Why the study?
Does splanchnic blood flow measurement before and after a test meal differentiate patients with abdominal angina from controls and normalize after arterial reconstruction?
Does splanchnic blood flow measurement before and after a test meal differentiate patients with abdominal angina from controls and normalize after arterial reconstruction?
Splanchnic blood flow measurement before and after a test meal may serve as a diagnostic test for abdominal angina and to assess the success of arterial reconstruction.
SBF response to meals may support abdominal angina diagnosis; leaves open clinical adoption pending prospective validation.
The diagnostic value of determining the splanchnic blood flow (SBF) and oxygen uptake before and after a test meal in patients suspected of abdominal angina was investigated in 15 patients with unexplained abdominal pain. Six patients with typical abdominal angina and occlusive lesions of two or three splanchnic arteries were investigated before and after successful arterial reconstruction. Five patients with less severe arterial lesions were classified as suspected of abdominal angina and four patients with eventual normal arteriography served as controls. No significant difference was found in fasting SBF between the three groups. Postprandial SBF rose in the controls and in the abdominal angina suspected group, but not in the patients with abdominal angina. After arterial reconstruction fasting SBF was higher than before and postprandial SBF rose to the level of the controls. No difference in oxygen uptake before or after test meal was seen in any of the groups or after arterial reconstruction.
