Development and validation of a novel nomogram for recurrent hemoptysis after bronchial artery embolization: a population-based cohort study.

ABSTRACT:

Background and objective

Recurrent hemoptysis after bronchial artery embolization (BAE) remains a significant clinical challenge. This study aims to develop and validate a predictive model to forecast hemoptysis recurrence post-BAE, enhancing clinical decision-making.

Methods

A retrospective analysis was conducted on 170 patients with hemoptysis from various causes who underwent their first BAE at three Chinese medical centers between January 2019 and December 2022. Data were split into training and validation groups (7:3 ratio). Independent predictors for recurrence were identified using the least absolute shrinkage and selection operator and multivariable logistic regression. Three models were developed: clinical (Model C), radiological (Model R), and combined (Model CR).
