[Nonsurgical pulmonary embolectomy using catheterization]

Deoppilation of the pulmonary arteries by catheterization is infrequently used in severe pulmonary embolism. This technique can only be contemplated when conventional measures, such as injection of fibrinolytic agents or surgical removal of the emboli, cannot be applied. The catheter is introduced under local anaesthesia through the femoral vein or the internal jugular vein, and the emboli are aspirated by exerting a strong depression at the tip of the catheter. Satisfactory results can only be expected in cases with very recent (less than 72 hours), totally occlusive and proximal embolism. Three out of the authors' 6 attempts have been successful.
