Thoracic Endografts Removes Tumors in the Aorta
(Ivanhoe Newswire) -- There is a high risk of complication and death with the surgical removal of chest tumors; it is very challenging and necessitates the support of a heart-lung machine. However, researchers at the University of Toronto have found that placing a stent within the aorta may facilitate the removal of the tumor and eliminate the need for heart-lung bypass.
Endovascular grafts are inserted into blood vessels in the groin, and then threaded through the vasculature until they reach the aorta, where they prop up the vascular wall and keep the lumen open. In the study, five patients with tumors infiltrating the aorta received an aortic endograft 1-9 days prior to tumor resection. After 9 to 62 months, all patients had survived and remained free of disease. There were no endograft-related complications.
