AI Article Synopsis
- The study introduces "System-F," a device designed to effectively deliver vascular plugs to aortic side branches during endovascular aneurysm repair (EVAR).
- It features a combination of specialized sheaths and a guidewire that allows for multidimensional movement, facilitating precise placement of vascular plugs in various arteries.
- The results showed no occurrences of type II endoleak in the 7 cases treated, suggesting that System-F could enhance pre-EVAR embolization strategies and improve clinical outcomes.
Article Abstract
Purpose: This study aimed to illustrate the utility of our original system to deliver vascular plugs into aortic side branches during endovascular aneurysm repair (EVAR).
Technique: Our device, which we named "System-F," consists of a 14 Fr sheath, a 12 Fr long sheath with a side hole, a stiff guidewire as a shaft, and a parallelly-inserted delivery catheter navigated through the side hole into the aneurysm sac. Vertical motion and horizontal rotation of the side hole allow multidimensional movement of the delivery catheter within the aneurysm. This system was applied in 7 cases undergoing EVAR; 4 inferior mesenteric arteries and 14 lumbar arteries were embolized using vascular plugs. Type II endoleak (T2EL) was not observed in the follow-up survey of any case. Conclusion: The applicability of System-F for vascular plug placement in the side branches of abdominal aortic aneurysms has the potential to achieve high delivery capability and be widely applied for the prevention of T2EL.
Clinical Impact: System-F has potential to change the strategies of pre-EVAR embolization.
