    Abstract:
    PURPOSE: The aim of this study is to present an easy and quick technique for embolization of the inferior mesenteric artery (IMA) during endovascular aneurysm repair (EVAR). TECHNIQUE: We performed IMA embolization using a conventional EVAR device alone with the femoral artery approach during EVAR, which has not been reported previously. First, a 16F or 18F DrySeal Sheath is inserted from the femoral artery into the site around the IMA. Second, cannulation is performed in the IMA with an angiography catheter having a 0.038-inch inner lumen that is used for gate cannulation during EVAR. Third, IMA embolization is performed using the Amplatzer Vascular Plug 4 (AVP4). The use of the DrySeal Sheath facilitates cannulation of the IMA, and its combination with a stent-graft balloon allows the AVP4 to be placed at the root of the IMA without deviation of the catheter. The success rate of the procedure was 90.9% (30/33 cases). The median procedure time was 11.6 min. No complications due to IMA embolization were noted. CONCLUSION: This procedure enables safe and quick placement of the AVP4 in the IMA using the catheter insertion approach from the femoral artery, which has been conventionally regarded as difficult.
