What causes Kommerell diverticulum?
Kommerell diverticulum, a remnant of the left dorsal arch, is located where the left aberrant subclavian artery originates, causing external posterior compression of the esophagus. Patients often become symptomatic in later decades as the arteries become tortuous and aneurismal.
Is Kommerell diverticulum an aneurysm?
Kommerell’s diverticulum refers to the aneurysmal dilatation of the descending aorta at the origin of an aberrant subclavian artery, which is seen in both right- and left-sided aortic arches.
What is an aberrant subclavian artery?
Aberrant right subclavian artery (ARSA) is a rare anomaly, in which the right subclavian artery arises directly from the aortic arch instead of originating from the brachiocephalic artery. This anomaly should be taken into consideration during surgical procedures around esophagus, such as esophagectomy.
What is bulbous configuration?
Conclusion The bulbous configuration of the basilar artery tip dubbed the ‘basilar shield’ is a benign, normal variant of the posterior intracranial arterial circulation. Further studies may be necessary to determine if there is any association with cerebral aneurysms, but the variant itself is innocuous.
How is esophageal diverticulum treated?
How is esophageal diverticulum treated? Cases of esophageal diverticulum that cause minor symptoms can be treated through lifestyle changes, such as eating a bland diet, chewing food thoroughly, and drinking plenty of water after meals.
Does diverticulitis cause a cough?
Symptomatic Kommerell’s diverticulum usually manifests with chest symptoms or dysphagia. In this particular case, the patient presented with an uncommon manifestation in the form of chronic cough.
What is aortic diverticulum?
The aortic diverticulum, a large bulge on the lesser curvature of the aortic isthums, is an occasional variation found during thoracic aortography in patients with a left aortic arch and normal origin of the brachiocephalic arteries.
What is left subclavian artery?
The left and right subclavian arteries are located in the thorax (chest) underneath the clavicles (commonly known as the collarbones). The left subclavian artery receives oxygenated blood from the aortic arch (the top portion of the largest artery in the body that carries blood away from the heart).
Is aberrant right subclavian artery life threatening?
Aberrant Right Subclavian Artery: A Life-threatening Anomaly that should be considered during Esophagectomy.
What is the treatment for aberrant right subclavian artery?
Aberrant right subclavian artery (RSA) is a rare congenital anomaly that usually does not produce symptoms. Symptomatic patients require surgical intervention.
What is the function of bulbous bow?
A bulbous bow is a protruding bulb at the bow (or front) of a ship just below the waterline. The bulb modifies the way the water flows around the hull, reducing drag and thus increasing speed, range, fuel efficiency, and stability.
How serious is right aortic arch?
Right aortic arch anomalies occur in approximately 0.01 to 0.1 percent of the general population. In general, these anomalies do not directly cause any cardiovascular problems.
What is the difference between an aneurysm and a diverticulum?
The term diverticulum may be more appropriately used when a vascular outpouching represents a persistent remnant of an embryological structure. The term aneurysm can be used to refer to an outpouching or dilatation which occurred due to vessel wall weakening.
What happens if the left subclavian artery is blocked?
Subclavian Steal Syndrome is a blockage of the subclavian artery which sits under the collarbone. It delivers blood to the arm and brain. The blockage causes the blood to flow in reverse. The arm “steals” blood flow from the blood which was intended for the posterior (back side) of the brain.
