I know this is caused by pressure on the heart which is inhibiting the right atrium to empty into the ventricle.
But i am uncertain on the cause of the actual vessel distention. My best guess would be that the heart is struggling to pump blood out so the aorta and other major arteries dilate to increase blood flow. This on top of the air pressure accumulating in the plural space from the tension pneumo is my best guess. However i could be wrong. Hope this helped.

subclavian vein
AnswerIt's called the carotid vein. Veins carry blood towards the heart and arteries carry it away. The vein that carries deoxygenated blood to the heart from the upper body is called the superior vena cava and the vein that carries blood from the head to that vein through the neck is the jugular vein.
The internal jugular vein is formed from the sigmoid sinus (after receiving the lesser petrosal sinus) just after passing through the jugular foramen to become the internal jugular vein.
An expansion of the aortic vein
In humans there is one external and one internal jugular vein. The internal jugular vein is much larger (about twice the diameter) of the external jugular. In the cat there are a pair of each vein but the external jugular vein is about twce as large as the internal. (Opposite of humans.)
