Tardieu Spots occur due to pressure of blood rupturing vessels in dependent areas. When is that observed?

• A. 24-36 hours postmortem
• B. 12-24 hours postmortem
• C. 4-6 hours postmortem
• D. 8-12 hours postmortem

Answer: (D)

Tardieu spots arise from rupture of tiny vessels in dependent areas as pooled blood from postmortem lividity creates pressure. This occurs during the early phase of livor mortis, when blood begins to pool and gravity pulls it into the lower parts, stressing the capillaries enough to produce small hemorrhages. The classic window for observing these punctate hemorrhages is about 8–12 hours after death, which is when lividity is forming but not yet fully fixed. Beyond this window, fixation of livor mortis reduces movement and the visibility of new Tardieu spots, and earlier time points may not show well-developed spots.
