and microcirculatory perfusion. The right mABP, which reached a nadir of 29 mmHg, also improved gradually until 42 mmHg. While studies have shown no significant differences in mABP between PF and NPF, indexed systemic vascular resistance( SVRi) during aortic cross-clamping was significantly lower with PF [ 14--18, 25 ].
Finally, the pulsatile method for upper body malperfusion remains a concern in its usefulness because NIRO improved, but it does not confirm improving true lumen blood flow by using echo. Therefore, this method is unprecedented, and it is uncertain whether similar results can be achieved. Also, this technique may not work in all instances, this case report is meanttoremindotherstokeepinmindthatPFisanoption we possess as a potential solution in malperfusion cases.
