Colopericardial fistula presenting with massive rectal bleeding.

Colopericardial fistulae constitute a condition with a very low prevalence and a high morbidity and mortality rate. In this case report, we discuss an 80-year-old male patient who presented to emergency services for massive rectal bleeding and signs of hypovolemic shock. Abdominal arteriography and upper gastrointestinal endoscopy were negative for bleeding.

Diagnostic performance of CT angiography in neck vessel trauma: systematic review and meta-analysis.

This study was conducted in order to define the diagnostic performance of CT angiography for vascular injuries compared with angiography in patients with neck trauma. CT angiography is the cornerstone of diagnosis for hemodynamically stable patients with wounds suspicious of vascular trauma in the limbs, chest, or abdomen. Available evidence for the use of CT angiography in neck vascular trauma comes from small case series and few randomized controlled trials, and high-quality information does not exist regarding its performance.

Diagnostic performance of CT esophagography in patients with suspected esophageal rupture.

Esophageal rupture is a surgical catastrophe. The gold standard for diagnosing is iodine, water-soluble contrast medium esophagography. CT esophagography has shown promising results.

[Efficacy of multidetector computed angiotomography in the diagnosis of limb arterial injuries].

Objective: To determine the diagnostic usefulness of multidetector computed angiotomography in the diagnosis limb arterial injuries in patients with suspicion of arterial injury with no indication of immediate surgery.

Methods: Non-invasive 64-channel multidetector computed tomography (MDCT) was performed on 99 limbs suspected of having a traumatic vascular injury over a 44-month period between August 2004 and April 2008. The results were interpreted by the duty radiologist and his findings were compared with those from surgery or clinical follow-up.
