Arterial Reconstruction (Aortic, Mesenteric, Renal and Peripheral) is a common procedure for the treatment of arterial aneurysm, a condition that causes clots to form and block the normal blood flow. The goal of this procedure is to redirect the blood flow in the artery or relieve the compression of a nearby nerve or vein that can result in pain, numbness or swelling. A few days before the procedure, tests may be performed to ensure that it is safe to proceed with the surgery. Patients may need to discontinue certain medications before the procedure. An arterial reconstruction will be performed under general anesthesia in a hospital setting and usually lasts between three and five hours. The procedure may require a minimum hospital stay of seven to 10 days, but your doctor will discuss your hospital stay prior to your procedure.
