Reinforcement of Vascular Grafts with Viable Intestinal Segments: Five-Year Follow-Up Study

AMA Arch Surg. 1958;76(4):575-579. doi:10.1001/archsurg.1958.01280220095019

In an experimental study that began in 1947, intestinal segments were used as a means of replacing or reinforcing structures in the thorax and the abdomen.1-4 One phase of this study dealt with the reinforcement or reconstruction of vascular grafts in animals.2,5 Another phase was concerned with an unsuccessful attempt at reconstructing an intima from inert materials—cast gelatin tubes, rolled gelatin tubes, glucose tubes, and dicetylphosphate.

Several animals of a series in which viable intestinal segments were used to reinforce vascular grafts have survived for five years. The procedure used in the reinforcement of these vascular grafts with viable intestinal segments is illustrated in Figure 1 and has been fully described in a previous article.5 Gross and microscopic studies, as well as drug studies, have been made of the reinforced grafts.
