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.

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...

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:
Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation01:21

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

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...
Hemodialysis I: Introduction01:25

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Summary

If the non-dominant radial artery is unsuitable for harvesting, there

Area of Science:

  • Vascular Surgery
  • Cardiovascular Research

Background:

  • Radial artery is the preferred graft for coronary artery bypass grafting.
  • Harvesting is typically from the non-dominant hand to preserve dominant hand function.
  • The suitability of the dominant radial artery when the non-dominant is compromised needs investigation.

Purpose of the Study:

  • To assess contraindications for dominant radial artery harvest when the non-dominant artery is unsuitable.
  • To compare anatomical and circulatory parameters between dominant and non-dominant radial arteries.

Main Methods:

  • Allen test, upper arm Doppler ultrasonography, and digital plethysmography were performed on 33 patients with non-dominant radial artery contraindications.
  • Anatomical and circulatory measurements were taken.

  • Twelve control patients without non-dominant radial artery contraindications were also examined.

    • Main Results:

    • All 33 patients had contraindications in the non-dominant radial artery.
    • Seventy-three percent (24/33) also had contraindications in the dominant radial artery.
    • While morphology showed no significant difference, circulatory parameters indicated contraindication in the dominant hand for a majority.

    Conclusions:

    • A high risk of contraindication exists for the dominant radial artery if the non-dominant artery is unsuitable for harvesting.
    • Circulatory parameters, not morphology, are key indicators for contraindication in the dominant radial artery.
    • Careful pre-operative assessment of both radial arteries is crucial for coronary artery bypass grafting.
