1 Reconstructive surgery for segmental arterial mediolysis involving both the internal carotid artery and visceral arteries  Hideaki Obara, MD, PhD, Kenji Matsumoto, MD, PhD, Yoshiaki Narimatsu, MD, PhD, Hitoshi Sugiura, MD, PhD, Masaki Kitajima, MD, PhD, Toshihiro Kakefuda, MD, PhD  Journal of Vascular Surgery  Volume 43, Issue 3, Pages (March 2006) DOI: /j.jvs Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 A, Contrast-enhanced computed tomographic (CT) scan shows an aneurysm, with mural thrombus, of the left carotid artery (arrow). B, Angiogram of the left carotid artery shows a fusiform aneurysm of the internal carotid artery (arrow) with narrowing (arrowhead) in the proximal portion.

3 Fig 2 A, Contrast-enhanced computed tomography scan shows a large extrahepatic artery aneurysm (arrow), with mural thrombus, and a celiac artery aneurysm (arrowhead). B, Selective celiac artery angiogram shows a saccular hepatic artery aneurysm (black arrow) with narrowing (arrowhead) in the proximal portion, as well as a fusiform celiac artery aneurysm (white arrow). C, Selective superior mesenteric artery angiogram shows narrowing of the distal portion of the superior mesenteric artery associated with a poststenotic fusiform dilatation (arrow).

4 Fig 3 A, Abdominal aortogram shows good postoperative patency of the vein graft (white arrowhead), right (black arrow) and left (white arrow) hepatic arteries, and splenic artery (black arrowhead). B, Angiogram of the left carotid artery shows good postoperative patency of the vein graft (black arrow).

5 Fig 4 A and B, Pathology studies of resected arterial wall specimens show multiple segmental mediolysis lesions (arrows) of the muscular and elastic fibers of the media (elastica-van Gieson stain; magnification × 20). A, Proximal portion of the resected left internal carotid artery aneurysm. B, Proximal portion of the resected common hepatic artery aneurysm. C, Pathology study of the resected common hepatic artery aneurysm shows an organized dissection (arrowheads) (hematoxylin and eosin stain; magnification × 20).
