ABSTRACT

Among pulmonary vascular anomalies are arteriovenous malformation (AVM) featured by miscommunication between pulmonary arteries and veins. These unusual communications allow the unoxygenated blood to escape the standard capillary beds within the lung. AVMs cause right-to-left shunts, paradoxical embolization with hypoxemia. Clinical signs and symptoms differ according to the size, number, and blood flow within the AVMs. Among of the treatment modalities, transcatheter embolization is the preferred for managing pulmonary AVMs. Although, this technique is ineffective in cases with large AVM or having multiple affected main arteries which are managed mainly by surgical resection. The current case report focuses on a patient with a giant pulmonary AVM measuring 4.8 x 5.6 x 6.2 cm with a single feeding artery that pre-operatively managed with vascular plug embolization.
