Abstract
Arteriotomy/intimectomy and venotomy/intimectomy were performed in the ears of 43 rabbits. Twenty were treated with iloprost given as intravenous doses of 10 micrograms/kg body weight (bw) administered shortly before reperfusion followed by hourly infusions (3 micrograms/kg b w) until 12 hrs after reperfusion. At reperfusion venous and arterial bleeding times were noted. Patency was determined at 15-min intervals until 2 hrs after reperfusion and at 1 and 2 weeks postoperatively. As controls, 23 rabbits were given a single infusion of saline. Compared to controls, iloprost significantly prolonged arterial and venous bleeding times and significantly improved patency 2 hrs after reperfusion. One and two weeks later, however, virtually all vessels were occluded. Administered in this fashion, iloprost does not improve long-term patency in highly traumatized small veins and arteries.
