Objective: Cardiac morbidity in aortic root replacement often occurs through myocardial ischaemia. We analyzed a 10 year experience of all root replacement operations by one surgeon to determine the incidence of coronary complications and risk factors for early mortality. Methods: The study included 140 aortic root replacement patients (aged from 2 to 77 years; median 53 years) operated between...

The current study evaluates histopathologic changes in the temporal bones of 4 human subjects who underwent revision cochlear implantation. Specimens were removed at autopsy, fixed and prepared for histological study by standard techniques. Specimens were serially sectioned, reconstructed by two-dimensional methods, and the tracks of the initial and revision cochlear-implant electrodes identifi...

BACKGROUND The lifesaving treatment endured by cancer patients leads, in many women, to early menopause and subsequent infertility. In clinical situations for which chemotherapy needs to be started, ovarian tissue cryopreservation looks to be a promising option to restore fertility. In 1997, biopsy samples of ovarian cortex were taken from a woman with stage IV Hodgkin's lymphoma and cryopreser...

Purpose: To present our experience of laparoscopic ureteral reimplantation using intracorporeal ureteral tapering for management of distal ureteral stricture. Materials and Methods: Between April 2005 and October 2008, six patients, including 3 children and 3 adults, underwent laparoscopic modified Lich-Gregoir type extravesical ureteral reimplantation for distal ureteral stricture. Significant...

OBJECTIVE Aortic insufficiency (AI) associated with ascending aneurysm can be corrected by valve-sparing aortic root reconstruction ('David' reimplantation, 'Yacoub' remodeling). Intraoperative endoscopic evaluation in the aortic root may help to clarify the procedure and to access competence of the preserved valve. METHODS Following cross-clamping of the ascending aorta, an endoscopy was ins...

Objective: To compare two different techniques for ureteric reimplantation management of Vesicoureteric reflux in children. Study Design: Comparative study. Setting: Department Pediatric surgery at D. G Khan Medical College Dera Ghazi Khan. Period: January 2010 to April 2021. Material & Methods: Seventy four patients with vesicoureteric were included. Extravesical technique was performed 35...

We recently proposed a new surgical approach to treat ventral root avulsion, resulting in motoneuron protection. The present work combined such a surgical approach with bone marrow mononuclear cells (MC) therapy. Therefore, MC were added to the site of reimplantation. Female Lewis rats (seven weeks old) were subjected to unilateral ventral root avulsion (VRA) at L4, L5 and L6 levels and divided...

The efforts of Drs. Patrick C. Steptoe and Robert G. Edwards in England culminated in the birth of Louise Brown on July 25, 1978, as a result of in vitro fertilization and reimplantation of the human embryo into the mother's womb.' The same investigators later reported the birth of a boy by this technique. 2 Since then, several hundred babies have been born by this methodology. More recently, f...

INTRODUCTION AND OBJECTIVES The cochlear implant is a surgical procedure that has increased substantially, because the paediatric population is diagnosed and implanted early and because there are increased potential indications. This device has the inherent risk of failure in performance, as dies any active medical device, which is the most common cause of implant removal. Our goal was to under...

OBJECTIVES Anomalous aortic origin of a coronary artery is uncommon but potentially clinically significant. Manifestations vary from asymptomatic patients to those who present with angina pectoris, myocardial infarction, heart failure, syncope, arrhythmias, and sudden death. We describe our experience with surgical reimplantation and results at midterm follow-up. METHODS Between February 2003...
