From: Mechanical thrombectomy for pulmonary embolism in patients with patent foramen Ovale
An example of MT in a patient with a clot at the access site, and why there is a concern for paradoxical embolization if the patient has PFO. a Initial pulmonary angiogram through the Inari catheter (arrows) shows multiple large filling defects in the left pulmonary artery. The catheter crosses the right atrium, tricuspid valve and right ventricle. b Angiogram through a vascular sheath in the right common femoral vein (long white arrow) show large clot (short white arrow) at the tip of the Inari catheter. There is a risk of paradoxical embolization if patient has PFO in case of release of clot from the tip of catheter during catheter pull back. c Final angiogram shows almost complete removal of the clots. d A sample of thrombus was removed during mechanical thrombectomy
