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.

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:

Arteries of the Upper Limbs

547
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...

Summary
This summary is machine-generated.

Radial artery grafts offer a superior alternative to vein grafts in coronary artery surgery. A rare anatomical variation, the superficial radial artery, necessitates careful consideration during graft selection to ensure adequate blood supply.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Anatomy

Background:

  • Coronary artery bypass grafting (CABG) frequently utilizes arterial and venous grafts.
  • Internal thoracic artery (ITA) and radial artery (RA) grafts are increasingly preferred over saphenous vein grafts.
  • The combination of ITA and RA grafts presents a viable alternative to bilateral ITA grafting.

Observation:

  • Two CABG patients were planned for left ITA to the left anterior descending artery and left RA as the secondary graft.
  • A rare anatomical variation presented as a superficial radial artery in both patients.
  • The superficial location of the radial artery necessitated its exclusion as a graft conduit.

Findings:

  • The superficial radial artery variation is exceptionally rare, occurring in approximately 0.02% of cases based on the authors' experience.

  • Excluding the superficial radial artery ensured adequate blood supply to the palmar arch.
  • This anatomical anomaly prevented potential inadequacy in coronary graft length.

    • Implications:

    • Surgeons must be aware of rare radial artery anatomical variations during coronary artery bypass surgery.
    • Careful preoperative assessment is crucial for selecting appropriate arterial conduits.
    • Understanding vascular anatomy variations is vital for optimizing surgical outcomes and preventing graft-related complications.
