OBJECTIVE To estimate the incidence of major and minor congenital malformations among liveborn infants at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Estimation of risk factors were also evaluated. METHODS Between March 2004 and May 2005, a total of 5356 babies born at King Abdulaziz University Hospital, were enrolled in this study for malformations. Details of cases were record...

Pulmonary sequestration (PMS) is a rare bronchopulmonary malformation. It has an incidence of between 0.15% to 1.7%. Likewise, cystic adenomatoid malformation (CCAM) is another relatively rare category of a bronchopulmonary malformation with a reported incidence of between 1 in 25,000 to 1 in 35,000. Moreover, a bronchopulmonary malformation with features allied to both of these forms is consid...

The authors studied the plain radiographs and medical records of 5000 military recruits, mean age 19.1 years (range: 18 to 22), screened in a Turkish Military Hospital in the period November 2008-October 2009. They focused on the incidence of congenital lumbosacral malformations, such as spina bifida occulta and transitional vertebra, trying to find a correlation with subsequent low back compla...

OBJECTIVE The aim of this study was to determine the posterior cranial fossa volume, cerebellar volume, and herniated tonsillar volume in patients with chiari type I malformation and control subjects using stereological methods. MATERIAL AND METHODS These volumes were estimated retrospectively using the Cavalieri principle as a point-counting technique. We used magnetic resonance images taken...

Dandy-Walker malformation is a rare congenital malformation and involves the cerebellum and fourth ventricle. The condition is characterized by agenesis or hypoplasia of the cerebellar vermis, cystic dilatation of the fourth ventricle, and enlargement of the posterior fossa. A large number of concomitant problems may be present, but the syndrome exists whenever these three features are found. A...

Gestational diabetes mellitus (GDM) is one of the leading causes of fetal malformations. However, few models have been developed to study the underlying mechanisms of GDM-induced fetal eye malformation. In this study, a high concentration of glucose (0.2 mmol per egg) was injected into the air sac of chick embryos on embryo development day (EDD) 1 to develop a hyperglycemia model. Results showe...

BACKGROUND Renal arteriovenous malformation is an aberrant vascular connection between the renal artery and vein. Acquired renal arteriovenous malformation (arteriovenous fistulae) accounts for approximately 70% of renal arteriovenous abnormalities. Congenital renal arteriovenous malformation, relatively rare, can result in significant hematuria which may require arterial embolization or nephre...

This study is to investigate hematuria in pregnant patients caused by renal arteriovenous malformation and to evaluate the efficacy of superselective renal angiography and embolization used for treatment of renal arteriovenous malformation. Two cases of hematuria in pregnant patients caused by renal arteriovenous malformation were enrolled. Case 1 was a 28-year-old woman with repeatedly intermi...

According to a new international classification of vascular lesions, venous vascular malformation has become the most common type of congenital vascular malformation. A characteristic of this disease is its life‐long progressive development, which is the main cause of harm to health and is different from hemangioma. Severe hemangioma with thrombocytopenia (Kasabach–Merritt syndrome)[1] is often...

Venous malformations arising from the peripheral nerve are a rare type of vascular malformation. We present the first case of an intraneural venous malformation of the median nerve to be reported in a child and review the previous two cases of median nerve compression due to a venous malformation that have been reported. These cases presented with painless masses in the volar aspect of the wris...
