The value of the lateral projection in preoperative assessment of abdominal aortic aneurysms by IV-DSA.
25 consecutive patients with known abdominal aneurysms were examined pre-operatively by IV-DSA. In all patients a lateral view was taken in addition to the standard posteroanterior view. The state of the visceral arteries was best assessed on the lateral projection. In 24% of examinations the renal arteries could not be visualised satisfactorily in the lateral view. In 37% of the 19 patients in which the distance between the renal arteries and the aneurysm neck could be measured there was a greater than 1 cm discrepancy between the two projections indicating that both views are necessary for accurate measurement. It is concluded that both a lateral and a postero-anterior projection should be routinely taken for IV-DSA in pre-operative assessment of abdominal aortic aneurysms.
