Vascular Mod 8

Question 1

Normal size of the portal vein

Answer 1

< 1.3 cm

Question 2

Hepatopetal define

Answer 2

Portal vein flows into liver

Question 3

Cause of pulsatile portal vein

Answer 3

Tricuspid regurg

right heart failure

Question 4

Hepatic venous waveform

Answer 4

S = filling of RA during ventricular systole
V = RA overfilling just before tricuspid opens
D = filling of RA during ventricular diastole
A = RA contraction with reversed flow into liver

Question 5

Tricuspid regurg on hepatic venous waveform

Answer 5

Accentuated A wave

Question 6

Cirrhosis on hepatic venous waveform

Answer 6

loss of variations

Question 7

Collaterals of hepatic outflow

Answer 7

1) Gastroesophageal varices (coronary vein feeds esophageal varices
2) patent paraumbilical veins
3) splenorenal
4) retroperitoneal
5) pelvic veins
6) bowel

Question 8

Budd-chiari syndrome

Answer 8

Hepatic venous obstruction

Question 9

Normal velocity in TIPS

Answer 9

> 90 cm/s

Deep inspiration lowers velocity

Question 10

Abnormal velocity in TIPS

Answer 10

> 190 cm/s
< 50 cm/s
changes of 50 cm/s along stent
