Abstract
PURPOSE: Pulmonary artery pseudoaneurysms are a rare cause of massive hemoptysis and need to be considered as a differential with prompt recognition preventing mortality from life-threatening hemorrhage. We report the clinical details and imaging findings for a series of patients presenting with massive haemoptysis due to peripheral pulmonary artery pseudoaneurysm, managed by endovascular glue embolization. METHODS: Hospital based retrospective study wherein records and image database of patients presenting with massive hemoptysis between January 2014 and March 2016 were studied. The immediate technical success, reintervention rate, and recurrence of massive hemoptysis were recorded. RESULTS: Among patients with massive hemoptysis who underwent endovascular management in our department, seven patients fulfilled the inclusion criteria. The mean age was 54.3 years; mean lesion diameter was 10.8 mm (range 6-14 mm); underlying pathology being infective (tuberculosis) in all cases (n = 7). All lesions were treated with endovascular glue embolization. The technical success was 100%. Mean follow-up was 11.7 months. There was no case of recurrence of massive hemoptysis. There were no major complications with a single case of minor complication (in the form of chest pain and discomfort) which resolved with medical management. CONCLUSION: The endovascular approach using glue (N-butyl cyanoacrylate) is a minimally invasive and technically feasible, effective technique for emergent management of pulmonary artery pseudoaneurysms presenting as massive hemoptysis.
