Congenital portal vein hypoplasia(PVH)
Also known as: Hepatic Microvascular Dysplasia · HMD · Microvascular Dysplasia · MVD · Kongenitale Pfortaderhypoplasie · …
Overview
What it is
Congenital portal vein hypoplasia is a liver condition where the small blood vessels within the liver are underdeveloped. This underdevelopment restricts normal blood flow through the liver, preventing the organ from properly filtering toxins and waste products from the bloodstream. As a result, these unfiltered substances circulate throughout the body, which can affect overall health.
How it presents
Symptoms typically appear in young dogs and include poor growth, vomiting, lethargy, or unusual behavior and neurological signs shortly after eating. However, some affected dogs may show very mild signs or remain completely asymptomatic throughout their lives.
Treatment
While the condition cannot be cured, it is manageable with lifelong supportive care, including a special low-protein diet and medications to reduce toxin buildup. Managing this condition typically costs between 1,500 and 5,000 EUR over the dog's lifetime.
