ABSTRACT
Objective To evaluate the three-dimensional reconstruction and significance of arterial cast on chronic venous insufficiency of low extremity. Methods A set of specimen on chronic venous insufficiency of left lower extremity amputation residues was infused with epoxy resin-lead oxide through the femoral artery,and then casted. The CT data of the cast specimen was used to reconstruct 3D modal of ar-tery on chronic venous insufficiency of left lower extremity,using the volume rendering(VR) and maximum intensity projection(MIP). Re-sults The cast specimen and 3D reconstruction of chronic venous insufficiency of left lower extremity amputation residues could clearly dis-play distribution and run of lower extremity arteries,blood supply of lesion and local region embolism of small artery ( arteriole) . Conclusion The 3D modal of artery on chronic venous insufficiency of left lower extremity should provide morphological basis of exact etiology and perfect pathogenesis,also has a certain guiding significance of clinical diagnosis and treatment.
