ABSTRACT
La gangrena gaseosa, o mionecrosis clostridial, es una de las enfermedades infecciosas más graves, y se caracteriza por la rápida y progresiva destrucción de los tejidos blandos profundos y la producción de gas dentro de los tejidos. Presentamos un caso de gangrena gaseosa espontánea mortal causada por Clostridium perfringens en un paciente con leucemia linfocítica aguda durante la fase de quimioterapia de inducción de la remisión.
Gas gangrene, clostridial myonecrosis, is one of the most serious infectious diseases, characterized by rapidly progressive destruction of deep soft tissues and production of gas within the tissues. We presented a case of fatal spontaneous gas gangrene due to Clostridium perfringens in a patient with acute lymphoblastic leukemia during remission induction chemotherapy phase.

As infecções de tecidos moles causadas por espécies de Clostridium têm sido descritos na literatura por centenas de anos. A gangrena gasosa por Clostridium continua sendo uma importante causa de morbidade e mortalidade no mundo. O objetivo deste estudo foi relatar um caso de paciente com diagnóstico de síndrome mielodisplásica, submetida à curetagem uterina e evoluindo com gangrena gasosa espontânea, 10 horas após a cirurgia.Paciente do sexo feminino, 26 anos, com história de dor em terço distal de membros inferiores, irradiando para região de fossa poplítea, com piora à palpação e movimentação dos membros, acompanhada de aumento da temperatura e volume local. Negava febre, hiperemia ou trauma local, evoluindo para choque séptico. Angiotomografia das extremidades e pelve revelou a presença de gás permeando os feixes musculares da coxa e da perna, bilateralmente. A combinação da história e exame clínico,ao estudo radiológico confirmou o diagnóstico sindrômico de gangrena gasosa espontânea. Apesar de elevado índice de suspeição melhorar os resultados clínicos, tais infecções progridem tão rapidamente que o óbito pode preceder o diagnóstico,não obstante, o reconhecimento precoce e tratamento agressivo,incluindo drenagem aberta ou percutânea. Antibióticos parenterais contra Clostrídios devem ser prontamente iniciados, bem como medidas de suporte clínico.
The soft tissue infections caused by Clostridium species have been described in the literature for hundreds of years. The gas gangrene due to Clostridium remains an important cause of morbidity and mortality worldwide. The aim of this study was to report a patient diagnosed with myelodysplastic syndrome who underwent curettage, evolving with spontaneous gas gangrene, 10 hours after surgery. Female patient, 26 years, with pain in the distal third of the lower limbs, radiating to the popliteal fossa region, which worsened on palpation and movement of limbs, and accompanied by an increase in temperature and local volume. She denied fever, redness or local trauma, and progressed to septic shock. Angiotomography of the extremities and pelvis revealed the presence of gas permeating the muscle bundles of the thigh and leg bilaterally. The combination of history and clinical examination and radiological examination confirmed the syndromic diagnosis of Spontaneous Gas Gangrene. Although a high index of suspicion may improve clinical outcomes, such infections progress so rapidly that death usually precedes the diagnosis. However, early recognition and aggressive treatment, including open or percutaneous drainage and parenteral antibiotics against Clostridia should be promptly initiated, along with clinical support.

Massive intravascular hemolysis is a rare yet often fatal complication of clostridial sepsis. The only chance for survival is an early diagnosis and prompt initiation of treatment. We report a rapidly fatal case who developed electrocardiographic changes of acute myocardial injury. Autopsy showed gas-filled bubbles and cysts in the myocardium partially filled with sporulating bacilli with the morphology of clostridia. Gas filled bubbles were also present in the lungs, liver, kidneys and spleen. The gastric mucosa showed hemorrhagic and necrotizing changes, the probable site of entry of the infection
