1 Coexistence of cystic medial necrosis and segmental arterial mediolysis in a patient with aneurysms of the abdominal aorta and the iliac artery  Makoto Yamada, MD, Masahiro Ohno, MD, Taroh Itagaki, MD, Toshihiro Takaba, MD, Takaaki Matsuyama, MD  Journal of Vascular Surgery  Volume 39, Issue 1, Pages (January 2004) DOI: /j.jvs

2 Fig 1 A contrast-enhanced computed tomographic scan shows an infrarenal abdominal aortic aneurysm (arrow) contiguous with a left common iliac aneurysm (arrows), both without luminal thrombus. Journal of Vascular Surgery  , DOI: ( /j.jvs )

3 Fig 2 A, Photomicrograph of segment of the left common iliac aneurysm shows marked mediolysis of muscular and elastic fibers of the media. Detachment of the intima and media from the adventitia formed an arterial wall gap (arrows) bridged by fibrin-like exudates (Elastica van Gieson, original magnification, ×12.5). B, Magnified view of boxed area in A shows variable-sized vacuoles; mucoid material is noted within the entire media (Alcian blue, original magnification, ×200). Journal of Vascular Surgery  , DOI: ( /j.jvs )

4 Fig 3 A, Photomicrograph of the wall of the abdominal aortic aneurysm disclose disruption of elastic fibers. There is an area of medial interruption (arrows) (Elastica van Gieson, original magnification, ×12.5). B, Magnified view of boxed area in A shows severe disruption of elastic fibers (Elastica van Gieson, original magnification, ×100). C, Magnified view of boxed area in A discloses mucopolysaccharide-filled cysts throughout the entire media (Alcian blue, original magnification, ×100). Journal of Vascular Surgery  , DOI: ( /j.jvs )
