Slide 1:
Subcutaneous edema, equine |
 |
Slide 2:
Edema pits on pressure |
 |
Slide 3:
Pulmonary hyperemia and edema (early pneumonia) |
 |
Slide 4:
Chronic passive hepatic congestion secondary to right cardiac failure |
 |
Slide 5:
Acute passive centrilobular hepatic congestion |
 |
Slide 6:
Acute glomerular hyperemia (acute glomerulonephritis) |
 |
Slide 7:
Hypostatic pulmonary congestion, equine |
 |
Slide 8:
Infarct of hand with gangrenous necrosis |
 |
Slide 9: Petechial hemorrhages (Herpes virus, canine kidney) |
 |
Slide 10: Pale renal infarct, surrounded by hyperemic border |
 |
Slide 11: Hemorrhagic pulmonary infarct, feline |
 |
Slide 12: Hemorrhagic infarction of the jejunum |
 |
Slide 13:
Hemorrhagic cerebral infarct |
 |
Slide 14: Myocardial infarct at 48 hours.
Nitro-blue-tetrazolium stain. Infarcted tissue is pale. |
 |
Slide 15:
Myocardial infarct at 10 days. A border of hyperemic
granulation tissue surrounds the infarct. |
 |
Slide 16:
Healed myocardial infarct. Collagen stains blue.
|
 |
Slide 17: Rupture of the interventricular septum in an infarcted heart at 6 days |
 |
Slide 18: A large, recent, pulmonary thrombo-embolus |
 |
Slide 19: A septic pulmonary
thrombo-embolus. Note bacterial colonies
and the lines of Zahn. |
 |
Slide 20: Aortic atherosclerotic plaques |
 |
Slide 21:
Coronary atherosclerotic plaque. The intima consists of a thick fibrous
capsule overlying a lipid core. Frozen section, oil red O stain |
 |
Slide 22:
A mature coronary artery atherosclerotic plaque. The intima is more than 4 times the thickness of the media and consists of a fibrous
capsule overlying a central core of necrosis and cholesterol clefts. |
 |
Slide 23:
Cross section of a coronary artery. A thrombus occludes the lumen and
rests upon a mature atherosclerotic plaque. Note the relative
thickness’ of the intima and media. |
