Summary
Intraarterial injection of Methylphenidate (Ritalin) caused severe hand ischemia, leading to finger necrosis and amputation despite treatment. This highlights drug-induced extremity ischemia as a critical vascular emergency requiring immediate attention.
Area of Science:
- Vascular Surgery
- Pharmacology
- Emergency Medicine
Background:
- Intraarterial drug administration carries risks of vascular complications.
- Methylphenidate (Ritalin) is a central nervous system stimulant.
- Accidental intraarterial injections can lead to severe ischemia.
Observation:
- A 36-year-old patient experienced severe hand ischemia after injecting Methylphenidate into the radial artery.
- Vascular diagnostics revealed normal radial and ulnar artery perfusion but severe ischemia in the hand's small vessels.
Findings:
- Despite intraarterial lysis therapy, heparin anticoagulation, and prostaglandin infusions, the patient developed finger necrosis.
- Partial amputation was necessary, followed by successful wound healing.
Implications:
- Drug-induced extremity ischemia is a critical vascular emergency.
- Prompt diagnosis and intervention are crucial for limb salvage.
- Awareness of potential complications from intraarterial drug injections is vital for healthcare providers.
