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 Artery Disease III: Interprofessional Care

649
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...

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.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Nephrology

Background:

  • Percutaneous vascular access typically uses cephalic or basilic veins.
  • The transradial approach, proven in coronary interventions, is explored for arteriovenous fistula stenosis.
  • End-stage renal disease necessitates reliable vascular access for hemodialysis.

Purpose of the Study:

  • To evaluate the safety and feasibility of the transradial approach for endovascular intervention of peri-anastomotic arteriovenous fistula stenosis.
  • To assess the technical success and patency rates of this novel technique.

Main Methods:

  • Thirty patients with end-stage renal failure underwent transradial vascular access intervention.
  • A 4-French (Fr) micropuncture kit was used, with sheath size upgraded as needed (5-Fr or 6-Fr).
  • Angioplasty was performed for residual stenosis, with outcomes assessed via Duplex scan and photoelectric plethysmography.

Main Results:

  • Technical success for access and angioplasty (residual stenosis <30%) was achieved in all patients.
  • No peri-procedural complications were reported.
  • Primary patency was 100% at 6 months, decreasing to 32.8% at 12 months. Primary assisted patency was 100% at 6 months, increasing to 63.3% at 12 months.
  • Freedom from significant radial artery restenosis was 92.4% at 12 months.

Conclusions:

  • The transradial approach is technically feasible and safe for vascular access endovascular interventions.
  • This technique enables simultaneous treatment of peri-anastomotic fistula lesions and arterial inflow/outflow lesions.
  • It offers a viable alternative for managing complex arteriovenous fistula stenosis.
