[Endovascular embolization for pulmonary artery pseudoaneurysms with massive hemoptysis]

Abstract

Objective: To investigate the efficacy and safety of transcatheter embolization for the treatment of pulmonary artery pseudoaneurysms (PAPs) with massive hemoptysis via both arterial and venous access. Methods: The clinical data of 15 patients of pulmonary tuberculosis presenting with massive hemoptysis, who were confirmed by CTA/DSA with PAPs at the Second Affiliated Hospital of Hainan Medical University from January 2016 to February 2018, were retrospectively analyzed. The imaging presentation, technical and clinical success of endovascular treatment, and recurrence of hemoptysis within 1 year was recorded. Results: A total of 15 PAPs were involved. Fourteen PAPs were confirmed by pulmonary CTA and one by angiography. Six PAPs were visualized during bronchial artery angiography, 4 PAPs during pulmonary artery angiography, and 4 PAPs both. One PAP was not shown during catheter-directed angiography. Except for one patient who died of asphyxia due to severe hemoptysis undergoing embolization, hemoptysis relapse was achieved in 14 patients after endovascular treatment. During 12 months follow-up, one patient underwent surgical resection because of recurrent hemoptysis 2 weeks after embolization, and another patient with recurrence hemoptysis 3 months after embolization received repeated intervention and hemoptysis relapsed. Conclusion: Transcatheter embolization via dual access is effective and feasible for the treatment of PAPs with massive hemoptysis in patients with pulmonary tuberculosis, but still some risks.
