Pulmonary Arteriovenous Malformation (AVM) Closure
This condition occurs when arteries and veins have abnormal connections between them. Pulmonary AVMs act as direct conduits between the pulmonary artery and the pulmonary vein, which reduces blood oxygen levels, and also allows clots and bacteria to bypass the normal filtration process of the lung capillaries. Pulmonary AVMs are prone to rupturing, causing serious bleeding.
Solutions in Pulmonary AVM Closure
Embolization or blockage of pulmonary AVMs can reduce these risks. An interventional cardiologist uses X-rays to guide a small catheter from the femoral vein at the groin and into the pulmonary arteries. Contrast dye is injected to locate the pulmonary AVMs. Each AVM is then accessed using a catheter or microcatheter, and blocked with small fibered coils or plugs.
