From the Guidelines
Aortic arch aneurysms can indeed result in neck changes on swallowing, particularly due to compression of the esophagus and surrounding structures. When an aortic arch aneurysm becomes large enough, it may compress the esophagus, leading to visible neck pulsations, asymmetric neck movements, or bulging in the neck area when swallowing 1. This compression can cause dysphagia (difficulty swallowing), voice changes, or a sensation of something stuck in the throat when eating. The aortic arch's close proximity to the esophagus means that an enlarged aneurysm can displace normal anatomical structures, leading to these symptoms. Some key points to consider include:
- The incidence of thoracic aortic aneurysms is estimated to be increasing, with around 10.4 cases per 100 000 person-years 1.
- Risk factors for development of thoracic aortic aneurysms include hypertension, smoking, and chronic obstructive pulmonary disease 1.
- Many patients with a thoracic aortic aneurysm are asymptomatic and diagnosed by chest x-ray or CT scan obtained for other reasons 1.
- Aortic arch aneurysms may cause compressive symptoms on adjacent structures, including hoarseness, stridor, dyspnea, dysphagia, and plethora and edema 1.
- Neck and jaw pain may occur with aortic arch aneurysms, whereas back, interscapular, and/or left shoulder pain may occur with descending thoracic aortic aneurysms 1. Given the potential risks associated with aortic arch aneurysms, including rupture and dissection, it is essential to promptly evaluate any symptoms or signs of aneurysm compression, such as neck changes during swallowing.
From the Research
Aortic Arch Aneurysms and Neck Changes on Swallowing
- There is no direct evidence in the provided studies to suggest that aortic arch aneurysms result in neck changes on swallowing 2, 3, 4, 5, 6.
- The studies primarily focus on the pathogenesis, therapeutic targets, and treatment options for aortic aneurysms, including the use of beta-blockers and the role of the renin-angiotensin system 2, 3, 4.
- One study discusses the effect of beta blockers on mortality after open repair of abdominal aortic aneurysm, but does not mention neck changes on swallowing 5.
- Another study compares the evaluation of abdominal aortic aneurysm using US, CT, MRI, and angiography, but does not address the specific question of neck changes on swallowing 6.
- Overall, there is a lack of research evidence to support a direct link between aortic arch aneurysms and neck changes on swallowing 2, 3, 4, 5, 6.
