Interventional therapy for massive haemoptysis due to pulmonary sequestration / 介入放射学杂志

ABSTRACT

Objective To evaluate the clinical value and safety of angiography and embolization in the treatment of pulmonary sequestration causing massive haemoptysis. Methods Though digital subtraction angiography(DSA), abnormal arteries were demonstrated in 12 cases with massive haemoptysis. All the abnormal arteries were embolized by gelatin sponge plus silk thread sterilized with high temperature and pressure. Results Among 12 cases of the pulmonary sequestration, 26 abnormal arteries were discovered, originating from thoracic aorta and presenting enlargement, twisting and irregular diameter with strands of middle and distal arterial segments associated with abundant vasculature network. There were several arteries supplying the lesion in 11 cases, and massive haemoptysis were stopped after embolization. Follow up for 6 to 18 months, no recurrence and no complication occurred. Conclusion Arterial angiography and embolization with gelatin sponge plus silk thread for treating pulmonary sequestration with massive hemoptysis possesses high clinical efficiency and safety.
