What treatment option is typically used for an unsuccessful angioplasty in Type 1 endoleaks?

In the management of Type 1 endoleaks, particularly when there has been an unsuccessful angioplasty, the typical approach is to utilize a bare metal stent (BMS). Type 1 endoleaks occur when there is a failure of the seal at the graft's proximal or distal ends, which allows blood to flow outside the graft and potentially re-enter the aneurysm sac. In cases where attempt to resolve these leaks via angioplasty does not succeed, placing a bare metal stent can effectively reinforce the seal and provide additional support to the affected area of the graft.

The use of a bare metal stent is ideal in this context as it helps to maintain the graft's position and is effective in closing gaps that cause the endoleak, allowing for improved flow dynamics and minimizing the risk of aneurysm rupture. This intervention is less invasive than other options like open surgical repair, making it a preferred treatment unless the situation necessitates more aggressive measures.

Employing a second stent graft can overcomplicate the procedure and might not effectively resolve the endoleak, as it may also cause new leaks or contribute to other complications. Similarly, while coils can be effective in managing certain types of endoleaks, they are not typically the first line
