CO2 splenoportography: preliminary results.
OBJECTIVE
Previously, splenoportography with 18-gauge needles provided excellent portal imaging. However, because of concern about bleeding, this technique was replaced with arterial portography and noninvasive techniques, which are not always accurate. We present a modification of splenoportography using CO2 and an ultrafine needle in eight patients whose previous imaging studies were inconclusive.


CONCLUSIONS
CO2 splenoportography is safe and expedient and provides adequate visualization of the portal system for surgical planning in selected patients.
