological parameters in the isolated pulmonary vein preparation from guinea pigs with those in the left atrium. Three pairs of bipolar electrodes were attached to the left atrium, pulmonary vein and junctional region of left atrium and pulmonary vein to measure intra-atrial and intra-pulmonary vein conduction velocity and...
