Background: Ablation of the vein of Marshall (VOM) by dehydrated ethanol (DE) is an important method for completely blocking the mitral isthmus (MI). Before DE ablation of the VOM, Marshall angiography should be performed so that the contrast medium is inevitably exposed to DE. Method:We present a case of DE ablation of the VOM. When iodixanol was exposed to DE, some floccule embolized the lumen of the over-the-wire (OTW) balloon dilatation catheter and led to the impossibility of DE ablation. Then, we performed in vitro experiments: iodixanol, not iomeprol, produced many stable white floccules when it encountered DE. Conclusion:Iodixanol is not an appropriate contrast for DE ablation of the VOM. However, if there is no other alternative contrast, the following methods might be used to address the problem: (1) diluted iodixanol (iodixanol:normal saline 1:1) could be used for VOM ablation; or (2) the lumen of the OTW could be flushed by NS after VOM angiography, and then DE injection could be performed.

Post-operative depletion of platelet count is associated with anastomotic insufficiency following intrahepatic cholangiojejunostomy: a case–control study from the results of 220 cases of intrahepatic cholangiojejunostomy

BackgroundPost-operative anastomotic insufficiency following major hepato-biliary surgery has significant impacts on the post-operative course. Recent reports have revealed that platelets play an important role in liver regeneration and wound healing. From these experimental and clinical results on platelet function, we hypothesized that post-operative platelet depletion (to <10 × 104/μL) would be associated with delayed liver regeneration as well as anastomotic insufficiency of intrahepatic cholangiojejunostomy. However, little information is available regarding correlations between platelet count and these complications. The purposes of the present study were, firstly, to evaluate the incidence of anastomotic insufficiency following intrahepatic cholangiojejunostomy and, secondly, to evaluate whether platelet depletion represents a risk factor for anastomotic insufficiency in intrahepatic cholangiojejunostomy.MethodsParticipants in this study comprised 220 consecutive patients who underwent intrahepatic cholangiojejunostomy following hepato-biliary resection for biliary malignancies between September 1998 and December 2010. Anastomotic insufficiency was confirmed by cholangiographic demonstration of leakage from the anastomosis using contrast medium introduced via a biliary drainage tube or prophylactic drain placed during surgery.ResultsAnastomotic insufficiency of the intrahepatic cholangiojejunostomy occurred in 13 of 220 patients (6%). Thirteen of the 220 patients, including one with anastomotic insufficiency, died during the study. Uni- and multivariate analyses both revealed that platelet depletion on post-operative day 1 (<10 × 104/μL) correlated with anastomotic insufficiency.ConclusionPost-operative platelet depletion was closely associated with anastomotic insufficiency following intrahepatic cholangiojejunostomy. This correlation has been established, but the underlying mechanisms have not.

Usefulness of portography and contrast-enhanced computed tomography to predict the embolized area in percutaneous transhepatic portal vein embolization with absolute ethanol under temporary balloon occlusion

Abstract: The distribution of AE is different from that of contrast medium in percutaneous transhepatic RPVE under TBO. The pre-treatment measurement of the angles of portal branches against the horizontal plane on CECT is suggested to be useful for predicting the embolized area.
