Abstract
Experiments were performed in 18 dogs to evaluate the character and time course of
arterial injury caused by balloon embolectomy catheters. Injury was correlated with
balloon-artery shear forces. Shear forces were regulated intraoperatively. Thirty
gram force caused no injury in 14 specimens. Sixty gram force stripped the intimal
endothelium in two of four specimens examined at 2 days. Repair consisted of myointimal
hypercellularity with return to normal one-cell thickness within 28 days. Ninety and
120 gram force stripped the intimal endothelium in 32 specimens with no medial injury.
Repair again consisted of myointimal proliferation, which returned to normal in most
vessels at 28 days. All vessels appeared normal at 6 months. This indicates that balloon
embolectomy catheters can be a safe operative tool provided excessive shear forces
are not imposed. This is quite feasible, for usual embolectomies were found to require
about 60 gm shear force. Two hundred gram initial force caused intimal injury and
fracturing of the internal elastic lamina, with the latter injury persisting even
after 6 months.
