Die präoperative FKDS erhöht die Rate funktionsfähiger Hämodialyseshunts. Die Shuntreifung wird klinisch und mittels FKDS überwacht. Wichtige Komplikationen im Verlauf, welche die FKDS diagnostizieren kann, sind der akute Shuntverschluss, arterielle und venöse Stenosierungen, Steal-Phänomene sowie echte und falsche Aneurysmata. Key Statements A clincial-angiological examination and a CCDS should be performed prior to placement of every access. Preoperative CCDS increases the rate of functioning hemodialysis shunts. Shunt maturation should be monitored clinically and by CCDS. Important complications in the course that can be diagnosed by CCDS are acute shunt occlusion, development of arterial and venous stenoses, steal phenomena, as well as true and false aneurysms.
