Sumario:Gastric varices are found in approximately 20% of patients with portal hypertension. Endoscopic procedures involving the injection of cyanoacrylate (CYA) have proven to be the therapies of choice for primary treatment of gastric varices and have resulted in higher hemostasis rates and lower recurrent bleeding rates compared with band ligation and sclerotherapy. Nevertheless, serious adverse events associated with CYA injection, including glue embolization, have been reported in numerous articles and have occasionally led to fatal adverse events. Gastric fundal varices with abnormal shunts are higher-risk than those without abnormal shunts, and their treatment is more challenging. Endoscopic ultrasound (EUS)-guided puncture is an important technique in the field of digestive endoscopy. EUS has advantages that include improved therapeutic targeting, enhanced variceal detection, the ability to confirm varix obliteration with Doppler examination, and the ability to perform accurate observations of gastric varices that are not affected by blood in the stomach. The coils currently used for intravascular embolization can be precisely delivered into a varix through fine-needle puncture under EUS guidance, and this technique has provided a new approach for varix obliteration. We herein describe two patients with severe gastric fundal varices who were treated with EUS-guided coil injection and CYA embolization.
