Resumen

Se encontró una arteria radial de origen alto (AR) en el 11,5 % de las variaciones de la arteria braquial (AB) en cadáveres del Medio Oeste. La comprensión de estas anomalías de ramificación arterial es crucial para los procedimientos médicos.

Área de la Ciencia:

Anatomía; Biología Vascular; Imagenología Médica

Sus antecedentes:

La arteria braquial (AB) se bifurca en la arteria radial (AR) y la arteria cubital, suministrando sangre al antebrazo y la mano.; Las variaciones anatómicas en la ramificación de la AB pueden afectar los procedimientos clínicos.; La nomenclatura estándar para los puntos de referencia arteriales puede ser inconsistente.

Objetivo del estudio:

Determinar la frecuencia y las características morfológicas de las arterias radiales de origen alto (AR).; Investigar las variaciones en la bifurcación de la arteria braquial (AB) en especímenes cadavéricos del Medio Oeste.

Principales métodos:

Evaluación de la ramificación de la arteria braquial (AB) en 31 cadáveres del Medio Oeste.; Caracterización de las arterias radiales de origen alto (AR), incluido el origen, el curso y la longitud.; Documentación mediante fotografía.

Principales resultados:

Se analizaron sesenta y un miembros superiores.; Se observaron siete casos (11,5 %) con variaciones en la bifurcación de la AB originadas en la arteria axilar.; Se observaron variaciones tanto en miembros derechos (57,1 %) como izquierdos (42,9 %).

Conclusiones:

Más de una décima parte de las arterias braquiales (AB) presentan variaciones en sus patrones de ramificación.; La concienciación sobre estas variaciones anatómicas es vital para procedimientos como la angiografía coronaria y las intervenciones percutáneas.

Palabras clave:

Assessment of radial pulse

Assessment of radial pulse

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Arteries of the Upper Limbs

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Assessment of apical radial pulse

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Pulse Assessment Sites

Pulse Assessment Sites

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
