Giant Symptomatic Aneurysm Secondary to Hereditary Hemorrhagic Telangiectasia of a Main Hepatic Artery with Aberrant Origin in Superior Mesenteric Artery.

Background: Hereditary hemorrhagic telangiectasia (HHT) is a rare disease consistent in vascular dysplasias affecting different organs. Liver involvement includes telangiectases, arteriovenous shunting, and ischemic cholangitis, and its prevalence ranges from 8% to 31%. Spontaneous pseudoaneurysms have never been reported associated to HHT.

Comparison of Bypass with Endoscopically Harvested Internal Saphenous Vein versus Bypass with Surgically Harvested Internal Saphenous Vein for Lower Limb Arterial Disease.

Background: Patients with lower limb arterial disease have a high risk for complications related with surgical wounds. The endoscopic extraction of the great saphenous vein (GSV) is a less invasive alternative to the conventional surgical extraction.

Methods: A clinical and ultrasonographic follow-up was carried out on the lower limb bypass with GSV performed in our institution between years 2007 and 2012.

Retroperitoneal fibrosis: single-centre experience from 1992 to 2010, current status of knowledge and review of the international literature.

Objective: The aims of this study were to investigate retroperitoneal fibrosis in a Spanish hospital and present a review of the international literature to attempt to elucidate a diagnostic and therapeutic approach to this unusual pathology.

Material And Methods: A database search was performed in the pathology department and in the documentation service using the key words "retroperitoneal fibrosis" and "Ormond's disease", limiting the search to the years 1990-2010. Cases in which secondary retroperitoneal fibrosis was considered were excluded.
