    Journal: Acta Radiol; 2008 Feb; 49(1):26-31. PubMed ID: 18210312.
    Abstract:
    BACKGROUND: Transcatheter arterial embolization (TAE) is a safe and well-established treatment option to control hemoptysis, but there are few studies focused on treating hemoptysis accompanying coal workers' pneumoconiosis (CWP). PURPOSE: To evaluate the immediate and long-term efficacy of TAE for control of massive hemoptysis in patients with CWP, and to clarify the factors which influence the frequency of rebleeding. MATERIAL AND METHODS: This study included 34 CWP patients with massive hemoptysis who were treated with 47 TAE sessions over the last 11 years. Immediate (within 1 month) and long-term outcomes (mean 37 months, range 1 month-11 years) were evaluated retrospectively. The relationships between the frequency of rebleeding and the type of CWP, angiographic findings, and presence of tuberculosis were evaluated. RESULTS: The immediate success rate was 91.2% (31/34). In 23 patients (68%), hemoptysis did not recur on long-term follow-up. In eight patients who received repeated procedures for recurrent hemoptysis, bleeding was discovered in the non-bronchial systemic artery (n = 13) or bronchial artery (n = 7). The frequency of recurrent hemoptysis was higher in cases with complicated pneumoconiosis (n = 7) than in cases of the simple type (n = 1; P = 0.029). There was no statistical difference between rebleeding and angiographic findings or the presence of tuberculosis. CONCLUSION: TAE is an effective treatment modality for controlling massive hemoptysis in patients with CWP. However, many non-bronchial systemic collaterals contribute to recurrent hemoptysis. Furthermore, there is a high probability of rebleeding in patients with the complicated type of CWP, and extra care must be taken in the embolization procedure.
