- Development of a canine model with diffuse hepatic vein obstruction (Budd‑Chiari syndrome) via endovascular occlusion.
- Shen B, Zhang Q, Wang X, Xu H, Zu M, Wu M, Gao Z, Wang W, Xiao J, Wang Y.Author information Department of Interventional Radiology, The Affiliated Hospital of Xuzhou Medical College, Xuzhou, Jiangsu 221006, P.R. China.AbstractThe aim of the present study was to develop a reliable and reproducible canine model to mimic human diffuse hepatic vein obstruction (Budd‑Chiari syndrome, BCS). A total of 24 canines were divided into an experimental (n=18) and a control (n=6) group. Under the guidance of digital subtraction angiography, a balloon catheter was delivered to the target hepatic vein (the common trunk of the left hepatic and middle hepatic veins) via the right external jugular vein. The balloon was inflated to completely block the vessels. For the canines in the experimental group, a mixture of N‑butyl‑cyanoacrylate (NBCA) and lipiodol (3‑5 ml) was injected via the balloon catheter. Canines in the control group were injected with equal volumes of normal saline. Liver function and pathology were examined at 4, 6 and 8 weeks following surgery. BCS was successfully established in all members of the experimental group and there were no serious complications in either group. The left and middle hepatic veins and common trunk were completely obstructed at 4, 6 and 8 weeks following surgery in the experimental group, while in the control group, the hepatic vein remained unobstructed at 4 weeks. There was hepatocyte congestion and edema at 4 weeks following surgery in the experimental group and the edema became aggravated following 6 weeks. At 8 weeks following surgery, there was necrosis of hepatocytes and significant thickening of the hepatic vein tunica intima in addition to an increased number of elastic fibers. In conclusion, the present study demonstrates that a reliable and reproducible canine model of BCS can be developed by endovascular obstruction of the hepatic vein.

- Hepatic arterial infusion chemotherapy by the fixed-catheter-tip method: retrospective comparison of percutaneous left subclavian and femoral port-catheter system implantation.
- Matsumoto T, Yamagami T, Yoshimatsu R, Morishita H, Kitamura N, Sato O, Hasebe T.Author information 1 Department of Diagnostic Radiology, Japanese Red Cross Kyoto Daiichi Hospital, Kyoto, Japan.AbstractOBJECTIVE. The purpose of this study was to retrospectively compare the subclavian and femoral approaches to a fixed-catheter-tip method of implantation of a port-catheter system for hepatic arterial infusion chemotherapy with respect to complications and dysfunctions. MATERIALS AND METHODS. Between April 2006 and April 2012, 153 patients (104 men, 49 women; age range, 23-82 years; mean, 65 years) with unresectable malignant liver tumors underwent percutaneous implantation of indwelling port-catheter systems by the fixed-catheter-tip method via the left subclavian or femoral artery. The success of implantation and outcome of complications were investigated and compared between these approach routes. RESULTS. The overall technical success rate of port-catheter system implantation with the fixed-catheter-tip method was 99% (152 of 153 patients). Seventy-five patients underwent implantation with a port-catheter system via the left subclavian artery, and 77 patients via the femoral artery. Catheter dislocation occurred in 3.9% of the patients; hepatic artery obstruction, 2.6%; catheter occlusion, 3.9%; bleeding at the puncture site, 3.9%; cerebral infarction, 1.3%; and infection related to port-catheter implantation, 2.6%. No significant differences in complications and port-catheter system dysfunction between the left subclavian and femoral approaches to port-catheter system implantation with the fixed-catheter-tip method were seen in any of the parameters. In addition, cerebral infarction occurred exclusively with the left subclavian approach, whereas infection occurred exclusively with the femoral approach. CONCLUSION. Implantation of the port-catheter system with the fixed-catheter-tip method is equally feasible via both the left subclavian and the femoral approaches.
