Background.
A necktie may elevate intracranial pressure through compression of venous return.
We hypothesised that a tight necktie would deleteriously alter cerebrovascular reactivity.
Materials and Methods.
A necktie was simulated using bespoke apparatus comprising pneumatic inner-tube with aneroid pressure-gauge.
Using a randomised crossover design, cerebrovascular reactivity was measured with the “pseudo-tie” worn inflated or deflated for 5 minutes (simulating tight/loose necktie resp.).
Reactivity was calculated using breath hold index (BHI) and paired “t” testing used for comparative analysis.
Results.
We enrolled 40 healthy male volunteers.
There was a reduction in cerebrovascular reactivity of 0.23 units with “tight” pseudotie (BHI loose 1.44 (SD 0.48); BHI tight 1.21 (SD 0.38) P<.001).
Conclusion.
Impairment in cerebrovascular reactivity was found with inflated pseudo-tie.
However, mean BHI is still within a range of considered normal.
The situation may differ in patients with vascular risk factors, and confirmatory work is recommended.
