  • Dural arteriovenous fistula (DAVF) of the transverse sinus with ophthalmic manifestations in young children are rare. We reviewed two cases of direct AVF of the transverse sinus with ocular manifestations managed at our institution. The first, a 2.5 years old male child presented with left exophthalmos. Angiography revealed AVF between the occipital artery and the transverse sinus. The second, a 2 years old female child, complained of left exophthalmos. Imaging studies showed bilateral direct AVFs of the transverse sinus with bilateral dysmaturation of the sigmoid sinus. Transarterial embolization was done in both cases. Clinical and radiological follow up revealed complete cure. This report suggests that DAVF of the transverse sinus supplied by the external carotid branches can present with ophthalmic manifestations especially if there is distal venous stenosis or obliteration involving sigmoid sinus. Transarterial embolization using coils and liquid embolic agents could be safe and feasible to obliterate the fistula.

  • The authors present a case of isolated dural arteriovenous fistula (DAVF) in the transverse sinus, which developed six years after microvascular decompression caused by hemifacial spasm via suboccipital craniectomy. The lesion was successfully treated by transarterial embolization using Onyx. We reviewed the related radiologic and therapeutic features of DAVF involving an isolated sinus and described the feasibility of the use of Onyx.

  • The embolic effect of Gelfoam was investigated for transarterial embolization of renal artery (TAE-RA) in four normal rabbits. The catheter was selectively introduced into the unilateral renal artery under fluoroscopy and the Gelfoam-iohexol mixture was infused through a catheter into the renal arteries of 4 rabbits. The immediate and delayed (8 weeks) embolic effects on the renal arteries was investigated with selective angiography. The Gelfoam-iohexol was visualized under fluorosxopy in four rabbits. Renal arteries were ablated immediately after TAE-RA in four rabbits, however, opacification of renal parenchyma was visualized by injected contrast agent in 3 rabbits at 8 weeks. The Gelfoam-iohexol can be used as a short-term embolic materials for TAE-RA, however it is not adequate for permanent embolization of renal artery.

  • Background: Hepatocellular carcinoma (HCC) is one of the most prevalent malignancies worldwide. Transarterial chemoembolisation (TACE) is the standardized therapy for intermediate stage HCC. However, the prognosis for HCC patients treated by TACE greatly varies. Thus, there is a critical need for finding biomarkers to predict the prognosis of HCC patients. The amino acid transporter-2 (ASCT2) is involved in tumorigenesis and progression of many malignancies. This study aimed to evaluate the predictive role of two single nuclear polymorphisms (SNPs, rs3826793 and rs2070246) in the ASCT2 gene in HCC patients treated by TACE. Materials and Methods: Two functional SNPs (rs3826793 and rs2070246) in the ASCT2 gene were selected and genotyped using the Sequenom iPLEX genotyping system in a cohort of 448 unresectable Chinese HCC patients treated by TACE. Univariate and multivariate Cox proportional hazards models and Kaplan-Meier curves were used for the prognosis analyses. Results: There was no significant association between two SNPs (rs3826793 and rs2070246) in the ASCT2 gene and overall survival of TACE treated HCC patients. However, we demonstrated that patients with early stage HCC carrying T genotype in rs2070246 showed better OS than those carrying CC genotype (P=0.023). Conclusions: We demonstrated that patients with early stage HCC carrying T genotype in rs2070246 showed better OS than those carrying CC genotype.

  • Purpose: To evaluate efficacy of transarterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) in treatment of patients with hepatocellular carcinoma. Materials and Methods: During January 2009 to March 2012, 80 patients with hepatocellular carcinoma underwent TACE, with or without RFA. Alfafetoprotein (AFP) was checked before and after procedure. CT scans were obtained one month after TACE or RFA for all patients to evaluate tumor changes. Complete response+partial response+stable disease (CR+PR+SD)/n were used to assess the disease control rate (DCR). Survival at 3, 6 and 12 months was compared in both groups. Results: AFP levels in TACE + RFA group dropped rapidly, becoming obviously lower than that of the TACE group. In the TACE + RFA group DCR was 93.8%, while only 76.8% in the TACE group. The treatment effect between the two groups was statistically significant (P<0.05) by Ridit analysis. 1 year survival rate in the TACE + RFA group was 92.5%, significantly higher than that of the TACE group at 77.5% (P<0.05). Conclusions: TACE and RFA as combined therapy method for patients with middle and terminal stage HCC gives full play to synergy between the two and improves the therapeutic effect.

  • Background: A systematic review and meta-analysis were performed to compare the post-recurrence survival with hepatic re-resection versus transarterial chemoembolization (TACE) for recurrent hepatocellular carcinoma (HCC) after initial resection. Materials and Methods: All relevant papers were searched via PubMed, EMBASE, and Cochrane Library databases. Hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled using a random-effects model. Subgroup analysis was performed according to country. Sensitivity analysis was performed in studies which clearly reported the recurrent regions, in moderate/high-quality studies, in studies published in full-text form, and in studies published after 2005. Results: In total, twelve papers were included in our study. Five and seven of them were of moderate- and poor-quality, respectively. The overall meta-analysis demonstrated a statistically significantly higher post-recurrence survival in the hepatic re-resection group than in those undergoing TACE (HR=0.64, 95%CI=0.52-0.79, P<0.0001). Heterogeneity was statistically significant and statistical significance remained in the subgroup analysis. Sensitivity analyses were also consistent with the overall analysis. Conclusions: Hepatic re-resection might provide a better post-recurrence survival than TACE for recurrent HCC after initial resection. However, considering the low quality of published studies and the potential bias of treatment selection, further randomized trials should be warranted to confirm these findings.

  • Background: During the follow up period after transarterial embolization(TAE), cases of pulmonary metastasis were more prevalent in TAE-treated patients than in TAE-untreated patients. Therefore, a study was conducted to evaluate whether TAE increases the incidence of pulmonary metastasis of hepatocellular carcinoma and to clarify the risk factors for pulmonary metastasis. Methods: From March 1991 to March 1995, 156 patients who had been diagnosed with hepatocellular carcinoma by serology, and radiographic and histologic methods at Yeungnam University hospital were involved in this study. We excluded 12 patients with lung metastasis on initial diagnosis and the others. The remaining 144 patients had been followed up for at least 5 months and, divided into four groups according to lung metastasis and trans-arterial embolization treatment, and evaluated for age, sex, child-pugh score, liver cirrhosis, and level of AFP. Results: Pulmonary metastasis was found in 18.0% (26/144), of which 92.3%(24/26) and 7.7%(2/26) of the patients with and without transarterial chemoembolization, respectively. Of the patients, 23.5% (24/102) with TAE had lung metastais during follow-up periods and 4.7% (2/42) without TAE had lung metastasis. There was more likelihood for lung metastasis after TAE. but there was no difference between two groups in age, sex, child-pugh class, the presence of liver cirrhosis, and AFP. Conclusions: The incidence of pulmonary metastasis of hepatocellular carcinoma after TAE was higher. Child-pugh class was the only related clinical preciptating factors for pulmonary metastasis in TAE in our study. Our results suggest that regular chest X-ray check-ups may be more frequently needed by patients who had TAE treatment for hepatocellular carcinoma.

  • Purpose: This study was to test the effects of the positional change on low back pain, discomfort, and bleeding complications during the period of bed rest following transarterial chemoembolization (TACE). Methods: The research design for this study was a non-equivalent control group quasi-experimental design. The participants were 23 patients for the experimental group, and 23 patients for the control group. The experimental group received positional change of taking the semi-Fowler's position and the 30-degree lateral position alternatively during the period of bed rest after TACE for 4 hours at one-hour intervals. The control group maintained the supine position continuously during the period of bed rest after TACE. Results: There were statistically significant differences in low back pain and discomfort between the experimental and the control group after intervention. And no significant difference was found in bleeding complication between two groups. Conclusion: The results of the study suggest that the positional change is an effective nursing intervention to reduce low back pain and discomfort without increasing the risk of bleeding after TACE.
