Introduction: Pulmonary sequestration is a rare congenital malformation characterised by the presence of non-functional

and dysplastic pulmonary tissue that lacks communication with the tracheobronchial tree and has an aberrant non-pulmonary blood supply. Depending on its location, presence of the pleura covering, and venous drainage,

2 forms of pulmonary sequestration have been described: intra- and extralobar. Traditionally, surgical resection was performed; however, a growing number of cases have been treated with endovascular intervention.

Case report: A 38-year-old female patient was admitted to the hospital with severe haemoptysis for several hours. Examination at admission revealed tachycardia and tachypnoea. Computed tomography-examination disclosed the presence of an area of consolidation in the left lower lobe with a tortuous feeding artery arising from the descending aorta. Visible ground glass opacification indicated diffuse alveolar haemorrhage. Based on these findings, a diagnosis of intralobar sequestration of the left lung was made. The patient was consulted by a cardiothoracic surgeon and an interventional radiologist and qualified for endovascular treatment. In local anaesthesia femoral access was obtained and selective angiography of the common trunk of both bronchial arteries was performed. It depicted a dilated left bronchial artery supplying the sequestration and visible contrast extravasation. Embolisation of the vessel was performed with Glubran (n-butyl-cyanoacrylate). Control contrast injection showed complete elimination of the sequestration’s blood supply with no residual capillary blush. Clinical improvement was observed. No complications were encountered, and the patient was discharged 7 days after the procedure.

Conclusions: Arterial embolisation is a promising alternative to surgery in the treatment of symptomatic pulmonary sequestration.
