[Hemodynamic depression in carotid artery stent without angioplasty].

Introduction: Hemodynamic depression is a frequent complication related to carotid artery stenting with angioplasty. The aim of this study was to assess our results regarding hemodynamic depression, in patients who underwent carotid artery stenting without angioplasty.

Patients And Methods: Between October 2002 and April 2010, 261 carotid stenosis (in 242 patients) were treated with the use of self-expanding stents without angioplasty.

Maximal curvature-based segmentation of 3D vessel contours.

The segmentation of three-dimensional vascular trees is an important topic in medical image processing. Although it may seem to be an easy task, many different techniques have been proposed in the literature during the last decade and many difficulties remain. One can wonder why the human eye is usually able to understand the connectivity and the topology of the different structures while most algorithms fail to do so.

The role of a specialized approach for patients with diabetes, critical ischaemia and foot ulcers not previously considered for proactive management.

Aims: To analyse the outcome of the proactive management of patients with diabetes, critical limb ischaemia and foot ulcers using percutaneous transluminal angioplasty as the only vascular procedure and adjuvant conservative surgery when indicated.

Methods: A retrospective study of patients with diabetes included in our database who sought a second opinion in our unit and met the following criteria: foot ulcer and critical limb ischaemia in patients for whom any proactive vascular treatment had not previously been considered by other teams.

Results: Twenty patients underwent endovascular procedures.

In-hospital complications and mortality following major lower extremity amputations in a series of predominantly diabetic patients.

The purpose of this study was to analyze the outcomes of major lower extremity amputations (MLEAs) in a series, including diabetic patients, with the aim to study whether diabetes mellitus is a risk factor of in-hospital mortality and perioperative complications. A retrospective analysis of 283 MLEAs (221 of these patients were diabetic and 62 were nondiabetic) performed between January 1, 1998, and December 31, 2008, at the General Surgery Department and Diabetic Foot Unit of La Paloma Hospital in Las Palmas de Gran Canaria (Canary Islands) was done. The significant risk factors of mortality were >" xbd="324" xhg="301" ybd="1481" yhg="1446"/>75 years of age (odds ratio [OR] = 4.

[Ultrasonographic histological study on the evolution of a canine model of hormone-induced benign prostatic hyperplasia].

Introduction: Despite exhibiting histological differences from the human process, canine hormone-induced benign prostatic hyperplasia (BPH) is still the most widely used animal model for evaluating treatment strategies.

Objectives: The aim of this study is to determine the optimal moment for starting a therapeutic trial in this animal model.

Material And Methods: Six male beagle dogs over one year of age were used in this study.
