Numerical studies were performed to investigate bone cement polymerization, temperature history and thermal osteonecrosis in cemented hip replacements with finite element methods. In this paper, the effects of pre-cooling and pre-heating of the prosthesis and/or the cement prior to implantation were simulated. It was found that the cement polymerization initiated near the bone-cement interface ...

Nowadays, interventions associated with the implantation of tracheal prostheses in patients with airway pathologies are very common. This surgery may promote problems such as migration of the prosthesis, development of granulation tissue at the edges of the stent with overgrowth of the tracheal lumen or accumulation of secretions inside the prosthesis. Among the movements that the trachea carri...

OBJECTIVES The purpose of this study was to evaluate the need for a permanent pacemaker after transcatheter aortic valve implantation with the CoreValve prosthesis (Medtronic, Inc., Minneapolis, Minnesota) using the new Accutrak delivery system (Medtronic, Inc.). BACKGROUND The need for a permanent pacemaker is a recognized complication after transcatheter aortic valve implantation with the C...

This study is designed to explore the patient's point of view on success with penile prosthesis. Detailed questionnaires were sent to 57 penile prosthesis recipients, 38 of whom responded. Overall, 89 per cent claimed improved sexual satisfaction, and 76 per cent noted improved self-image with their prostheses. Seventy-six per cent claimed their partners approved of the prosthetic device. Prost...

Although infrequent, infections represent the dreadful complication of penile prosthesis implantation. The incidence substantially decreases after a few infection-free postoperative months. We report herein a case of a very late penile prosthesis infection from a fistualizing scrotal abscess in a 67-year-old man. The patient presented with a one-month history of persistent penile-base discharge...

INTRODUCTION Implantation of an aortic-bifemoral prosthesis is characterised by a high (> 5%) rate of perioperative cardiovascular events. The main aim of the study is to demonstrate the usefulness of the determination of NT-proBNP concentration as a method of risk stratification of left ventricular dysfunction in patients subjected to surgery for aortic-bifemoral prosthesis implantation. MAT...

OBJECTIVE Trans-apical aortic valve implantation (TA-AVI) using the Edwards SAPIEN™ prosthesis has evolved to a routine procedure for selected high-risk elderly patients. In rare cases, misplacement of the SAPIEN™ valve (too low a position), dysfunction of the leaflets or perforation of the interventricular septum (ventricular septal defect, VSD) occurs and requires immediate implantation of a ...

INTRODUCTION Penile prostheses are subject to a continuous development and have gained better mechanical reliability and safety during the last decades. In this study, we aimed to investigate the outcomes and satisfaction rates of inflatable penile prosthesis (IPP) and semirigid penile prosthesis (SPP) implantation. MATERIALS AND METHODS From August 2001 to June 2012, 257 men with erectile dy...

OBJECTIVE This paper demonstrates the initial and pioneering experience implant of the Inovare prosthesis implant through transfemoral or iliac artery route. METHODS Six patients underwent transcatheter aortic valve implantation. The access was femoral or iliac through which the delivery device, a latex balloon catheter with the crimped prosthesis, was inserted. Through the femoral introducer...
