Lobar Embolization for Treatment of Diffuse Pulmonary Arteriovenous Malformations in Hereditary Hemorrhagic Telangiectasia: A Case Report

Lobar occlusion of pulmonary arteriovenous malformations with Amplatzer vascular plug

“…Compared with coils, AVP for embolization of PAVM is associated with a significantly lower rate of re‐canalization of feeding vessels . There have been few reports on lobar embolization for PAVM . In the present case, use of AVP successfully achieved safe and minimally invasive complete occlusion of the left lower lobar arteries in a 10‐year‐old boy with diffuse PAVM, which are considered to be indications for surgical lobectomy.…”

“…7,12 The standard treatment for PAVMS is arterial embolization, as pulmonary lobectomy is a procedure with risks of its own. 3,7,8,10 Unfortunately, after her first neurologic complication, she was not offered arterial embolization of the PAVMs, enabling other complications like brain abscesses, as was the case. Fortunately, she recovered from the deficits, and underwent arterial embolization of the PAVMs, and later lobar pneumectomy, presenting no further neurologic complications related to the arteriovenous malformations to date.…”

“…[1][2][3][4][5] Neurologic complications can arise from paradoxical embolism due to pulmonary arteriovenous malformations (PAVMS) and are potentially fatal. 1,3,4,[6][7][8][9] Giving the low prevalence of HHT, these complications are often regarded as isolated events, enabling further complications. 4,7 We report a case of a patient that presented two of the most devastating complications of PAVMs.…”
