Fig. 1From: Two cases of catheters inserted from the femoral vein straying into the hepatic vein, possibly owing to a Eustachian valve: a case reportEchocardiographic and CT images in case 1 showing a strayed guidewire that was inserted from the FV to the HV. A TEE image of the IVC and HV junction. The GW was obstructed by the EV and strayed into the HV. B Coronal CT image of the junction of the HV and the IVC. The angle between the IVC and the HV is 129°, which is an obtuse angle. A low-absorption density indicating the Eustachian valve is seen on the right atrial side of the junction between the HV and the IVC. CT, computed tomography; FV, femoral vein; TEE, transesophageal echocardiography; ▼GW, guidewire; IVC, inferior vena cava; EV*, Eustachian valve; RA, right atrium; HV, hepatic veinBack to article page
