A diverticulum of the right atrium was found on the floor of the coronary sinus in a neonate. The diverticulum was distinguished from a pericardial cyst by contrast echocardiography, and its relations with coronary sinus and coronary venous return were identified by coronary angiography. Because the diverticulum compressed the left ventricular inferior wall and prevented its growth, it was exci...

Zenker’s diverticulum is a pouch protruding posteriorly above the upper esophageal sphincter (1). A small diverticulum may be asymptomatic, while a large one may produce dysphagia, food regurgitation, weight loss, and gastroesophageal reflux symptoms. Pneumonia has been reported as a complication in 12% of cases (2). I present the case of an elderly man whose recurrent complications of a Zenker...

Most of the intussusceptions in infants are idiopathic in nature. The incidence of intussusception decreases as the age advances. On the contrary, the frequency of lead point (secondary cause) increases with age. Meckel’s diverticulum is the commonest anomaly of small bowel. There is 5% incidence of complications in patients having Meckel’s diverticulum. Inverted Meckel’s diverticulum, as a lea...

A Meckel's diverticulum is a remnant of the vitelline duct, which leads to the formation of a true diverticulum containing all layers of the small intestine. The diverticulum can contain ectopic gastric, duodenal or pancreatic tissue and is the most common congenital anomaly of the gastrointestinal tract with estimates of prevalence ranging from 0.3% to 3%. The condition is usually clinically s...

In this retrospective study, 510 infants and children with patent ductus arteriosus (PDA) who underwent surgery at the Shahid Rajai Heart Hospital in Tehran were evaluated to determine the rate of surgical complications, morbidity and mortality. 30 patients (6%) developed minor to major complications postoperatively. Four patients who had undergone PDA ligation without division required reo...

Contractile responses of rings of ductus arteriosus from fetal and neonatal guinea pigs were studied in buffered Krebs-Henseleit solutions of various oxygen tensions. Oxygen-induced contraction of ductus arteriosus increased with gestational age, peaking at term and attenuating within 24 h after birth. Contractions of ductus in response to potassium were not different in term and preterm fetuse...

Regulation of ductus arteriosus (DA) tension depends on a balance between oxygen-induced constriction and PG and nitric oxide (NO)-mediated relaxation. After birth, increasing Pa(O(2)) produces DA constriction. However, as the full-term ductus constricts, it develops severe tissue hypoxia in its inner vessel wall (oxygen concentration <0.2%). We used isolated rings of fetal lamb DA to determine...

INTRODUCTION Meckel's diverticulum is the commonest congenital abnormality of the gastrointestinal tract. Most of them are asymptomatic but can rarely present with forms of complications such as bleeding, obstruction, diverticulitis, intussusception and neoplasm. Patients with a perforation of Meckel's diverticulum by a foreign body are rare and may present with right iliac fossa pain, which mi...

INTRODUCTION A temporary protective loop ileostomy is a routine procedure to protect the anastomosis in patients who undergo low anterior resection for rectal cancer. The aim of this case report is to present a rare complication caused by Meckel's diverticulum. CASE PRESENTATION We describe a case of a 71-year-old white man with dysfunctional ileostomy after low anterior resection for rectal ...

PURPOSE We present the management of 17 cases of urethral diverticulum in our department. We describe the various clinical presentations of urethral diverticulum, which may mimic other pelvic floor disorders and result in diagnostic delay. MATERIALS AND METHODS We reviewed 17 cases of urethral diverticulum presented to the urogynaecology department between January 2006 and February 2011 retro...
