ABSTRACT

Resumen La aorta shaggy se define como una degeneración ateromatosa agresiva y extensa de la aorta, cuya friabilidad predispone a ulceración y complicaciones embólicas, cursa con alto riesgo de embolia sistémica y no se conocen prevalencia ni incidencia en poblaciones de riesgo. La mayoría de casos publicados hacen referencia a complicaciones en procedimientos quirúrgicos. En la literatura no se hallaron reportes que asocien ateroembolia aórtica con obstrucción de la arteria de Adamkiewicz, cuyo diagnóstico no siempre es posible visualizando su oclusión por angiotomografía o por angiorresonancia, pues el defecto puede ser evanescente o puede existir compromiso distal con obstrucción microvascular, difícilmente aparente con arteriografía selectiva. Se presenta un caso de mielopatía isquémica embólica asociada a aorta shaggy con probable oclusión de la arteria de Adamkiewicz como responsable del deterioro neurológico agudo de la paciente, confirmado por resonancia magnética nuclear. Para caracterizar mejor esta enfermedad y para tener las estrategias diagnósticas y terapéuticas apropiadas en su abordaje oportuno, consideramos importante el reporte de casos similares aumentando así su sospecha diagnóstica.


Abstract A shaggy aorta is defined as an aggressive and extensive atheromatous degeneration of the aorta. Its friability predisposes to ulceration and embolic complications. It carries a high risk of systemic embolisms, and its prevalence and incidence in risk populations is unknown. The majority of published cases mention complications in surgical procedures. No reports have been found in the literature that associate aortic atheroembolism with obstruction of the artery of Adamkiewicz. Its diagnosis is not always possible by visualising its occlusion by computed tomography angiography or by magnetic resonance angiography, since the defects may be evanescent, or there may be a distal compromise with a microvascular obstruction, hardly apparent with selected angiography. A case is presented of embolic ischaemic myelitis associated with a shaggy aorta, with probable occlusion of the artery of Adamkiewicz being responsible form the acute neurological deterioration of the patient, confirmed by a nuclear magnetic resonance scan. In order to better describe the features of this disease and to have the appropriate diagnostic and therapeutic strategies for its timely approach, it is considered important to report all similar cases, thus increasing its diagnostic suspicion.
