Technical tips for EUS-guided embolization of varices and pseudoaneurysms

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Vascular Medicine

Background:

• Endoscopic ultrasound (EUS)-guided vascular interventions offer advanced diagnostic and therapeutic options.
• EUS-guided embolization is a key technique for gastric varices, but lacks standardized protocols.
• Reviewing techniques and challenges is vital for improving EUS-guided embolization of varices and pseudoaneurysms.

Purpose of the Study:

• To review and demonstrate EUS-guided embolization techniques for various vascular lesions.
• To highlight challenges and optimize outcomes in EUS-guided vascular interventions.
• To consolidate existing literature on EUS-guided embolization therapy.

Main Methods:

• EUS-guided embolization performed using a combination of coils and cyanoacrylate.
• Techniques include direct varix puncture/embolization and feeder vessel embolization for gastric varices.
• Accompanying video demonstrates techniques for lesions like gastric varices, ectopic duodenal varices, and splenic artery pseudoaneurysms.

Main Results:

• Successful treatment of gastric varices, ectopic duodenal varices, and splenic artery pseudoaneurysms.
• Complete obliteration of vascular lesions confirmed by Doppler ultrasound showing absence of flow.
• Demonstrated efficacy of combined coil and cyanoacrylate embolization therapy.

Conclusions:

• EUS-guided embolization is an effective treatment for diverse vascular pathologies.
• Understanding procedural techniques and potential challenges is crucial for successful outcomes.
• Standardization and further data are needed to optimize EUS-guided embolization therapy.
