Effect of perivascular sympathectomy on distal blood flow in the rabbit forepaw. A dynamic isotope experiment with Tc99m.
Perivascular sympathectomy, used for treating patients suffering from vasospastic disorders of the hand, is believed to cause an increase in the distal blood flow. Its effects were examined here by performing the operation on the metacarpal arteries of the left forepaw of ten New Zealand White rabbits, the right forepaw serving as a control. Blood flow was measured by Tc99m radionuclide angiography five days before the operation and three days and two and a half weeks after it. There was no statistically significant postoperative increase in blood flow in the distal parts, so that it may be concluded that at least in this experimental model, the distal sympathectomy did not have any such effect.
