Ectopic Embolization, Endoscopic Ultrasound (EUS)-Guided Coil Deployment, Fundal Gastric Varices, Gastric Variceal Pressure, Titanium Clips
Conditions
Brief summary
Endoscopic ultrasound (EUS)-guided coil deployment is a promising technique for the endoscopic management of gastric varices. However, coil migration may occur in patients with large drainage collaterals. This study aimed to evaluate the safety and efficacy of using clips in combination with coils for treating gastric varices. In this retrospective study, clips were placed before EUS-guided coil deployment in each patient with gastric varices and a large spontaneous portosystemic shunt. The pressure of gastric varices was directly measured by puncturing the varix with a needle connected to a pressure transducer, before and after clip placement. The occurrence of ectopic embolization or coil migration was recorded.
