A Rabbit Model for Selective Portal Vein Embolization

Journal of Surgical Research, 2011
Portal vein embolization (PVE) is a technique to increase future remnant liver volume. A standardized animal model, resembling the clinical PVE procedure, is needed to clarify some of the unresolved issues surrounding PVE. For this purpose we developed a new rabbit model for PVE.Twenty female New Zealand white rabbits were allocated to two protocols ...

[Portal vein embolization: Present and future].

Bulletin du cancer, 2017
Portal vein embolization consists of occluding a part of the portal venous system in order to achieve the hypertrophy of the non-embolized liver segments. This technique is used during the preoperative period of major liver resection when the future remnant liver (FRL) volume is insufficient, exposing to postoperative liver failure, main cause of death

Transileocolic Portal Vein Embolization

2011
Transileocolic portal vein embolization (TIPE) is invasive compared to percutaneous transhepatic portal vein embolization (PTPE) because the procedure requires general anesthesia. There are, however, several advantages: First, it enables the examination of extrahepatic diseases; second, catheter manipulation is easier compared to ipsilateral PTPE ...

Preoperative Portal Vein Embolization

2007
Curative treatment of hilar cholangiocarcinoma leads to a major reduction of hepatic function due to the need for extended hepatectomy with biliary tract resection; therefore, it is exposed to the risk of postoperative hepatic failure [1,2]. Makuuchi [3] can take the credit, for introducing preoperative embolic occlusion of portal branches (PVE) in ...

Sonographic diagnosis of gas embolism in the portal vein

Gastrointestinal Radiology, 1982
A case of gas embolism in the portal vein detected by ultrasound is presented. Gas bubbles were characterized by strong reflections in the lumen of the portal vein, moving into the liver. Because they were trapped in the liver parenchyma, the gas bubbles caused strongly echogenic areas, sometimes with acoustic shadows.

Complications of Portal Vein Embolization

2011
Portal vein embolization (PVE) may be viewed as a tool used to improve the morbidity and mortality following major hepatectomy. While it is considered relatively safe, PVE is a complex procedure with potential complications. Adverse events may relate to the access approach or to the embolization procedure itself.

Indications for portal vein embolization in perihilar cholangiocarcinoma

Journal of Hepato-Biliary-Pancreatic Sciences, 2014
Abstract Preoperative portal vein embolization (PVE) is often performed as a routine procedure before extended hepatectomy to minimize postoperative liver failure. However, the indications for PVE in perihilar cholangiocarcinoma (PCCA), which differ between institutions, remain controversial. In the present study, we examined the indications for PVE in

Embolic Materials Used for Portal Vein Embolization

2011
The gamut of embolic materials has been used for portal venous embolization. Local preferences appear to dictate the choice of embolic material, as there are no clear data supporting a superior choice among absolute ethanol, cyanoacrylate, fibrin glue, and small particle embolization with or without coils – the techniques accounting for the majority of

Portal Vein Embolization: Efficacy, Methodology, and Alternatives

Techniques in Vascular and Interventional Radiology
Portal vein embolization (PVE) is a minimally invasive intervention that has become the standard of care in preoperative liver augmentation for patients undergoing extended hepatic resections for primary and secondary liver cancers. PVE provides permanent and complete occlusion of the portal venous inflow to diseased hepatic segments, re-directing ...
