Type III B endoleak leading to aortic rupture after endovascular repair: analysis of errors in follow up and treatment.

Background: The aim of this paper is to describe the case of a patient with a type III endoleak which was misdiagnosed and treated without success as a type I-II endoleak. An incorrect endoleak diagnosis lead to aortic rupture, which could be avoided with a correct diagnosis. Type III B endoleaks presents some diagnostic difficulties, in the case we describe, they were increased by late presentation and poor follow up.

An update in varicose vein pathology after ten years of endovenous laser therapy (EVLT) with a 980 nm diode laser: clinical experience of a single center.

Aim: To show our experience in the surgical treatment of superficial vein insufficiency of the lower limbs.

Subjects And Methods: Since 2002 we have performed 659 procedures of endovascular laser therapy (EVLT) (group A) in the treatment of chronic venous insufficiency of the great saphenous vein using a 980 nm diode laser. A closely matched group of 100 patients (50 Group A, 50 Group B) with homogeneous clinical findings (CEAP classification) was controlled with a mean follow-up of 18 months in our more recent experience (3 years).

Impaired plasma nitric oxide availability and extracellular superoxide dismutase activity in healthy humans with advancing age.

This study is aimed to verify the modifications of extracellular superoxide dismutase (EC-SOD) activity and its potential involvement on the mechanism responsible for the impairment of plasma nitric oxide (NO) availability occurring with advancing age in healthy humans. For this purpose, plasma samples were drawn from 40 healthy men, aged 20-92 years, in fasting state and used for measurements of stable end-product nitrite/nitrate (NOx), as expression of NO availability, EC-SOD activity, thiobarbituric acid reactive substances (TBARS) as marker of lipid peroxidation, Trolox equivalent antioxidant capacity (TEAC) as a measure of plasma total antioxidant capacity, and in vitro susceptibility of low density lipoprotein (LDL) to copper-mediated oxidation, evaluated as lag time. As indicated by our results, advancing age was significantly related to decreased plasma values of NOx (r = -0.
