Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

2.9K
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

5.1K
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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

10.5K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

627
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...

Assessment of radial pulse01:11

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:

Spinal Nerves: Plexus I01:22

Spinal Nerves: Plexus I

3.4K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Area of Science:

  • Anatomy
  • Vascular Surgery
  • Surgical Anatomy

Background:

  • Anatomical variations of upper limb arteries are frequent and require thorough understanding for safe surgical interventions.
  • Knowledge of these variations is essential to minimize surgical morbidity and optimize reconstructive procedures.

Observation:

  • The superficial ulnar artery is the second most common arterial variation in the upper limb, following radial artery origin variations.
  • This variation was identified intraoperatively during a radial forearm free flap harvest.

Findings:

  • The study presents a case of a superficial ulnar artery discovered during surgery.
  • A review of cases was conducted to determine the frequency of this anatomical variation and compare it with existing literature.

Implications:

  • Identifying the superficial ulnar artery can modify reconstructive surgical techniques, particularly when selecting this vessel for forearm free flaps.
  • Awareness of this arterial variation is critical for surgeons to ensure procedural safety and efficacy in plastic and reconstructive surgery.
