“…Marik et al ( 25 ) used carotid artery Doppler ultrasound to assess hemodynamically unstable patients and observe a significant increase in the diameter of the CCA in the fluid responders. Bapat et al ( 26 ) reported an increase in the diameter of the brachial artery in response to volume loading by a passive leg raising (PLR) maneuver.…”

Objectives: The current study aimed to find the relation between the changes in the common carotid artery (CCA) diameter and the central venous pressure (CVP) in response to a fluid challenge in spontaneously breathing adult patients. Methods: This study included 65 adult patients aged 20 - 60 years who were admitted to the surgical ICU. The CCA diameter and CVP were measured before and after fluid challenge, and the percentage of increase in the CCA diameter and CVP were calculated. The correlation was assessed between changes in the CVP and CCA diameter. Results: The CCA diameter before fluid administration had a significant strong positive correlation to the CVP (r = 0.8, P value < 0.001); the increase in the CCA diameter after fluid administration had a significant moderate positive correlation with the increase in the CVP (r = 0.4, P value < 0.001). The percentage of increase in CCA diameters was positively correlated to the percentage of increase in CVP (r = 0.589, P value = 0.001) following fluid administration. However, the Receiver Operating Characteristic (ROC) analysis was an invalid test (area under curve 0.513, P value = 0.885). Conclusions: After major surgeries, the change in the CCA diameter was positively correlated with the change in the CVP values in response to fluid administration in the spontaneously breathing adult patients, but the cut-off limit cannot be reached.

“…PLR, as utilized by Marik et al, as well as intravascular volume expansion both reduce PPV in fluid demanding patients (Geerts et al 2011 ). Furthermore, it has been shown that the diameter of the brachial artery increases in response to a PLR maneuver (Bapat et al 2013 ; London et al 1990 ). This ‘flow mediated dilation’ is described to be caused by endothelial shear stress, leading to increased NO syntheses as well as a reduction of endothelin secretion (Bruno et al 2014 ; Morawietz et al 2000 ; Lüscher and Barton 1997 ).…”

BackgroundIn case of intravascular fluid depletion, large veins react to volume expansion with dilation. Little is known about the reaction of arterial vessels. We herein report on the effect of a standardized fluid bolus on the diameter of the common carotid artery (CCA) and its association with hemodynamic parameters, assessed in 20 mechanically ventilated patients after cardiac surgery. CCA was visualized using ultrasound, and the percentage increase in diastolic diameter was calculated by measuring before and after administration of crystalloid infusion solution. Invasive arterial blood pressure and pulse pressure variation (PPV) were assessed in parallel.ResultsMedian diastolic CCA diameter was 6.2 (Q1–Q3: 5.4–7.1) mm, and it significantly increased to 6.7 (5.8–7.3) mm upon fluid administration [5.0 (1.9–10.5) % increase]. Mean arterial blood (MAP) pressure likewise increased from 68 (70–73) to 85 (71–100) mmHg, whereas PPV was significantly reduced from 17.6 (16.8–23.9) to 13.2 (6.7–18.1) %. There was a significant association between the change in CCA diameter and the hemodynamic response (delta-MAP: r = 0.53, delta-PPV: r = 0.56; p < 0.05). Furthermore, carotid diameter measured before volume expansion significantly correlated with the delta-PPV upon fluid administration (r = −0.5; p = 0.02).ConclusionsDiameter of the CCA increases in response to intravascular volume expansion. Additional studies on the interplay between carotid geometry and intravascular fluid status are necessary.

“…CBF and tissue oxygenation measurements play an important role in evaluating various conditions such as vasospasm, ischemia, injury and recovery processes and cutaneous implant function [1,2]. The ability to monitor non-invasively changes in the skin microcirculation level leads to improvements both in diagnosis and treatment of patients [3][4][5][6][7].…”
