[Puffy hand in long-term intravenous drug users]

Area of Science:

• Addiction Medicine
• Vascular Surgery
• Dermatology

Background:

• Narcotic addiction frequently leads to systemic and local complications, including venous thrombosis and septic emboli.
• The puffy hand sign is an uncommon complication observed in long-term intravenous drug users.

Observation:

• Three long-term intravenous drug users presented with bilateral, non-pitting hand edema, appearing years after cessation of heroin injection.
• Edema extended from the fingers to the wrist, and in one case, also affected the feet.
• Duplex ultrasound was normal, but lymphangiography suggested deep lymphatic destruction.

Findings:

• Puffy hand syndrome is likely caused by lymphatic obstruction due to repeated intravenous drug injections damaging lymphatic vessels.
• Buprenorphine, when misused intravenously due to its poor solubility, may contribute to lymphatic obstruction and the development of puffy hand syndrome.
• This condition is distinct from deep palmar space infections requiring surgical intervention.

Implications:

• Puffy hand syndrome represents a chronic complication of intravenous drug abuse with no current effective therapy.
• Accurate diagnosis is crucial to differentiate it from treatable conditions like deep palmar space infections.
• Understanding the role of specific drugs like buprenorphine in its pathogenesis may inform harm reduction strategies.
