[Control of the patency of coronary-internal mammary artery bypasses by non-selective angiography].
98 successive coronary bypasses using the internal mammary artery were controlled systematically, at an early stage, about the 17th postoperative day, by non selective brachial angiography using a retrograde injection. This control method, simple, quick, reliable and non-aggressive, enables to visualize the internal mammary artery and the bypassed coronary vessel, over its entire length. There were no failure in the control, nor any local or general complication during this examination. The overall patency of such bypasses, evaluated with this method, is 98 p. cent in our series, with however, 12 p. cent of angiographic aspects of a poorly functional bypass. These aspects are related to a slow flow in the by-pass (spindly internal mammary artery, anastomotic stenosis or thin distal bed of the bypassed coronary artery), or to a competitive flow (non significant coronary stenosis). The perfusion of the bypassed coronary, which is not so well studied in the literature, is important to analyze and difficult to evaluate with our technique because of the static views that are used. A similar non-selective angiographic method using a dynamic recording (radio-cinema with dual incidence) is currently being evaluated.
