Resumen

Una nueva modificación del conducto protésico permite la revascularización de la arteria transcarotida (TCAR) en pacientes con una anatomía desafiante. Esta técnica amplía la aplicabilidad de TCAR, ofreciendo resultados comparables a los procedimientos estándar sin mayor riesgo.

Área de la Ciencia:

Cirugía vascular Cirugía vascular.
Cardiología Intervencionista Cardiología intervencionista.
Innovación en los dispositivos médicos Innovación en los dispositivos médicos

Sus antecedentes:

La estenosis de la arteria carótida requiere intervención, siendo la revascularización de la arteria transcarótida (TCAR) una opción viable para los pacientes de alto riesgo.
Las limitaciones anatómicas como la longitud corta de la arteria carótida común (CCA) o el trombo pueden prevenir el TCAR estándar.
La endarterectomía carotídea (CEA) y el stenting transfemoral son alternativas, pero pueden conllevar riesgos más altos.

Objetivo del estudio:

Describir y evaluar una técnica modificada de TCAR utilizando un conducto protésico.
Evaluar la viabilidad y seguridad de esta modificación en pacientes con anatomía prohibitiva para el TCAR estándar.
Para determinar si este enfoque amplía la elegibilidad de TCAR sin comprometer los resultados.

Principales métodos:

Un conducto prostético (injerto Dacron de 6 mm) fue anastomizado al CCA para crear una pista extendida.
La funda TCAR se introdujo en el conducto protésico, facilitando el acceso seguro.
Luego se completaron los procedimientos estándar de TCAR, seguidos de la ligadura y el cierre del conducto.

Principales resultados:

La técnica TCAR modificada se aplicó con éxito en tres pacientes con anatomía desafiante.
Los tiempos operativos y de inversión de flujo fueron comparables a los procedimientos convencionales de TCAR.
No se observaron complicaciones en los pacientes que se sometieron a este TCAR modificado.

Conclusiones:

El TCAR con un conducto protésico es una modificación segura y efectiva para pacientes con una longitud inadecuada del CCA o una anatomía desfavorable.
Esta técnica amplía la población de pacientes elegibles para TCAR, evitando potencialmente las intervenciones de mayor riesgo.
La modificación amplía el conjunto de herramientas del cirujano vascular, mejorando la accesibilidad de TCAR sin comprometer la seguridad o la eficiencia.

Areas Within Irregular Boundaries

Areas Within Irregular Boundaries

Calculating areas within irregular boundaries, such as along rivers or curved roads, is crucial in various fields, including surveying, engineering, and environmental management. Surveyors often begin by creating a traverse, a connected series of straight lines approximating the area's boundary. The coordinates of each traverse point are essential for calculating the enclosed area. The double meridian distance formula is a widely used technique for this purpose. This method utilizes the...

Anatomical Positions

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Anatomical Terminology

Anatomical Terminology

Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Anatomical Movements

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Electrostatic Boundary Conditions

Electrostatic Boundary Conditions

Consider an external electric field propagating through a homogeneous medium. When the electric field crosses the surface boundary of the medium, it undergoes a discontinuity. The electric field can be resolved into normal and tangential components. The amount by which the field changes at any boundary is given by the difference between the field components above and below the surface boundary.
The surface integral of an electric field is given by Gauss's law in integral form and is related to...

Magnetostatic Boundary Conditions

Magnetostatic Boundary Conditions

An electric field suffers a discontinuity at a surface charge. Similarly, a magnetic field is discontinuous at a surface current. The perpendicular component of a magnetic field is continuous across the interface of two magnetic mediums. In contrast, its parallel component, perpendicular to the current, is discontinuous by the amount equal to the product of the vacuum permeability and the surface current. Like the scalar potential in electrostatics, the vector potential is also continuous...
