Abstract
Portal vein embolization (PVE) induces hypertrophy of the future liver remnant (FLR) in patients undergoing extensive hepatic resection. Portal vein access for PVE via the ipsilateral hepatic lobe (designated for resection) places veins targeted for embolization at acute angles to the access site requiring reverse curve catheters for access. This approach also involves access close to tumors in the ipsilateral lobe and requires care to avoid traversing tumor. Alternatively, a contralateral approach (through the FLR) risks damage to the FLR due to iatrogenic trauma or non-target embolization. Two patients successfully underwent PVE via trans-splenic portal vein access, allowing easy access to the ipsilateral portal veins and eliminating risk of damage to FLR. Technique and advantages of trans-splenic portal vein access to perform PVE are described.
