Q: What is Rheolytic embolectomy in pulmonary embolism (PE)?
Answer: Data is very limited and efficacy is not fully established but rheolytic embolectomy consists of injecting pressurized saline through the catheter's distal tip while macerated thrombus is being aspirated through a catheter port.
This technique should be used in selected cases as it requires a venous cut-down for the insertion of the catheter. It is also suggested that the release of adenosine from disrupted platelets can lead to bradycardia, vasospasm, and hypoxia, and red blood cell fragmentation can result in hemoglobinuria. It is suggested to utilize this route when systemic thrombolysis fails in PE.
