Which condition would require an urgent referral to a vascular surgeon?

A condition that requires an urgent referral to a vascular surgeon is gangrene. Gangrene refers to the death of body tissue due to a lack of blood flow (ischemia) or a serious bacterial infection. This condition can lead to severe complications, including systemic infection, sepsis, and the need for limb amputation if not addressed promptly. The urgent nature of gangrene arises from the potential for rapid deterioration of the affected tissue and the significant risk posed to the patient’s overall health.

In contrast, minor infections, localized edema, and dry skin typically do not present the same level of urgency. While they may require medical attention, they generally do not indicate immediate vascular compromise or life-threatening conditions, making them less critical for prompt surgical intervention.
