Thrombus in the Superior Sagittal Sinus Was Successfully Aspirated by Coaxial Catheter Technique: A Technical Case Report

抄録

Objective: We report a case of superior sagittal sinus thrombosis, where aspiration of the thrombus using a 6 Fr coaxial catheter (CC) resulted in prompt and complete recanalization.

Case Presentation: A 69-year-old female was brought to our hospital by ambulance due to headache and left hemiparesis. MRI images revealed superior sagittal sinus thrombosis. Endovascular treatment was performed in addition to anticoagulant therapy to prevent clinical deterioration and to achieve an early improvement. Unfortunately, neither intrasinus chemical thrombolysis nor mechanical thrombectomy with a balloon led to recanalization. Therefore, we used a CC, 6 Fr Cerulean catheter DD6 (Medikit co. ltd., Tokyo, Japan), as an aspiration catheter, which resulted in prompt and complete recanalization. Consequently, her symptoms disappeared shortly thereafter.

Conclusion: As the endovascular treatment of venous sinus thrombosis, thrombus aspiration through a 6 Fr CC may be an effective option.
