EUS-Guided Vascular Interventions

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Vascular Medicine

Background:

• Endoscopic ultrasound (EUS) is a powerful tool for visualizing and accessing intra-abdominal vasculature.
• Traditional methods had limitations in accessing these areas.

Purpose of the Study:

• To review current and future applications of EUS in vascular diagnostics and interventions.
• To detail EUS-guided techniques for specific vascular conditions.

Main Methods:

• Comprehensive literature review of key studies on EUS-based vascular applications.
• Focus on diagnostic techniques (portal pressure, tumor cell sampling) and interventional procedures (varices, pseudoaneurysms).

Main Results:

• EUS enables accurate portal pressure measurements for liver disease prognostication.
• EUS-guided interventions effectively treat gastric varices and visceral artery pseudoaneurysms.
• EUS facilitates portal venous sampling for cancer diagnosis.

Conclusions:

• EUS is a versatile modality for advanced vascular diagnostics and interventions.
• Emerging EUS applications include liver tumor ablation and TIPS placement.
