Coronary aorto-ostial stenosis analysed by multislice computed tomography: a new tool for percutaneous coronary intervention?
This study shows that CT associated with an angiogram allows a better identification of aorto-ostial plaques morphology and ideal stent position in aorto-ostial coronary stenosis before angioplasty.
Recent studies in esophagogastric cancer help clarify the role of radiation therapy in surgical management, as well as the role of chemotherapeutic and targeted agents.
