A Transverse liver ultrasound scan demonstrating a hepatic venous malformation (HVM) (marked by a star) that is compressing the inferior vena cava (arrowhead) and hepatic veins (arrows). B A 22-gauge Chiba needle (arrowhead) is passing between hepatic veins (red arrow) into the haemangioma, with a significant portion of normal liver tissue transgressed to reduce the risk of bleeding. C Another patient with HVM during ultrasound-guided access, in which the intervening normal liver parenchyma is notable (curved arrow), and the needle tip (red arrow) is slightly away from the cystic area (arrowhead)
