    Abstract:
    OBJECTIVE: To identify the risk factors for early and late relapse of haemoptysis after bronchial artery embolisation (BAE). DESIGN: We performed a retrospective study of 255 patients with haemoptysis who underwent BAE from January 2009 to June 2016 at the First Affiliated Hospital of Nanjing Medical University, Nanjing, China. Using a Cox regression model, risk factors contributing to early (within the first month) and late (>1 month) recurrence were analysed. We censored recurrence-free patients at 1 month and patients without rebleeding after 1 month. RESULTS: The cumulative recurrence rate at 1, 6, 12, 24 and 48 months was respectively 14.9%, 16.9%, 20.6%, 31.0% and 39.9%, with a median follow-up of 574 days. Early relapse occurred in 38 of 255 patients, while late recurrence was found in 45 of the remaining 217 patients. The risk factors related to early recurrence were lung destruction on computed tomography of the chest and involvement of non-bronchial systemic arteries. The risk factors associated with late recurrence were tuberculosis sequelae, the presence of shunts and the use of gelfoam as an embolisation material. CONCLUSIONS: The variables related to incomplete embolisation were the risk factors for early rebleeding. The variables associated with same-vessel recanalisation and formation of a new collateral circulation influenced late recurrence.
