A technical tip for total laparoscopic type II endoleak repair.

Area of Science:

• Vascular Surgery
• Minimally Invasive Procedures
• Endovascular Repair

Background:

• Type II endoleaks following endovascular aneurysm repair (EVAR) can necessitate intervention.
• Laparoscopic repair is a minimally invasive option, but controlling feeding arteries like lumbar and median sacral arteries is technically demanding due to surrounding inflammation.
• Dense inflammatory tissue around the aorta complicates direct dissection of the aneurysm sac during laparoscopic procedures.

Purpose of the Study:

• To describe a simplified technical approach for laparoscopic repair of type II endoleaks.
• To present a method that facilitates control of lumbar and median sacral arteries during laparoscopic aortic surgery.
• To demonstrate a technique that avoids direct, close dissection of the aneurysm sac.

Main Methods:

• A transperitoneal laparoscopic approach is utilized, standard in laparoscopic aortic surgery.
• The aneurysm sac is retracted to the right, exposing the plane of the anterior longitudinal ligament.
• Lumbar and median sacral arteries are identified and ligated along the anterior spine without dissecting the aneurysm sac itself.

Main Results:

• The described technique provides direct exposure of the target arteries.
• Methodical dissection and ligation of lumbar and median sacral arteries were achieved.
• The approach successfully simplified the laparoscopic repair of type II endoleaks in the authors' experience.

Conclusions:

• This technical tip offers a feasible and simplified method for laparoscopic type II endoleak repair.
• Avoiding close dissection of the aneurysm sac enhances the safety and efficiency of the procedure.
• The technique facilitates improved access and control of critical arteries during laparoscopic EVAR complication management.
