Q

How does traumatic pericarditis cause cardiac tamponade?

A

Aorta and pericardial sac ruptured → blood filled pericardium → influx of fluid compresses the heart → heart can’t compensate leading to tamponade

Q

Cardiac tamponade pathogenesis

A

Q

Serous atrophy of fat

A

Malnourishment

Q

Visceral gout

A

Deposition of urates on visceral organs
Visceral (kidneys affected too) or articular
