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:
Assessment of apical radial pulse01:25

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.
Pre-Procedural Preparation
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...
Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...

Area of Science:

  • Orthopedics
  • Plastic Surgery
  • Microsurgery

Background:

  • Soft tissue defects in the hand and wrist present significant challenges for surgeons.
  • The retrograde radial forearm fasciocutaneous flap is a common solution but has limitations.
  • These limitations include radial artery sacrifice, tissue mismatch, and donor site aesthetics.

Purpose of the Study:

  • To review the indications for the radial artery perforator flap in hand and wrist soft tissue defects.
  • To highlight the advantages of the radial artery perforator flap over the radial forearm flap.
  • To provide a comprehensive guide for its application in upper-extremity reconstruction.

Main Methods:

  • Review of surgical anatomy relevant to the radial artery perforator flap.
  • Discussion of operative techniques for flap harvesting and inset.
  • Outline of rehabilitation protocols, potential complications, and surgical pearls.

Main Results:

  • The radial artery perforator flap minimizes disadvantages associated with the radial forearm flap.
  • It avoids radial artery sacrifice and offers better color and bulk match with recipient tissues.
  • Improved donor site appearance is another key benefit.

Conclusions:

  • The radial artery perforator flap is an effective and versatile option for soft tissue coverage in the hand and wrist.
  • It offers significant advantages over traditional flaps, improving functional and aesthetic outcomes.
  • This flap represents a valuable tool for complex upper-extremity reconstruction.
