A young adult with internal carotid artery occlusion during finasteride therapy: pathological findings from a thrombus retrieved by mechanical thrombectomy

Key Points

• To examine the pathological findings of a thrombus in a case of ischaemic stroke associated with finasteride and minoxidil use.
• Case report of a 40-year-old male with internal carotid artery occlusion during finasteride and minoxidil therapy.
• Thrombus retrieval conducted by mechanical thrombectomy for pathological evaluation.
• Analysis of thrombus composition including erythrocytes and fibrin.
• The thrombus consisted predominantly of dark red erythrocytes and fibrin.
• Finasteride may enhance coagulation through estrogen predominance due to androgen suppression.
• Both medications have been linked to cerebrovascular incidents, indicating potential risks during use.
