Pulmonary Arteriovenous Malformations (PAVMs) in Hereditary Haemorrhagic Telangiectasia (HHT)

Pulmonary Arteriovenous Malformations (PAVMs) in Hereditary Haemorrhagic Telangiectasia (HHT): Correlations Between Computed Tomography Findings and Cerebral Complications

Computed tomography (CT) is the modality of choice to characterize pulmonary arteriovenous malformations (PAVMs) in patients with hereditary haemorrhagic telangiectasia (HHT). The objective of this study was to determine if CT findings were associated with frequency of brain abscess and ischaemic stroke.

This retrospective study included patients with HHT-related PAVMs. CT results, PAVM presentation (unique, multiple, disseminated or diffuse), the number of PAVMs and the largest feeding artery size, were correlated to prevalence of ischaemic stroke and brain abscess.

Inclusion Criteria:

• Hereditary Haemorrhagic Telangiectasia (HHT) diagnosis
• Pulmonary Arteriovenous Malformations (PAVMs) related with HHT

Exclusion Criteria:

• Clinical follow-up not available in the database
