Endovascular treatment of cervical artery dissection: ten case reports and review of the literature.

PURPOSE: The role of endovascular treatment in cases of cervical artery dissection (CeAD) is debatable. With an increasing number of endovascular therapies such as endovascular recanalization and embolization the number of complications such as iatrogenic dissection is also rising. We report our experience with endovascular stenting in the treatment of patients presenting with CeAD. METHODS: We included all consecutive patients with CeAD (n = 168) treated in our hospital between 2001 and 2010 for our retrospective study. Patients with CeAD were considered eligible for stenting: (1) in iatrogenic dissections and (2) in noniatrogenic dissections if they suffered from recurrent ischemic events despite antithrombotic treatment. RESULTS: During our observation period 10 out of 168 patients presenting with CeAD were selected for stenting. Several types of stents were used. Stenting was technically successful in 8 but unsuccessful in 2 patients with complete arterial occlusion. Stent-related clinically apparent complications occurred in 3 of the 10 patients. All were transient. During a mean follow-up of 47 (±24.8) months none of the patients had new cerebrovascular ischemic events. CONCLUSION: In our patient sample stenting due to dissection is a rare procedure performed in less than 10% of CAD patients. It should be considered as a feasible rescue treatment in cases of impending stroke despite optimal antithrombotic therapy.
