Intussusception is well-recognised in young children; however this condition is very rare in newborns [1]. Neonatal intussusception is usually caused by several conditions including Meckel’s diverticulum, intestinal polyps and intestinal duplication [1]. Meckel’s diverticulum can present at any age group; however rarely, a symptomatic Meckel’s diverticulum may present in neonates [2]. We report...

BACKGROUND Patent ductus arteriosus is a risk factor for the development of necrotizing enterocolitis. The use of indomethacin to treat patent ductus arteriosus in preterm infants may either decrease the incidence of necrotizing enterocolitis by stabilizing or closing the ductus arteriosus or increase its incidence by a direct constricting effect on mesenteric blood vessels. The authors sought ...

Anatomic remodeling and permanent closure of the newborn ductus arteriosus appears to require the development of intense hypoxia within the constricted vessel wall. Hypoxic ductus smooth muscle cells express vascular endothelial cell growth factor (VEGF). We studied premature baboons and sheep to determine the effects of VEGF inhibition (in baboons) and VEGF stimulation (in sheep) on ductus rem...

Nonselective cyclooxygenase (COX) inhibitors are potent tocolytic agents; however, they also have adverse fetal effects such as constriction of the fetal ductus arteriosus. Recently, selective COX-2 inhibitors have been used in the management of preterm labor in the hope of avoiding fetal complications. However, both COX-1 and -2 are expressed by cells of the ductus arteriosus. We used fetal la...

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 reopera...

We successfully closed the isolated patent ductus arteriosus in 58 of 61 consecutive patients using the transfemoral-catheter method originally introduced by Porstmann in 1968. To perform this technique more safely and reliably, some instrumental and technical improvements were made. The indications for this method have been expanded to include the cylindrical or window-type ductus as well as t...

A 57-year-old woman presented with dysphagia and postprandial epigastric fullness for about two years. Esophagogastroduodenoscopy (EGD) showed a esophageal diverticulum at the lower portion of the esophagus, and barium swallow esophagography showed a focal outpouching space (measured about 5cm in size) at the distal third of the esophagus near the esophagogastric junction (●" Fig.1). The patien...

The patient was a 60-year-old man with encephalopathy without liver cirrhosis. CT angiography revealed a patent ductus venosus between the anterior segmental branch of the portal vein and the middle hepatic vein. Coils were framed in the patent ductus venosus and then used to fill in the frame. After treatment, transarterial portography showed that the shunt flow of the ductus venosus had decre...

tc-99m pertechnetate scintigraphy is the modality of choice for diagnosis of meckel's diverticulum. interpretation of meckel's scan identifies a focal area of radiopharmaceutical uptake in the anterior abdomen similar to normal gastric mucosa. the activity must be of the same pattern and intensity as gastric uptake. we present a 13-year-old patient with gastrointestinal bleeding and anemia. tc-...
