The Relation Between Common Carotid Artery Diameter and Central Venous Pressure for Assessment of Intravascular Fluid Status After Major Surgeries: An Observational Study

2019-07-16 10:38:22 | BioPortfolio


Recently, bedside ultrasound has become an important tool for the simple and non-invasive hemodynamic assessment of critically ill patients. This applies not only to echocardiography but also to ultrasound of large extra-thoracic veins. The sonography can provide real time assessment of the vascular system and hemodynamic status at the bedside.

To our knowledge, there is one report about the association between sonographically assessed carotid artery diameter and intravascular volume, which raised recommendation for further studies including the interplay between carotid geometry and intravascular fluid status.

Aim of the study:

The aim of this work is to evaluate the accuracy of noninvasive techniques for assessment of intravascular volume status by Sonographic assessment of both the common carotid artery diameter (CCA) and the central venous pressure (CVP) in response to a bolus of crystalloid solution infusion and to find the correlation between CCA diameter and CVP as the primary outcome in adults patients after major surgeries who needs close assessment and maintenance of the intravascular volume status.

Medical and Biotech [MESH] Definitions

The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (CAROTID ARTERY, EXTERNAL) and internal (CAROTID ARTERY, INTERNAL) carotid arteries.

Damages to the CAROTID ARTERIES caused either by blunt force or penetrating trauma, such as CRANIOCEREBRAL TRAUMA; THORACIC INJURIES; and NECK INJURIES. Damaged carotid arteries can lead to CAROTID ARTERY THROMBOSIS; CAROTID-CAVERNOUS SINUS FISTULA; pseudoaneurysm formation; and INTERNAL CAROTID ARTERY DISSECTION. (From Am J Forensic Med Pathol 1997, 18:251; J Trauma 1994, 37:473)

Pathological conditions involving the CAROTID ARTERIES, including the common, internal, and external carotid arteries. ATHEROSCLEROSIS and TRAUMA are relatively frequent causes of carotid artery pathology.

The splitting of the vessel wall in one or both (left and right) internal carotid arteries (CAROTID ARTERY, INTERNAL). Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the internal carotid artery and aneurysm formation.

A measurement of the thickness of the carotid artery walls. It is measured by B-mode ULTRASONOGRAPHY and is used as a surrogate marker for ATHEROSCLEROSIS.
