In our hands, in vivo segmental vessel length changes up to 5% because of blood pressure: increasing in arterial pressure is associated to decrease in segmental vessel length. Using two piezoelectric crystals sutured on vessel wall and a high fidelity pressure probe, we recorded artery length variat...
