Methods 16 cases of jejunoileal vascular malformation were diagnosed by mesenteric selective angiography. Subsequent superselective catheterization of a bleeding branch was performed. The guide wire was placed as a marker for intraoperative location. Results 9 cases of intestinal vascular malformation were located in the jejunum, 6 in the ileum, 1 in the jejunum and colon. At operation, the guide wire could easily be found and subsequent surgical resection performed successfully. Conclusion Placing the guide wire as a marker by angiographic techniques is quite useful in locating intraoperatively the exact bleeding site of jejunoileal vascular malformation.
