Ascending colonic variceal bleeding: utility of phase-contrast MR portography in diagnosis and follow-up after treatment with TIPS and variceal embolization.
The authors describe the discovery of ascending colonic variceal veins via celiomesenteric diagnostic angiography following a bout of melena in a 44-year-old woman. Magnetic resonance imaging, including phase-contrast MR venography, allowed visualization of the portal and systemic veins immediately after the initial angiograms. The hemorrhagic episode did not resolve until after transjugular intrahepatic shunt insertion and selective variceal embolization through the shunt. At 1 week-, 3 months-, and 6 months post treatment, follow-up MR venography no longer revealed the presence of colonic varices. Colonoscopy at 6 months was normal and the patient did not have any further episodes of bleeding until a liver transplantation was performed after 9 months.
