Summary
Aberrant right subclavian artery, a rare condition, can cause dysphagia lusoria. Awareness is key as it may be visible during endoscopy.
Area of Science:
- Vascular anatomy
- Gastroenterology
- Diagnostic imaging
Background:
- Aberrant right subclavian artery (ARSA) is a congenital anomaly affecting 0.4% of the population.
- Typically asymptomatic, ARSA can rarely lead to esophageal compression, termed dysphagia lusoria.
Observation:
- A case of dysphagia lusoria was diagnosed in 1 out of 920 patients undergoing diagnostic endoscopy.
- The diagnosis was confirmed using CT scan, highlighting the role of imaging in identifying this anomaly.
Findings:
- The study identified dysphagia lusoria in a patient presenting with swallowing difficulties.
- CT scan confirmed the aberrant right subclavian artery as the cause of esophageal compression.
Implications:
- Clinicians should consider ARSA in the differential diagnosis of dysphagia, especially when symptoms are unexplained.
- Endoscopic visualization may reveal the aberrant artery, aiding in diagnosis and management.

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:21Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
01:24Cardiac Catheterization III: Left Heart Catheterization
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
