Endograft Protocol

An endograft, or stent, is a tube consisting of a fabric-covered wire mesh used to repair an aneurysm, which is a weakened section of blood vessel. The stent is typically inserted through the groin.

History

• The first time an endograft was used to repair the aorta -- the major artery from the heart -- was in 1991, according to the Walker Heart Institute in Fayetteville, Arkansas. The stent was introduced into the femoral artery at the groin and pushed through the vessel to the aneurysm.

Patient Preparation

• According to Central Illinois Radiological Associates, patient preparation for an endograft, following the history and physical exam, consists of a blood draw, EKG to assess heart function, x-rays of the chest and aneurysm and insertion of an IV catheter for anesthesia. The patient's groin and abdomen are then cleaned and disinfected.

Stent Insertion

• The surgeon makes an incision in the groin, inserts the stent into the femoral artery and injects a dye that allows the arteries to be visualized by x-ray. This allows proper placement and release of the stent. Scans are taken to ensure proper blood flow through the stent. The patient remains under observation for several days before release from the hospital.
