2. Fig 1
Scanning electron micrograph of the intimal surface of a clipped vein–artery anastomosis. The luminal surfaces of the carotid artery (CA) and the vain graft (SVG) are covered by continuous endothelium, and the anastomotic site (An) is indistinguishable. (×250 before 57% reduction.)

3. Fig 2
Scanning electron micrograph of the intimal surface of a sutured vein–artery anastomosis. The suture material (arrows) remains clearly visible inside the lumen of the vessel. (×55 before 57% reduction.) The rectangle delineates the area further magnified in Figure 3. Abbreviations as in Figure 1.

4. Fig 3
Close to the suture (Su) exit point, significant amounts of platelets and red blood cells are present (short arrows). Endothelial cells (EC) are seen attempting to cover the line of anastomosis (long arrows). (×1,200 before 57% reduction.) The rectangle delineates the area further magnified in Figure 4.

5. Fig 4
Significant amount of platelets, red blood cells (arrow), and fibrin are forming microthrombi at the site of endothelial break near the suture (Su). (×5,000 before 57% reduction).

6. Fig 5
The line of the anastomosis (An) in this sutured specimen is open, and the subendothelial matrix remained exposed, with extensive fibrin and platelet deposition on its surface (arrows). (×1,200 before 57% reduction.) Other abbreviations as in Figure 1.
