BACKGROUND AND PURPOSE: The value of long-term serial imaging of dissecting pseudoaneurysm (dPSA) is poorly characterized. This study investigated the long-term radiographic evolution of dPSA.
METHODS: We performed a query in our institutional craniocervical artery dissection registry to identify cases with spontaneous dPSA who had at least one year of follow-up with serial angiographic imaging. We performed Wilcoxon rank-sum pairwise comparison test to determine if there was a significant change in the aneurysm size over time.
RESULTS: This observational cohort study included 76 patients (46 females; 64 dPSA in the internal carotid artery [ICA] and 12 in the vertebral artery [VA]) with a median age of 49.5 years (range 24-77). The initial median dPSA size was 8 mm (interquantile range(iqr) = 5.88-11mm), and the final median dPSA size was 7 mm (iqr = 4-11 mm). Most patients had either no change or reduction in dPSA size in the serial follow-up, with no significant change over time. All the patients had favorable outcomes at the last follow-up, and most patients were symptom-free from dPSA (92 %). Two patients (2.6%) experienced recurrent ischemic strokes in the same territory as the initial ischemic stroke without any change in dPSA size.
CONCLUSION: Further serial scans for dPSA after one year may be deferred in the absence of interim clinical symptoms as most dPSA either remains stable or decreases in size. Recurrent stroke, although a rare event, was not associated with an increase in dPSA size.
