[Inflammatory aneurysms of the subrenal aorta. Histopathological, diagnostic and therapeutic aspects].
Inflammatory abdominal aneurysms (AIAA) represent a clearly defined clinical entity with an incidence ranging between 1.2% and 15%. In spite of the increasing number of observations reported in recent years, the etiopatholgenesis and natural history have not been defined. The lesion can present in an acute, subacute or chronic manner and the histopathological studies reveal prevalently two components: an inflammatory infiltrate and a diffuse fibrosis, in varying degree. This study aimed to analyze the more recent imaging procedures in order to correctly diagnose this lesion. In our experience the incidence of AIAA is about 2.5%. On the basis of macro microscopic pictures the authors divided patients into two groups: one constituted by the acute or subacute inflammatory forms, the other by chronic clear inflammatory aneurysms. All patients underwent on operative treatment. The surgical adopted techniques and the obtained results are reported.
