Management of Bleeding Duodenal Varices with Combined TIPS Decompression and Trans-TIPS Transvenous Obliteration Utilizing 3% Sodium Tetradecyl Sulfate Foam Sclerosis.

Objectives: Endoscopic experience in the management of duodenal varices (DVs) is limited and challenging given the anatomic constraints and limited experience. The endovascular management of DVs is not yet established and the controversy of whether to manage them by decompression with a transjugular intrahepatic portosystemic shunt (TIPS) or by transvenous obliteration is unresolved. In the literature, the 6-12 month rebleeding rate of DVs after TIPS is 21-37% and after transvenous obliteration is 13%.

Management of stomal varices with transvenous obliteration utilizing sodium tetradecyl sulfate foam sclerosis.

The management of parastomal varices is not established. Transjugular intrahepatic portosystemic shunt (TIPS) creation is the most commonly described treatment; however, the rebleed rate after TIPS is 21-37%. The purpose of the study is to determine the effectiveness of transvenous obliteration using sodium tetradecyl sulfate (STS) and to describe a new simplified technique in obliterating these varices.

Protective value of TIPS against the development of hydrothorax/ascites and upper gastrointestinal bleeding after balloon-occluded retrograde transvenous obliteration (BRTO).

Objectives: The objective of this study was to evaluate the incidence of post-balloon-occluded retrograde transvenous obliteration (BRTO) ascites/hepatic hydrothorax and rebleeding rate (variceal and non-variceal) in the presence and absence of a transjugular intrahepatic portosystemic shunt (TIPS).

Methods: A retrospective audit of consecutive patients undergoing BRTO was performed (August 2007-October 2010). The population was divided into two groups: patients who underwent BRTO only (BRTO-only group) and those who underwent BRTO in the presence of TIPS (BRTO+TIPS group).

Ectopic varices: anatomical classification, hemodynamic classification, and hemodynamic-based management.

Ectopic varices are dilated splanchnic (mesoportal) veins/varicosities and/or are dilated portosystemic collaterals that can occur along the entire gastrointestinal tract outside the common pathologic variceal sites. Ectopic varices are complex and highly variable entities that are not fully understood. Ectopic varices represent 2%-5% of a gastrointestinal tract variceal bleeding.

The effect of balloon-occluded transvenous obliteration of gastric varices and gastrorenal shunts on the hepatic synthetic function: a comparison between Child-Pugh and model for end-stage liver disease scores.

Purpose: To evaluate the effect of balloon-occluded transvenous obliteration (BRTO) on the model for end-stage liver disease (MELD) and the Child-Pugh (C-P) score and their individual components.

Methods: A retrospective review of patients undergoing only BRTO without transjugular intrahepatic portosystemic shunt was performed (08, 2007 to 06, 2010). Pre- and post-BRTO MELD and C-P scores were calculated.

Balloon-occlusion catheter rupture during balloon-occluded retrograde transvenous obliteration of gastric varices utilizing sodium tetradecyl sulfate: incidence and consequences.

Balloon-occluded retrograde transvenous obliteration (BRTO) is an established procedure for the management of bleeding gastric varices in Asia. Invariably, the sclerosant utilized in Asia is ethanolamine oleate and the inventory used (vascular sheaths, balloon-occlusion catheters, and microcatheters) is not available outside Asia. A total of 41 BRTO procedures were performed with a technical and obliterative (gastric varix obliteration) success rate of 95% (n = 39 of 41) and 85% (n = 35 of 41), respectively.

Extrahepatic pseudoaneurysms and ruptures of the hepatic artery in liver transplant recipients: endovascular management and a new iatrogenic etiology.

Purpose: To characterize extrahepatic pseudoaneurysm regarding incidence and etiology and determine the effectiveness of endovascular management.

Methods: A retrospective audit of 1,857 liver transplants in two institutions was performed (1996-2009). Recipients' demographics, clinical presentation, transplant type, biliary anastomosis, and presence of biliary endoprostheses were noted.

Prevalence, presentation, and endovascular management of hemodynamically or clinically significant arterio-portal fistulae in living and cadaveric donor liver transplant recipients.

Purpose: To compare the prevalence (cadaveric vs. living donor transplants), clinical features, and the effectiveness of endovascular management of significant arterio-portal fistulae (APF) in liver transplant recipients.

Methods: A retrospective audit of liver transplant recipients in two institutions was performed (1996-2009).
