RESUMEN

Introducción:

El síndrome cardiopulmonar por hantavirus (SCPH) es una enfermedad infecciosa aguda, caracterizada por insuficiencia cardio-respiratoria súbita y alta mortalidad, causada por un virus ARN del género Hantavirus, familia Bunyaviridae. Un 15 por ciento de los casos chilenos ha sido pesquisado en la Araucanía.

Objetivo:

Conocer en casos fatales de SCPH, sus características clínicas y morfológicas. Material y

Método:

Estudio descriptivo-retrospectivo de siete casos fatales con examen postmortem, de SCPH, atendidos entre 1997 y 2009 en el Hospital Regional de Temuco.

Resultados:

Los casos fueron principalmente pacientes jóvenes, rurales, con un cuadro de compromiso respiratorio progresivo, con leucocitosis, trombopenia e infiltrado pulmonar intersticial bilateral. Los principales hallazgos histopatológicos fueron un acentuado edema pulmonar intra-alveolar e intersticial, con escaso daño epitelial e infiltrado mono-nuclear y leve edema miocárdico con infiltrado mononu-clear.

Conclusiones:

Los antecedentes epidemiológicos, clínicos y laboratorio permiten sospechar SCPH. En los casos fatales la autopsia permite diferenciar el SCPH de otras patologías similares y aporta tejidos para confirmar el diagnóstico.
ABSTRACT

Introduction:

Hantavirus cardiopulmonary syndrome (HCPS) is an acute infectious disease characterized by sudden cardiorespiratory failure and high mortality, caused by a RNA virus of the genus Hantavirus, family Bunyaviridae, 15 percent of Chilean cases have been detected in the Araucania Region.

Objective:

To determine in fatal cases of HCPS, clinical and morphological characteristics. Materials and

Methods:

Descriptive-retrospective analysis of seven fatal cases with postmortem study of HCPS, attended between 1997 and 2009 at the Hospital of Temuco, Chile.

Results:

Cases were young patients from rural areas, and presented as an illness of progressive respiratory failure, with leukocytosis, thrombocytopenia and bilateral interstitial pulmonary infiltrates. Main morphological findings were marked intersticial and intraalveolar pulmonary edema, with minimal epithelial injury and mononuclear cell intersticial infiltrate and mild edematous intersticial inflamatory process.

Conclusions:

Epidemiological, clinical and laboratory background allow to suspect HCPS. In fatal cases, the autopsy makes possible to discard other similar pathologies and provide tissue for confirmation of the disease.
