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 studied 32 patients ≥ 90 years （93.0 ± 1.2 years） who underwent cardiac catheterisation in a tertiary specialist hospital （0.2% of 14,892 procedures during three years）. The results were compared to a patient cohort younger than 90 years of age. Results Baseline characteristics revealed a higher prevalence of diabetes （P 〈 0.001）, chronic obstructive pulmonary disease （P 〈 0.04）, previous myocardial infarction （P 〈 0.02）, and complex coronary anatomy （SYNTAX score 33 vs. 19） in nonagenarians. Patients 〈 90 years of age showed more hyperlipidemia （P 〈 0.01） and previous percutaneous coronary interventions （P 〈 0.015）. Nonagenarians underwent coronary angiography more often for acute coronary syndrome （ACS） （P 〈 0.003）, were presented more often in cardiogenic shock （P 〈 0.003）, and were transferred faster to coronary angiography in cases ofACS （P 〈 0.0001）. The observed in-hospital mortality rate （13% study group vs. 1% control group; P 〈 0.003） in nonagenarians was lower than the calculated rate of thrombolysis in myocardial infarction （TIMI） and global registry of acute cardiac events （GRACE） mortality and strongly influenced by the severity of clinical presentation and the presence of co-morbidities. Conclusion Despite the common scepticism that cardiac catheterisation exposes patients 〉 90 years to an unwarranted risk, our data demonstrate an acceptable incidence of complications and mortality in this group of patients.展开更多
