middle hepatic vein
vessel that runs in the main lobar fissure; vein that divides right and left lobes
right portal vein
supplies the right lobe of the liver; branches into anterior and posterior segments
left portal vein (horizontal segment)
vein that separates caudate lobe from medial segment of left lobe
along with falciform ligament, it divides medial and lateral segments of the left lobe of liver; recanalizes in cirrhosis
separates the lt lobe from the caudate lobe; , Continuos with the teres/round ligament; a fibrous remnant of the fetal ductus venosus
sonography of acute hepatitis
sonographic features: hypoechoic liver parenchyma, liver enlargement, hyperechoic portal vein walls
sonography of chronic hepatitis
sonographic features: hyperechoic liver parenchyma, small liver, decreased echogenicity of portal vein walls
pyogenic abcess (bacterial)
sonographic features: complex mass, echogenic Gas, reverberation artifact
Echinococcal cyst (hydatid disease)
simple cyst to complex massappearance, may have water lily sign, daughter cysts are common; sheep; casoni skin test to diagnose
parasitic infection; intrahepatic portal veins occlude resulting in portal hypertension (cuz of eggs)
renal artery stenosis diagnostic criteria
renal artery/ aorta ratio (RAR) > 3.5;
>3.5 means there is at least 60% narrowing
spermatoceles or epididymal cysts
occurs in epididymal head, anechoic, well defined; both can result from prior episodes of epididymitis
SMA doppler in postprandial state
doppler waveform is low resistance, increased velocity after eating
disorder of the thyroid gland characterized by the presence of hyperthyroidism, goiter, and exophthalmos
thyroid artery supply
superior (branch from ECA) and inferior (branch from thyrocervical trunk) thyroid arteries
thyroid venous supply
superior, middle drain into IVC, inferior thryoid vein drains into inominate vein
results from a defect in hte main artery wall, eg post catheter insertion. Must be a channel communication from main artery to pulsatile structure outside vessel walls.
involve all three layers of the arterial wall and are best described as the weakening of the vessel wall. Can be fusiform and circumferential (most are) or saccular
sonographic criteria includes non compressible appendix, >6mm diameter, appendicolith (fecalith)
hypertrohic pyloric stenosis
neonatal patients(3-6wks) vomiting; criteria for diagnosis all will increase: pyloric muscle thickness, py channel length, py diameter
increase in blood pressure in the veins of the portal system caused by obstruction in the liver (often associated with alcoholic cirrhosis, now leading cause is hepatitis C), causing enlargement of the spleen and (portosystemic) collateral veins, ascites; portal vein size >13mm, pressure gradient normal is slightly higher than ivc; TIPS to lower portal pressure
an inflammation of the gallbladder that may occur as an acute or chronic process. Acute inflammation is associated with gallstones. Chronic condition of this results when inefficient bile emptying and gallbladder muscle wall disease causes a fibrotic and contracted gallbladder.
