Abstract:
Purpose To explore the clinical and imaging characteristics of rupture death cases of pseudoaneurysm,and to enhance the awareness of prevention strategies,early diagnosis and treatment.Materials and Methods Clinical imaging data of six patients with pseudoaneurysm rupture and death in the Second Affiliated Hospital of Air Force Military Medical University from January 2016 to December 2021 were retrospectively analyzed.Results CT and MRI findings of false aneurysms were circular or irregular tumor bodies that protrusion the tumor bearing artery,and could be seen to communicate with the tumor bearing artery.There might be thrombosis in the tumor body,compression displacement of the adjacent tumor bearing artery,thinning or thickening of the lumen.Imaging features of six cases with pseudoaneurysm showed that the location,shape,size,size of rupture,relationship with parent artery and surrounding tissue structure,with clear and definite diagnosis.Two cases of pseudoaneurysm of aortic arch was formed after swallowing date kernel by mistake and removing under endoscope.Pseudoaneurysm formation was caused by trauma in one case,after intervention in one case,and with no clear reason in one case.In one case,pseudoaneurysm of cavernous segment of left internal carotid artery was caused by erosion of adjacent vessel wall by intracranial nonspecific infection.Before death,all 6 cases had sudden symptoms of hematemesis or nosebleed,suggesting pseudoaneurysm rupture.Conclusion The rupture of pseudoaneurysm has a high mortality rate.CT and MR can objectively show the imaging manifestations of pseudoaneurysm,with certain clinical value.
