Abstract:
Objective To explore the characteristics of gastrointestinal vascular malformation on contrast-enhanced multi-slice spiral computed tomography(MSCT)and assess the value of MSCT in diagnosis of gastrointestinal vascular malformation.Methods Forty-four patients with the final diagnosis of gastrointestinal vascular malformation were collected and analyzed retrospectively.We summarized the characteristics of contrast-enhanced MSCT in gastrointestinal vascular malformation and evaluated the value of MSCT in the diagnosis of gastrointestinal vascular malformation combined with image reconstructions such as MPR,MIP and VRT. Results Among 44 cases who received contrast-enhanced MSCT examination,18 cases were negative(40.9%),26 cases had positive signs(59.1%).In the 26 cases,1 case with diffuse lesions,1 case with multiple lesions,the others were local-type cases,in which 2 cases were showed contrast medium extravasations,6 cases were not only showed local mural hyper-intensification,but also multi-ple dilated small vessels around intestinal tract,10 cases were showed only local mural hyper-intensification,6 cases were showed only multiple dilated small vessels around intestinal tract.In the 24 local-type cases,lesions located at the stomach in 2 cases,the du-odenum 1 case,the jejunum 10 cases,the ileum 3 cases,the ileocecal junction 1 case,the colon 2 cases,the sigmoid colon-rectum 5 cases,respectively.Conclusion Contrast-enhanced MSCT can show the location,extent,patterns features of gastrointestinal vascu-lar malformation.It is helpful for detection and localization of the gastrointestinal vascular malformation with gastrointestinal bleed-ing.
