Summary
Anatomical variations in the upper limb arterial system are common. This case details a superficial brachial artery, a rare variant important for surgical and interventional procedures.
Area of Science:
- Anatomy
- Vascular Anatomy
- Embryology
Background:
- The upper extremity arterial system exhibits significant variability due to complex embryonic development.
- Awareness of these arterial variations is crucial given the upper limb's susceptibility to injury.
- The brachial artery is vital for procedures like cardiac catheterization, angioplasty, pedicle flaps, and arterial grafting.
Observation:
- This report documents a case of a superficial brachial artery.
- The brachial artery originated normally but coursed superficial to the median nerve.
- The variation was observed approximately five cm above the intercondylar line.
Findings:
- The superficial brachial artery bifurcated into the radial and ulnar arteries.
- This specific anatomical variation, the superficial brachial artery, has a reported prevalence ranging from 0.2% to 25%.
Implications:
- Accurate knowledge of major arterial conduits and their variations is essential for effective reparative surgery in the arm, forearm, and hand.
- Understanding such variations aids in preventing iatrogenic injuries during surgical and interventional procedures.
- This anatomical knowledge is critical for successful outcomes in reconstructive surgery and endovascular interventions involving the upper limb vasculature.

01:12Arteries 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...
01:17Veins 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...

01:10The 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.

01:21Sites 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 human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:20Arteries 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,...
