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 aortic Debranching?
Type I hybrid debranching: a dacron graft is directly sutured onto the ascending aorta using a partial clamping without the need for ECC, from which all the branches to SAT arise, with or without revascularization of the LSA.
What is a tevar procedure?
Thoracic endovascular aortic repair (TEVAR) is a procedure to treat an aneurysm in the upper part of your aorta. The aorta is your body’s largest artery. An aneurysm is a weak, bulging area in the aorta wall. If it bursts (ruptures), it can be deadly.
How is esophageal diverticulum treated?

What is a frozen elephant trunk procedure?
Abstract. The frozen elephant trunk (FET) procedure, or open stent grafting, is a tool for the combined open and endovascular treatment via a median sternotomy of extensive aortic disease involving both aortic arch and descending thoracic aorta.
Is TEVAR heart surgery?
An aneurysm is a weak, bulging area in the aorta wall. If it bursts (ruptures), it can be deadly. TEVAR is a minimally invasive surgery. That means it is done with a small cut (incision).
How long is TEVAR surgery?
Depending on the type of disease, the TEVAR procedure usually provides a cure. The procedure usually takes around two hours to complete.
Is esophageal diverticulum serious?
When symptoms of esophageal diverticula worsen, a person may be unable to swallow due to an obstruction near the diverticulum; rarely, the esophagus may rupture. An obstruction or rupture caused by an esophageal diverticulum is dangerous, and both complications require immediate attention.
Does diverticulitis cause chest pain?

Who invented Evar?
History. Dr. Juan C. Parodi introduced the minimally-invasive endovascular aneurysm repair (EVAR) to the world and performed the first successful endovascular repair of an abdominal aortic aneurysm on 7 September 1990 in Buenos Aires on a friend of Carlos Menem, the then President of Argentina.
