Where are the intercostal veins located?
The intercostal veins are a group of veins which drain the area between the ribs (“costae”), called the intercostal space. Posterior intercost veins that drain into the Superior intercostal vein – 2nd, 3rd, and 4th intercostal spaces. The superior intercostal vein then drains into the Azygous vein.
Where is the intercostal nerve artery and vein located?
costal groove
The intercostal artery, vein, and nerve run along the inferior aspect of each rib, occasionally running underneath a ledge in the costal groove.
How many intercostal veins do we have?
An easy way to remember this is to learn the mnemonic VAN (from superior to inferior: Vein, Artery and Nerve). Each space contains one posterior and two anterior intercostal veins which runs with the arteries of the same name.
Where do the intercostal veins come from?
The anterior intercostal veins originate from the intercostal space just inferior to anterior aspects of their respective ribs and drain into the internal thoracic and musculophrenic veins.
Where does the first intercostal vein drain into?
brachiocephalic vein
The 1st posterior intercostal vein, supreme intercostal vein, drains into the brachiocephalic vein or the vertebral vein.
Where is the main intercostal neurovascular bundle located?
The neurovascular bundle, located in the costal groove in the undersurface of each rib, between the internal intercostal muscle and innermost intercostal muscle, supplies much of the innervation and vascular supply to the thoracic wall.
How do you feel intercostal spaces?
From the angle of Louis, move your fingers to the right and you will feel a gap between the ribs. This gap is the 2nd Intercostal space. From this position, run your fingers downward across the next rib, and the next one. The space you are in is the 4th intercostal space.
Where is the first intercostal space?
The intercostal space (ICS) is the anatomic space between two ribs (Lat. costa). Since there are 12 ribs on each side, there are 11 intercostal spaces, each numbered for the rib superior to it….

What is the supreme intercostal artery?
The supreme intercostal arteries, or superior intercostal arteries, are formed as a direct result of the embryological development of the intersegmental arteries. These arteries are paired structures of the upper thorax which normally form to provide blood flow to the first and second posterior intercostal arteries.
What do the intercostal veins connected to?
The posterior intercostal veins are veins that drain the intercostal spaces posteriorly. They run with their corresponding posterior intercostal artery on the underside of the rib, the vein superior to the artery….

How do you treat intercostal neuralgia?
Treatments include:
- Intercostal nerve blocks, which are injections of a local anesthetic or a corticosteroid around the affected intercostal nerve.
- Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin) naproxen (Naprosyn, Aleve), and indomethacin (Indocin).
Can you feel the first intercostal space?
Anteriorly, the first rib cannot be palpated below the clavicle, but the first intercostal space may be felt above the second rib. The position of the second rib is a reliable landmark anteriorly for determining the position of other ribs: palpate down the manubrium to the manubrio-sternal junction.
