CESA alternative for aortic aneurysm

A U.S. surgeon says patients at high risk to have traditional aortic aneurysm surgery may be helped by a new treatment technique.

Dr. William Quinones-Baldrich of the University of California, Los Angeles' David Geffen School of Medicine describes the good outcomes for combined endovascular and surgical approach in the first 20 of these high-risk patients treated.

The report was published in the Journal of Vascular Surgery.

Quinones-Baldrich explains an aneurysm occurs when blood flow causes part of an aortic artery wall weakened due to age and arterial disease to stretch out like a water balloon.

Due to the tricky position of some aortic aneurysms or the frailty of some patients, not everyone is a candidate for standard surgery to treat a dangerous aneurysm, Quinones-Baldrich said in a statement. We hope this technique may offer patients with these complex aneurysms another option.

For CESA, surgeons access vital arteries stemming from the aorta via an incision in the abdomen and perform bypasses.

Rerouting blood flow to originate from an area of the aorta not affected by the aneurysm allows us to eventually exclude circulation to the aneurysm in the second procedure by employing a tiny device called an endograft, Quinones-Baldrich said.

The endograft is inserted later via the femoral artery through a small incision in the groin.
