  2. Superior vena cava syndrome - Wikipedia

    en.wikipedia.org/wiki/Superior_vena_cava_syndrome

    Superior vena cava syndrome (SVCS), is a group of symptoms caused by obstruction of the superior vena cava ("SVC"), a short, wide vessel carrying circulating blood into the heart. The majority of cases are caused by malignant tumors within the mediastinum , most commonly lung cancer and non-Hodgkin's lymphoma , directly compressing or invading ...

    Non-developmental syndromes also directly or indirectly affect the Great Cerebral Vein of Galen, although they are extremely rare. These include superior vena cava syndrome (SVCS), and thrombosis of the lateral sinus, superior sagittal sinus, internal jugular vein, or of the Great Cerebral Vein of Galen itself.

  4. Hypoplastic right heart syndrome - Wikipedia

    en.wikipedia.org/wiki/Hypoplastic_right_heart...

    Hypoplastic right heart syndrome is both less common and less severe than hypoplastic left heart syndrome. Within the United States it occurs in 1 in 60,000 births, [2] as opposed to HLHS, which occurs in 1 in 4,300 births. [3] [1] [11] HRHS requires prenatal diagnosis since it often necessitates immediate and emergency treatment. Pregnant ...

  5. Superior vena cava - Wikipedia

    en.wikipedia.org/wiki/Superior_vena_cava

    The superior vena cava (SVC) is the superior of the two venae cavae, the great venous trunks that return deoxygenated blood from the systemic circulation to the right atrium of the heart. It is a large-diameter (24 mm) short length vein that receives venous return from the upper half of the body, above the diaphragm .

  6. Pancoast tumor - Wikipedia

    en.wikipedia.org/wiki/Pancoast_tumor

    If obstruction of the superior vena cava by the Pancoast tumor occurs, a resulting mass effect called the superior vena cava syndrome occurs, resulting in facial swelling cyanosis and dilatation of the veins of the head and neck. This syndrome can be seen in 5-10% of patient cases. [11]

  7. Persistent left superior vena cava - Wikipedia

    en.wikipedia.org/wiki/Persistent_left_superior...

    The left superior vena cava is not shown in this image. In anatomy , a persistent left superior vena cava is the most common variation of the thoracic venous system . [ 1 ] [ 2 ] It is present in between 0.3% and 0.5% of the population, [ 3 ] [ 4 ] [ 5 ] and is an embryologic remnant that results from a failure to involute .

  8. Congenital stenosis of vena cava - Wikipedia

    en.wikipedia.org/wiki/Congenital_stenosis_of...

    Congenital stenosis of vena cava is a congenital anomaly in which the superior vena cava or inferior vena cava has an aberrant interruption or coarctation. In some cases, it can be asymptomatic, [ 1 ] and in other cases it can lead to fluid accumulation and cardiopulmonary collapse.

  9. Raghib syndrome - Wikipedia

    en.wikipedia.org/wiki/Raghib_Syndrome

    If this vein fails to disappear, the persistent left superior vena cava will form. [13] This anomaly is present in between 0.3% and 0.5% of the population and roughly 2.1% to 4.3% of those with congenital heart disease. [3] Usually babies who experience the persistence of a left superior vena cava display other heart anomalies as well. [13]
