OBJECTIVE Persistence of the left superior vena cava (PLSVC) is a congenital anomaly resulting from failure of degeneration of the left cardinal vein. The prevalence of this anatomical variant is approximately 0.3% in the general population. The aim of this study was to determine the prevalence of the persistence of the left superior vena cava in order to avoid potential complications. SUBJEC...

An area of increased activity in segment IV of liver (quadrate lobe) on 99mTc-sulfur colloid (TSC) scans has been well documented in patients with superior vena cava obstruction. Similarly intense enhancement of the quadrate lobe in the arterial phase may be seen on computed tomography in patients of superior vena cava syndrome. We present this imaging finding in a case of malignant thymoma cau...

A 41-year-old man presented with dizziness associated with sinus bradycardia and sinus arrest. An attempt to implant a transvenous pacing lead was frustrated by absence of the right superior vena cava. The left superior vena cava persisted and drained via the coronary sinus into the right atrium. Absence of the right superior vena cava may present with symptomatic sinus node dysfunction and may...

Stenting of the central veins is well established for treating localized venous stenosis. The techniques regarding catheter preservation for central venous catheters in the superior vena cava have been described. We describe here a method for stent implantation in the superior vena cava and the left brachiocephalic vein, and principally via a single jugular venous puncture, while saving a left ...

During the routine dissection of a cadaver a left superior vena cava was noticed passing into the coronary sinus. This condition is not uncommon, but further dissection showed that the coronary sinus ended 1 cm. from the wall of the right atrium. Inspection of the right atrium showed no opening for the coronary sinus and the wall between the opening for the inferior vena cava and the tricuspid ...

To reduce the possibility of cardiac tamponade, a rare but lethal complication of central venous catheters, the tip of the central venous catheter should be located above the cephalic limit of the pericardial reflection, not only above the superior vena cava-right atrium junction. This study was performed to measure the superior vena cava lengths above and below the pericardial reflection in ca...

The superior vena cava is formed by the union of the right and left brachiocephalic veins. It is located in the middle mediastinum, to the right of the aorta and anterior to the trachea. Superior vena cava syndrome consists of a group of signs (dilation of the veins in the neck, facial swelling, edema of the upper limbs, and cyanosis) and symptoms (headache, dyspnea, cough, orthopnea and dyspha...

OBJECTIVE Surgical treatment of anomalous pulmonary venous connection to the superior vena cava, associated with sinus venous atrial septal defect, is well established and correlates with low mortality and morbidity. In order to reduce the incidence of stenosis or occlusion of the right superior vena cava, especially when associated with the presence of left superior vena cava, the right atrial...
