Abstract

Medullary ischemia secondary to surgical procedures of the infrarenal aorta is an infrequent and mostly devastating complication of this procedure, and its nonspecific clinical presentation makes it difficult to promptly diagnose. Prevention measures for this complication are not yet clear; therefore, the need for anticoagulant and/or antiplatelet therapy is discussed. This paper reports a case of a 69-year-old Hispanic man presenting with sudden pain and signs of ischemia on his left lower extremity 8 weeks after endovascular repair with endoprosthesis of an infrarenal aorta and left iliac aneurysm. The patient was admitted to the emergency room, where an extensive arterial thrombosis compromising the right iliac and femoral arteries was diagnosed. Dual anticoagulation and antiplatelet therapies were initiated, and therapeutic ranges were achieved. Nonetheless, the patient presented medullary ischemia by microembolization diagnosed by contrast-enhanced magnetic resonance imaging, with unsatisfactory evolution of an intracranial hemorrhagic event without documented excessive anticoagulation. The patient developed permanent pure motor deficit of his lower extremities, absence of sphincter control, and mild cognitive impairment. ...Continue Reading
