Abstract
BackgroundThis case report demonstrates the value of IMPEDE-FX plugs in an embolization procedure of a false lumen of an infrarenal post-dissection aneurysm.Case presentationA 69-year-old patient was treated with mitral valve replacement, complicated by a Stanford type-A dissection. After 9 years he presented with an enlarging infrarenal post-dissection aneurysm. The false lumen was embolized using multiple IMPEDE-FX plugs as part of the treatment in addition to embolization of the inferior mesenteric artery and overstenting of the re-entry in the right iliac artery. At 15 months the CTA showed a fully thrombosed false lumen and remodeling of the true lumen.ConclusionsThe false lumen of an infrarenal post-dissection aneurysm can successfully be embolized using IMPEDE-FX embolization plugs as part of the treatment strategy. Prospective trials on patients with non-thrombosed false lumina are indicated.
Highlights
This case report demonstrates the value of IMPEDE-FX plugs in an embolization procedure of a false lumen of an infrarenal post-dissection aneurysm.Case presentation: A 69-year-old patient was treated with mitral valve replacement, complicated by a Stanford type-A dissection
We describe a case of an infrarenal postdissection aneurysm that was successfully embolized using multiple IMPEDE-FX embolization plugs
The volume of the true lumen showed a similar decrease, with a preoperative volume of 102.4 cm3, and a volume of 109.2 cm3 and 87.5 cm3 at 1 and 8 months, respectively. This case demonstrates the successful use of IMPEDEFX embolization Plugs to obliterate a false lumen of an infrarenal post-dissection aneurysm
Summary
This case demonstrates the successful use of IMPEDEFX embolization Plugs to obliterate a false lumen of an infrarenal post-dissection aneurysm. This method could provide an alternative technique for endovascular embolization of a larger false lumen in patients with an aortic dissection, in the thoracic area. The shape of the true lumen changed and the volume decreased by about 15%, after a minor increase, which may be explained by the decrease of pressure in the false lumen This case suggest that IMPEDE-FX embolization plugs can be used successfully to embolize a false lumen of a post-dissection aneurysm, with a larger diameter.
