The information is helpful in diagnosis, pre-operative evaluation and post-operative follow-up of LPS.展开更多

Methods: Thin-section enhanced CT scanning (with an Toshiba Aquilion 16 scanner) was performed in 164 PLC patients, of whom 123 were confirmed by pathology and the remaining 41 were confirmed by typical radiological and clinical findings. Another 46 patients with normal thoracic CT presentations were served as control. Three-dimensional (3D) images of the BAs were processed at workstation (Vitrea 2, Vital Corp, USA). Spatial anatomical characters of the BAs were observed using volume rendering (VR) and muhiplanar reconstruction (MPR) or maximum intensity projection (MIP). Results: At least one bronchial artery was displayed clearly on VR in 152 (92. 7%) of the 164 PLC patients and 32 (69. 6%) of the 46 controls. There were 48. 92% of the right BAs originating from the descending aorta and 46. 24% from the right intercostal artery. 97. 53% of the left BAs originated from the descending aorta, and 94. 87% of the common trunk from the descending aorta. There were 10 distribution patterns of the BAs, with one on the right and one on the left predominating (48. 68%). More BA branches were found to reach far from the segmental bronchi or enter into the lesions in the PLC group than those in the control group (25. 8% vs 1. 7% ). and also the ipsilateral side of the PLC than the contralateral side (40% vs 8. 8%). The diameter and the total transaxial areas of the BAs on the ipsilateral side of the PLC lesions were significantly larger than those on the contralateral side or those of the control group (P<0. 05). Conclusion:The anatomic characters and pathologic changes can be depicted in vivo stereographically and clearly by CTA with volumetric 3D rendering. Dilation of the BAs and increase of total blood flow in patients with PLC can be evaluated quantitatively, which may be useful in the diagnosis and assessment of PLC, and have the potential to increase the-safety and effect of interventional therapy.展开更多

The etiology and integrated curative effect of severe hemoptysis due to pulmonary tuberculosis among 112 inpatients were analyzed. Materials and Methods: The cause was retrospectively analysed. The integrated management effect after the follow-up of mean three years in 112 cases with severe hemoptysis being resulted from pulmonary tuberculosis from June 2008 to July 2012 was described. Active pulmonary tuberculosis ranked the first cause of lower respiratory tract bleeding (32/112, 28.5%), followed by old pulmonary tuberculosis (28/112, 25.0%), tuberculous bronchiectasis (25/112, 22.3%), purified tuberculous cavity (12/112, 10.7%), fungal infection in old pulmonary tuberculosis cavity (9/112, 7.1%), or broncholithiasis (6/112, 5.4%). Almost all suffers with severe hemoptysis were treated by an integrated management, including psychology, anticoagulants, vasoconstrictor agents. Etiological treatment including anti-tuberculosis and anti-infection was simultaneously or subsequently involved. Sixty-four inpatients with severe hemoptysis being failed to be cured by medical treatment were then received selective bronchial artery embolization. Four patients were received surgical wedge resection, lobectomy or pneumonectomy. The total cure rate added up to 98.2% after mean three years’ follow-up. The mortality was 1.8%. Conclusions: Active pulmonary tuberculosis was still responsible for the severe hemoptysis in the southeast region of China. Severe hemoptysis of pulmonary tuberculosis was also resulted from stable tuberculosis, tuberculous bronchiectasis, tuberculosis cavity, fungal infection, or broncholithiasis. Better clinical therapeutic effect could be attained by early etiological diagnosis and comprehensive treatment strategy.展开更多
