Esophageal Necrosis After Endoprosthesis for Ruptured Thoracoabdominal Aneurysm Type I: Can Long-Segment Stent Grafting of the Thoracoabdominal Aorta Induce Transmural Necrosis?

Hybrid aortic arch repair for dissecting aneurysm

“…This complication is uncommon, with few cases reported in the literature. 18,19 The exact mechanism of secondary ischemic esophageal necrosis after TEVAR remains unknown; the hypotheses include pressure necrosis caused by the self-expanding endoprosthesis and ischemic esophageal necrosis due to disruption of the arteries that feed the esophagus. 18,19 In addition, the stroke and medullar complications rates were 6% and 3%, respectively, which is similar to the rate of stroke of 8.8% reported by B€ unger and colleagues.…”

Necrose esofágica aguda secundária a endoprótese: relato de caso de primeiro sobrevivente

“…A etiologia da necrose de esôfago é multifatorial. As principais etiologias consideradas como causas de necrose esofágica aguda são: refluxo ácido e hipoperfusão, obstrução (transitória ou completa) da saída do estômago e hipoperfusão por obstrução de fluxo arterial 1,26,32 . Em relação a esta última etiologia, três fatores podem estar envolvidos no processo de necrose esofágica: 1.…”

“…Apenas três casos foram descritos na literatura até a data deste estudo e em todos a complicação se mostrou fatal 1 . O presente trabalho descreve, até onde os autores conhecem, o primeiro caso de necrose esofágica aguda secundária a endoprótese de aorta, com sobrevivência do paciente.…”

Cardiovascular dysphagia — anatomical and clinical implications

“…With hyoid, larynx and pharynx affected most commonly, signs of incomplete tilting of the epiglottis, pharyngeal weakness and postdeglutitive aspiration can be found [79]. Postoperative dysphagia was reported following vascular ring division [9], type I thoracoabdominal aneurysm repair [33], arterial switch with the Lecompte maneuver [71], coil embolisation of an aortopulmonary collateral artery [8], and thoracic endovascular aortic repair [22]. Acute dysphagic syndrome after thoracic aorta endografting has been anecdotically reported, and its aetiology remains undefined [54].…”
