Family history may flag higher recurrence risk after cervical artery dissection; hypothesis-generating and should not yet change practice.
Does a family history of arterial dissection increase the risk of recurrent dissection in patients with spontaneous cervical artery dissections?
A family history of arterial dissection is a significant risk factor for recurrent dissection in patients with spontaneous cervical artery dissections, increasing the relative risk by over six-fold.
Schievink et al. (1996) studied this question.
