Preliminary experience with the micro vascular plug for the treatment of pulmonary arteriovenous malformation: case series of four patients

BACKGROUND: To describe the preliminary experience using Micro Vascular Plug (MVP) for treatment of pulmonary arteriovenous malformations (PAVMs) with small feeding arteries (3 -5 mm) in four patients with Hereditary Haemorrhagic Telangiectasia (HHT). MATERIAL AND METHODS: One female and three male patients with PAVMs have been treated during 2017. The mean age was 32.5 years; (range: 20–53). All patients underwent contrast echocardiography and computed tomography of the chest to establish the diagnosis. RESULTS: Four patients with PAVMs were treated with embolisation using the MVP-3Q and MVP-5Q micro plugs. All MVP were placed without complications and with following immediate occlusion of the PAVMs in all three cases. In one case MVP was placed semi selectively. All cases were with the good clinical outcomes. CONCLUSION: MVP is a new detachable embolisation material which is easy to use. Maximal control during the deployment and immediate occlusion of the target vessels can be achieved.
