Resumen
La hemicraniectomía descompresiva (DHC) después de la terapia endovascular (EVT) para el infarto hemisférico grande (LHI) reduce la mortalidad a los 90 días. Los pacientes con LHI de moderado a grave pueden beneficiarse más de la DHC.
Área de la Ciencia:
- Neurología
- Neurocirugía
- Medicina de Cuidados Críticos
Sus antecedentes:
- La terapia endovascular (EVT) es un tratamiento estándar para el ictus isquémico agudo.
- El infarto hemisférico grande (LHI) después de la EVT puede provocar resultados graves.
- La hemicraniectomía descompresiva (DHC) es una intervención potencial para el LHI, pero su beneficio en el contexto de la EVT requiere aclaración.
Objetivo del estudio:
- Evaluar la eficacia de la DHC en pacientes con LHI después de EVT.
- Identificar los subgrupos de pacientes con mayor probabilidad de beneficiarse de la DHC post-EVT.
Principales métodos:
- Análisis combinado de los ensayos RESCUE-RE y ANGEL-ASPECT.
- Criterios de inclusión: LHI y déficits neurológicos graves post-EVT.
- Emparejamiento por puntuación de propensión (PSM) para comparar los grupos de DHC frente a terapia conservadora.
- Resultado primario: mortalidad a los 90 días; resultado secundario: distribución de la escala de Rankin modificada (mRS) a los 90 días.
Principales resultados:
- La DHC redujo significativamente la mortalidad a los 90 días en comparación con la terapia conservadora (OR, 0.26; p=0.005).
- No se observó una mejora significativa en la distribución de la mRS a los 90 días (OR común, 0.47; p=0.06).
- Los pacientes con rangos específicos de desplazamiento de la línea media (10-17 mm) o volumen de infarto (250-330 mL) mostraron un beneficio clínico integral.
Conclusiones:
- La DHC se asocia con una menor mortalidad en pacientes con LHI post-EVT cuando se realiza según las directrices.
- Los pacientes con una gravedad de lesión de moderada a alta después de la EVT pueden obtener el mayor beneficio de la DHC.
- Investigaciones adicionales pueden refinar la selección de pacientes para la DHC después de la EVT.

Cerebral Hemispheres
2.2K
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Gene Therapy
27.4K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Group therapy is a sociocultural approach to psychological treatment, where individuals with shared psychological challenges come together under the guidance of a mental health professional. This therapeutic modality offers unique opportunities for individuals to connect, share, and grow within the context of a supportive group. By fostering mutual understanding and collaboration, group therapy can address a range of psychological concerns effectively, often complementing or surpassing the...

Psychodynamic Therapy

Psychodynamic therapies emphasize the exploration of unconscious processes and early childhood experiences as fundamental contributors to psychological difficulties. These therapies, deeply rooted in Freud's psychoanalytic theory, aim to uncover and resolve unconscious conflicts, granting individuals insights that promote emotional and behavioral healing. Contemporary psychodynamic approaches have evolved, integrating a broader range of influences and methodologies while still valuing the...

Humanistic Therapy

Humanistic therapies emphasize personal growth, self-understanding, and the fulfillment of human potential. Rooted in the belief that individuals inherently strive toward self-actualization, these approaches encourage clients to explore their feelings and experiences in a supportive, nonjudgmental environment. Humanistic therapies differ from psychodynamic approaches by focusing on conscious experiences, present circumstances, and the potential for self-improvement rather than past conflicts...

Modeling in Therapy
395
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
