๐ง Are We Missing Half of the Brain's Circulation?
For decades, neurocritical care has focused primarily on arterial flow.
We monitor cerebral perfusion, vasospasm, autoregulation, pulsatility indices, and intracranial pressure. Yet one critical component of intracranial hemodynamics remains largely overlooked:
Cerebral venous outflow.
A recent review in Diagnostics argues that Transcranial Color Doppler (TCCD) should evolve beyond being merely the "stethoscope of the brain" for arterial circulation and begin incorporating systematic assessment of cerebral venous drainage.
The authors highlight a simple but important physiological concept:
๐ฉธ Intracranial hypertension is not only a problem of arterial inflow.
It may also be a problem of impaired venous outflow.
Mechanical ventilation, elevated PEEP, hypercapnia, increased intra-abdominal pressure, Trendelenburg positioning, cardiac tamponade, pulmonary hypertension, large-bore jugular catheters, and venous obstruction can all impair cerebral venous drainage and contribute to cerebral congestion.
Using venous TCCD combined with internal jugular vein ultrasound, clinicians may be able to detect cerebral venous congestion before conventional markers such as optic nerve sheath diameter (ONSD) enlargement or arterial Doppler changes become evident.
Particularly interesting for intensivists and anesthesiologists, the review presents clinical examples where:
๐น Mechanical ventilation reduced Rosenthal vein flow despite stable arterial Doppler findings.
๐น Large-bore central venous catheters further impaired cerebral venous drainage.
๐น Hemodynamically significant pericardial effusion produced profound venous congestion detectable by ultrasound before definitive diagnosis.
๐น Pneumoperitoneum and Trendelenburg positioning increased jugular venous congestion during surgery.
The key message is not that venous TCCD replaces current neuromonitoring tools.
Rather, it may provide an additional physiological layer that helps explain why some patients develop intracranial hypertension despite apparently acceptable arterial parameters.
As critical care increasingly moves toward physiology-guided management, perhaps the next frontier is understanding not only how blood enters the brain, but also how it leaves it.
Question for the neurocritical care and perioperative community:
Do you routinely consider cerebral venous drainage when adjusting PEEP, patient positioning, pneumoperitoneum pressures, or central venous access strategies?

Platicando con mi compaรฑera de vida comentamos que muchas veces los mรฉdicos cargan con sus decesos: los Psiquiatras con los suicidios, los Ginecos con los bebรฉs, los Clรญnicos acompaรฑan a sus pacientes hasta la muerte, los quirรบrgicos tomando decisiones de rรกpida para no complicarse. Algunos se enfrรญan en el camino la disociaciรณn o la falta de empatรญa los protege y ya vienen distanciados a la condiciรณn humana pero siendo buenos tรฉcnicos. Otros mรกs sensibles es un golpe irreparable y mรกs en las condiciones que se presenta, inevitable no mezclar el sentido de responsabilidad y la culpa asรณmandose en el sรณtano. Pero tienes que seguir. Los riesgos de esta profesiรณn son muchos pero alguien tiene que hacer este trabajo y muchas veces no se sabe como lidiar con esos procesos tan complejos. Algunos se malignizan y otros se vulnerabilizan.
Today's Paper of the Day is:
Protective nutrition strategy in the acute phase of critical illness: why, what and how to protect
https://t.co/JKgcYjlUQ5
Join us to read 1 paper per day and stay up-to-date as we cover the spectrum of critical care across 2026
๐ง Fluid Responsiveness โ Fluid Tolerance
For years, critical care clinicians have focused on a fundamental question:
Will this patient increase cardiac output if I give fluids?
A new multicentre study from France and China suggests we may need to ask a second question:
What price will the patient pay for that fluid?
In this observational study of 64 critically ill patients receiving a standardized 500 mL fluid challenge, investigators evaluated not only cardiac index (CI), but also venous congestion using VExUS and pulmonary congestion using extravascular lung water (EVLWI).
The findings are striking.
Before fluid administration, venous congestion could coexist with fluid responsiveness. In fact, many patients remained preload responsive despite already demonstrating evidence of systemic venous congestion.
However, what happened after fluid administration was even more important.
Among fluid responders:
โ Cardiac index increased significantly
โ Venous congestion remained largely stable
โ Only 5% experienced worsening VExUS grade
โ Lung water remained relatively unchanged
Among fluid non-responders:
โ Cardiac output barely changed
โ Venous congestion worsened dramatically
โ VExUS deterioration occurred in 73%
โ EVLWI increased significantly
โ Congestion became evident across hepatic, portal, and renal venous territories
Perhaps the most important physiological message is this:
When the heart cannot convert preload into flow, the fluid has to go somewhere.
And where it goes is congestion.
The study also found a strong correlation between CVP and VExUS, suggesting that while advanced ultrasound provides valuable organ-level information, a carefully interpreted CVP may still remain a useful bedside marker of right-sided congestion.
The ARDS subgroup provides another important lesson.
Even fluid-responsive ARDS patients accumulated more extravascular lung water after fluid administration than non-ARDS patients, highlighting the role of pulmonary permeability in determining fluid tolerance.
This study reinforces a concept that is increasingly central to modern hemodynamic management:
The goal is not simply to identify fluid responsiveness.
The goal is to identify patients who are both:
โ Fluid responsive
โ Fluid tolerant
A fluid challenge that increases congestion without increasing flow is not resuscitation.
It is fluid accumulation.
The future of hemodynamic management may lie at the intersection of:
โข Fluid responsiveness
โข Venous congestion assessment
โข Pulmonary permeability
โข Organ-specific fluid tolerance
Because the best fluid is not the one that can be given.
It is the one that provides benefit without causing harm.
