Pancreatic arteriovenous malformations as a manifestation of hereditary haemorrhagic telangiectasia (Rendu-Osler-Weber disease): a systematic review - Report - MDSpire
Clinical Report: Pancreatic Arteriovenous Malformations in Hereditary Hemorrhagic Telangiectasia
Overview
This systematic review identifies 19 cases of pancreatic arteriovenous malformations (AVMs) in patients with hereditary hemorrhagic telangiectasia (HHT).
Background
Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant disorder characterized by vascular malformations, including arteriovenous malformations (AVMs). Pancreatic AVMs, while uncommon, can occur in HHT and may lead to significant complications. Understanding their characteristics and management is crucial for improving patient outcomes.

Mean AVM Size
7.1 mm
Percentage Asymptomatic

Conservative Management

CT as Diagnostic Modality
56%
Prognostic Information Unavailable
79%
Key Findings
19 patients with pancreatic AVMs in HHT were identified across 13 studies.
Females comprised 58% of the patient population, with a mean age of 52 years.
50% of patients were asymptomatic, and 73% had no laboratory abnormalities.
CT was the predominant diagnostic method, used in 56% of cases.
Conservative management was the approach for 69% of patients.
Serious complications occurred less frequently compared to general pancreatic AVMs.
Clinical Implications
The findings suggest that pancreatic AVMs in HHT may require less aggressive management, particularly in asymptomatic cases. Clinicians should consider conservative management and regular surveillance for these patients.
Conclusion
Pancreatic AVMs in individuals with HHT are typically smaller and more often asymptomatic than those in the general population.
