Beyond Breathless: Unravelling The Enigma Of Pulmonary Arteriovenous Malformations, Sri Mounya Jampala, Jagadish Kumar K Dr., Manjunath V G, Nandish H R

Digital Journal of Clinical Medicine

Pulmonary Arteriovenous Malformations (AVMs) are abnormal connections between the pulmonary arteries and veins, leading to a direct shunting of blood without passing through the normal capillary bed. These AVMs can be associated with a rare genetic disorder called Hereditary Hemorrhagic Telangiectasia (HHT), also known as Osler-Weber-Rendu syndrome. HHT is an autosomal dominant disorder characterized by the development of fragile telangiectasias in various organs, including the skin and mucous membranes. These telangiectasias are prone to bleeding, leading to recurrent nosebleeds and mucocutaneous bleeding. In patients with HHT, the most common site of AVMs is in the lungs. Pulmonary AVMs can cause …
