Intrarachidial Misplacement of a Venous Stent for Iliofemoral Deep Vein Thrombosis.

Introduction: Complications due to venous thrombectomy and iliofemoral stenting in a patient with May-Thurner syndrome are reported.

Report: The patient presented with a third episode of deep vein thrombosis (DVT). A computed tomography (CT) scan confirmed the clinical suspicion of left iliofemoral vein thrombosis. After thrombectomy and stenting, the patient complained of left foot paralysis. CT showed the misplaced stent to be in the intrarachidial space. Surgical removal of the stent and new endovascular stenting resulted in complete recovery.

Discussion: This is the first description of this kind of complication after stenting of the left iliofemoral vein. Peri-operative Xray appeared to confirm correct placement of the stent via bilateral femoral venous access. Is a profile control image necessary in patients with an important collateral venous network including large veins?
