title: [Diagnostic imaging following reconstructive surgery of the arteries of the legs. Angiodynography versus digital subtraction angiography].
abstract: Fifty-three patients were examined by angio-dynography and angiography in a prospective study following vascular surgery of the lower extremities. The question of patency was correctly solved in all cases. A-V communications could be localised in eight out of nine cases. Evaluation of anastomoses is equally accurate by both methods; all angiographically demonstrated stenoses were also visible on sonography. Aneurysms at the anastomoses and peri-vascular fluid collections were better shown by angio-dynography, as might have been expected. The demonstration of the distal run-off, following femoro-crural bypass, presented a problem; in eight cases this could not be achieved because of technical difficulties. Surprisingly, angio-dynography proved superior in demonstrating large distal A-V shunts. Our experience so far indicates that angio-dynography may be used as an alternative to angiography for certain specific indications (bypass patency, large A-V shunts and complications around the anastomosis). Demonstration of vessels, and particularly of distal femoral bypasses can be improved by using the "slow-flow technique".
