Abstract
Pulmonary arteriovenous malformations (PAVM) are rare anomalies of pulmonary vascular system which may be incidentally detected or can have manifestations resulting from right to left shunt. PAVM can cause various systemic implications including central nervous system complications like stroke, brain abscess due to paradoxical emboli which mostly seen in previously undiagnosed PAVMs indicating importance of early diagnosis and timely intervention in PAVM. Computed Tomography Pulmonary Angiography (CTPA) is the diagnostic method of choice in PAVM. We present here a unique case of complex multiple PAVM presented with refractory hypoxemia in a middle aged patient diagnosed in our centre initially evaluated for malignancy based on chest radiography & High Resolution Computed tomography(HRCT)thorax findings and symptoms, later on after CTPA was diagnosed to have complex PAVM which showed clinicoradiological improvement following pulmonary vascular plugging. This case shows clinical scenario, diagnostic & management methods and differential diagnosis to be discussed in similar clinicoradiological pattern and peculiarity of PAVM despite advanced age.
Highlights
Pulmonary arteriovenous malformations (PAVMs) are rare abnormalities of the pulmonary vascular system [1] which are characterized by an abnormal communication between the pulmonary artery and vein, which result in a low resistant right-to-left shunt
The disease was first described at an autopsy in 1897 and first diagnosed during life in 1939 [2]. approximately 70% of PAVMs are associated with hereditary haemorrhagic telangiectasia (HHT), and about 15-30% of individuals with HHT have a PAVM
Pulmonary arteriovenous malformations (PAVM) are the pulmonary vascular abnormality caused by abnormal direct communications between pulmonary arteries and veins without an intervening capillary bed
