Insights

Transcarotid artery revascularization (TCAR) offers a safe and effective treatment for severe carotid artery stenosis in high-risk patients. This minimally invasive approach utilizes a temporary fistula for neuroprotection, ensuring successful stenting and positive long-term outcomes.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Neurology

Background:

  • Carotid endarterectomy is the standard treatment for carotid stenosis.
  • Transfemoral carotid artery stenting is an alternative for high-surgical-risk patients.
  • Transcarotid artery revascularization (TCAR) shows promising results.

Purpose of the Study:

  • To evaluate the safety and efficacy of TCAR in a patient with severe carotid stenosis and high surgical risk.
  • To describe the technique of TCAR with flow reversal for neuroprotection.

Main Methods:

  • A 68-year-old male with hypertension and COPD presented with stroke due to severe right internal carotid artery stenosis.
  • TCAR was selected due to lesion location and patient's surgical risk.
  • A temporary fistula between the carotid artery and jugular vein was created for flow reversal and neuroprotection during stent deployment.

Main Results:

  • The TCAR procedure was successfully completed without complications.
  • The patient remained asymptomatic at the one-year follow-up.
  • TCAR demonstrated effective revascularization and neuroprotection.

Conclusions:

  • TCAR is a safe and effective alternative for carotid artery revascularization in high-risk patients.
  • The use of a temporary fistula for neuroprotection during TCAR is a viable technique.
  • TCAR provides a promising option for managing complex carotid stenosis.

Blood Flow01:29

Blood Flow

Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.
Laminar and Turbulent Flow01:07

Laminar and Turbulent Flow

Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the streamlines...
Autoregulation of Blood Flow01:17

Autoregulation of Blood Flow

Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
Chemical Signaling in Autoregulation
Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation.
Steady Flow of a Fluid Stream01:27

Steady Flow of a Fluid Stream

Consider a control volume, such as a pipe with solid boundaries, through which fluid flows and changes direction due to the impulse exerted by the resulting force from the pipe walls. In steady flow, the mass of fluid entering the control volume at a given time, t, with velocity v1, is equal to the mass leaving after infinitesimal time dt, with velocity v2.
During this process, the momentum of the fluid within the control volume remains constant over the time interval dt. By applying the...
Gradually Varying Flow01:29

Gradually Varying Flow

Gradually varying flow (GVF) in open channels describes situations where water depth changes slowly along the channel due to factors like non-uniform bed slope, channel shape variations, or obstructions. This flow type occurs when the depth adjusts gradually to balance gravitational forces, shear forces, and energy requirements, resulting in a low rate of depth change.Characteristics of Gradually Varying FlowGVF is commonly observed in natural streams, rivers, and canals, where flow depth...

Applications of Integration to Find Blood Flow

Blood flow through a cylindrical blood vessel can be mathematically described using the principles of laminar flow, a regime in which fluid moves smoothly in parallel layers. In this model, the velocity of the blood is not uniform across the cross-section of the vessel; rather, it varies with the radial distance from the center. The maximum velocity occurs along the central axis, decreasing progressively toward the vessel walls, where it reaches zero due to viscous drag.Approximating Blood...
