A technique of percutaneous catheterization from the left axillary artery of the abdominal aorta and its branches, in the older age group, is presented. This modification is necessary because of the altered relationship between the left subclavian artery and the descending aorta with advancing age. The ease of performance and lack of serious complications recommend this procedure for investigating thoracic and abdominal aortic lesions when the femoral route is unavailable.
