Fig 5. The 40-mm thrombus (]) is initially mobilized within the carrying vessel (A) and partially compressed sideways to the microcatheter (B). C, The thrombus enters the balloon catheter (open arrow); compression of the thrombus causes the distal part to stick at the tip of the balloon catheter. The thrombus is elongated (D) and finally fractures with consequent thromboembolization (
) into other major vessels (E). A major potion of the thrombus is retrieved to the balloon catheter.
