Episode Details

This episode explains why a "black toe" is usually a sign of systemic vascular failure and breaks down the three main causes—chronic digital ischemia, acute arterial embolism, and blue-toe (cholesterol) syndrome—covering how each presents, key distinguishing features, essential diagnostic tests, and immediate management steps.

Takeaway actions include calling vascular early, avoiding premature amputation, initiating urgent anticoagulation for embolism when indicated, providing supportive care for cholesterol emboli, and preventing future events through diabetes control, smoking cessation, lipid management, and careful vascular intervention.
