Two hundred twenty-five transcatheter hepatic arterial embolizations (TAEs) were performed on 137 patients with hepatocellular carcinoma (HCC) during a three-year period. The postembolization changes of the gallbladder were studied by regular follow-up with ultrasonography. Twenty-four patients (10.7%) were found to have an acute infarction of the gallbladder within two weeks immediately following chemoembolization. Gallbladder infarction was related to inadequate superselectivity, regurgitation of chemoembolus, or unavoidable anatomic limitations. Four of the 24 patients were found to have delayed formation of gallstones, with the time lapses after TAEs being 2, 2, 3, and 5 months, respectively. One patient underwent surgical reexploration for cholecystectomy 14 months after resection of her HCC because of intractable symptoms and signs of chronic cholecystitis. There are four possible mechanisms of development of gallstones. Cholecystectomy should be performed during the elective hepatectomy for resectable HCC in patients who have received preoperative TAEs.

The arterial infusion of lipiodol (LPD) containing SMANCS (SMANCS/LPD) has been considered to be a tumor-targeting therapy for hepatocellular carcinoma (HCC). It is important to establish a role of this new therapy in systematic strategies for HCC. LPD has no embolic effect, and the lipophilic anti-cancer agent, SMANCS, suspended in LPD and delivered selectively in tumors, shows therapeutic effect. Accordingly, it is essential for therapeutic efficacy that HCC cells have a chemosensitivity to SMANCS. The maximum dose of SMANCS/LPD is 6 ml at one time, which is not sufficient for voluminous tumors. These are the disadvantages of SMANCS/LPD therapy. Furthermore, HCC tissues, in which lipiodol is retained, is limited to moderately differentiated, with large blood spaces. SMANCS/LPD is not effective for well- and poorly -differentiated HCCs, because blood spaces in these histological types are too small for SMANCS/LPD to be deposited. On the other hand, transcatheter arterial embolization therapy (TAE) is effective by occluding feeding artery with small pieces of gelatin sponge, and a much tumor necrosis is obtained by TAE at one time. However, HCC cells beneath and within the capsule, and invading outside the capsule, are viable, possibly due to backflow of blood via drainage vein. Tumor thrombi and tiny intrahepatic metastases also escape the TAE effect. Previously we reported the new therapy at the first time: the combination of arterial infusion of SMANCS/LPD and TAE (LpTAE). LpTAE has some therapeutic benefits of both therapies; SMANCS/LPD fills up a whole tumor, and part of the LPD flows out from the tumor, is trapped in the capsular invasion and microscopic metastatic foci with the necrotic change. LPD prevents regurgitation of blood flow in drainage vein, and promotes necrotic change. After LpTAE, Lipiodol CT shows 4 kinds of LPD-deposition pattern in HCC; the therapeutic effects of LpTAE are exactly evaluated by these patterns. For total necrosis, HCC nodule shows a complete type, in which the whole tumor shows a metallic density by lipiodol deposition. In other patterns, the LPD-deposited area in tumors generally shows necrosis, and non-LPD-deposited areas are viable. The second line of the therapies. PEIT or resection, can be selected by the LPD-deposition pattern. We consider that the intraarterial infusion of SMANCS/LPD reinforces TAE, and LpTAE is one of the most effective therapies.

This paper reports the use of cardiopulmonary bypass with mild hypothermia for the successful en bloc resection of a hepatocellular carcinoma in a cirrhotic liver with a tumor thrombus extending into inferior vena cava (IVC) and to the right atrium (RA), often prolapsing the tricuspid valve. The patient was a 77-year-old woman with antibodies against hepatitis C virus (HCV) and a serum alpha-fetoprotein (AFP) concentration of 13,566ng/mL. Imaging showed a large tumor in the left lobe of the liver extending into the RA, which often was prolapsed the tricuspid valve to produce mitral valve regurgitation. To prevent intraoperative pulmonary thromboembolism, both cardiac arrest and hepatic vascular occlusion with mild hypothermia were applied. The RA and IVC tumor thrombus and left liver were resected in en bloc. The cardiac arrest and hepatic vascular exclusion times were 56 and 15 min, respectively. The operation took 11 h, and the total blood loss was 1,078mL. The resected specimen weighed 1,000g and the tumor measured 8.0 x 7.8cm.

A patient who developed necrotizing pancreatitis after transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) is presented. A 55- year-old man had been followed for chronic hepatitis B infection for 10 years at another institution. He presented with multiple masses in the right lobe of the liver and a metastasis in the left adrenal gland. He was referred after a percutaneous liver biopsy which revealed a moderately differentiated HCC. He was treated by TACE. At the third session of TACE, the right hepatic artery was found to be thrombosed; however, angiography also demonstrated collateral feeder vessels (arising from the pancreaticoduodenal artery) which were used for treatment. He developed necrotizing pancreatitis, possibly due to regurgitation of the chemotherapeutic agents to the pancreas. He recovered without complications with imipenem-cilastatin prophylaxis. Acute pancreatitis is a rare but severe complication of TACE. Selective catheterization of the tumor vessels is the established standard in TACE. A careful risk-benefit analysis is mandatory in patients with abnormal collateral vessels. Treatment of acute necrotizing pancreatitis (ANP) after TACE is the same as the accepted approach to ANP due to other causes.

Necrotizing pancreatitis is one of the rare complications of transcatheter arterial chemoembolization (TACE). Necrotizing pancreatitis after TACE may result from the development of ischemia caused by regurgitation of embolic materials into the vessels supplying the pancreas. We report a case of post-TACE necrotizing pancreatitis with abscess formation in a patient with hepatocellular carcinoma. The patient had suffered hepatic artery injury due to repetitive TACE; during his 25th TACE procedure he had submitted to selective catheterization of the feeding vessel from the dorsal pancreatic artery with a cytotoxic agent and Gelfoam particles. The patient complained of abdominal pain after the TACE procedure, and a CT scan led to a diagnosis of necrotizing pancreatitis with abscess formation. The pancreatic abscess progressed despite general management of the pancreatitis, including antibiotics. Percutaneous catheter drainage was performed, and the symptoms of the patient improved.

The purpose of this study was to prospectively compare the efficacy and controllability of pushable coil and detachable coil during embolization of gastroduodenal artery (GDA) while performing percutaneous implantation of port-catheter system for hepatic artery infusion chemotherapy. Fifty patients (M:F = 42:8, age: 31-81 years) with advanced hepatocellular carcinoma undergoing port-catheter system implantation were randomized into pushable coil group and detachable coil group. During catheter fixation, GDA was embolized as close to the origin as possible. Success rate, number of coils used, number of coils removed due to malposition after deployment, time to occlusion, uncoiled GDA length, pushability, and complications were compared. Pushability was graded as no tension, slight tension, and difficult to advance. Embolization was successful in 49 patients. One failure resulted from repeated regurgitation of pushable coil into hepatic artery. Number of coils used and removed coils, time to occlusion, and uncoiled GDA length were 1-3 (mean 2.32), 5 coils in 3 patients, 4-20 min (mean 8.00), and 0-15.0 mm (mean 3.36) in pushable coil group, and 1-5 (mean 2.12), 2 coils in 2 patients, 2-15 min (mean 7.40), and 0-10.2 mm (mean 2.92) in detachable coil group, respectively, without significant difference. Pushability was no tension (n = 24) and slight tension (n = 1) in pushable coil group and no tension (n = 16), slight tension (n = 7), and difficult to advance (n = 2) in detachable coil group. One hepatic artery dissection occurred in the failed case during coil removal. Pushable coils and detachable coils had similar efficacy and controllability during GDA embolization, although there was a trend favoring detachable coil.

Diaphragmatic herniation is an uncommon complication in the postquirurgic follow of the liver transplant. The associated symptoms are unspecific and may not suggest the correct diagnosis. It may explain why in many patients the diagnosis remains unmade or it is made only after a long interval of time. We present the case of a fifty-seven-year-old male who required an orthotopic liver transplant in 2010 due to a trifocal hepatocarcinoma. In postoperatory follow-up the patient showed alimentary regurgitation, vomiting, and dyspepsia. The diagnosis was made by an oesophagogastroduodenal transit with barium and an abdominal CT scan that showed a left diaphragmatic herniation with the gastric fundus into the thorax. With these findings we decided to perform a programmed surgery. After takedown of adhesions and replacement of the stomach into the upper abdomen, the palm-sized diaphragmatic opening was closed with a synthetic material. The patient's condition remained stable throughout the entire operation. The postoperative course was uneventful and he was discharged at the fifth day after surgery with a normal digestive intake. In a 12-month follow-up the patient shows no symptoms.

Adults with congenital heart disease who underwent the Fontan operation to palliate single ventricle heart defects-by direct connection of caval venous return to the pulmonary circulation-have improved survival due to advancements in surgical and interventional techniques. However, cardiac and non-cardiac comorbidities often coexist, complicating management, and contributing to premature morbidity and mortality. Cardiac issues include heart failure symptoms related to systolic and diastolic dysfunction, atrial and ventricular arrhythmias and systemic atrioventricular valve regurgitation. Structural issues may be related to obstruction of the Fontan pathway, or to branch pulmonary artery stenosis, both of which exacerbate symptoms. Non-cardiac complications in adults involve hepatic congestion, fibrosis and cirrhosis, hepatocellular carcinoma, chronic kidney disease, stroke, venous stasis, lymphatic issues and involvement of other organ systems. 'Fontan failure' refers to circulatory dysfunction, either cardiac, non-cardiac, or both, diagnosed after exclusion or treatment of reversible contributors such as structural issues and arrhythmias. Counselling about reproductive health, mental health, perioperative management and overall wellness are paramount for patients' well-being. Fontan patients are typically managed in highly specialised adult congenital heart centres, but may present to cardiologists or other practitioners with cardiac and non-cardiac emergencies or urgencies, sometimes after being out of care. In this review, we discuss the management of the adult Fontan patient, including surveillance, cardiac and non-cardiac complications, reproductive health, and advanced therapies.

Cardiac tumors are relatively rare. Secondary cardiac tumors are by far more common than primary cardiac tumors. Cardiac involvement may occur secondary to hematogenous metastases, direct invasion, or tumor growth into the venous system and extension into the right atrium. Patients can present with a spectrum of conditions, including embolization, obstruction of ventricular outflow tracts, direct invasion of myocardium causing impaired myocardial function, invasion of surrounding tissue, interference with valvular function causing valvular regurgitation, or constitutional non-specific signs and symptoms. Imaging modalities are essential for diagnosis. Management is mostly surgical, but can include other medical strategies as well. We present a case of a 65-year-old male with hepatocellular carcinoma with direct invasion to the heart through the venous system.
