Objective: To evaluate the clinical utility of the coil in plug (CIP) method in internal iliac artery (IIA) embolization during endovascular aortic aneurysm repair (EVAR) compared to conventional coil embolization (CCE).
Material and Methods: From July to December 2018, 10 patients who underwent IIA embolization during EVAR were divided into CIP (n=5) and CCE (n=5) groups. In the CIP technique, the AVP-1 with a size more than 30%–50% of that of the embolized IIA diameter was used. The AVP-1 was deployed in the IIA. Before detachment of the AVP-1, a 2.2-F micro catheter was inserted through the 6-F delivery guiding sheath, and entered the plug. The AVP-1 was then packed with hydrogel micro coils.
We compared number of coils used, embolization length, embolization time, volume embolization ratio, and embolic material cost between the groups.
Results: The CIP method achieved shorter embolization length with fewer coils used compared to CCE. The CIP method decreased the cost of total embolic materials.
Conclusion: The CIP method can achieve shorter embolization length with fewer coils used compared to CCE.
