Intraoperative arteriography during femoral-popliteal bypass.
Minor technical errors may jeopardize the patency of femoral-popliteal bypass grafts. In an attempt to detect such errors, intraoperative arteriography has been routinely employed. It allows immediate recognition and correction of the most common abnormal findings: intraluminal debris, intimal dissection, distal thrombosis, arterial spasm, and kinking of the graft.
