Arterioenteric or arteriotracheal fistula is a known complication of an aberrant right subclavian artery (ARSA) and is often associated with prolonged nasogastric or endotracheal intubation or oesophageal stenting. Fistula formation from the ARSA can present unexpectedly with rapid exsanguination with massive haemoptysis or haematemesis, and unless promptly recognised and treated is rapidly fatal. We present a novel endovascular method for treating a fistula between the oesophagus, trachea and an ARSA in an unstable patient following oesophageal stent removal, utilising a covered iliac limb stent, eliminating the need for an open surgical approach.
Pneumatosis coli (PC) is a rare radiological phenomenon of the presence of gas in the wall of the large intestine. It carries a large burden of morbidity and mortality. All patients should have their underlying cause of PC investigated and have targeted therapy. In this novel case, a 68-year-old man developed PC following an aorto-bilateral common iliac artery mycotic aneurysm excision. Fortunately, he was asymptomatic and underwent close surveillance of this condition until near resolution. This case highlights the need for correlation of the patient’s symptoms and clinical features with appropriate aetiology and pathogenesis mechanism of the disease to guide management and optimise health outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
