ABSTRACT Background: Congenital malformations of lung, such as congenital lobar emphysema, cystic adenomatoid malformation, bronchial cyst, pulmonary sequestration are rare occurrence. However, our hospital being in a rural area attracts large number patients with complex malformations. Method: This retrospective analysis is done to evaluate diagnostic accuracy, safety and efficacy outcomes ope...

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...

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...
