A comparison of conventional and digital intravenous arteriography in the follow-up of femoro-crural bypass operations.
The value of intravenous arteriography, otherwise known as digital vascular imaging (DVI) in the late postoperative control of femoro-crural bypass operations is determined by comparing its results with those of conventional arteriography. Ten patients with 12 grafts were studied by both methods after a mean postoperative follow-up period of 83.5 months. DVI was 100% accurate in the determination of graft patency. In most patients it provided reliable information regarding the status of the distal anastomosis and the patency of the distal runoff. Since DVI has been proven accurate, has a good patient acceptance, and can be performed as an outpatient procedure, it is preferable to conventional arteriography for the objective documentation of long-term graft patency.
