Summary
Brief summary (as posted)
The search for communicating veins (CVs) between adjacent hepatic veins (HVs) has drawn its rationale from living donor liver transplantation (LDLT). Parenchymal sparing procedures although HVs are resected suggest that probably their presence is underestimated. Taking profit from new improvements in ultrasound technology the investigators aim to better estimate the rate of CVs in a consecutive series of patients in whom resection of one HV at caval confluence is needed.

Arms and outcomes
Arms (1)
- label
- caval confluence HV involvement
- description
- Patients carriers of primary or metastatic tumour with direct contact or invasion of one HV at the caval confluence.
- interventionNames
- Procedure: Ultrasound guided liver resection
Primary outcomes (1)
- measure
- First outcome was the rate of CVs detectable with e-flow IOUS along clamping of the HV for which resection could be needed.
Secondary outcomes (1)
- measure
- Secondary outcome was safety (morbidity, mortality, blood loss, blood transfusions) of the procedure.
