Escleroterapia endoscópica asistida mediante balón oclusivo como tratamiento de varices gástricas cardiofúndicas de alto riesgo: reporte de dos casos y revisión de la literatura

Rev. méd. Chile; 145 (10), 2017
Management of gastrointestinal bleeding caused by fundal varices is particularly difficult to manage. The options are: transjugular intrahepatic portosystemic shunt (TIPS), endoscopic injection of cyanoacrylate or balloon-occluded retrograde transvenous obliteration (BRTO). We report a 63 year-old male w...

Local and systemic effects of fibrin and cyanoacrylate adhesives on lung lesions in rabbits

Clinics; 72 (10), 2017
OBJECTIVES: Tissue adhesives can be used to prevent pulmonary air leaks, which frequently occur after lung interventions. The objective of this study is to evaluate local and systemic effects of fibrin and cyanoacrylate tissue adhesives on lung lesions in rabbits. METHODS: Eighteen rabbits were submitte...

Comparison of short-segment monoaxial and polyaxial pedicle screw fixation combined with intermediate screws in traumatic thoracolumbar fractures: a finite element study and clinical radiographic review

Clinics; 72 (10), 2017
OBJECTIVES: No studies have compared monoaxial and polyaxial pedicle screws with regard to the von Mises stress of the instrumentation, intradiscal pressures of the adjacent segment and adjacent segment degeneration. METHODS: Short-segment monoaxial/polyaxial pedicle screw fixation techniques were compa...

The effect of hard tissue surgical changes on soft tissue displacement: a pilot CBCT study

ABSTRACT Introduction: This pilot study had as main objective to test the reliability of a new method to evaluate orthognathic surgery outcomes and also, to understand the effect of hard tissue changes on soft tissue displacement. Methods: The sample consisted of eight patients that underwent bimaxill...

Minimally Invasive Epicardial Pacemaker Implantation in Neonates with Congenital Heart Block

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Few studies have characterized the surgical outcomes following epicardial pacemaker implantation in neonates with congenital complete atrioventricular block (CCAVB). Objective: This study sought to assess the long-term outcomes of a minimally invasive epicardial approach using a su...

Non-Sustained Ventricular Tachycardia Episodes Predict Future Hospitalization in ICD Recipients with Heart Failure

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Implantable cardioverter-defibrillator (ICD) therapy is well known to reduce mortality in selected patients with heart failure (HF). Objective: To investigate whether monitored episodes of non-sustained ventricular tachycardia (NSVT) might predict future HF hospitalizations in ICD ...

Impact of Paclitaxel-Eluting Balloons Compared to Second-Generation Drug-Eluting Stents for of In-Stent Restenosis in a Primarily Acute Coronary Syndrome Population

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: The place of drug-eluting balloons (DEB) in the treatment of in-stent restenosis (ISR) is not well-defined, particularly in a population of all-comers with acute coronary syndromes (ACS). Objective: Compare the clinical outcomes of DEB with second-generation drug-eluting stents (DE...

Do We Need to Personalize Renal Function Assessment in the Stratification of Patients Undergoing Cardiac Surgery?

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: Renal dysfunction is an independent predictor of morbidity and mortality in cardiac surgery. For a better assessment of renal function, calculation of creatinine clearance (CC) may be necessary. Objective: To objectively evaluate whether CC is a better risk predictor than serum cre...

Prevalence and Prediction of Obstructive Coronary Artery Disease in Patients Undergoing Primary Heart Valve Surgery

Arq. bras. cardiol; 109 (4), 2017
Abstract Background: The prevalence of coronary artery disease (CAD) in valvular patients is similar to that of the general population, with the usual association with traditional risk factors. Nevertheless, the search for obstructive CAD is more aggressive in the preoperative period of patients with va...
