The procedure involves injecting the right or left portal vein with embolic material to occlude portal blood flow.
A dilated portal vein (diameter of greater than 13 or 15 mm) is a sign of portal hypertension, with a sensitivity estimated at 12.5% or 40%. On Doppler ultrasonography, a slow velocity of <16 cm/s in addition to dilatation in the main portal vein are diagnostic of portal hypertension.

sinh, cosh and tanh csch, sech and coth. There are various equivalent ways to define the hyperbolic functions. Exponential definitions sinh x is half the difference of e x and e −x cosh x is the average of e x and e −x. In terms of the exponential function: Hyperbolic sine: the odd part of the exponential function, that is,
