ObjectiveTo explore the application of cardiac enhanced MRI in acute myocardial infarction with normal result of coronary angiography. MethodsOn October 18, 2013, a male patient underwent coronary angiography under the local anesthesia. Mild coronary stenosis both in left and right side were found in the surgery, but the results of dynamic cardiogram and myocardial markers were abnormal, which accorded with the clinical procedure of myocardial infarction. The patient underwent cardiac enhanced MRI at the 6th day and was finally diagnosed as acute myocardial infarction. We reviewed the database to find out the significance of cardiac enhanced MRI in diagnosis of acute myocardial infarction. ResultsAlthough coronary angiography was the gold standard for the diagnosis of coronary diseases, it had limitations in the diagnosis of coronary eccentric stenosis, branch vascular stenosis and coronary spasm. Cardiac enhanced MRI had the advantages of accurate measurement of the attenuation of myocardium and exhibition of functional changes of ischemic myocardium. ConclusionCardiac enhanced MRI is important for the diagnosis of myocardial infarction with normal result of coronary angiography.
ObjectiveTo summarize the prevention method for pancreatic fistula following pancreaticoduodenec-tomy. MethodLiteratures related to the prevention methods for postoperative pancreatic fistula at home and abroad in recent years were retrieved and summarized. ResultsThe pancreatic fistula was a common complication following pancreaticoduodenectomy. It was mainly caused by preoperative continuous high jaundice, selection of intraoperative anastomosis, and early postoperative pancreatic juice secretion. Trypsinogen was activated by alkaline intestinal juice and then the nearby tissue was digested. Pancreatic juice flowed into abdominal cavity to digest the tissue, then caused serious complications or even death. Through the prevention of drugs, preoperative biliary drainage and intraoperative anastomosis, etc., the incidence of postoperative pancreatic fistula was slightly decreased. ConclusionThe prevention for postoperative pancreatic fistula is an integrated process, and it needs to be ran through the whole perioperative period.
