Primary stent implantation for bilateral spontaneous cervical ICA dissections with hypoperfusion after 72 h from onset: a case report

BACKGROUND: Spontaneous cervical internal carotid artery dissection (cICAD) is a common cause of stroke in young adults. Endovascular therapy is an indispensable treatment for cICAD in some cases, but it faces great challenges. CASE PRESENTATION: A bilateral spontaneous cICADs with hypoperfusion-related AIS after 72 h from the onset was presented herein. The patient responded well to primary Solitaire stent detachment at the critical flow-limiting site. CONCLUSIONS: Primary stent implantation at the critical flow-limiting site rather than covering the entire dissection may be a therapeutic option in spontaneous cICAD complicated with cerebral hypoperfusion. The Solitaire stent may be a good choice at the acute and subacute stages of cICAD.
