Necrosis digital en la mano por mecanismo infrecuente


A 43-year-old, non-smoking man presented with acute ischemic lesions of his left hand. He had been taking beta-blockers for his arterial hypertension. The day before the occurrence of these acute lesions, he self medicated with a drug containing ergotamine and caffeine because of a headache. About one hour after mild trauma to the hand, he noticed intense cyanosis accompanied by severe pain in the fingers that progressed to digital necrosis. Hematological tests, hand radiography, echo Doppler, and nailfold videocapillaroscopy were performed. Digital necrosis owing to an unusual combination of ischemic mechanisms is assumed.
