v Contents Preface ix Introduction to Vascular Anomalies by Lauren A. Kilpatrick, MD xi Acknowledgments xvi Contributors xvii

Objective: To describe the presentation and management of vascular anomalies of the face in the Plastic and Reconstructive Surgery Unit, Hayatabad Medical Complex, Peshawar. Meterial and Methods: This descriptive study was carried out in the Department of Plastic & Reconstructive Surgery, Hayatabad Medical Complex (HMC), Peshawar during a period from March 2009 to December 2012. All patients wi...

THORACIC ARTERIALI ANOMALIES were formerly regarded as having little significance except when they produced tracheal or esophageal obstruction. As thoracic surgical procedures become more prevalent in the smaller or community hospitals, the case concentration will become less, and many of these anomalies may go unrecognized. Recognition of the many types of vascular disarrangement thus assumes ...

Background/Introduction Congenital anomalies of the aortic arch gather a wide spectrum of malformations concerning the aortic arch or some of its branches and the pulmonary artery. These malformations are rare (1 in 1000 live births) and sometimes responsible of complete (vascular ring) or partial (vascular sling) encirclement of the oesophagus, trachea or bronchi. In cases of symptomatic airwa...

Vascular anomalies and variants are common in patients undergoing imaging studies, and patients with these anomalies are generally asymptomatic. Remnants of fetal carotid-basilar circulation are rarely identified. We report a rare case of persistent type 2 bilateral proatlantal arteries, in which the patient presented with dizziness.

The common vascular anomalies of cerebral aneurysm and arteriovenous malformation may exist independently, or together as part of a closely related hemodynamic pairing. Resection or embolization of an AVM may be followed by a decrease in local blood flow, and lead to regression of a suitably situated proximal aneurysm. However, aneurysms located outside the angioarchitecture of the AVM, which r...

Congenital anomalies of the great thoracic vessels have been reported in 20% of dogs and cats. In some cases, the vascular ring anomalies remain unrecognized throughout the lifetime of an animal. This report describes a case with an unusual vascular ring anomaly (VRA) that was detected during dissection on a cadaver of an approximately two-year-old male native mixed breed dog. No history of the...

BACKGROUND Diagnosis of extracardiac intrathoracic vascular anomalies is of clinical importance, but remains challenging. Traditional imaging modalities, such as radiography, echocardiography, and angiography, are inherently limited by the difficulties of a 2-dimensional approach to a 3-dimensional object. We postulated that accurate characterization of malformations of the aorta would benefit ...

A patient with karyotype 46,XY,der(4) was recognized by standard cytogenetic techniques, and presented with facial features, neurological impairment and pulmonary hypertension. Multiplex ligation-dependent probe amplification (MLPA) demonstrated duplication of the subtelomeric region of chromosome 16p and deletion of the subtelomeric region of chromosome 4q, suggesting a translocation between 4...

There is frequently lack of understanding and apprehension among dental practitioners treating patients with vascular lesions of the oral and maxillofacial region. Arteriovenous malformations are rare lesions which can easily be misdiagnosed yet produce the very dramatic clinical presentation of severe life threatening oral bleeding. Much of this apprehension likely stems from a lack of underst...
