Deflation of a Sengstaken tube balloon facilitating catheterization of the celiac artery.
Selective catheterization of the celiac axis may be difficult when the lumen of the artery is compromised. The presence of an inflated compression balloon in the stomach may narrow the artery, presumably by placing tension on the median arcuate ligament of the diaphragm. Deflation of the gastric balloon can facilitate catheterization by relieving the extrinsic pressure on the artery.
