A 30-year-old HBsAg-positive woman was admitted to the hospital because of 6 days of progressive shortness of breath. She was in severe respiratory distress with circulatory collapse. She had an enlarged liver but no stigmata of chronic liver disease or signs of cirrhosis. She had rapidly developed respiratory arrest and was transferred to intensive care unit. Heart ultrasonography and Doppler scan showed right heart straining and high pulmonary artery pressure. Despite cardiovascular and respiratory support she died a few hours after admission. Autopsy revealed combined hepatocellular-cholangiocarcinoma infiltrating the entire liver, metastatic invasion of lung blood vessels and absence of right ventricular hypertrophy. The incidence of hepatocellular-cholangiocarcinoma, a variant of hepatocellular carcinoma, is roughly 2-3% and the presenting symptoms are abdominal pain, weight loss, jaundice, fever or decompensation of liver disease. Associated HBsAg positivity and cirrhosis are reported in 20-30% and 60% of patients, respectively. Metastases to lungs are relatively frequent but this is the first report of hepatocellular-cholangiocarcinoma presented with acute respiratory distress due to massive pulmonary embolism.

The development of hepatic surgery involved also definition of indications for resection in primary liver tumours. Based on an analysis of a group of 76 patients with primary liver tumours operated in 1978-2001 (up to the end of October) the authors evaluated the indication criteria for resection of primary hepatic tumours. As to benign tumours most frequently haemangiomas were resected (in 35 patients) and follicular nodular hyperplasia in 10 patients. Indication for resection was the symptomatology of the tumour (40x), signs of progression during a check-up examination (13x) or doubts as regards preoperative ruling out of malignity (16x). Hepatocellular adenoma was resected in 8 patients, incl. 7 where the preoperative diagnosis was assessed by bioptic examination. The extent of resection depended on the size and site of the tumour, in haemangiomas and follicular nodular hyperplasia non-anatomical resections predominated (in 27 patients). On account of hepatocellular carcinoma resections were made in 18 patients, incl. 8 who suffered also from cirrhosis which limited the extent of resection. In patients without cirrhosis with carcinoma in one of the lobes an anatomical resection was implemented. Postoperative complications developed in 14 patients (18%), two died (3%) from hepatic failure and pulmonary embolism.

Hepatocellular carcinoma (HCC) is the most common malignant tumor of the liver. Although several therapeutic options have been advocated, transcatheter arterial chemoembolization (TACE) in particular has been widely performed in the treatment of HCC. Still, hepatic arteriography and portography are mandatory for evaluation of (a) the resectability and multiplicity of HCCs and (b) the hemodynamic status of the portal vein. Thereafter, TACE can be considered as the initial therapeutic modality. The possibility of nontarget organ complications during TACE (eg, ischemic cholecystitis, splenic infarction, gastrointestinal mucosal lesions, pulmonary embolism and infarction, spinal cord injury, ischemic skin lesions) should be taken seriously. A thorough understanding of the anatomic variants and hemodynamic features of the hepatic artery and portal vein is the first step in performing effective and safe TACE for HCC.

A 68-year-old man with reactive thrombocytemia (platelet count: 97.2 x 10(4).mm-3) underwent liver subsegmentectomy for hepatocellular carcinoma. Thoracic epidural combined with general anesthesia was carried out for the surgery. Platelet aggregability was monitored during the operation. At the beginning of the operation, platelet aggregability to aggregating factor ADP showed an abnormal pattern without dose dependency. In spite of continuous administration of gabexate mesilate for inhibition of thrombosis, the patient developed hypercapnia with low end tidal CO2 pressure (PETCO2) and hypoxia, suggesting pulmonary embolism. PETCO2 and SPO2 recovered soon after heparin administration. The patient recovered without any neurologic complications. This case demonstrated that hyperaggregability is possible in patients with thrombocytemia and suggests that monitoring of platelet function in patients with thrombocytemia is difficult.

Radiofrequency is increasingly used to manage liver tumors. This report describes the case of a 74-year-old man who received two courses of percutaneous radiofrequency thermal ablation for a hepatocellular carcinoma over a 4-month period. He subsequently required computed tomography-guided drainage for an area of intrahepatic necrosis. During the procedure, hemobilia developed, followed by respiratory distress and collapse. The diagnosis of bile pulmonary embolism was established on the basis of high biliary acid concentrations in pulmonary fluid aspiration and blood plasma. Radiofrequency thermoablation provides local control of advanced liver tumors with low recurrence and morbidity. However, this interventional procedure risks damage to liver parenchyma involving vascular and biliary structures, which may lead to biliary-venous fistula and possible bile emboli.

A 71 year old patient presented with a non-ST segment elevation acute myocardial infarction. The echocardiogram showed several masses attached to the interatrial septum. Several days after admission the patient died. A postmortem examination found a large hepatocarcinoma with intravascular and intracardiac metastases and several myocardial infarctions of different ages. The infarctions had been caused by coronary paradoxical embolisms through a patent foramen ovale and contained neoplastic cells from the liver carcinoma, which had not been diagnosed. The cause of death was a massive pulmonary embolism.

Hepatocellular carcinoma (HCC) advancing to the right atrium (RA) through the hepatic vein has generally been regarded as a terminal lesion of carcinoma. However, because tumor thrombus (TT) in the RA may cause sudden death by heart failure or pulmonary embolism, it is a pathologic condition that needs emergency extraction. Our case was a 55-year-old male. The HCC had a main lesion in the anterior region of the hepatic right lobe, accompanying TT highly occupying the region from the middle hepatic vein and inferior vena cava to the RA. For this tumor, we conducted an extended right anterior segmentectomy and extraction of the TT in the RA under an extracorporeal circulation. He was discharged on the 28th day after surgery, and at present, when 12 months have passed since the surgery, survives without any sign of its recurrence. There have been eight HCC cases including our case, reported regarding the simultaneous resections of a main tumor and TT under cardiopulmonary bypass. Because two patients among this group of eight survived for more than two years, resection is recommended even for advanced HCC highly infiltrating to the RA.

Intracardiac manifestation of hepatocellular carcinoma (HCC) is a rare condition and an uncommon finding even at autopsy. Pulmonary tumor embolism as a presenting feature of HCC has been published only twice previously. In our case report, a 63-year-old man presented with high fever and six episodes of recurrent pneumonias during the last half year. Echocardiography was performed, a solid mass was found in the right atrium. Transesophageal echocardiography proved a tumor mass in the inferior vena cava (IVC) extending into the right atrium, abdominal ultrasound revealed tumor mass in the IVC and a solid tumor in the liver. Combined liver and heart surgery was attempted in order to remove the tumor mass from both the liver and the right atrium. Acute cor pulmonale occurred during tumor removal from the right atrium and the patient expired. In addition to local factors the possibility of embolization should arise in the background of recurrent pneumonia. Occult carcinoma must be included in possible causes of recurrent pulmonary embolism. Searching for primary malignancy should include HCC as frequent cause of hypercoagulability. In case of HCC, echocardiography is suggested because of the possibility of expansion in IVC or right atrium and tumor-embolization.

The case of a child with advanced hepatocellular carcinoma that did not respond to systemic chemotherapy is presented. Three courses of chemoembolization (hepatic arterial chemoembolization) were given, with partial tumor response. The hepatic artery was cannulated via the femoral artery using the Seldinger technique. Arteriography was performed, and chemoembolization suspension (cisplatin + doxorubicin + mitomycin mixed with Lipiodol) was injected. After the third hepatic arterial chemoembolization, the patient developed fatal pulmonary oil embolism. Hepatic arterial chemoembolization seems to be a useful method for treatment of high-risk hepatocellular carcinoma cases, which can induce responses, even in metastatic patients refractory to standard systemic chemotherapy. However, it may result in pulmonary embolism, which is a potentially fatal complication. In children, Lipiodol should be used as an embolizing material and cytostatic carrier with extreme care. Consideration should be given to replacing it with other materials, including albumin or collagen.

A 48-year-old patient with known alcohol abuse and long-standing liver cirrhosis presented with spontaneous bacterial peritonitis and subsequent hepato-renal syndrome. Autopsy revealed a large hepatocellular carcinoma of the right liver lobe. Histologically, pulmonary arteries, arterioles, and capillaries were occluded by numerous tumor emboli. Small tumor emboli also covered the endocardium of the right ventricle. A review of the literature shows that macroscopic as well as microscopic pulmonary tumor embolism is often diagnosed in patients with a previously unknown malignancy. Moreover, pulmonary tumor embolism radiologically mimics pneumonia, tuberculosis, or interstitial lung disease. Therefore, an autopsy should be considered in cases of fulminant or massive pulmonary embolism to exclude tumor embolism even when the patients' history is insignificant as to this point, and in cases with known malignant tumors and respiratory symptoms to exclude tumor microembolism.
