Amplatzer Vascular Plug With Endologix AFX Lining for Visceral Re-Entry Closure in a Patient With Chronic Type B Aortic Dissection.

PURPOSE: To demonstrate the efficacy of a combination of Amplatzer vascular plug (AVP2) and Endologix AFX for a visceral entry closure.

CASE REPORT: A 70-year-old woman with treated chronic type B aortic dissection was seen to have sac enlargement. An isolated residual tear was observed at the origin of the celiac artery. A 12 mm AVP2 was successfully deployed for the entry closure. Angiography after the plug deployment still demonstrated residual flow to the false lumen. Hence, an Endologix AFX VELA proximal endograft was deployed, covering the AVP membrane and leaving no endoleak.

CONCLUSION

Deployment of a vascular plug with Endologix AFX lining was efficacious for securing complete closure of an entry tear at the origin of the celiac artery in our patient.

CLINICAL IMPACT: Vascular plugs are reported to be effective for closing small entries, although their effectiveness is limited when the entry site is not located on the flat intima, or in a high-flow situation. In the presented case, an isolated entry tear at the origin of the celiac artery was successfully closed with a vascular plug following Endologix AFX stent-graft lining of the true lumen.
