central vein
the centrally placed drainage vessel of each hepatic lobule, receiving blood from the hepatic sinusoids.
central venous catheterization
insertion of an indwelling catheter into a central vein for the purpose of administering fluid and medications and for the measurement of central venous pressure (see below).
central venous pressure (CVP)
the pressure of blood in the right atrium, measured by an in situ catheter in the right atrium, is a much better guide of the degree of vasogenic peripheral failure than is arterial blood pressure. The technique is used mainly in dogs and cats.

This study has shown that the essential pathologic changes of the hepatic vasculature in patients with HHT are as follows: (1) focal sinusoidal ectasia, (2) abnormal direct communications between hepatic arteriolar branches and ectatic sinusoids (formation of A-V shunts), and (3) frequent and large communications between the portal and central veins through ectatic sinusoids (formation of P-V shunts).
