The dual-source CT analysis of vascular lesions causing abdominal pain / 实用放射学杂志

ABSTRACT

Objective With the CT analysis of vascular lesions which caused abdominal pain,to improve the radiologist’s understanding of this disease,and to reduce the rate of misdiagnosis.Methods The CT data of 69 cases with vascular lesions which caused abdominal pain were analysis retrospective.Results In the vascular lesions causing abdominal pain,the occlusions of the superior mesenteric artery and vein were the most common,a total of 30 patients (43%),and the most common cause of occlusion was thrombosis (27%);There were the abdominal aorta dissection (Ⅰ+Ⅲ type+limitation)in 1 5 cases,abdominal aorta and/or iliac artery vein multiple ulcers in 9 cases (13%);Type B intramural hematoma in 6 cases (8%);Simply superior mesenteric artery dissection in 5 cases;Other less common splenic arterial thrombotic occlusion in 2 cases,pure splenic artery occlusion in 1 case and renal artery dissection in 1 case.7 cases were missed lesions,the main reason for radiologists to focus placed in the abdominal cavity prone to abdominal pain caused by solid organ or cavity organ,while ignoring the observation in the scanning range of the abdominal aorta and its main branches of the artery,lack of knowledge and experience of the lesions,and therefore not to see the consciousness or habits.Conclusion Vascular causes is an important reason causing abdominal pain.In patients with abdominal pain who underwent CT examination,if the cause of the gut and other abdominal organs can be exclused,the possibility of vascular etiology should be considered,and we should carefully observe intraabdominal artery and vein to exclude the possibility of this disease.
