Introduction: An experimental epidural hematoma model was used to study the relation of ultrasound indices, namely, transcranial color-coded-Doppler (TCCD) derived pulsatility index (PI), optic nerve sheath diameter (ONSD), and pupil constriction velocity (V) which was derived from a consensual sonographic pupillary light reflex (PLR) test with invasive intracranial pressure (ICP) measurements.

Material And Methods: Twenty rabbits participated in the study. An intraparenchymal ICP catheter and a 5F Swan-Ganz catheter (SG) for the hematoma reproduction were used.

We evaluated blood flow changes after experimental free tissue transfer and the potential hemodynamic effect of sildenafil on the free flap. Sixteen swine were used for free transfer of a latissimus dorsi myocutaneous flap to the chest that was anastomosed to the internal mammary vessels, and were randomized into controls and study group. The latter received a single dose of sildenafil, 6 hours following flap revascularization.
