Abstract
The importance of the preoperative diagnosis of aneurysms of the celiac axis vessels is briefly reviewed, and the first instance of successful preoperative angiographic demonstration of an aneurysm of the left gastric artery is reported. The most important feature of these lesions is the great likelihood of their rupture into the peritoneal cavity or erosion into an adjacent viscus to produce sudden or gradual hemorrhage. Left gastric artery aneurysm permits a good surgical prognosis as opposed to hepatic artery aneurysm. Preoperative angiographic diagnosis of either of these lesions definitely provides a better surgical approach and prognosis. Since the commonest etiology of these lesions is probably arteriosclerosis, their diagnosis should be suggested by the presence of a cyst-like right upper quadrant calcification outside the biliary system.
