Key result
Percutaneous balloon catheters enable continuous aortic clamping, potentially allowing EVAR during circulatory collapse.
Why the study?
Does transfemoral balloon occlusion of the aorta allow for endovascular aneurysm repair in patients with ruptured abdominal aortic aneurysms and circulatory collapse?
Does transfemoral balloon occlusion of the aorta allow for endovascular aneurysm repair in patients with ruptured abdominal aortic aneurysms and circulatory collapse?
Transfemoral balloon occlusion of the suprarenal aorta is a feasible technique to maintain aortic clamping during EVAR in patients with ruptured AAA and circulatory collapse.

May enable EVAR in ruptured AAA with circulatory collapse; leaves open need for prospective trials before adoption.
PURPOSE: To describe a technique of aortic clamping during endovascular aneurysm repair (EVAR) in patients with ruptured abdominal aortic aneurysms (AAA) and circulatory collapse. TECHNIQUE: A balloon catheter is inserted percutaneously from the femoral artery and inflated in the suprarenal aorta. An introducer sheath must support the balloon. The stent-graft is passed from the contralateral groin and deployed beneath the balloon. The sheath makes it possible to retrieve the balloon after the endograft has been deployed. Carbon dioxide facilitates angiography while the aortic blood flow is arrested. CONCLUSIONS: The aortic stent-graft can be deployed while the aorta is continuously "clamped" from a transfemoral approach. This may allow EVAR in patients with circulatory collapse due to aneurysm rupture.

Malina et al. (2005) studied Ruptured abdominal aortic aneurysms (AAA) and circulatory collapse. Balloon occlusion of the aorta during endovascular aneurysm repair (EVAR) was evaluated. A balloon catheter inserted percutaneously can continuously clamp the aorta during endovascular aneurysm repair, potentially allowing EVAR in patients with circulatory collapse.
