TLDR Botulinum toxin type A may widen certain arteries, but more research is needed.
This preliminary study on 5 patients found that botulinum toxin type A (BoNT-A) significantly increased the diameter of the supratrochlear artery, suggesting its potential for vasodilation and possible benefits in treating ischemic conditions. However, arterial velocity did not change significantly. The study emphasizes the need for larger studies to confirm these findings and investigate BoNT-A's effects on other vascular areas.
