Once embolus is aspirated into cut, it is held with syringe vacuum while catheter and trailing embolus are withdrawn (Reprinted with permission from Greenfield LJ, Mulholland MW, Oldham ICT, Zelenock GB.

6. Fig. 5
Multiple pulmonary emboli extracted by repeated passage of embolectomy catheter into impacted branches of PA. Center embolus is seen to be folded at end (right) where is was captured within cup.

A, It is possible to insert embolectomy catheter percutaneously through large sheath and then manipulate catheter for capture of embolus. B, Most emboli are captured in folded position and when embolus encounters sheath, either portions of it will be sheared off (left) or it will detach to reembolize into PA (right). Sheath also increases risk of air embolism.
