Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
A key consideration for the surgery is whether or not to preserve the vascularization of the variant kidney. Preserving them can be challenging, but removing them can lead to a significant reduction in renal volume and subsequent loss of function. In open surgery repair, it is recommended to reanastomose as many arteries as possible to the prosthesis, even though this introduces additional technical challenges, especially in emergency situations. Computed Tomography Angiography (CTA) is the best diagnostic test for performing a preoperative vascular assessment.
The purpose of the present study is to develop a semi-automated model on preoperative CCTA to measure the volume of parenchyma perfused by each artery to determine whether or not these should be preserved. The model will be validated on post-surgical CCTA in patients with HK treated for AAA.
Customized use of this tool could be a valuable method in surgical decision making, determining which arteries can be made safe during surgery and addressing a rare but complex clinical need.
