Severe hemoptysis requiring bronchial artery embolization (BAE) shows seasonal patterns, with peaks in April and November. Understanding these temporal trends may aid in developing better preventive strategies for hemoptysis.
Area of Science:
- Pulmonology
- Interventional Radiology
Background:
- The seasonal periodicity of hemoptysis is not well-established.
- Temporal patterns of severe hemoptysis requiring intervention are poorly understood.
Purpose of the Study:
- To investigate the temporal patterns of severe hemoptysis.
- To analyze the timing of bronchial artery embolization (BAE) for hemoptysis over a 13-year period.
Main Methods:
- A 13-year retrospective analysis of consecutive patients undergoing BAE for hemoptysis.
- Statistical analysis, including linear regression, to identify temporal trends.
- Calculation of weekly and monthly seasonal indexes based on embolization events.
Main Results:
- Hemoptysis requiring BAE exhibited monthly variations.
- Two distinct monthly peaks in BAE procedures were observed: one in April and another in November.
Conclusions:
- Severe hemoptysis requiring BAE demonstrates a seasonal pattern with two annual peaks.
- Potential contributing factors include respiratory infections and weather variables.
- Identifying environmental triggers could enhance preventative measures for hemoptysis.
