(a) inferior phrenic artery.

Ligation of the inferior mesenteric artery (IMA) will cause ischemia to the large bowel but not the small bowel.

The IMA may be sacrificed without colonic ischemia because of collateral circulation via the marginal artery and hemorrhoidal arteries.

The superior mesenteric artery (SMA) may be sacrificed without causing bowel ischemia.

Neither the superior nor the inferior mesenteric arteries may be sacrificed without causing bowel ischemia.

The IMA may be sacrificed without colonic ischemia because of collateral circulation via the ileocolic artery.

A sudden onset unilateral right-sided varicocele should prompt retroperitoneal imaging.

The right testicular vein typically drains into the inferior vena cava (IVC).

The left testicular vein typically drains into the left renal vein.

The left ovarian vein typically drains into the IVC.

Unilateral varicoceles are more common on the left side.

Superficial then deep right inguinal nodes

Primarily to the interaortocaval nodes with some drainage to the right paracaval nodes

Only to the interaortocaval nodes

Left para-aortic with some drainage to the interaortocaval nodes

Interaortocaval nodes primarily with some drainage to the right paracaval nodes and a small but appreciable amount of drainage to the left paraaortic nodes
