BACKGROUND A congenital intrahepatic portosystemic shunt(IPSVS)is a rare vascular abnormality that is characterized by an anomalous intrahepatic venous tract that connects the intrahepatic portal vein with the hepatic venous system.Hepatic encephalopathy is an indication for IPSVS embolization,which is technically challenging because rapid blood flow through shunts can induce the migration of embolization material to systemic veins.This case report discusses the efficacy of percutaneous balloon-occluded retrograde transvenous obliteration for treating patients with IPSVSs.CASE SUMMARY A 75-year-old woman presented with a six-month history of repeated hepatic encephalopathy due to an IPSVS without liver cirrhosis.We successfully embolized the IPSVS using percutaneous balloon-occluded retrograde transvenous obliteration with interlocking detachable coils.After the procedure,the patient exhibited no symptoms of hepatic encephalopathy for 14 mo.CONCLUSION Balloon-occluded retrograde transvenous obliteration with detachable coils can be effective for the endovascular treatment of an IPSVS.

BACKGROUND Acute portal vein thrombosis(PVT)with bowel necrosis is a fatal condition with a 50%-75%mortality rate.This report describes the successful endovascular treatment(EVT)of two patients with severe PVT.CASE SUMMARY The first patient was a 22-year-old man who presented with abdominal pain lasting 3 d.The second patient was a 48-year-old man who presented with acute abdominal pain.Following contrast-enhanced computed tomography,both patients were diagnosed with massive PVT extending to the splenic and superior mesenteric veins.Hybrid treatment(simultaneous necrotic bowel resection and EVT)was performed in a hybrid operating room(OR).EVTs,including aspiration thrombectomy,catheter-directed thrombolysis(CDT),and continuous CDT,were performed via the ileocolic vein under laparotomy.The portal veins were patent 4 and 6 mo posttreatment in the 22-year-old and 48-year-old patients,respectively.CONCLUSION Hybrid necrotic bowel resection and transileocolic EVT performed in a hybrid OR is effective and safe.

AIM To evaluate the relationship between the location of hepatocellular carcinoma(HCC) and the efficacy of transarterial chemoembolization(TACE).METHODS We evaluated 115 patients(127 nodules), excluding recurrent nodules, treated with TACE between January 2011 and June 2014. TACE efficacy was evaluated according to m RECIST. The HCC location coefficient was calculated as the distance from the central portal portion to the HCC center(mm)/liver diameter(mm) on multiplanar reconstruction images rendered(MPR) to visualize bifurcation of the right and left branches of the portal vein and HCC center. The HCC location coefficient was compared between complete response(CR) and non-CR groups in Child-Pugh grade A and B patients.RESULTS The median location coefficient of HCC among all nodules, the right lobe, and the medial segment was significantly higher in the CR group than in the non-CR group in the Child-Pugh grade A patients(0.82 vs 0.62, P 0.05). On the other hand, in the Child-Pugh grade B patients, the HCC median location coefficient in each lobe and segment was not significantly different between in the CR and in the non-CR groups.CONCLUSION Improved TACE efficacy may be obtained for HCC in the peripheral zone of the right lobe and the medial segment in Child-Pugh grade A patients.

Hepatocellular carcinoma(HCC) is the sixth most common cancer and third leading cause of cancer-related death in the world. The Barcelona clinic liver cancer classification is the current standard classification system for the clinical management of patients with HCC and suggests that patients with intermediate-stage HCC benefit from transcatheter arterial chemoembolization(TACE). Interventional treatments such as TACE, balloon-occluded TACE, drug-eluting bead embolization, radioembolization, and combined therapies including TACE and radiofrequency ablation, continue to evolve, resulting in improved patient prognosis. However, patients with advanced-stage HCC typically receive only chemotherapy with sorafenib, a multi-kinase inhibitor, or palliative and conservative therapy. Most patients receive palliative or conservative therapy only, and approximately 50% of patients with HCC are candidatesfor systemic therapy. However, these patients require therapy that is more effective than sorafenib or conservative treatment. Several researchers try to perform more effective therapies, such as combined therapies(TACE with radiotherapy and sorafenib with TACE), modified TACE for HCC with arterioportal or arteriohepatic vein shunts, TACE based on hepatic hemodynamics, and isolated hepatic perfusion. This review summarizes the published data and data on important ongoing studies concerning interventional treatments for unresectable HCC and discusses the technical improvements in these interventions, particularly for advanced-stage HCC.

Purpose: The purpose of this retrospective study was to assess the incidence and the risk factors of contrast-induced nephropathy (CIN) following transcatheter arterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC). Materials and Methods: We performed a retrospective review of 186 sessions of TACE in 122 patients with HCC. We examined the incidence and factors associated with risk of CIN, defined as an increase of at least 0.5 mg/dl (44.2 μmol/l) or 25% of the baseline serum creatinine level between 48 and 72 hours after TACE. Results: CIN developed in 14 (7.5%) of the 186 sessions after TACE. A univariate analysis showed that the Child-Pugh class B or C [10/14 (71%) vs. 70/172 (41%), P = 0.046], a low albumin level (3.0 ± 0.5 vs. 3.4 ± 0.6, P = 0.018), and a low hemoglobin level (10.6 ± 2.0 vs. 11.8 ± 2.0, P = 0.035) were significantly associated with the development of CIN. Multivariate analysis revealed that the hemoglobin value was associated with CIN [odds ratio (OR) 1.6;P = 0.038]. Conclusions: CIN after TACE is closely associated with the severity of liver cirrhosis, and with low levels of albumin and hemoglobin. Effective preventive methods remain to be considered in patients with HCC and advanced LC who are undergoing TACE.
