[Drug-induced acute arterial occlusion]

Area of Science:

• Vascular Medicine
• Pharmacology
• Toxicology

Context:

• Acute limb ischemia typically results from mechanical vascular obstruction.
• Drug-induced ischemia, excluding erroneous intra-arterial injections, is clinically rare.
• Ergotamine derivatives are known vasoconstrictors with potential for adverse vascular events.

Purpose:

• To report a rare case of acute limb ischemia in a young woman.
• To investigate the potential link between methylergometrine use and ischemic events.
• To highlight the diagnostic and therapeutic considerations for drug-induced vascular complications.

Summary:

• A young woman presented with acute ischemia of both lower limbs.
• Her medical history included liver insufficiency and methylergometrine (Methergin) treatment for uterine stimulation post-spontaneous abortion.
• The clinical presentation suggested a drug-induced ischemia due to an ergotamine derivative, confirmed by rapid recovery after chlorpromazine and nifedipine administration.

Impact:

• This case underscores the importance of considering medication side effects in unexplained acute ischemia.
• It highlights the potential for ergotamine derivatives to cause severe peripheral ischemia.
• The successful treatment suggests a therapeutic approach for this rare complication, though further studies are needed.
