Introduction/Purpose The cerebral venous sinus became frequently evaluated for various diseases, including idiopathic intracranial hypertension. Venous access via an upper extremity has several merits, including early ambulation and saving the pelvic area from radiation. We have performed outpatient-based cerebral venography and manometry as well as transfemoral cerebral angiography at our institution. We present the results of outpatient-based cerebral venography and manometry via the antecubital vein.
Materials and Methods We retrospectively reviewed the neurointervention database at our institution from January 2020 to February 2023. We included outpatients undergoing cerebral venography and manometry via the antecubital vein. We reviewed demographics, cases converting to femoral venous access, technical success, and complications, including puncture site problems. Technical success was defined as obtaining cerebral venography in the venous sinus upstream to the stenotic lesion and measuring venous sinus pressure.
Results Eleven consecutive outpatients underwent cerebral venography and manometry using a 4-French diagnostic catheter via the antecubital vein. A microcatheter was used in ten cases, and one procedure could be finished only using a 4-French diagnostic catheter. Female patients were seven of them. The mean age and BMI were 42.0 years old and 25.0, respectively. Patients’ diagnoses were idiopathic intracranial hypertension in eight cases and pulsatile tinnitus in three cases. Two cases were converted to femoral venous access due to severe arm pain and an undetectable superficial vein under ultrasonography. All procedures were technically successful. There were no complications, including puncture site problems.
Conclusion We think that performing outpatient-based cerebral venography and manometry via the antecubital vein is safe and feasible. Since there were cases converting to a transfemoral venous approach, further research is needed to determine which patients would be appropriate for attempting femoral venous access first.
