Introduction. Over the past few years, liver surgery has been in constant evolution and gained many improvements that helped surgeons push limits further. A complex procedure such as left extended trisectionectomy, as described by Makuuchi in 1987, may be performed in selected cases. Aim. Describe a case of successful resection of a huge bilobar liver sarcoma involving all hepatic veins from a young female patient, in which the blood outflow was preserved through an inferior right hepatic vein, leaving only segment 6 as liver remnant. Case Report. A 19-year-old female with a 3-month history of abdominal pain, vomiting, and weight loss was referred for our evaluation. CT scan and MRI revealed a heterogeneous and bulky expansive hepatic lesion, sparing only segment 6, with an estimated volume of 530 cm3, corresponding to a 1.2 FLR/BW ratio. The tumor involved the three major hepatic veins, but an inferior right hepatic vein was present, draining the spared segment 6. She was submitted to a left trisectionectomy extended to the caudate lobe and segment 7, including resection of all hepatic veins and lymphadenectomy of the hepatic pedicle. She was discharged on the 7th postoperative day without complications. The histopathological and immunohistochemical analysis demonstrated an undifferentiated embryonal sarcoma of the liver. Conclusion. Inferior right hepatic vein-preserving left extended trisectionectomy is a safe and feasible procedure that should be performed by a hepatobiliary team experienced in major complex hepatectomies.

Background. An adequate blood flow is directly related to graft survival in living donor liver transplantation. However, in some cases, unfavorable conditions prevent the use of the hepatic artery for arterial reconstruction. Herein, we report a case in which the recipient right gastroepiploic artery was used as an option for arterial reconstruction in adult-to-adult living donor liver transplantation. Case Report. A 62-year-old woman, with cirrhosis due to hepatitis B associated with hepatocellular carcinoma, was submitted to living donor liver transplantation. During surgery, thrombosis of the hepatic artery with intimal dissection until the celiac trunk was observed, which precluded its use in arterial reconstruction. We decided to use the right gastroepiploic artery for arterial revascularization of the liver graft. Despite the discrepancy in size between donor hepatic artery and recipient right gastroepiploic artery, anastomosis was performed successfully. Conclusions. The use of the right gastroepiploic artery as an alternative for arterial revascularization of the liver graft in living donor liver transplantation should always be considered when the hepatic artery of the recipient cannot be used. For performing this type of procedure, familiarity with microsurgical techniques by the surgical team is necessary.

Inflammatory pseudotumor of the liver (IPTL) is a rare condition, but an important differential diagnosis of hepatic space-occupying lesions. It may regress spontaneously and mimic other liver tumors. Complications are usually intrahepatic. Herein, we present a case of IPTL which developed pleural empyema and lung necrosis as an uncommon complication.
