Understanding the Vascular Anatomy of the Arm

Sep 1, 2024

Lecture on the Vascular Arm

Overview

The lecture covers the vascular anatomy of the left arm, focusing on both arteries and veins. The presentation starts with the arteries, moving from the axillary artery downwards, and then covers the veins from the distal end back up to the axillary region.

Arteries

  • Axillary Artery
    • Continuation from the subclavian artery.
    • Branches:
      • Anterior Humeral Circumflex Artery
      • Posterior Humeral Circumflex Artery
  • Brachial Artery
    • Major continuation of the axillary artery.
    • Branches:
      • Deep Brachial Artery
      • Superior Ulnar Collateral Artery
      • Inferior Ulnar Collateral Artery
  • Radial Artery
    • Extends down the thumb side of the forearm.
  • Ulnar Artery
    • Extends down the pinky side of the forearm.
    • Branch: Common Interosseous Artery
      • Splits into:
        • Posterior Interosseous Artery
        • Anterior Interosseous Artery
  • Palmar Arches
    • Superficial Palmar Arch
    • Deep Palmar Arch
  • Dorsal Carpal Arch
    • Connects to the Dorsal Metacarpal Arteries

Veins

  • Palmar Digital Veins
    • Form part of the Palmar Venous Arch
  • Dorsal Digital Veins and Dorsal Metacarpal Veins
    • Participate in venous drainage from the dorsal aspect.
  • Basilic Vein
    • Located on the ulnar side and feeds into the brachial vein.
  • Cephalic Vein
    • Located on the radial side and connects directly to the axillary vein.
  • Median Antebrachial Vein
    • Also known as the median vein.
  • Median Antecubital Vein
    • Common site for venipuncture.
  • Radial and Ulnar Veins
    • Accompany their respective arteries.
    • Merge to form the Brachial Vein.
  • Axillary Vein
    • Receives blood from the brachial vein and cephalic vein.

Conclusion

The lecture provided a detailed walkthrough of the arteries and veins in the left arm. Understanding the vascular anatomy is crucial for clinical applications such as venipuncture and surgical interventions. The speaker encouraged viewers to engage on social media and support through Patreon.
