Yemen i/ËjÉmÉn/, officially known as the Republic of Yemen, is an Arab country in Western Asia, occupying the southwestern to southern end of the Arabian Peninsula. Yemen is the second largest country in the peninsula, occupying 527,970 km2. The coastline stretches for about 2,000 km.
The case described here is unusual, because it concerns a pseudoaneurysm of the common carotid artery (before truncal bifurcation), a rarely observed localization. Moreover, this pathological condition was an unexpected event, being the uncommon result of a minor blunt trauma (whiplash trauma in a car crash).
Although concussion can occur as a result of whiplash, there is a marked difference in the threshold of force required to injure the brain vs. the neck. The lowest threshold to cause brain trauma in animals is about 60 g of force, but the limit of tolerance to whiplash is an acceleraiton of about 14g.
