Duplexsonografie von Hämodialyseshunts

Key words

arteries - blood vessels - veins - shunts - ultrasound-color doppler

Kernaussagen

• Vor jeder Shuntanlage sind eine klinisch-angiologische Untersuchung und eine FKDS durchzuführen.

• 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.
