Summary

This study tested a new way to treat enlarged veins in the stomach that can bleed. Doctors placed small clips before inserting coils to keep the coils from moving to the wrong place. The study included 31 patients with large abnormal blood vessels. Results showed the clip-and-coil method was safe and helped prevent coil migration.
