Summary
An arteriovenous fistula (AVF) is a rare complication of axillary plexus blocks. Early diagnosis and treatment are crucial for managing this vascular complication and preventing false aneurysms.
Area of Science:
- Vascular Surgery
- Anesthesiology
- Radiology
Background:
- Axillary plexus blocks are commonly used for upper extremity surgery.
- Complications, though rare, can occur and require careful monitoring.
Observation:
- A pulsatile mass developed in the axilla one day after an axillary plexus block.
- The mass gradually enlarged and became painful over four years.
- Digital subtraction angiography confirmed an axillary arteriovenous fistula (AVF) involving the axillary artery and vein.
Findings:
- Surgical excision of the false aneurysm sac and lateral repair of the axillary artery and vein were performed.
- The patient experienced an uneventful postoperative recovery.
Implications:
- This case highlights the importance of considering AVF as a potential complication of axillary plexus blocks.
- Prompt diagnosis and intervention are necessary to prevent the development of AVF and associated false aneurysms.
- Awareness among clinicians can lead to earlier detection and improved patient outcomes.

01:25Hemodialysis 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...
01:12Arteries 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...
01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:17Veins of Upper Limbs
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
