DiGeorge’s syndrome is a 22q11.2 deletion leading to abnormal embryogenesis of pharyngeal arches and it manifesting in variety clinical signs symptoms. The spectrum anomalies varies from minor facial dysmorphism cleft palate broad cardiovascular anomalies, thymic disfunction immune deficiencies, hypocalcemia due tohypoparathyroidism,growth developmental delay speech disturbances. Cardiovascular...

background and aim: horseshoe placenta is a variant of ring-shaped placenta. ring-shaped placenta is a rare anomaly seen in fewer than 1 in 6000 deliveries, which could be seen as horseshoe shape due to atrophy in a portion of the ring. this report refers to a possible relationship between the horseshoe shape placenta and preterm labor; although it has not been yet validated in the literature. ...

CONTEXT Annular pancreas is an uncommon and rarely reported congenital anomaly which consists of a ring of pancreatic tissue encircling the duodenum. Despite the congenital nature of the disease, clinical manifestations may ensue at any age. CASE REPORT We herein report the case of a 72-year-old female with acute pancreatitis associated with duodenal obstruction. On radiologic examination, an...

We explore the connection between anti-deSitter supergravity and gauge theory, in the context of bound states of many D1 and D5 branes. The near-horizon AdS3 supergravity describes the identity sector of the conformal field theory produced by the brane dynamics. A variant of anomaly inflow (for the 2d conformal anomaly) is involved. Dynamical matter fields on AdS3 couple to the chiral ring and ...

Based on chiral ring relations and anomalies, as described by Cachazo, Douglas, Seiberg and Witten, we argue that the holomorphic effective action in N=2 Yang-Mills theory can be understood as an integrated U(1) anomaly from a purely field theory point of view. In particular, we show that the periods of the Riemann surface arising from the generalized Konishi anomaly can be given a physical int...

Introduction Although the circulatory system cannot properly be considered except as a whole, there is such an abundance of pathological conditions to which it is subject, in whole or in part, that limitations of space alone demand that it be divided into parts and that only a part be considered here. This paper will therefore be confined to the peripheral vascular system, which is arbitrarily ...

Pediatric vascular malformations of the central nervous system differ from those seen in adults. Their classification may be based on symptoms, pathomechanics, patient's age, morphologic features, or presumed etiology. This review describes the different classification schemes and the endovascular management options of these rare and challenging diseases. The proposed etiologic classification o...

Abstract Background Aortic arch and vertebral artery anomalies are vascular variations that occur as a result of embryological developmental defects. Bicarotid trunk anomaly is rare aortic refers to common single origin carotid arteries. VA mostly unilateral the most LVA originating from arch. Abnormal RVA RCCA anomaly. In this case, we presented ARSA bicarotid with abnormal Case presentation A...

Vein of Galen aneurysm malformation (VGAM) is a rare congenital vascular anomaly. Although the cause of VGAM remains to be elucidated, the current hypothesis is persistence of the embryonic vascular supply, which leads to progressive enlargement and formation of the aneurysmal component of a typical VGAM. Here, we present a 36-year-old woman at 23 weeks' gestation (gravida 3, para 2) who was ev...

BACKGROUND Class 3 urogenital malformations are a rarely encountered in the clinical setting. The association with complex vascular malformations represent a challenge in diagnosis and intraoperative management with an enhanced degree of the complexity. CASE PRESENTATION Young female presented to the emergency department with pain in the left lower quadrant and unspecific abdominal symptoms t...
