Insights

Distal transradial access (dTRA) significantly reduces radial artery occlusion (RAO) after percutaneous coronary interventions compared to conventional transradial access (cTRA). This approach also shortens compression time, improving patient outcomes.

Area of Science:

  • Cardiovascular Interventions
  • Vascular Access Techniques
  • Interventional Cardiology

Background:

  • Radial artery occlusion (RAO) is a potential complication of transradial access in percutaneous coronary interventions (PCIs).
  • Comparing distal transradial access (dTRA) and conventional transradial access (cTRA) is crucial for optimizing PCI procedures.

Purpose of the Study:

  • To investigate the incidence of RAO following dTRA versus cTRA.
  • To compare the advantages and disadvantages of dTRA and cTRA in PCIs.

Main Methods:

  • Retrospective analysis of 110 patients undergoing PCIs.
  • Comparison of RAO incidence between dTRA (n=56) and cTRA (n=54) groups.

Main Results:

  • RAO incidence was significantly lower in the dTRA group than in the cTRA group (P<0.05).
  • Independent risk factors for RAO included postoperative arterial compression time and dTRA (multivariable analysis).
  • Smoking and radial artery spasm were also identified as exposure factors for RAO.

Conclusions:

  • Distal transradial access (dTRA) is associated with a decreased incidence of radial artery occlusion (RAO).
  • dTRA shortens postoperative arterial compression time compared to the conventional transradial approach (cTRA).

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:

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.

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

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...

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...
