Objective To summarize our experience of the diagnosis and treatment in patients with abdominal aortic aneurysm(AAA).[WT5”HZ]Methods [WT5”BZ]From 1980 to 1999 sixty five AAA patients were hospitalized with 40 cases of general type, 18 cases of rupture type,4 cases of inflammatory type and 3 cases of infective type. In situ artificial graft transplantation was performed in 62 cases and nonanatomy pathway in 2 cases. The remaining one with inflammatory type was treated by interventionel therapy.[WT5”HZ]Results [WT5”BZ]57 cases were cured and were followed up from 1 to 12 years without complications.Death occurred in 7 cases.[WT5”HZ]Conclusions [WT5”BZ]The abdominal pulsate mass should draw much attention. Ultrasound is the selected examination and DSA, helix CT are accurate image appliance. It can elevate the curative ratio and decrease the mortality through rational operation based on the location, type and individual condition of AAA patients.
