RMS, rhabdomyosar-Abstract Background: The surgical management of paediatric bladder/prostate rhabdomyosarcoma (B/P RMS) continues to develop, with the goal of maximising organ preservation while achieving successful cancer control. The timing of radio-therapy and surgical excision to improve event-free survival (EFS) and overall sur-vival (OS) remains controversial. Methods: Previous reports in English on B/P RMS over the past 15 years were identified and reviewed, focusing on studies comparing the effects of radiotherapy and surgery for local control, the effect of local control on OS, and improved means of diagnosing viable tumour after chemotherapy. Results: The concept of lowering the ‘cost of cure ’ drives current protocols. Blad-otherapy, with a f urine, and add-tudies suggesting therapy did not determinants o

Evaluation of Coronary Artery Bypass by CT Coronary Angiography

Coronary computed tomography angiography (CCTA) is an accurate method for graft imaging and assessment than invasive coronary angiography (ICA). CTA has excellent sensitivity and specificity. The chapter describes the role of CTA in evaluation of coronary bypass graft. It covers the appropriate indications for performing CTA after bypass operation, patient preparation, as well as protocol and technique of CTA. The chapter describes the post-examination processing of the images and how to interpret CTA images for detection of graft patency or dysfunction as occlusion, partial thrombosis, poor blood flow, and stealing flow from native artery. According to the American College of Cardiology, the American College of Radiology, and the North American Society for Cardiovascular Imaging, graft patency assessment with CTA is an appropriate approach in symptomatic patients at risk for graft stenosis/occlusion. Cardiac CT can be used to assess the patency of coronary artery bypass graft (CABG) with high diagnostic accuracy compared with ICA and even with a better performance compared to the assessment of native coronaries
