Micro-implant d'acétonide de fluocinolone (ILUVIEN(®)) pour l'oedème maculaire diabétique chronique [Fluocinolone acetonide (ILUVIEN®) micro-implant for chronic diabetic macular edema].

Diabetic macular edema (DME) is a frequent complication of diabetic retinopathy and may cause severe visual loss. In this article, we examine the pathophysiology of DME and review various treatment options, such as laser photocoagulation, anti-vascular endothelial growth factor (VEGF) receptor antibodies, and steroids including ILUVIEN(®), which is a new sustained-release, non biodegradable, injectable, intravitreal micro-implant containing fluocinolone acetonide. The results of the FAME (Fluocinolone Acetonide in Diabetic Macular Edema) studies, conducted to evaluate the efficacy and safety of ILUVIEN(®) in DME, are discussed

Extrahepatic Portal Hypertension following Liver Transplantation: a Rare but Challenging Problem

This study reports our experience of 8 cases of extrahepatic portal hypertension after 273 orthotopic liver transplantations in 244 adult patients over a 10- year period. The main clinical feature was ascites, and the life-threatening complication was variceal bleeding. Extrahepatic portal hypertension was caused by portal vein stenosis in 6 patients, and left-sided portal hypertension in 2 patients after inadventent ligation of portal venous tributaries or portasystemic shunts. All patients with portal vein stenosis had complete relief of portal hypertension after percutaneous transhepatic venoplasty (n=4) or surgical reconstruction (n=2), after a median follow-up of 33 (range: 6–62) months. Of the 2 patients with left-sided portal hypertension, one died after splenectomy and one rebled 6 months after left colectomy. This study suggests that extrahepatic portal hypertension is a series complication after liver transplantation that could be prevented by meticulous portal anastomosis and closure of portal tributaries or portasystemic shunts to improve the portal venous flow. However, any ligation has to be performed under ultrasound guidance to avoid inadventent venous ligations
