Rib cage mechanics after median sternotomy.
A substantial reduction in lung volumes occurs after sternotomy, but the mechanism or mechanisms are unclear. Measurements were made of lung volumes and of chest wall motion with four pairs of magnetometers (two pairs for anteroposterior rib cage, one for lateral rib cage, and one for anteroposterior abdominal dimensions) in 16 men before and one week and three months after coronary artery graf...
متن کاملEvaluation of Thymic Changes after Median Sternotomy in Children
In patients who undergo median sternotomy to treat congenital heart diseases, a thymectomy is performed to yield better access to the cardiac system. In this study we have used MRI to evaluate the changes in size, shape and location of the thymus after midsternatomy. This case-control study was performed during 2011-2012 in Shiraz, Iran. Eligible participants between 5-17 years of age were divi...
متن کاملRepair of incisional hernia after median sternotomy.
About 19 000 cardiac surgical procedures are carried out annually in the United Kingdom, 4000 being for congenital defects (UK Cardiac Surgical Register: Society of Thoracic and Cardiovacular Surgeons of Great Britain and Ireland, 1983). Most of these procedures use the median sternotomy incision for access to the heart and great vessels. Epigastric incisional hernias may occur as a complicatio...
متن کاملBrachial plexus injury after median sternotomy.
Serious brachial plexus injury after median sternotomy is uncommon. However, affected patients experience considerable morbidity and their return to regular employment is often delayed. The pathogenesis of the injury is multifactorial. Wide sternal retraction is the major etiologic factor. Management is primarily conservative and should be guided by a team experienced in upper limb and hand sur...
متن کاملRib cage mechanics during quiet breathing and exercise in humans.
During exercise, large pleural, abdominal, and transdiaphragmatic pressure swings might produce substantial rib cage (RC) distortions. We used a three-compartment chest wall model (J. Appl. Physiol. 72: 1338-1347, 1992) to measure distortions of lung- and diaphragm-apposed RC compartments (RCp and RCa) along with pleural and abdominal pressures in five normal men. RCp and RCa volumes were calcu...
