Objective To study the clinical value of 3 methods of bronchial artery embolization for the treatment of massive hemoptysis, and to observe healing effect and complication after different methods and embolic materials. Methods Selective bronchial artery embolization was performed in 93 patients with massive hemoptysis, among them 26 were embolized with simple gelfoam particles, 30 patients with sandwich bronchial artery embolization, and 37 patients with fourfold sandwich bronchial artery embolization. All patients were followed up for six to twenty-four months. Results The recent efficiency rates of three groups were as follows: simple gelfoam particles 92%(24/36), sandwich bronchial artery embolization 100%(30/30), fourfold sandwich bronchial artery embolization 100%(37/37). There was recrudescence in patients with treatment of simple gelfoam particles and sandwich bronchial artery embolization, but no recrudescence was found in patients treated with fourfold sandwich bronchial artery embolization. Conclusion Fourfold sandwich bronchial artery emblization is one of simple and highly effective methods with minimal trauma in treating massive hemoptysis.

Objective To discuss the application values of image reconstructive technique in 16-slice helical CT scanning. Methods 32 cervical spinal cord lesion images which have processed in MPR, MIP and VR were reviewed to discover the best image reconstructive form. Results By grading, reconstruction score of MPR, MIP and VR was 4.75, 1.75 and 4.5, MPR and VR in top. Conclusion 16-slice CT scanning with MPR and VR image reconstructive of cervical spinal cord can be satisfied the clinical demands.
