Insights

Most radial arteries originate normally in the cubital fossa. However, this study found variations in radial artery origin in 13.21% of specimens, highlighting potential procedural complications.

Area of Science:

  • Anatomy
  • Vascular Anatomy
  • Human Anatomy

Background:

  • The radial artery, typically originating from the brachial artery in the cubital fossa, is crucial for various cardiovascular procedures.
  • Anomalies such as high origin or tortuosity can lead to procedural failures.

Purpose of the Study:

  • To investigate the variations in the origin and course of the radial artery in adult human cadavers.

Main Methods:

  • A descriptive cross-sectional study was conducted on 53 upper limb specimens from 27 formalin-fixed cadavers.
  • Data analysis included frequency, proportion, and point estimates at a 95% confidence interval.

Main Results:

  • A normal origin of the radial artery in the cubital fossa was observed in 86.79% of specimens.
  • Variations in origin were noted in 13.21% of specimens, including origins from the axilla and different parts of the arm.
  • Bilateral radial artery tortuosity was observed in one cadaver.

Conclusions:

  • The majority of radial arteries exhibit a typical origin from the brachial artery in the cubital fossa.
  • A small percentage of radial arteries show variations in origin, which is important for clinicians to consider.

Arteries of the Upper Limbs01:12

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

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.

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:

The Arch of Aorta01:10

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

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...
