Insights

This study details variations in the radial artery

Area of Science:

  • Anatomy
  • Vascular Surgery

Background:

  • Coronary artery bypass grafting is a key treatment for advanced coronary artery disease.
  • The radial artery is increasingly used for coronary angiography access.
  • Understanding radial artery anatomy is crucial for surgical patient care.

Purpose of the Study:

  • To investigate variations in the branching pattern and termination of the radial artery.
  • To provide anatomical data relevant to surgical and radiological interventions.

Main Methods:

  • Analysis of 75 formalin-fixed upper limbs.
  • Detailed examination of radial artery branching and termination patterns.

Main Results:

  • Observed variations in radial artery bifurcation (2.7% three branches, 52.0% two branches).
  • Identified instances of radial recurrent artery originating from the brachial artery (12.0%).
  • Documented absence of specific branches, including the palmar carpal artery (26.7%) and superficial palmar artery (5.3%).

Conclusions:

  • The documented variations in radial artery anatomy are of academic significance.
  • This anatomical knowledge is valuable for surgeons and radiologists performing procedures in the upper limb and cardiac regions.

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...

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...

Arteries of Lower Limbs

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
