Objective: To provide an overview of hereditary hemorrhagic telangiectasia (HHT), including its causes, symptoms, diagnosis, and management.
Approach: Key Findings: HHT is underrecognized and often diagnosed late. 90% of patients experience recurrent nosebleeds. AVMs can lead to serious complications, including stroke and heart failure. Interpretation: Early diagnosis and management of HHT are crucial to prevent severe complications associated with AVMs.
Limitations: HHT is frequently underdiagnosed due to lack of awareness. Symptoms may not appear until later in life, complicating early detection. Conclusion: Understanding HHT is vital for timely diagnosis and management to mitigate risks associated with the disorder.
