Embolization of Pulmonary Pseudoaneurysms Secondary to Metastatic Synovial Sarcoma of the Right Atrium

Fever, haemoptysis and a mass in the heart

“…Pulmonary pseudoaneurysms have been reported before with sarcoma in the differential diagnosis. 2 A number of treatment options for pulmonary pseudoaneurysms have involved surgery, aneurysm embolization and immunosuppression. There have not been controlled therapeutic trials carried out and there is therefore debate concerning the best modality.…”

Coil Embolization of a Left Pulmonary Artery Pseudoaneurysm after Penetrating Injury

“…4 Complications include hemoptysis, thrombosis, infection, and distal embolization. 1,11,13 Several surgical techniques, such as lobectomy, pneumonectomy, hilar clamping with direct arterial repair, and ligation, have been used, 2 in addition to percutaneous catheter embolization, which carries a lower rate of morbidity and mortality than surgical resection. 4 Embolotherapy has become the treatment of choice for most Swan-Ganz catheter-induced PAPs.…”

“…4 Embolotherapy has become the treatment of choice for most Swan-Ganz catheter-induced PAPs. 14 Embolization, which is usually done in the arterial pedicle and sometimes the aneurysm sac, 4,13 can be accomplished with detachable silicone balloons, steel coils, gelfoam, polyvinyl alcohol particles, or n-butyl cyanoacrylate glue. 14 Complications are encountered rarely and consist of coil migration, misplaced coils, damage to the vessel wall, and delayed bacterial contamination of the thrombus and pulmonary artery.…”

“…14 Complications are encountered rarely and consist of coil migration, misplaced coils, damage to the vessel wall, and delayed bacterial contamination of the thrombus and pulmonary artery. 13 In our patient, we selected steel coils to embolize the feeding vessels, which proved efficacious and was less invasive than surgery.…”

Embolisation of large pulmonary artery pseudoaneurysm with conservative treatment of delayed coil extrusion

“…Embolisation-related complications in the context of pseudoaneurysms are infrequently encountered and mainly consist of coil migration, damage to the vessel wall and delayed bacterial contamination of the thrombus. (13) In the literature, there were only two reported cases of coil extrusion following embolisation procedures involving the pulmonary arteries, and both patients underwent a lobectomy. (14,15) Considering that a pseudoaneurysm does not possess a true intact wall, any interventional procedure for pseudoaneurysm repair is at risk of primary failure, especially if it involves coil deployment, which may easily penetrate the weak wall.…”
