- To describe mesenteric venous thrombosis (MVT) as a pathological entity,
as well as the complications associated with it.
- To recognize on computerized tomography (CT) the radiological signs compatible with a MVT.
- To identify by CT the complications derived from MVT,
especially mesenteric ischemia which has a very bad prognosis.
MVT is an uncommon disease,
it represents between 5% and 20% of episodes of mesenteric ischemia,
depending on the literature consulted.
It's potentially lethal,
between 12.5-50% of complicated cases with intestinal infarction die.
MVT presents with nonspecific symptoms and the diagnostic delay worsens the prognosis.
CT is a sensitive,
non-invasive and available imaging technique.
Classification of MVTaccording to the cause:
- Primary: idiopathic,
without risk factors.
- Secondary (most frequent) to:
closed abdominal trauma.
Inflammatory/infectious diseases: pancreatitis,
Findings and procedure details
Below we present the diagnosed cases of MVT in our center in the last five years and describe the findings detected bycontrast-enhanced MDCT of the abdomen:
- TVM is a rare entity that we should suspect with a correct clinical orientation.
- CT can detect the direct and indirect signs of TVM and its possible complications to decide the therapeutic management.
