SUMMARY: Several vital structures, of both the aerodigestive and vascular systems, are contained in the cervical regions. Cervical lesions have high complexity and high morbidity and mortality. They are more common in young men inserted in a context of violence. The objective of this study was to demonstrate an injury by firearm with transfixation of the trachea, approached by cervicotomy in which was performed a termino-terminal anastomosis of the affected segment. The patient presented satisfactory clinical and surgical outcomes.  

The Fournier’s Syndrome is characterized by a necrotizing infection that can affect regions such as perineum, thighs, scrotum, thigh roots and lower abdomen. It begins insidiously, but progresses with great tissue loss and is of difficult handling. It is an uncommon morbidity of the population at large. Recurrence is poorly documented, which makes its occurrence atypical in medical practice. The mortality rate varies from 10% to 30.8% in Brazil without changes over time despite advances in technology and in surgical techniques. The objective of this study is to demonstrate a recurrence of the syndrome in a male, 46-year-old patient, with diabetes, hypertension and grade III obesity. The patient was treated in a timely manner with satisfactory clinical and aesthetic outcomes.

Acute mesenteric ischemia is not a common affection, it happens in 1 to 1,000 people in the United States. Acute mesenteric ischemia should always be one of the differential diagnoses for abdominal pain as it is difficult to diagnose and has very high mortality rates. Among its causes, the most uncommon remains the obstruction caused by displacement of atherosclerotic plaques. Therefore, the description of a case of acute mesenteric ischemia caused by detachment of a plaque in the thoracic aorta is contributing to academic field. The present case was treated by immediate exploratory laparotomy with resection of the distended segments and implantation of an endoprosthesis via femoral artery. Keywords: Bile duct cancer.

Por ser de difícil diagnóstico e de elevada mortalidade deve sempre ser um dos diagnósticos diferenciais para dor abdominal. Dentre suas causas, mais incomum ainda é a obstrução causada por deslocamento de placa aterosclerótica. Portanto, torna-se útil demonstrar um caso de isquemia mesentérica aguda causada por descolamento de placa da aorta torácica, tratado por laparotomia exploradora imediata com ressecção das alças em sofrimento e implantação de endoprótese torácica reta via femoral.   Palavras-chave: Câncer de ducto biliar.
