Arteriovenous malformations (AVMs) are abnormal connections between arteries and veins that bypass the capillary system. When they occur in the urologic tract, they can lead to various health issues. This guide will break down AVMs in simple terms, covering their pathophysiology, types, causes, symptoms, diagnostic tests, treatments, and more.
Pathophysiology
Structure and Function
- Arteries: These are blood vessels that carry oxygen-rich blood from the heart to various parts of the body.
- Veins: These carry oxygen-poor blood back to the heart.
- Capillaries: Tiny blood vessels where the exchange of oxygen and nutrients occurs.
In an AVM, arteries and veins are directly connected, which can disrupt normal blood flow and pressure.
Blood Supply
AVMs in the urologic tract can disrupt blood flow to the kidneys, bladder, and other urinary organs, potentially leading to complications like hypertension and kidney damage.
Nerve Supply
Nerve connections in the urologic system are affected by AVMs, which can lead to altered sensations or pain.
Types of Arteriovenous Malformations
- Congenital AVMs: Present at birth and develop during fetal growth.
- Acquired AVMs: Develop due to injury or other medical conditions.
- Micro-AVMs: Very small connections that may not cause noticeable symptoms.
- Large AVMs: Significant connections that can lead to serious complications.
- Single AVM: Involves one specific area.
- Multiple AVMs: Involves various areas of the urologic tract.
