Biopsy with Side-Cutting Coaxial Needle—Knowing the “Cutting Length” and “Throw Length”

Abstract: Image-guided Trucut biopsy is a well-established procedure. The length of the side notch in the stylet is the “cutting length,” which entraps the tissue sample and contributes to the yield. The total distance by which the inner stylet protrudes from the outer cannula with the cutting notch open is the “throw length.” It is inevitably longer than the cutting length does not add to the yield of the sample, but potentially to the complication of the procedure. The authors highlight the importance of knowing this … Show more

“…[ 78 ] Hemorrhage occurrence may thus be time delayed, resolution dependent, brain‐structure specific, or population variable. Side‐cutting needle biopsy collection is similar in dimensions (≈1.5 mm diameter [ 135 ] ) to current clinical neural stimulation technology (e.g., deep brain stimulation (DBS) electrodes). [ 136 ] This suggests that brain hemorrhage induced by or following surgical device insertion can be suspected, and in most cases is asymptomatic.…”

“…El conocimiento de la anatomía local, la correcta ejecución de la planificación y la experiencia del operador se asocian a resultados favorables 7 . El conocimiento de las agujas y su alcance también tiene sus consecuencias directas en estas prácticas 15,16 . Por el contrario, el déficit en alguno de los puntos mencionados puede tener un efecto deletéreo inmediato en la salud del paciente y un impacto negativo en los resultados del procedimiento 7,17 .…”

“…Por el contrario, el déficit en alguno de los puntos mencionados puede tener un efecto deletéreo inmediato en la salud del paciente y un impacto negativo en los resultados del procedimiento 7,17 . Dentro de la planificación de la intervención debería considerarse la potencial lesión inadvertida de órganos vitales adyacentes 15 . Por tal motivo, los accesos deben planificarse evitando apuntar hacia a estas estructuras (de ser posible) 18,19 .…”

“…It acts as a physical barrier to secure the tissue sample within the notch, thereby preventing its dislodgment during the needle's withdrawal. Moreover, the Dead Space Length can influence the needle's trajectory, [1] thereby affecting the risk of complications, particularly when the target lesion is in close proximity to vital structures.…”
