Key result
Low and ultra-low-dose ASA improve patency and reduce platelet aggregation in a rabbit trauma model.
Why the study?
The effects of low and ultra low oral doses of acetylsalicylic acid on bleeding, platelet function, and vascular patency after severe vascular trauma were investigated.

Does oral acetylsalicylic acid at low and ultra-low doses improve patency and affect bleeding/platelet parameters in a rabbit model of microvascular surgery?
Low and ultra-low doses of oral acetylsalicylic acid improve vascular patency and reduce thromboxane production in a rabbit model of microvascular trauma.
Salemark et al. (1991) studied severe vascular trauma (arteriotomy/intimectomy). Acetylsalicylic acid (ASA) vs. controls was evaluated on patency, bleeding times, platelet accumulation, thromboxane production, and platelet aggregation. Low and ultra-low oral doses of acetylsalicylic acid increased patency and bleeding times, reduced thromboxane production, and decreased platelet aggregability in a rabbit model of vascular trauma.
