PURPOSE: To evaluate the feasibility of using fragmented microcoils as embolization material. MATERIAL AND METHODS: Fragmented microcoil particles were produced from a coil of 0.42-mm platinum guide wire. The diameter of the particles was 420 mu and the length was 450-800 mu. To prevent the catheters from being obstructed by the particles, a core shaft wire was passed through the channels of the particles and a hollow plunger was used to release particles from the catheter. Forty particles were introduced into 4 kidneys in 4 adult dogs following transfemoral catheterization and systemic heparinization. Renal arteriography was performed immediately, and at 60 min, and at 3 weeks after embolization. RESULTS: All particles were successfully introduced into the periphery of the kidneys, and caused occlusion within 3 weeks of embolization. CONCLUSION: Fragmented platinum microcoil particles can be used as embolization material to avoid catheter obstruction. |
