Does peripheral venous pressure correlate with central venous pressure and mean arterial blood pressure during pheochromocytoma resection?
Peripheral venous pressure closely reflects central venous pressure and changes in venous tone during pheochromocytoma resection.
Peripheral venous pressure may serve as a noninvasive surrogate in pheochromocytoma resection; leaves open whether it can replace central monitoring.
In Brief Venous pressures measured from peripheral venous catheters (PVP) closely estimate the central venous pressure (CVP) in surgical and critically ill patients. CVP is often used to estimate intravascular volume; however, fluctuations of CVP may also be induced by changes in venous tone caused by α-adrenergic catecholamine stimulation. We simultaneously monitored PVP, CVP, and mean arterial blood pressure during resection of pheochromocytoma in a 63-yr-old woman and found excellent correlation between the three pressure variables, suggesting that fluctuations of PVP reflect overall changes in vascular tone. IMPLICATIONS: Both peripheral and central venous pressures reflect changes in venous tone during resection of a pheochromocytoma.

Weingarten et al. (2004) conducted a case report in Pheochromocytoma (n=1). Peripheral venous pressure (PVP) monitoring vs. Central venous pressure (CVP) and mean arterial blood pressure was evaluated on Correlation between PVP, CVP, and mean arterial blood pressure. Peripheral venous pressure showed excellent correlation with central venous pressure and mean arterial blood pressure during pheochromocytoma resection in a 63-year-old woman.
