Postpartum cervicocephalic artery dissection.
OBJECTIVE
Cervicocephalic artery dissection (CAD) after childbirth is rare. The objective of this study was to determine differences between postpartum and nonpostpartum CAD.


METHODS
We compared consecutive patients with postpartum CAD with a control group of women with nonpostpartum CAD.


RESULTS
Of 245 patients with CAD, 102 women <50 years (6 with postpartum CAD and 96 with nonpostpartum CAD) were identified. Vascular risk factors and presenting characteristics did not differ significantly between postpartum CAD and nonpostpartum CAD women. By contrast, patients with postpartum CAD had more often coexisting conditions such as reversible cerebral vasoconstriction syndrome (2 of 6 versus 2 of 96; P=0.017), reversible posterior leukoencephalopathy syndrome (2 of 6 versus one of 96; P=0.009), and subarachnoid hemorrhage without signs of intracranial extension of CAD (2 of 6 versus zero of 96; P=0.003).


CONCLUSIONS
CAD and associated conditions should be looked for in women with unusual headache after childbirth.
