Methods: Eighteen patients with central lungcancer underwent MSCT with real time helical thin-slice CT scanning. Three-dimensional bronchialartery reconstruction was done at the console work-station. The space anatomical characters ofbronchial artery were observed through different rotations. Results: For 6 cases, thethree-dimensional images of bronchial artery (33.33%) could exactly show the origins, the routes(lung inner segment and mediatism segment) and the diameters of bronchial arteries. Vision rate ofbronchial arteries was the highest in pulmonary artery stricture and truncation groups, and thevessels' diameter became larger apparently. These characters demonstrated blood supply of this kindof central lung cancer come from bronchial artery. Volume rendering images were the best ones amongthree-dimensional images. Conclusion: Three-dimensional imaging with MSCT in bronchial artery canreveal the anatomical characters of bronchial artery and provide theoretical evidence on bloodsupply and intervention therapy of central lung cancer.展开更多

Methods We retrospectively analyzed 447 patients with multivessel disease who experienced a ST-segment elevation myocardial infarction （STEMI） within 12 h before undergoing PCI between July 26, 2008 and Septem- ber 25, 201 l. After completion of PCI in the infarct artery, 201 patients still in the hospital agreed to undergo PCI in non-infarct arteries with more than 70% stenosis for a ＂one-week＂ staged multivessel PCI. A total of 246 patients only received intervention for the culprit vessel. Follow-up ended on September 9, 2014. This study examined the differences in deaths from any cause （i.e., cardiac and noncardiac） and MACE between the two treatment groups. Results Compared to a culprit-only PCI treatment approach, the ＂one-week＂ staged multivessel PCI was strongly associated with greater benefits for 55-month all cause death [41 （16.7%） vs. 13 （6.5%）, P = 0.004] and MACE [82 （33.3%） vs. 40 （19.9%）, P = 0.002] rates. In addition, there were significant differences in the number of myocardial infarctions [43 （17.5%） vs. 20 （10.0%）, P = 0.023], coronary-artery bypass grafting [CABG; 20 （8.1%） vs. 6 （3.0%）, P = 0.021], and PCI [31 （12.6%） vs. 12 （6.0%）, P - 0.018]. Patients undergoing culprit-only PCI compared to ＂one-week＂ PCI had the same number of stent thrombosis events [7 （2.8%） vs. 3 （1.5%）, P - 0.522]. Conclusions Compared to a culprit-only PCI treatment approach, ＂one-week＂ staged multi-vessel PCI was a safe and effective selection for STEMI and multi-vessel PCL展开更多
