Overview

For patients of abdominal angina with symptoms, surgery is the main treatment to relieve the symptoms and prevent intestinal infarction. There is no effective medical therapy exists for this disorder.

Surgery

The most common indication for treatment of abdominal angina is the presence of symptoms related to intestinal ischemia. Patients without symptoms do not constitute an indication for treatment. The main treatment for patients with abdominal angina is surgery.

  • Surgery: The goal of surgery is to relieve the symptoms of abdominal angina and prevent intestinal infarction. Usual types of surgery include thrombectomy (removal of the obstructing lesion) and/or bypass of the obstructed portion of the blood vessel with an endogenous or prosthetic vascular conduit.
  • Endovascular surgery: During this procedure, an aortogram is performed at first. After the narrowed artery is identified, the doctor uses a guide wire across the narrowed portion of the artery under direct fluoroscopy, dilating the narrow portion by a balloon. If residual stenosis is more than 50% of the expected artery luminal, a stent is recommended to place a stent across the narrowed portion of the blood vessel.
  • Open surgery: This kind of surgery is appropriate for patients whose lesions are not amenable to endovascular management. Under general anesthesia, the arteriotomy is performed to the patient to open the artery, then followed by embolectomy and removal of atherosclerotic plaques.
  • Stents have been used in the treatment of abdominal angina.[1][2]
