Transcatheter closure of post-procedural right ventricular pseudoaneurysms in a neonate with pulmonary atresia

Post-procedural right ventricular pseudoaneurysm is a rare but life-threatening complication of interventional catheterisation. We describe a 3-day-old newborn who underwent transcatheter intervention for pulmonary atresia with a complication of right ventricular pseudoaneurysms, and transcatheter embolisation of the pseudoaneurysms was performed at 3-week-old. It is the first described case that receives transcatheter closure of right ventricular pseudoaneurysms in a newborn with a favourable outcome.

Pseudo to pseudo connection: pseudoaneurysm draining into the pseudocyst causing pseudohaemobillia

Haemosuccus pancreaticus (HP) is an exceedingly rare cause of lower gastrointestinal (GI) bleed where pseudoaneurysm of the peripancreatic vessels ruptures into a pancreatic pseudocyst and blood travel through the pancreatic duct, thereby, draining into GI tract via the ampulla of Vater. 1 We present a case of 65-year-old African-American woman with a history of alcohol abuse presented with melena for 1 day. The contrast-enhanced CT of abdomen/pelvis showed peripancreatic vascular pseudoaneurysm with active haemorrhage. Angiography confirmed the diagnosis of HP and successful transcatheter embolisation was performed.

Transcatheter correction of Scimitar syndrome: occlusion of abnormal pulmonary venous drainage and vascular supply in an infant

Treatment of Scimitar syndrome is usually surgical; however, if there is “dual drainage” – that is, one to the inferior caval vein and the other to the left atrium – it is possible to successfully treat this anomaly via a less-invasive transcatheter approach. We report a case of Scimitar syndrome in a 21-month-old, male infant successfully treated with transcatheter embolisation.

Use of Amplatzer Vascular Plugs for the treatment of combined extralobar and intralobar pulmonary sequestration in a 5-year-old child

Pulmonary sequestration is a rare congenital anomaly that can be asymptomatic or present with recurrent infections, respiratory symptoms, or rarely heart failure. Sequestration is classified as intralobar or extralobar on the basis of whether there is separation from normal lung tissue by its own visceral pleura. Classically, patients are treated with surgical resection. We present a case of multivessel, combined intralobar and extralobar pulmonary sequestration treated with transcatheter embolisation.
