The Amplatzer Vascular Plug (AVP) including AVP 4 has excellent occlusion; however, and insufficient embolization or recanalization occurs at times. The study aimed to evaluate the feasibility and effectiveness of experimental test with vascular model and catheter placement by using the internal coil packing method to insert microcoils into the AVP 4. The insertion of a 1.7 F microcatheter through the Nitinol mesh of the AVP 4 was not possible. Only 0.010 inch electrolytic detachable microcoils could be inserted under catheter tips in contact with Nitinol mesh. The internal coil packing of the AVP 4 for continued perfusion or recanalization with required short-segment embolization may be accomplished by inserting 0.010 inch microcoils into the AVP 4.
