[Value of intravenous digital subtraction angiography (DSA) for the assessment of surgical blood vessel reconstruction]

Abstract

Intravenous digital subtraction angiography (DSA) was obtained in 55 cases after reconstructive procedures of the carotid arteries, the pelvic and lower limb arteries. In 48 cases (87%) the studies were of technically satisfactory or good quality. On DSA 32 vascular reconstructions were normal and 16 had typical complications like occlusions, stenoses, aneurysms and insufficient run-off. -Experience indicates that the spatial resolution of DSA is adequate for clinical purposes such as determining graft patency or the presence of postoperative complications. Because DSA is less invasive than catheter angiography, postoperative evaluation of patients having undergone peripheral surgical revascularization should start with DSA.
