Ruptured arteriosclerotic aneurysm of the splenic artery.

A case of arteriosclerotic aneurysm of the splenic artery with rupture into the transverse colon resulting in secondary perforation of the cecum is presented. Symptomatology, diagnosis and treatment of aneurysms of the splenic artery are briefly illustrated. Aneurysm of the splenic artery must be suspected by the presence of uncharacteristic upper abdominal pain and the annular calcification in the left upper quadrant on roentgenogram. The diagnosis is verified by arteriography. Operation of all symptomatic splenic artery aneurysms is recommended. Asymptomatic aneurysms measuring more than 3 cm in diameter and aneurysms with radiographic evidence of enlargement, should be operated too.

Acute segmental gastro-intestinal gangrene probably of clostridial origin. Report of a case.

A 29-year-old female suffering from acute terminal ileitis was subjected to laparotomy undertaken on the tentative diagnosis of acute appendicitis. The appendix was found to be normal and was removed. The course was complicated with segmental gastro-intestinal gangrene with fatal outcome. The involvement of histotoxic clostridial infection as a causative factor is discussed.

Non-invasive measurement of stroke volume and left ventricular ejection fraction. Radionuclide cardiography compared with left ventricular cardioangiography.

The stroke volume (SV) was determined by first passage radionuclide cardiography and the left ventricular ejection fraction (LVEF) by multigated radionuclide cardiography in 20 patients with ischemic heart disease. The results were evaluated against those obtained by the invasive dye dilution or thermodilution and left ventricular cardioangiographic techniques. In a paired comparison the mean difference between the invasive and radionuclide SV was -1 ml (SED 3.1) with a correlation coefficient of 0.83 (p less than 0.01). Radionuclide LVEF values also correlated well with cardioangiographic measurements, r = 0.93 (p less than 0.001). LVEF determined by multigated radionuclide cardiography was, however, significantly lower than when measured by cardioangiography, the mean difference being 6 per cent (p less than 0.001). These findings suggest that radionuclide determinations of SV and LVEF are reliable. The discrepancy between the non-invasive and invasive LVEF values raises the question, whether LVEF is overestimated by cardioangiography or underestimated by radionuclide cardiography.
