[Percutaneous aortic valve replacement by trans-carotid approach: First case in Chile].

The indication for percutaneous aortic valve implantation (TAVI) has increased considerably in recent years, preferably using transfemoral access (TF); however, it is not clear which should be the preferred access in the event of contraindications to the latter. We present an 81-year-old patient with high surgical risk in whom a 50% obstruction of the descending aortic lumen was identified and so, a left transcarotid access was chosen. Numerous alternative approaches to the TF approach have been described in recent years.

PRospective Observational Registry Evaluating the Safety and Effectivenessof Orsiro Stent in Chilean Patients - ROSES Registry.

Background: There is little information on the performance of the new generation of stents with bioabsorbable polymers in the Latin American population. This registry aimed to further validate the safety and efficacy of the Orsiro bioresorbable-polymer sirolimus-eluting stent (BPSES) in unselected patients undergoing percutaneous coronary intervention (PCI) in Chilean centers.

Methods: We prospectively enrolled patients undergoing PCI with BPSES in 6 Chilean centers.

Cemented Dual Mobility Cup for Primary Total Hip Arthroplasty in Elder Patients with High-Risk Instability.

Several studies have shown that double mobility (DM) cups reduce postoperative dislocations. Does the cemented dual mobility cup reduce dislocations in a specific cohort of elder patients with a high dislocation risk? Our hypothesis is that this implant is optimal for elder patients because it reduces early dislocation. We have retrospectively reviewed elder patients who underwent total hip arthroplasty (THA) with cemented double mobility cup between March 2009 and January 2018.

Mechanical barriers and transforming growth factor beta inhibitor on epidural fibrosis in a rabbit laminectomy model.

Background: TGF-β has been described as a mediator of fibrosis and scarring. Several studies achieved reduction in experimental scarring through the inhibition of TGF-β. Fibroblasts have been defined as the cell population originating fibrosis, blocking fibroblast invasion may impair epidural fibrosis appearance.

[Metal artifact reduction in post-operative spinal imaging using image acquisition protocol in multidetector computed tomography scans. Cohort study].

Background: In postoperative patients with metallic implants, CT scans can become less effective due to metal-related arti-facts. The purpose of our study was to evaluate the effectiveness of a specific metal artifact reduction image protocol, in order to reduce the metal artifact caused by titanium pedicular screws in patients undergoing lumbar pathology by lumbar fusion. This enables surgeons to make an accurate diagnosis of the exact placement of inserted pedicle screws, making this the preferred image modality for assessing screw position after surgery.

Model of induced leakage of polymethylmethacrilate inside epidural space and prevertebral muscles during vertebroplasty in pigs: clinical, macroscopical, and histological study.

Study Design: Experimental study in animals.

Purpose: Study the clinical behavior of animals after an induced leakage of cement during vertebroplasty in pigs. Study the distribution of polymethylmetacrilate inside the epidural space and prevertebral muscle.

Infected vertebroplasty due to uncommon bacteria solved surgically: a rare and threatening life complication of a common procedure: report of a case and a review of the literature.

Study Design: Case report.

Objective: The aim of this work is to describe a case of infected vertebroplasty due to uncommon bacteria solved surgically with 2 years of follow-up and to discuss 6 other cases found in literature.

Summary Of Background Data: Vertebroplasty is a well-known and useful technique for the treatment of painful osteoporotic vertebral fractures.

[Survival of diabetic patients with known coronary artery disease].

Background: The risk of cardiovascular diseases is two to four times higher in diabetic patients.

Aim: To study the severity of coronary disease and survival of patients with diabetes mellitus, compared to matched controls without diabetes.

Patients And Methods: A retrospective review of all coronary angiographies performed at a private hospital.
