Umbilical arterial catheters in the high position reduce the lumen of the aorta and may thereby impair blood supply to the intestine. Thirty-two preterm and three term infants were studied with an umbilical arterial catheter by colour and duplex Doppler sonography. The diameter of the aorta at the level of the coeliac axis was measured to calculate the reduction of the cross-sectional area of the aorta by the catheter. Blood-flow velocities were measured in the coeliac axis, the superior mesenteric artery and the anterior cerebral artery before and after removal of the catheter. The umbilical arterial catheter reduced the cross-sectional area of the aorta by 3.4-27.2% (mean 10.1%). There was no difference between blood-flow velocities in the coeliac axis and the superior mesenteric artery before and after removal of the umbilical arterial catheter, indicating that the catheter did not impair blood supply to the intestine.

D007422	Intestines	The section of the alimentary canal from the STOMACH to the ANAL CANAL. It includes the LARGE INTESTINE and SMALL INTESTINE.	Intestine
D001783	Blood Flow Velocity	A value equal to the total volume flow divided by the cross-sectional area of the vascular bed.	Blood Flow Velocities,Flow Velocities, Blood,Flow Velocity, Blood,Velocities, Blood Flow,Velocity, Blood Flow
D002404	Catheterization	Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions.	Cannulation,Cannulations,Catheterizations
D002445	Celiac Artery	The arterial trunk that arises from the abdominal aorta and after a short course divides into the left gastric, common hepatic and splenic arteries.	Arteries, Celiac,Artery, Celiac,Celiac Arteries

D014469	Umbilical Arteries	Specialized arterial vessels in the umbilical cord. They carry waste and deoxygenated blood from the FETUS to the mother via the PLACENTA. In humans, there are usually two umbilical arteries but sometimes one.	Arteries, Umbilical,Artery, Umbilical,Umbilical Artery
D017538	Mesenteric Artery, Superior	A large vessel supplying the whole length of the small intestine except the superior part of the duodenum. It also supplies the cecum and the ascending part of the colon and about half the transverse part of the colon. It arises from the anterior surface of the aorta below the celiac artery at the level of the first lumbar vertebra.

D018615	Ultrasonography, Doppler, Color	Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.
