Resumen
La embolización transvenosa con detención del flujo ofrece un enfoque novedoso para el tratamiento de malformaciones arteriovenosas (MAV) complejas del tronco encefálico. Esta técnica tiene como objetivo mejorar las tasas de obliteración al detener temporalmente el flujo sanguíneo durante la embolización.
Área de la Ciencia:
- Neurología
- Neurorradiología Intervencionista
- Neurocirugía
Sus antecedentes:
- Las malformaciones arteriovenosas (MAV) del tronco encefálico son raras y plantean importantes desafíos quirúrgicos debido a su ubicación.
- Las MAV del tronco encefálico rotas tienen un alto riesgo de mortalidad y resangrado.
Objetivo del estudio:
- Describir una técnica novedosa de embolización transvenosa para MAVs del tronco encefálico.
- Demostrar la eficacia de la detención simultánea del flujo arterial y venoso en la mejora de la obliteración de la MAV.
Principales métodos:
- Informe de caso que detalla el tratamiento de una MAV del tronco encefálico rota en un paciente varón de unos 50 años.
- Embolización líquida transvenosa con Onyx con detención simultánea del flujo arterial y venoso mediante catéteres de balón (HyperGlide y Scepter C).
Principales resultados:
- La obliteración exitosa de la MAV del tronco encefálico se logró utilizando la técnica descrita.
- El método simultáneo de detención del flujo facilitó la reducción del flujo intranidal y mejoró la oclusión nidal.
Conclusiones:
- La embolización transvenosa con detención del flujo arterial y venoso es una técnica prometedora para el tratamiento de MAVs complejas del tronco encefálico.
- Este enfoque puede ofrecer mejores resultados para casos de MAVs difíciles.

6.0K
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

558
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

The medulla oblongata is a crucial part of the brainstem responsible for controlling various autonomic and involuntary functions. It contains several nuclei, including the olivary, cuneate, gracile, and solitary nuclei.
Olivary Nucleus
The olivary nucleus, or inferior olivary nucleus, is located within the ventrolateral part of the medulla oblongata. It is primarily involved in motor coordination and motor learning. The olivary nucleus receives input from the spinal cord, cerebellum, and motor...

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...
