title: [Pitfall of postoperative right gastroepiploic artery angiogram].
abstract: Postoperative angiogram of the right gastroepiploic artery (RGEA) often revealed a complication as a 'string sign' or 'competition phenomenon'. Inadequate evaluation of the string sign or competition phenomenon was encountered in this study. In a 62-year-old male, an angiogram using a low-dose contrast medium showed a string sign of the RGEA, but a high-dose contrast medium demonstrated an adequate diameter of the RGEA with good flow. In a 68-year-old male, celiac artery angiograms showed the occlusion of the RGEA, although super selective angiograms indicated the RGEA to be patent. Adequate evaluation of the RGEA should include a super-selectiveangiograms.
