CT of small bowel ischemia

摘要: We evaluated the computed tomographic (CT) features of small bowel (SB) ischemia and necrosis correlated findings with clinical outcome or patient prognosis. Sixty-eight surgically angiographically proved cases SB were retrospectively reviewed. The CT intestinal divided into three groups: (A) thinned wall poor enhancement, intramural gas, portal venous gas; (B) thickened without superior mesenteric vein thrombosis; (C) thrombosis intussusception. factors included mucosal enhancement pattern, dilatation, edema, evidence narrowing occlusion artery vein. rates mortalities compared chi-square test. Oral contrast material was not administered. Intramural gas dilatation associated a higher rate (eight eight, 100%, 17 21, 81%, respectively) in group A. Poor indicated groups B (six seven, 86%) C (12 12, 100%) than did normal enhancement. Only accompanied mortality 75%). are useful signs necrosis. would indicate
