Arteries of the Upper Limbs

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 Limbs

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...

Arteries of Lower Limbs

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...

Bones of the Upper Limb: Ulna

Bones of the Upper Limb: Ulna

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...

Anatomy of Blood Vessels

Anatomy of Blood Vessels

The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta,...

Veins of Head and Neck

Veins of Head and Neck

The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Background:

Upper limb approaches for cardiac catheterization and percutaneous coronary intervention (PCI) are increasingly preferred over transfemoral access.
These methods offer benefits such as reduced bleeding, enhanced patient comfort, and faster ambulation.

Purpose of the Study:

To explore the spectrum of upper extremity vascular anomalies.
To discuss the clinical implications of these variations for transradial and transulnar cardiac catheterization and PCI.

Main Methods:

Review of current literature on upper limb vascular anatomy and its variations.
Analysis of clinical implications in the context of cardiac catheterization and PCI.

Main Results:

Knowledge of upper limb vascular anatomy, including congenital and acquired variations, is essential for procedural success.
Anomalies can impact the safety and efficacy of transradial and transulnar access.

Conclusions:

A comprehensive understanding of upper extremity vascular anatomy and its anomalies is critical for interventional cardiologists.
Optimizing patient selection and procedural techniques based on vascular variations improves outcomes for transradial and transulnar cardiac interventions.
