2. Fig. 1
Photomicrograph shows the pathologic features of the omental vessels. The acute changes are in the right half with a large mass of recent thrombus (T) overlying the acutely torn vessel wall. The adjoining area shows a segment with preserved medial smooth muscle and a narrow full thickness acute tear (thin arrow). The perivascular tissue shows recent hemorrhage. The chronic changes are seen in the left half of the photomicrograph. This segment of vessel wall shows aneurysm formation with part of the wall (curved arrow head) showing virtually no elastic tissue and no medial muscle whereas the adjoining segment (arrow) shows compaction and duplication of medial elastic tissue (heavy black lines) and loss of medial muscle. The media also shows small areas of mediolysis (open arrowhead). M, Normal arterial media; T, thrombus. (Hematoxylin-eosin stain; original magnification × 100.)

3. Fig. 2
Higher magnification of a segment of arterial wall. The acute full thickness tear (thin arrow) has some fibrin and red blood cells in it. The adventitia shows recent hemorrhage (H). The areas of mediolysis (open arrowhead) show loose, edematous looking acid mucopolysaccharide rich tissue with loss of medial smooth muscle cells. M, arterial media; H, hemorrhage. (Hematoxylin-eosin stain; original magnification × 250.)
