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...
Veins of Upper Limbs01:17

Veins of Upper Limbs

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
Sites for measuring blood pressure01:21

Sites for measuring blood pressure

Blood pressure measurement is a fundamental clinical procedure, providing crucial data for assessing cardiovascular health. Among the various sites for this measurement, the brachial and popliteal arteries are predominantly utilized due to their accessibility and the reliability of their readings. This lesson delves into the anatomical significance, methodology, and considerations of measuring blood pressure at these locations.

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...

Assessment of blood pressure in brachial artery(two-step method)

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...

Summary

A rare bilateral variation of the superficial brachial artery, where the axillary artery bifurcated unusually on both sides, is reported. This anatomical anomaly has significant clinical and radiological implications.

Area of Science:

  • Anatomy
  • Vascular Radiology
  • Clinical Procedures

Background:

  • Variations in the upper limb arterial system are common.
  • Understanding axillary artery anatomy is crucial for medical interventions.

Observation:

  • A rare bilateral variation of the superficial brachial artery was identified.
  • The axillary artery divided into a superficial brachial artery and the brachial artery proper on both sides.

Findings:

  • The superficial brachial artery passed superficial to the lateral root of the median nerve.
  • The brachial artery proper descended deep to the medial root of the median nerve, giving off circumflex humeral and profunda brachii branches.

Implications:

  • This rare bilateral variation necessitates careful consideration in vascular radiology and surgical planning.
