Abstract:
Objective:To explore the clinical value of color Doppler ultrasound and multi-slice spiral computed tomography (MSCT) in the diagnosis of pulmonary thromboembolism (PTE)- deep vein thrombosis (DVT).Methods: A retrospectively study was adopted to analyze 30 patients with suspected PTE-DVT. The patients with suspected PTE were applied by using MSCT and series three-dimensional reconstructions, such as volume reconstruction (VR), multi planar reconstruction (MPR), maximum intensity projection (MIP) and axial image reconstruction, while the patients with suspected DVT were scanned by using color Doppler flow imaging (CDFI). The shape, size and location of embolus in blood vessel were observed, and the situations of pulmonary artery embolism and the phenomenon of deep vein embolism detected by the two methods were compared and analyzed.Results: In 30 cases, there were 15 cases were diagnosed as positive patients, and in the 15 cases, the patients with DVT were 66.7% (10/15), while the patients with PTE were 86.7% (13/15), and the patients with PTE-DVT were 8 cases (53.3%, 8/15). By using MSCT, there were 10 patients with thromboembolism in pulmonary artery were found, and there were 50 pulmonary arteries with thromboembolism were diagnosed. On the other hand, by using color Doppler ultrasound, there were 12 patients with embolism and fluctuation disappearing of vein wall in deep vein were found, and there were 16 deep veins with thromboembolism were diagnosed.Conclusion: Color Doppler ultrasound should combine with MSCT and they should learn each other so as to achieve the diagnosis of PTE-DVT in convenient, fast, simple, safety and accuracy. This combination of them can provide important reference for clinical therapy of PTE-DVT.
