하지 심부정맥혈전증에서 양측 하지 MDCT Direct Venography의 유용성

Usefulness of MDCT Direct Venography of both lower extremity in Deep Vein Thrombosis: Using Bypass Cannula

Purpose This study is to describe the method of CT examination for deep veins of both lower extremities simultaneously and to evaluate the usefulness of MDCT direct venography. Materials and Methods From september 2003 to october 2005, 32 patients were retrospectively identified at our hospital, as having deep vein thrombosis in lower extremities by MDCT direct venography with bypass cannula made by authors. Results We could scan both extremities simultaneously and the long segment of lower extremities with MDCT direct venography with bypass cannula at one time. Axial images, maximum intensity projection images and volume rendering images could be reconstructed easily, and venographies of extremities, pevis, and inferior vena cava be obtained. Conclusion MDCT direct venography with bypass cannula have the usefulness for examing the deep veins of both lower extremities simultaneously and the merits for comparing and accurate diagnosis of deep vein thrombosis using volume rendering techniques and maximal intensity projection techniques.
