After birth, constriction of the full-term ductus arteriosus induces oxygen, glucose and ATP depletion, cell death, and anatomic remodeling of the ductus wall. The immature ductus frequently fails to develop the same degree of constriction or anatomic remodeling after birth. In addition, the immature ductus loses its ability to respond to vasoconstrictive agents, like oxygen or indomethacin, wi...

Colonic diverticular bleeding is the most common cause of lower gastrointestinal bleeding in adults [1,2]. Bleeding can occur from an injured branch of the submucosal plexus vessels at the neck or along the dome of the diverticulum [3]. While the majority (approximately 80%) of bleeding is self-limited, some patients can develop massive bleeding–perhaps because the submucosal plexus is derived ...

A right aortic arch is an anatomic variant only occurring in approximately 0.1% of the population. A mirror-image right artic arch without congenital cardiac anomaly is fairly uncommon. We report on a rare case of dysphagia due to isolated aortic diverticulum in a mirror-image right aortic arch. A 72-year-old man presented with dysphagia which was due to posterior compression of the esophagus b...

Background: Female urethral diverticulum is a condition which is often overlooked and frequently misdiagnosed. It is hoped that as a result of greater awareness of female urethral diverticulum more timely diagnosis of the condition would be made which would result in early appropriate treatment. Objective: The objective of this review is to summarize the presentation, investigation and manageme...

OBJECTIVE: To show various CT aspects of complicated Meckel's diverticulum in adult patients to facilitate the preoperative diagnosis of this rare pathology in emergency settings. METHODS: A computer search of medical records over a 15 year period identified 23 adult patients who underwent surgery for acute abdomen generated by a complicated Meckel's diverticulum. CT images available for revie...

Meckel's diverticulum may sometimes present as an intraluminal polypoid mass causing small bowel obstruction; however, gastrointestinal bleeding due to Meckel's diverticulum with a polypoid lesion is rare. A 14-year-old girl presented with tarry stool and syncope in our hospital. Laboratory examination showed iron-deficiency anemia with a low hemoglobin level of 5.8 g/dl. The bleeding site was ...

RATIONALE Small intestinal diverticulum with bleeding is an important reason for obscure gastrointestinal bleeding (OGB) , in addition to tumor and vascular diseases. Small intestinal diverticulum with bleeding is difficult to detect by barium meal and angiographic methods and has been regarded as an important cause of obscure gastrointestinal tract bleeding in adolescents. Because of its compl...

IntrOductIOn Diverticulum of the gall bladder is an important but distinct anatomical entity with significant clinical implications. Congenital diverticulum of the gall bladder is one of the rarest of all anomalies, corroborated by its very low incidence and infrequent reports and references in the literature [1]. Diverticulum can be of congenital or acquired variety. The congenital type contai...

Meckel's diverticulum is a rare condition with an incidence of 1-3% in general population. It is usually asymptomatic and is incidentally detected during laparotomy/laparoscopy. Enterolith formation within Meckel's diverticulum is even rarer. Herein, we present the diagnosis and management of a 50-year old patient with Meckel's diverticulum enterolith and discuss this rare condition based on th...

The ductus venosus regulates the distribution of oxygen and placental nutrients by restricting the centralization of blood flow in fetal circulation. The ductus venosus is a small vein transmitting oxygen-rich blood from the umbilical vein to the fetal heart.. Increasing numbers of case reports are being published about ductus venosus agenesis with cardiac structural abnormalities, other malfor...
