Pre-existing peripheral arterial disease in trauma

Area of Science:

• Vascular Surgery
• Trauma Surgery
• Geriatric Medicine

Background:

• Patients with peripheral artery disease (PAD) exhibit accelerated physiological aging.
• Vascular disease in one system often coexists with disease in other critical areas like the heart and brain.
• Comorbidities such as pulmonary and renal dysfunction are common in PAD patients.

Purpose of the Study:

• To highlight the unique challenges and increased risks faced by patients with PAD undergoing trauma.
• To emphasize the potential for thrombosis due to hypotension in stenotic vessels.
• To discuss surgical and management considerations for injured lower extremities in PAD patients.

Main Methods:

• Review of clinical presentations and management strategies for trauma in PAD patients.
• Analysis of physiological aging and systemic vascular disease prevalence.
• Evaluation of complications and outcomes associated with trauma in this cohort.

Main Results:

• PAD patients are physiologically older, increasing surgical complexity.
• Hypotension during trauma can induce thrombosis in stenotic vessels.
• Direct reconstruction of injured diseased vessels may be challenging, necessitating bypass or amputation.
• These patients face a higher incidence of complications and mortality, requiring prolonged ICU monitoring.

Conclusions:

• Trauma management in PAD patients requires specialized consideration due to physiological aging and systemic vascular disease.
• Early amputation may be the safest option for severely injured lower extremities.
• Vigilant intensive care unit monitoring is crucial for at least 2-3 days post-trauma to manage increased complication rates.
