Thermal damage of internal thoracic artery and ultra high radiofrequency
نویسندگان
چکیده
Background The gold standard in left anterior descending branch coronary artery surgery is performing an internal thoracic artery (ITA) bypass. Skeletonization techniques of harvesting have been suggested for maximizing the utility of ITA. It still remains questionable what is the best method for ITA harvesting in a skeletonized fashion according to structural integrity of artery, as a risk factor of early and late graft failure. The purpose of this study was to determine the impact of the ultra-high radiofrequency energy (2.0 – 4.0 MHz) used for ITA harvesting on arterial structural integrity, in particular on the endothelial layer.

In the electromagnetic spectrum, structural damage to living tissues per unit of absorbed energy tends to increase with the decrease of a wavelength which is evident not only for ultraviolet and ionizing radiation but also for the infrared and visible light. By causing thermal damage after absorbing energies that would be harmless for radiofrequency electromagnetic fields (EMF), tissues are eve...

متن کاملComparison of the right internal thoracic artery and radial artery as a second arterial conduit in ‘Y’ composite fashion in patients undergoing coronary artery bypass grafting using total arterial revascularization
Introduction: The use of two arterial conduits for CABG is rapidly increasing. The second arterial conduit to LITA is usually RITA or radial artery. We sought to compare outcomes when either RITA or radial artery is exclusively used as a Y composite graft to LITA for total arterial revascularization. Material and methods: We retrospectively analyzed 231 ...

Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
متن کاملI-46: Radiofrequency Ablation of Uterine Fibroids
Uterine fibroids are benign solid tumors that are present in the majority of women. While often asymptomatic, fibroids can result in abnormal uterine bleeding, pelvic pressure, pain, subfertility, dyspareunia and other symptoms. Submucous and intramural fibroids are most associated with heavy menstrual bleeding; subserosal fibroids are more often innocuous unless sufficiently large so as to con...
