ABDOME AGUDO PERFURATIVO PDF

To report a surgical case with a diagnosis of COVID that developed acute perforated abdomen and pneumothorax.. This was an year-old female patient with respiratory symptoms, with dry cough and fever and diffuse abdominal pain with signs of peritonitis. Computed tomography of the chest and abdomen showed pneumothorax on the right and extensive pneumoperitoneum.. The presentation of COVID with severe pulmonary and abdominal complications requires specialized and emergency treatments, but it has high mortality rates.. The Coronavirus belongs to a family of RNA viruses that can cause respiratory infection with varied symptoms, with COVID being a new type of microorganism belonging to this family described in the last months of , of which symptoms usually include coughing, fever, fatigue, headache and myalgia after 2—14 days of exposure.

When and why use unenhanced computed tomography in patients with acute abdomen. The use of unenhanced computed tomography has been frequently recommended for the initial assessment of patients with clinical suspicion of acute abdomen instead of other diagnostic methods. The authors present a review of the literature on the main aspects, advantages, limitations and efficacy of unenhanced computed tomography for the diagnosis of acute appendicitis, renal colic, diverticulitis, acute pancreatitis, primary epiploic appendicitis, pneumoperitoneum and small bowel obstruction.

The advantages and limitations of this technique are also discussed.
