A 67-year-old woman with hepatitis C was found to have a liver tumor located in segment 8 during follow-up computed tomography (CT) for pyogenic spondylitis. She also had a past medical history of cirrhosis due to hepatitis C infection and diabetes mellitus. Laboratory examination showed normal levels of carcinoembryonic antigen, carbohydrate antigen 19–9, and α-fetoprotein but elevated protein induced by vitamin K antagonist-II at a level of 106 mAU/mL. Other laboratory studies showed the following: total bilirubin 0.6 mg/dL, albumin 3.2 g/dL, prothrombin time 13.7 s, aspartate aminotransferase 28 IU/L, alanine aminotransferase 22 IU/L, blood urea nitrogen 16 mg/dL, and creatinine 0.54 mg/dL. The Child-Pugh score was grade A (6 points), and the indocyanine green retention rate at 15 min was 16.6%. A diagnosis of hepatocellular carcinoma (HCC) located in segment 8 was indicated by CT (Fig. ), magnetic resonance imaging (Fig. ), and ultrasonography. The tumor was attached to the MHV. CT scans also showed multiple varices (Fig. ). MHV resection was necessary to obtain sufficient surgical margins. Central bisectionectomy (S4, S5, and S8 resection) was suggested but could not be tolerated because of her poor liver function and low future liver remnant volume, which preoperatively was only 56% by CT volumetry. Therefore, we decided to perform partial hepatectomy with MHV resection. Preoperative CT scans revealed the existence of duplicated IVC (Fig. ), so we chose to use the left IVC as the graft for reconstructing the MHV.\nThe surgery started with an inverted L-shaped incision. Intraoperative ultrasonography confirmed a 3.5-cm tumor that was touching the MHV. After mobilization of the right lobe, the liver parenchyma was transected, preserving the right hepatic vein and right anterior glissonian pedicle. A 3-cm portion of the MHV was resected around the tumor to obtain sufficient surgical margins. Immediately before resecting the MHV, we harvested the left IVC for use as the graft. After incising the retroperitoneum beside the Treitz ligament, the LRV, which had ramified from the IVC, was detected. The left IVC, which had ramified 3 cm peripherally from the origin of the LRV, was then isolated and harvested for 5 cm from the confluence of the LRV. The cut ends of the left IVC were closed with 4–0 polypropylene running sutures. The venous graft was anastomosed first to the proximal end of the MHV and then to the distal end using 6–0 polypropylene (Fig. ). A good Doppler flow through the graft was confirmed after the reconstruction. The operation required 394 min, and the estimated blood loss was 1,894 mL.\nMacroscopic evaluation showed a 35-mm bile-stained tumor (Fig. ). Histologic examination revealed moderately differentiated HCC without direct invasion of the MHV and a tumor-free surgical margin (Fig. ). The tumor was classified as stage II (T2N0M0) according to the TNM staging system for HCC. The patient recovered uneventfully and was discharged on postoperative day 12.\nThe patency of the reconstructed MHV was confirmed postoperatively by ultrasonography and dynamic CT (Fig. ). Laboratory examination 2 years after surgery showed normal levels of total bilirubin (0.6 mg/dL), albumin (4.0 g/dL), aspartate aminotransferase (24 IU/L), alanine aminotransferase (24 IU/L), prothrombin time of 13.5 s, blood urea nitrogen (15 mg/dL), and creatinine (0.46 mg/dL).\nNew lesions were found in the left lobe of the liver 4 months after surgery and in the right lobe 26 months after surgery. Both lesions were treated using transabdominal catheter embolization.
We present a case of a 54 years old male who initially presented with one month history of worsening epigastric pain and vomiting. He was referred to our care after an ultrasound and CT abdomen showing dilated common bile duct up to 13mm with no obvious intraductal obstruction. An incidental type 1 duplicated IVC was demonstrated on the CT abdomen (Figure and 2).\nNo intra-abdominal mass or lymphadenopathy were detected. Notably, he is a known BRCA2 mutation carrier. Both, his mother and sister had BRCA2-positive breast cancer. One of his great uncles also had male breast cancer. The patient was clinically jaundiced on presentation, with a bilirubin of 106. His other liver function tests were ALT at 465, GGT at 1032 and at ALP 271. His tumour markers CA-125 and CA-199 were 12 and 94 respectively.\nThe patient was subsequently found to be hypotensive and tachycardic with a new drop in haemoglobin from 100 to 72 during his stay. An urgent gastroscopy then revealed a 10mm punched-out ulcer with adherent clot at the ampulla. The lesion was partially obstructed and no active bleeding was seen. Histology on biopsy showed moderately differentiated adenocarcinoma. CT angiography was then performed. No active extravasation was seen and the gastroduodenal artery was empirically embolised with microcoils. An apparent cavitation at the medial aspect of the second part of duodenum was now identified on the CT imaging (Figure ). No metastasis was seen on staging CT imaging.\nA whipple procedure was performed. The duplicated right IVC was visualised intraoperatively with mobilisation of the uncinate process but appeared relatively normal. The left sided IVC was not encountered. No major complications were reported during his inpatient stay. Patient was discharged home and subsequently commenced on adjuvant therapy.
