چکیده
BACKGROUND Portal vein embolization is an accepted procedure that provides hypertrophy of the future remnant liver in order to reduce post-hepatectomy complications. AIM To present a series submitted to portal vein embolization using an adapted hysterosalpingography catheter via transileocolic route. METHODS Were performed right portal branch embolization in 19 patients using hysterosalpingography catheter. For embolizing the vessel, was used Gelfoam(r) powder with absolute alcohol solution. Indications for hepatectomy were colorectal liver metastases in all cases. RESULTS An adequate growth of the future remnant liver was achieved in 15 patients (78.9%) and second time hepatectomy could be done in 14 (73.7%). In one patient (5.2%), tumor progression prevented surgery. One patient presented acute renal failure after portal embolization. CONCLUSIONS The hysterosalpingography catheter is easy to handle and can be introduced into the portal vein with a wire guide. There were no major post-embolization complication. Its use is safe, cheap and effective.

Hepatic outflow obstruction created by balloon occlusion of the hepatic vein induces characteristic angiographic findings in the occluded area: prolonged enhancement on hepatogram followed by reversed portal opacification on the hepatic arteriogram and perfusion defect on the arterial portogram. The following induced hepatic hemodynamic changes are suggested: hepatic arterial flow increases, an...

Background Portal vein thrombosis (PVT) is one of the most common causes of extrahepatic portal hypertension in children, which may follow neonatal umbilical vein catheterization. The incidence rates of catheter-related PVT, in infants and children vary in different studies.

To determine whether PHEMA [poly(2-hydroxyethylmethacrylate)] is suitable for portal vein embolization in patients scheduled to right hepatectomy and whether it is as effective as the currently used agent (a histoacryl/lipiodol mixture). Two groups of nine patients each scheduled for extended right hepatectomy for primary or secondary hepatic tumor, had right portal vein embolization in an effo...
