title: [Intravenous digital angiography in the control of the patency of extra-anatomical bypasses of the legs].
abstract: The authors report their experience over 58 cases of extra-anatomical by-pass for revascularity of lower limbs (31 axillo-femoral, 21 femoro-femoral, 2 femoro-popliteal, 4 axillo-femoral) checked using intravenous digital angiography (IDA). This method is useful for its poor invasivity. As a matter of fact intravenous peripheral injection of contrast medium is proved to be sufficient. Moreover it allows clear evidence of anastomosis morphology and functionality both peripherally and proximally. Peripheral flow is also well seen when by-pass works. IDA fills now an area where traditional angiography was not employed for the difficulties in using arterial way. Selective catheterization was also necessary for the evidence of the two far-away districts (axillo-femoral).
