Can Ultrasound be used to treat pseudoaneurysms?
There are two main nonsurgical means of treating a pseudoaneurysm, both based on US. Ultrasound-guided direct transcutaneous pressure can be held over the neck of the pseudoaneurysm to thrombose and close off the neck. However, this can be a time-consuming and painful method with variable success rates. A more popular method now used is ultrasound-guided direct injection of thrombin into the pseudoaneurysm with a success rate of up to 90%.
