33. 下列關於Intestinal ischemia 的敘述，何者為是？
(1) CT has largely replaced plain film study of the abdomen for diagnosis of
acute mesenteric ischemia and is used to identify arterial and venous
thromboses as well as to evaluate bowel injury.
(2) Among the types of Intestinal Ischemia, acute mesenteric ischemia is more
frequent than colon ischemia.
(3) CT angiogram is highly accurate in the detection of occlusive disease of the
SMA but is not as reliable for nonocclusive mesenteric ischemia.
(4) Most patients with acute mesenteric ischemia have acute abdominal pain.
(5) Unexplained abdominal distention or GI bleeding may be the only
indications of acute mesenteric ischemia when pain is absent, especially
when acute mesenteric ischemia is caused by nonocclusive mesenteric
ischemia.
