Ten angioscopies with a pressure infusion set resulted in similar visualization times and irrigation volumes as 42 angioscopies
with a specially constructed roller pump. Diagnostic image quality, however, was obtained almost exclusively with the roller
pump. Three examinations were nondiagnostic. Total viewing time per patient was approximately 1 min with the roller pump and
2 min with the pressure infusion system. In the 30 patients examined, angioscopy changed the initially chosen form of therapy
in 5 patients.
