- 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 MVT according to the cause : - Primary : idiopathic,
without risk factors. -...
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.
