Die Grundlagen der interventionellen Sonografie

Kernaussagen

• Ultraschallgesteuerte Interventionen können entweder mittels „Freihand”-Technik oder mithilfe einer am Schallkopf angebrachten Nadelführung vorgenommen werden.

• Biopsien werden entweder mit Feinnadeln oder Stanznadeln durchgeführt als Aspirations- oder Stanzbiopsien.

• Ultraschallgesteuerte Interventionen haben ein geringes Mortalitäts- und Komplikationsrisiko.

• Es besteht kein internationaler Konsens hinsichtlich der genauen Laborwerte, bei denen eine Biopsie nicht durchgeführt werden sollte.

Core statements

• Ultrasound guided interventions may be performed either “free-hand” or with a needle guidance attached to the transducer.

• Biopsy is performed with either fine needles or ­coarse needles and may be aspiration biopsies or core biopsies.

• Ultrasound guided intervention has a low mortality risk and low risk of complications.

• There is no international consensus as to the exact values of the laboratory data at which a biopsy should not be performed.
