|Extracorporal shock wave lithotrypsy (ESWL)|
Big as well as small stones
can be fragmented by ESWL before
extraction. The example shows
a 7 mm calculus in the left
hepatic bile duct adhering
tightly to the ductular
wall. Neither an extraction
device nor a guide wire could
pass the concrement.
Move the mouse´s arrow onto the figure to outline the stone.
|Extracorporal shock wave lithotripsy achieved a fragmentation of the stone. The fragments show as filling defects behind the target crosslines. Lavage with physiologic saline washes the debris out of the hepatic duct.|
