Resection for abdominal aortic aneurysm (AAA) is being performed with decreasing mortality and morbidity. A retrospective study on 82 consecutive patients with AAAs admitted during the period 1974-1977 shoowed that 66 had a non-ruptured aneurysm and 16 a ruptured aneurysm. The mean age of the patients was 66,7 years. Concomitant disease was frequent. Operative mortality aneurysms and 37% in the group with ruptured aneurysms.

Thirty patients thought to have an atherosclerotic thoracic aneurysm or chronic aortic dissection were evaluated by computed tomography (CT) and the findings compared with those from conventional radiography, thoracic aortography, and surgery. In all cases, CT defined the lesion and correlated well with angiography. Staging of atherosclerotic aneurysms was possible, and CT also demonstrated the relationship between true and false lumina in aortic dissections; however, aortography was often necessary to differentiate a dissection from an aneurysm or for staging. The relative value of CT and aortography is discussed.

AbstractThe operative death rate for resection of nonruptured aneurysm of the abdominal aorta has been reduced to less than 10 percent, but the figure for treatment of ruptured aneurysm has remained high. Long-term follow-up indicates that patients surviving operation have a near-normal life expectancy. Operative technic and postoperative complications are discussed.

Objective To investigate the diagnosis value of aortic aneurysm with MRI.Methods Two radiologist analysed 312 cases MRI of clinically suspected aortic aneurysm retrospectively,and screening 198 cases of aortic aneurysm,analysed by double blind method.Among these patients,there were 112 male and 87 female,aged 9 to 82 years(mean age of 50.4 years).86 cases underwent X-ray angiography(XRA) examination,and 79 cases with operation.Results The MRI showed 22 cases of ture aneurysm,19 of false aneurysm,127 of dissecting aneurysm,26 of Marfan′s syndrome and 4 of compound aneurysm.Contrast analysed the XRA,CT and operation,the sensitivity and accuracy of MRI is 99% and 94%.Conclusion The MRI is an accurate and safe method for detecting aortic aneurysm.

The study was undertaken for aortic evaluation and to see its usefulness for assessing aortic aneurysm,aortic dissection and pseudoaneurysm by spiral CT angiography (CTA). A total of 28 patients with aorticaneurysm (n=19), aortic dissection (n=5) and aortic pseudoaneurysm (n=4) were included. CTA findingswere compared with ultrasonography in 14, digital subtraction angiography (DSA) in 14, MRI in 9; andsurgical findings in 12 patients. CTA was an excellent imaging modality for comprehensive evaluation ofaortic aneurysm, dissection and pseudoaneurysm combining the advantage of conventional contrast enhancedCT axial images and those of angiography in the form of 3D reformatted images.Key Words: Aortic aneurysm, dissection, pseudoaneurysm, CT angiography.

An evaluation of the management of patients with aneurysm of the aorta seems timely because of new and promising methods of treatment. The risks of nonoperative and operative treatment are presented from the experiences with 101 patients admitted to the Hospital of the University of Pennsylvania during the years 1950 through 1955. Follow-up data indicate that the mortality of nonoperative treatment is considerably greater than that of excision of the lesion, in spite of the poor operative risk of many patients in this group. The nonoperative mortality within 1 year of diagnosis was approximately 50 per cent. Many of these patients died of rupture of the aneurysm.
