When flow in the supe- rior or inferior vena cava is blocked, anastomoses between their tributaries, that is, the thoracoepi- gastric vein, may pro- vide collateral circula- tion, allowing the ob- struction to be bypassed.

The blood then flows to into the systemic system at places of portal-systemic anastomo- sis, producing varicose veins. Caput medusae is caused by the veins of the anterior abdominal wall becoming dilated from portal hypertension. A common method for reducing portal hypertension is to divert blood from COA the portal system to the systemic venous system by creating a communication between the portal vein and the inferior vena cava. © 2008 Lippincott Williams & Wilkins front.card2.37.qxd 12/5/06 1:22 PM Page 1 Abdomen 2.37 Viscera of Posterior Abdominal Wall 1 2 3 4 5 6 7 8 Grant’s back.card2.37.qxd 12/4/06 3:28 PM Page 1 Viscera of Posterior Abdominal Wall 1. celiac ganglion 2. celiac trunk 3. spleen 4. right suprarenal gland 5. right kidney 6. right testicular artery and vein 7. right ureter 8. right external iliac artery and vein Nephroptosis (dropped kidney) is the result of an abnormally mobile kidney. In nephroptosis, when a person is standing, the ureter, which is of normal length (unlike in ectopic kid- ney) may become coiled and/or kinked. Renal transplantation is a well-established operation to re- place failing kidneys. The transplanted kidney is placed in the iliac fossa for support. © 2008 Lippincott Williams & Wilkins.
