A tiny ultrasound device may be helpful in the treatment of pulmonary embolisms (PEs) - blockages of blood vessels in the lungs, according to a new study conducted at East Jefferson General Hospital in Metairie, US.
In the study, which included 27 patients with PEs who were treated with the ultrasound device, all of the patients survived and they experienced a significant reduction in right heart chamber size.
In addition, the size of each clot was reduced by an average of more than 50%.
In the ultrasound method, the device is inserted through the blood vessels to the site of blockage, where it emits the sound waves that loosens the clot and allow the clot-busting drugs to dissolve it faster.
PE can occur after a clot in another part of the body, dislodges and travels through heart, lodging in a lung artery.
