The Value Of MSCT In Diagnosis Of Gastrointestinal Vascular Malformation

Objective:Gastrointestinal vascular malformation is one of the most common causes of gastrointestinal bleeding, and is a key problem for clinical diagnosis and treatment. The aim of this retrospective study was to explore the characteristics of gastrointestinal vascular malformation on contrast-enhanced MSCT (multi-slice spiral computed tomography) and the value of MSCT in diagnosis of gastrointestinal vascular malformation.Materials and Methods:The clinical and MSCT data of44patients with gastrointestinal vascular malformation between May,2008and August,2013were retrospectively collected and analyzed. All patients also received other examinations, such as endoscopy, DSA and surgery. GIVM can be demonstrated by at least one kind of examinations or surgical exploration. Clinical pathology and postoperative outcomes made the final diagnosis of gastrointestinal vascular malformation. We summarize the characteristics of contrast-enhanced MSCT in gastrointestinal vascular malformation and evaluate the value of MSCT in the diagnosis of gastrointestinal vascular malformation combined with image reconstructions such as MPR, MIP and VRT.Results:Among44cases who received contrast-enhanced MSCT examination,18cases were negative (40.9%),26cases had positive signs(59.1%). Lesions located at stomach in2cases, duodenum in1case, jejunum in10cases, ileum in3cases, ileocecal junction in1case, colon in2cases, sigmoid colon-rectum in5cases, long and diffuse lesions in1case, multiple lesions in1case. In the24local-type cases,2cases were showed contrast medium extravasation,6cases were not only showed local mural hyper-intensification, but also multiple dilated small vessels around intestinal tract,10cases were showed only local mural hyper-intensification,6cases were showed only multiple dilated small vessels around intestinal tract. Conclusion:Contrast-enhanced MSCT can show the location, extent, patterns features of gastrointestinal vascular malformation. It’s helpful for detection and localization of the gastrointestinal vascular malformation with gastrointestinal bleeding.
