CONTROVERSIES

15. Is there an advantage to surgical revascularization with all arterial conduits?

Show answer
The logical extension of the observation that an internal mammary artery has superior patency to a saphenous vein has sparked an interest in total arterial revascularization. Instead of using saphenous veins as bypass conduits, some surgeons also use the right internal mammary artery, the gastroepiploic artery, and the radial artery as bypass conduits instead of vein. Convincing data suggest a survival benefit as well as freedom from angina when the LIM artery is used as a conduit. The data supporting total arterial revascularization are much less clear.

The lifetime risk for duodenal ulcer is about 1 in 14. It usually occurs between ages 20 and 60 years, with peak incidence in the fourth decade of life. It is more common in males. Hemorrhage is the most common cause of hospital admission. The annual number of deaths in the United States is about 10,000 deaths caused by duodenal ulcers.
