¿Es la arteriografía preoperatoria un método tan infalible como se cree?

The important degree of interobserver variability seen in the evaluation of below-the-knee segments must be taken into account when other methods of diagnosis are compared to preoperative angiography. In this work we question its reliability, underline the need for intraoperative angiographic studies and call attention to an important bias in the interpretation of publications when attempts are made to compare this preoperative test with other non-invasive methods.
