Two cases are reported in which gastric cardia pseudomasses associated with sliding hiatal hernias were seen on computed tomography done for evaluation of esophageal carcinoma.

Digital video subtraction angiography (DVSA) has been employed to study a variety of peripheral vascular problems, using equipment developed at the University of Wisconsin. The technique is relatively simple and safe and has good patient acceptance. Experience indicates that in selected patients it is a satisfactory alternative to standard arteriography for screening and for definitive evaluation and on occasion may yield information not obtainable with conventional methods. It can aid in the performance of transluminal angioplasty and is suitable for serial evaluation of atherosclerotic vessels and bypass grafts.

The records of 518 patients with ovarian cancer between 1969 and 1977 were retrospectively analyzed. During the course of their disease, 127 patients developed intestinal obstruction. Obstructions occurred in 17 (13.9%) of stage I patients, 17 (16.8%) of stage II patients, 72 (30.0%) of stage III patients, 20 (36.4%) of stage IV patients, and in 1 of the 3 patients whose initial staging was unknown. At advanced stages, patients developed intestinal obstruction more quickly. Patients deemed terminal and thus inoperable survived an average of 2 months. Those treated surgically for these obstructions survived an average of 7 months. Colostomy patients lived for 6.6 months. The degree of obstruction, partial or complete, was not significantly related to survival. The median time of survival for all patients with obstruction was 112 days.

Intra-arterial infusion of 5 FU is used in the treatment of a variety of neoplasms. Direct infusion of 5 FU into the arterial blood supply of the tumor allows the dose to be increased while avoiding the expected increase in systemic side effects. However, organs and tissues supplied by the vasculature infused, experience disproportionate toxicity. At our institution, between January, 1977, and October, 1980, 411 patients received intra-arterial infusions of 5 FU through percutaneously-placed catheters positioned within the hepatic artery. Sixty-three percent of these patients developed signs or symptoms thought clinically to represent gastrointestinal toxicity. In 25% of these, symptoms were sufficiently severe to warrant GI evaluation; 67% of the latter demonstrated morphologic changes of the stomach and small bowel attributable to 5 FU toxicity. In 20% of the 411 patients, it was necessary to stop the 5 FU infusion because of gastrointestinal toxicity. Abnormalities were predominantly confined to the stomach and duodenum and consisted of; 1) loss of distensibility; 2) hypersecretion; 3) mural and mucosal thickening; and 4) ulceration. These changes developed within two weeks after the start of 5 FU infusion and occurred in portions of the gastrointestinal system supplied by the vasculature being perfused. The rapid onset and distribution of the changes implicates 5 FU as the etiologic agent. In this report, we will describe and illustrate the changes seen in this group of patients. In our opinion, these abnormalities are best demonstrated through the use of double contrast examinations. In patients receiving intra-arterial infusion of 5 FU who develop gastrointestinal signs or symptoms, these studies should be promptly performed.

Following several years of development and testing using animals, a digital image processor designed to perform generalized subtraction imaging tasks has been interfaced to an image-intensified television fluoroscopy apparatus in the University of Wisconsin Clinical Sciences Center. So far, 175 patients have been examined using three time-subtraction modes. In Mask-Mode-Radiography, images of opacified arteries are subtracted from a mask image obtained just prior to the arrival of iodine injected into an antecubital vein. Fully processed subtraction images are obtained at a rate of about one per second and stored on a video disc in real time. This mode is used for all arteries outside of the heart and may be ECG-gated for cardiac imaging. Left ventricular motion is well visualized in Mask Mode Fluoroscopy. In this mode the mask is taken prior to the injection of contrast. Then 60 subtraction images per second are stored on video tape. For wall motion studies this can be done at conventional fluoroscopic exposure levels. We have had limited success in seeing coronary bypass grafts and coronary arteries, but further improvements are needed. In Time Interval Difference Mode short term changes in iodine concentration are displayed. This mode is obtained from Mask Mode Fluoroscopy by reprocessing.

The clinical experience with selective superior mesenteric arterial portography employing an alpha blocking agent (phentolamine) and beta stimulating agent (isoproterenol) used in combination to produce improved portal venous system opacification is described. In fourteen of sixteen studies, a greater degree of opacification of the portal venous system occurred utilizing this drug combination. Various anatomic and physiologic factors, including superior mesenteric artery pressure and peripheral blood pressure before and immediately after the injection of the drug combination were used to evaluate the results. Side effects were minimal and usually consisted of transient tachycardia.

Both techniques provide almost identical radiographic information in most cases. Although a percutaneous transthoracic intraparenchymal study is simpler to perform, the hepatic wedge technique (via the femoral vein) is subject to fewer artifacts of pressure measurement and also allows evaluation of free hepatic vein and inferior vena caval pressures.Article HistoryPublished in print: Feb 1972 FiguresReferencesRelatedDetailsCited ByClinical Investigations in GastroenterologyMalcolm C.Bateson, Ian A.
