CELL INJURY
44. A 59-year-old man undergoes repair of an abdominal aortic aneurysm. During the procedure the distal abdominal aorta is clamped, occluding blood supply to the legs for 45 minutes. The period of ischemia is short enough that no permanent damage is done to the affected tissues. Examination of tissue obtained on biopsy of the gastrocnemius muscle at the end of the period of ischemia is most likely to show
A) coagulation necrosis
B) erythrophagocytosis
C) hydropic swelling
D) karyolysis
E) karyorrhexis
