Endoscopic Ultrasound Bubble Study for Detection of Extracardiac Shunting: Endohepatology in the Diagnosis of Hepatopulmonary Syndrome

Abstract

Contrast echo is often used to demonstrate extracardiac shunting for evaluation of hepatopulmonary syndrome. The same can also be performed via transesophageal route with endoscopic ultrasound. We here demonstrate this technique in a 58-year-old woman who underwent gastric variceal obliteration with endoscopic ultrasound. This technique can add another dimension to the "one-stop-shop" endohepatology evaluation of patients with cirrhosis in a single endoscopy appointment.
