| Draining area | Upper half of the body (above the diaphragm) |

Does the coronary sinus drain into the superior vena cava?
At times, the coronary sinus can be obliterated or absent. In that case, the cardiac veins drain into the superior vena cava or left brachiocephalic vein via the oblique vein of Marshall. Rarely, the coronary sinus may drain into the left atrium, causing a left-to-right shunt.
Where does the left superior intercostal vein drain into?
left brachiocephalic vein
The left superior intercostal vein forms by the union of the 2nd to 4th left posterior intercostal veins. It courses superiorly to the left of the midline, arches posteriorly lateral to the aortic arch to drain into the left brachiocephalic vein.
What does the superior vena cava branch into?
The right and left innominate veins terminate in the superior vena cava, which opens into the upper posterior portion of the right atrium.
Which veins drain into the inferior vena cava?
Hepatic veins It is formed near the anteroinferior aspect of the liver and enters the inferior vena cava near the upper border of the caudate lobe. The other two main veins, the middle and left hepatic veins, usually drain into the inferior vena cava as a common trunk.
What is left sided superior vena cava?
Background. Persistent left superior vena cava (PLSVC) is a rare vascular anomaly that begins at the junction of the left subclavian and internal jugular veins, passes through the left side of the mediastinum adjacent to the arcus aorta. It mostly drains into the right atrium via the coronary sinus (CS).
What does superior vena cava drain?
It is formed by the union of the right and left brachiocephalic veins – which provide venous drainage of the head, neck, and upper limbs. At the level of T4, the superior vena cava receives the azygous vein, which drains the upper lumbar region and thoracic wall.
What is double SVC?
Duplication of superior vena cava (SVC) is a rare anomaly. The incidence of double SVC in general population is 0.3% whereas in patients with congenital heart disease it varies between 10-11%. Double SVC cases have clinical importance if especially the one on the left side drains into the left atrium.
How many superior vena cava are there?
two
The vena cava has two parts: the superior vena cava and the inferior vena cava. The superior vena cava carries blood from the head, neck, arms, and chest. The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.
Which does not drain into the coronary sinus quizlet?
What cardiac veins do not drain into the coronary sinus? Anterior cardiac veins and the Thebesian veins.

The posterior intercostal veins drain into the azygos (right side) and hemiazygos and accessory hemiazygos vein (left side).
Where does the vena cava drain?
The inferior vena cava is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart….

| Drains to | Right atrium |
| Artery | abdominal aorta |
What does the superior vena cava drain?
Function. The superior vena cava is a vital structure in the human circulatory system that helps drain large amounts of deoxygenated blood from the head, eyes, neck, and upper limbs into the upper left chamber (atrium) of the heart.
Which vessels drain into the vena cava?
Tributaries of the inferior vena cava
- Lumbar veins.
- Right gonadal vein.
- Renal veins.
- Right suprarenal vein.
- Inferior phrenic veins.
- Hepatic veins.
- Common iliac veins.
What is coronary sinus?
The coronary sinus is the major venous tributary of the greater cardiac venous system; it is responsible for draining most of the deoxygenated blood leaving the myocardium.
What goes into superior vena cava?
Your right and left innominate (or brachiocephalic) veins merge to form your superior vena cava. Your superior vena cava is next to the right side of your sternum and goes into your right atrium, where all the oxygen-poor blood goes.
