title: Non-atherosclerotic aorto-arterial thrombosis: A study of 30 cases at autopsy.
abstract: BACKGROUND
  Aorto-arterial thrombosis is very often associated with atherosclerotic and/or aneurysmal changes. Thrombosis, unrelated to these changes is infrequent.
  
  
  OBJECTIVE
  To evaluate the clinical presentation and aetiopathogenesis of aorto-arterial thrombosis, unrelated to atherosclerosis and aneurysms.
  
  
  METHODS
  A retrospective study of 30 autopsied cases of non-atherosclerotic and non-aneurysmal aorto-arterial thrombosis collected over a period of 14 years was carried out.
  
  
  RESULTS
  There were 23 males and seven females and majority presented in the third to fourth decades of life with clinical features of acute abdomen or lower limb gangrene. Abdominal aorta as the site of thrombosis was observed in 46.5% cases. The causes were attributed to hypercoagulable states and changes in the aortic wall. No aetiology could be identified in 5 patients (16.6%. Associated tuberculosis was seen in six cases.
  
  
  CONCLUSIONS
  Non-atherosclerotic aortic thrombosis is a heterogeneous group of disorders. Young and even elderly patients with symptoms related to abdominal ischaemia or peripheral vascular disease should be investigated thoroughly for hypercoagulable states and aortic pathology.
