Summary

A patient with a rare bifid axillary artery required an alternative anesthetic approach. An interscalene block was chosen over an axillary block due to potential neurologic risks associated with this vascular anomaly.

Area of Science:

  • Vascular Surgery
  • Anesthesiology
  • Anatomy

Background:

  • Axillary blocks are commonly used for vascular access anesthesia.
  • Anatomical variations can impact anesthetic technique selection.
  • Bifid axillary artery is a rare vascular anomaly.

Purpose of the Study:

  • To describe the anesthetic management of a patient with a bifid axillary artery.
  • To discuss the implications of this anomaly for axillary block procedures.
  • To highlight the importance of pre-procedural imaging and planning.

Main Methods:

  • Case report of a patient undergoing vascular access.
  • Physical examination and ultrasound to identify vascular anatomy.
  • Selection of interscalene block based on identified anomaly and associated risks.

Main Results:

  • A bifid axillary artery was identified in the patient.
  • Neurologic anomalies were associated with the vascular variation.
  • An interscalene block was successfully performed.

Conclusions:

  • Bifid axillary artery necessitates careful consideration for axillary block.
  • Interscalene block may be a safer alternative in such cases.
  • Pre-procedural ultrasound is crucial for identifying vascular anomalies and guiding anesthetic choices.
