A fistula is an abnormal pathway between 2 anatomic spaces or a pathway that leads from an internal cavity or organ to the surface of the body. A sinus tract is an abnormal channel that originates or ends in one opening.
Pulmonary 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.
The Coronary Sinus
arteries are thicker then veins
Empties into coronoary sinus which empties into the right atrium
The difference is that venous thrombosis refers to a blood clot that forms in a vein and deep vein thrombosis is a clot that forms in the deep veins of a leg.

The superior sagittal sinus is a vein located in the dura mater that runs parallel to the longitudinal fissure of the brain. It collects blood and cerebrospinal fluid from the superior aspects of the brain and drains into the internal jugular vein.
To drain the tissues of the heart and empty into the coronary sinus
A vein is larger than a venule. It is also closer to the heart and farther from the capillaries than a venule.
You mean the great coronary vein and Marshall's vein? If so, then into the coronary sinus then to the right atrium through the valve of Thebesius!
A head scan looks primarily at the brain and a sinus scan looks only at the sinuses in the face region.
