Surgical revascularization may be used to treat mesenteric ischemia in individuals who have the chronic form of the condition. Revascularization means the restoration of normal blood flow to the area of concern. A mesenteric artery bypass is a procedure in which an alternate route is constructed for oxygenated blood to flow from the aorta to the mesenteric artery. This alternative route allows the blood to bypass the part of the mesenteric artery that has become blocked or narrowed. The alternate route may be constructed using one of the patient's existing veins, or it is made with lab-created prosthetic material.
Another method of surgical revascularization is called balloon angioplasty and stenting. This minimally invasive procedure opens the obstructed mesenteric artery to restore blood flow to the intestines. During angioplasty and stenting, a catheter or small hollow tube is threaded from an incision in the groin to the affected mesenteric artery. Once the catheter is in place, a balloon is passed through it into the mesenteric artery. The balloon is then inflated to widen the interior diameter of the affected artery. A mesh tube or stent is then used to hold the artery open and restore adequate blood flow.
