A fine methacrylate ring (not constricting the artery) was placed around
the ramus interventricularis anterior (RIA) of the left coronary artery in
dogs. By means of Falck's histochemical technique an extensive degeneration
of the vasomotor and cardiomotor adrenergic innervation of ventricles was
detected 14 days after the procedure. The innervation of atria remained
intact. The surgical intervention as well as the scarring process (which
compressed the conducting parts of axons composing the perivascular nerves)
induced the degeneration. The results have important implications for
experiments with instrumented arteries.
