Characteristics of spectra of superior vena cava flow Doppler velocities in pulmonary arterial hypertension
The Ecs were collected from nonthrombotic superior vena cava and iliac veins by enzymolysis and studied by flow cytometer to detect the positive rate of apoptosis.
If superior vena caval obstruction lies above the azygosvein, it acts as a bypass collateral to the right atrium.
The sinoatrial node is located at the junction of the superior vena cava and the right atrium.
The superior vena cava returns deoxygenated blood from the upper body to the right atrium, and it enters the upper portion of this chamber.
The study of relationship between urinary bladder pressure,superior vena caval pressure,inferior vena cava pressure and intra abdomninal pressure
Catheter tip placement positioned as follows:superior vena cava(20 cases), subclavicular vein(12 cases), right atrium(2 cases), jugular vein(4 cases), axillary vein(3 csese).
MethodPICC was inserted from the cubital fossa, and the superior vena cava was at the end of the deep venous remote.
Objective to study the rule of respiratory changes of flow parameters of superior vena cava when right atrium pressure increased.
Objective To explore the findings and clinical value of bedside ultrasonography in superior vena cava (SVC) syndrome in children after cardiac operations for congenital heart disease.
Objective To consecutively investigate the changes of the superior vena cava flow Doppler patterns in patients with superior vena cava syndrome (SVCS) and predict SVCS development.
Combined treatment of superior vena cava syndrome from lung cancer
