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.
The search for communicating veins (CVs) between adjacent hepatic veins (HVs) has drawn its rationale from the need of reducing the risk of incomplete blood outflow in the medial portion of the hemiliver without the middle hepatic vein (MHV) in living donor liver transplantation (LDLT). However, only 24% of patients seems having CVs based on the findings of color-Doppler intraoperative ultrasound (CD-IOUS) exploration. On the other hand the safety of parenchymal sparing procedure despite HV resection let suppose that CVs are probably more frequent than expected.
Certainly, better in vivo knowledge of the rate of CVs and their direct detection would consolidate and probably further expand parenchymal sparing techniques. Taking profit from new advancements in ultrasound technology we have carried out the present study with the aim of better estimating the rate of CVs in a consecutive series of patients in whom resection of one HV at caval confluence was needed.

Anatomical resection is the gold standard approach for liver resection in patients with HCC. A new method for that by means of IOUS-guided finger compression has been devised.
Background: until now, there is no agreement about the safest and feasible method for liver parenchyma transection during laparoscopic liver resection. Study design: prospective, randomiz...
Image-guided surgery is a new technology, which is used to create 3-D pictures that generate a map of the liver. This map will allow surgeons to know the exact anatomical location of their...
Major hepatectomies have not negligible morbidity and mortality. However, when tumors invade middle hepatic vein (MHV) at caval confluence major surgery is usually recommended. Ultrasound-...
LLR was applied for tumors located at the lower edge and lateral segments of the liver that could be resected more easily than posterosuperior segments. With the development of technology ...
Inferior vena cava (IVC) resection and reconstruction with concomitant liver resection sometimes represent the only chance for patients with liver tumors involving the IVC to get cured. However, surgi...
Among all laparoscopic liver resection techniques, anatomic liver resection is one of the most challenging procedures, with disorientation readily occurring during the laparoscopic approach compared w...
The incidence of primary liver tumors is rising. Modern minimally invasive, image-guided procedures offer a potentially curative therapy option.
Liver resection in patients with neuroendocrine liver metastasis (NELM) provides a survival benefit, yet the optimal extent of resection remains unknown. We sought to examine outcomes of patients unde...
Either liver transplantation or surgical resection is available for selected patients with hilar cholangiocarcinoma. However, the comparative effectiveness between liver transplantation and liver rese...

Hepatology is the study of liver, gallbladder, biliary tree, and pancreas, and diseases associated with them. This includes viral hepatitis, alcohol damage, cirrhosis and cancer. As modern lifestyles change, with alcoholism and cancer becoming more promi...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
