Had subclavian aneurysm in the right hand. That was evident from a pulsating mass above the right collar bone. Doctor installed a sefl expandable stent in it. After the operation the pulsating mass still exists. The doctor says some portion of the aniurysms is leaking out from the neck of the aniurysms which is causing the pulsating feeling even after the operation. My question is since the major part of the aniurysms has been stent covered is there any chance of the artery getting ruptured ?
