Effect of suture technique on arterial anastomotic compliance

To determine the immediate effect of running and interrupted suture on
anastomotic compliance, catheters were positioned in both femoral arteries
of ten dogs for pressure measurement and introduction of an electromagnetic
rheoangiometry loop probe. Changes in the area of the loop allowed
simultaneous determination of the static and pulsatile internal diameter of
the vessel when the loop was in an externally induced magnetic field. After
dynamic diameter compliance (Cd) of the undisturbed femoral arteries was
obtained, they were exposed, stripped of their adventitia, and divided.
They were subsequently anastomosed with 6-0 polypropylene suture using a
running anastomosis for one femoral artery and an interrupted anastomosis
for the other; Cd was then measured 1 cm proximal to the anastomoses, at
the anastomoses, and 1 cm distal to the anastomoses. The Cd significantly
decreased with both running and interrupted anastomoses; running
anastomoses showed significantly greater decrease in compliance than did
interrupted.
