Correlation of gastrointestinal perforation location and amount of free air and ascites on CT imaging.

Purpose: To analyze the amount of free abdominal gas and ascites on computed tomography (CT) images relative to the location of a perforation.

Methods: We retrospectively included 172 consecutive patients (93:79 = m:f) with GIT perforation, who underwent abdominal surgery (ground truth for perforation location). The volume of free air and ascites were quantified on CT images by 4 radiologists and a semiautomated software.

A rare case of jejunal arterio-venous fistula: treatment with superselective catheter embolization with a tracker-18 catheter and microcoils.

Arterio-venous fistulas may develop spontaneously, following trauma or infection, or be iatrogenic in nature. We present a rare case of a jejunal arterio- venous fistula in a 35-year-old man with a history of pancreatic head resection that had been performed two years previously because of chronic pancreatitis. The patient was admitted with acute upper abdominal pain, vomiting and an abdominal machinery-type bruit.
