Color Doppler ultrasonography imaging to guide transluminal angioplasty of venous stenosis

摘要

Color Doppler ultrasonography imaging to guide transluminal angioplasty of venous stenosis.BackgroundThe objective of access surveillance is the early recognition of dysfunction in order to be able to correct the stenosis by angioplasty or surgery before access thrombosis occurs. The advent of color Doppler imaging has enabled studies of color Doppler ultrasonography (CDU) for the guidance of percutaneous transluminal angioplasty (PTA). The aim of the present study was to investigate whether color Doppler imaging alone can be safely and effectively used to diagnose vascular graft access stenoses and guide subsequent PTA.
