Key result
Bilateral carotid occlusion resulted in a mean change in hepatic blood volume of less than 2%, with no significant difference between innervated and denervated livers.
Bilateral carotid occlusion does not cause significant changes in hepatic blood volume or capacitance vessel responses in anesthetized cats.

Bilateral carotid occlusion elicits negligible hepatic blood volume change in anesthetized cats; leaves open baroreflex control of splanchnic capacitance in conscious or other species models.
Hepatic volume was recorded by a plethysmographic technique in cats anesthetized with pentobarbital; the hepatic artery and portal vein remained intact. The mean change in hepatic blood volume during bilateral carotid occlusion was less than 2% and there was no significant difference between responses in innervated and denervated livers. These results, together with other reports in the literature, support the conclusion that capacitance vessel responses, a redistribution of blood volume, a change in cardiac output, and release of catecholamines from the adrenal medullae do not occur in arterial baroreceptor reflex responses.

Lautt et al. (1972) studied this question. Bilateral carotid occlusion vs. Innervated vs denervated livers was evaluated on Mean change in hepatic blood volume. Bilateral carotid occlusion resulted in a mean change in hepatic blood volume of less than 2%, with no significant difference between innervated and denervated livers.
