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.
