Living-related liver transplantation: is Doppler sonography sufficient to define the hepatic artery anatomy before surgery?

OBJECTIVE

to evaluate the accuracy of colour Doppler sonography (CDS) in the assessment of the left hepatic arterial supply in living donors before hepatic transplantation.

MATERIAL AND METHODS

Pre-operative sonographic Doppler data of the left hepatic artery (LHA) were compared retrospectively with the selective hepatic angiographic data and the intra-operative observations in 60 living donors.

RESULTS

Pre-operative Doppler data of the LHA were available in 53 cases and incomplete or absent in seven cases. In 51 cases (96%) the origin of the LHA or an accessory LHA were correctly described at Doppler sonography (44 classical LHA in anatomic position, seven accessory LHA). In 11 cases (21%), Doppler data were insufficient or incorrect to define the arterial supply of the hepatic segments II, III and IV. Doppler studies were unable to determine the length or the diameter of the LHA.

CONCLUSION

Doppler sonography seems to be able to define the main left hepatic artery anatomy. Selective hepatic angiography is still indicated to determine the length, diameter and intra-hepatic segmental supply.
