The cuffed renal vein technique significantly shortened the operation time.

<p><b>A</b>) Total operative time was reduced with the new cuffed renal vein technique, as evidenced by the significantly reduced times required to carry out the renal anastomoses (p<0.001,). <b>B</b>) The clamping times for vena cava and aorta were dramatically reduced in cuffed renal vein technique compared to the classical technique (p<0.001), and consequently the recovery of lower limb activity was significantly quicker with cuffed renal vein technique (p<0.001). <b>C</b>) The survival improved significantly from 75% with the classical technique to 93.3% with the cuffed renal vein technique (P < 0.001).</p

The cuffed renal vein technique.

<p>The renal vein was cleaned for insertion through 22G intravenous catheter (outer diameter 1.1 mm), using a cuff length of about 0.7-0.9 mm and an equal vein length, which was folded back and tied. </p

Polybacterial infection significantly increased atherosclerotic plaque growth in the ascending aorta and the aortic root.

<p>(A). Total plaque area of infected mice was elevated at both 12- and 24 weeks of infection, but was significant compared to controls at 24 weeks of infection (p < 0.05). (B). Intimal/medial layer thickness ratio of infected mice was increased relative to sham-infected mice at both 12- and 24 weeks of infection, although not significant (p = 0.1599 and 0.1339). (C). CD3⁺ T cell counts were significantly higher in 24 week–infected mice than sham-infected mice. (D). H & E stained aortic section illustrates large plaques in infected mice. (E).
