[Significance of digital subtraction angiography (DSA) in the evaluation of reconstructive vascular interventions].

Abstract

The author examined 160 patients by means of digital subtraction angiography (DSA) after reconstructive vascular surgery. The checkup aimed to controlling the functional capacity of arterial and venous bypasses, of thrombal endarterectomy (TEA) and percutaneous transluminal angioplasty (PTA). The image quality of the examinations was good or very good in 138 cases and satisfactory in 19 cases in respect of the questions to be solved. In 3 cases, no information of diagnostic value was obtained. Vascular wall irregularities, stenoses, occlusions, dissections and aneurysms could be assessed with satisfactory display of anatomic details. Evidently DSA yielded a higher percentage of better results in the assessment of reconstructive vascular surgery than was obtained by pretherapeutic diagnosis in the region of the vessels, head, trunk and body periphery.
