Post-Oberlin procedure cortical neuroplasticity in traumatic injury of the upper brachial plexus

Constrictive pericarditis is characterized by thick pericardial fibrosis and frequent calcification that progressively impairs diastolic filling of the heart, with associated symptoms of heart failure (1) . Annular constrictive pericarditis is extremely rare, and few similar cases have been reported (1) . Previous pericardiectomy, congenital heart disease, and complications of tuberculosis may be the leading causes of this condition. Depending on the location of the pericardial constriction, the clinical presentation of localized constriction may differ, including obstruction of the right ventricular outflow tract, coronary obstruction, and pulmonary stenosis (1)(2)(3) . The imaging evaluation of cardiovascular calcifications has been the subject of a series of recent publications in the Brazilian radiology literature (4)(5)(6)(7) . Multislice computed tomography may be an important tool for the precise identification of annular constrictive pericarditis (8) .
