Key result
Transcatheter endovascular stenting of infrarenal abdominal aortic aneurysms is a less traumatic procedure associated with a shorter hospital stay than conservative surgery.
Transcatheter endovascular stenting provides a minimally invasive alternative to major surgery for infrarenal AAAs, with ultrasonography serving as an effective noninvasive modality for post-procedure follow-up.
Endovascular stenting may reduce trauma and stay for infrarenal AAA; leaves open need for randomized durability data and ultrasound surveillance validation.
Until recently, the repair of an abdominal aortic aneurysm (AAA) required major surgery. Recently, the transcatheter technique has allowed minimally invasive endovascular stenting of infrarenal AAAs. This procedure is less traumatic and is associated with a shorter hospital stay than conservative surgery. With the stent placement, the effective aortic lumen diameter decreases and the aneurysmal space is excluded from the circulation. Ultrasonographic studies have allowed imaging of the abdominal aorta, its main branches, and the endovascular stent. The aortic blood flow after the repair is ideally limited to the stent lumen. Follow-up studies have permitted reevaluation of the aorta and the stent, with special emphasis on the aortic expansion and blood flow within the excluded space. These studies have correlated well with other imaging techniques such as intravascular ultrasound, computed tomography scanning, and aortography.

Kronzon et al. (1999) conducted a review in Abdominal aortic aneurysm (AAA). Transcatheter endovascular stenting vs. Conservative surgery was evaluated. Transcatheter endovascular stenting of infrarenal abdominal aortic aneurysms is a less traumatic procedure associated with a shorter hospital stay than conservative surgery.
