Large vessel rupture of aortic type III coarctation (DeBakey type III) is theoretically salvageable, but due to the critical condition after rupture, a slight delay can lead to hemorrhagic shock and death of the patient. Aortic type III entrapment is a condition in which the entrapment originates in the beginning of the descending aorta and extends downward into the thoracic descending aorta (DeBakey type IIIa) or even the abdominal aorta (DeBakey type IIIb). In a few cases, the entrapment may extend retrogradely into the aortic arch and ascending aorta, which is called a retrograde entrapment. A rupture may lead to severe chest pain, abdominal pain, and massive accumulation of blood in the thoracic and abdominal cavities, which may lead to ischemia of some organs, such as renal ischemia leading to acute renal failure, and, in severe cases, to hemorrhagic shock and death due to massive blood loss. Rupture should be repaired as soon as possible, if the treatment is timely, it may be salvageable; however, if the surgery is not timely, it can cause serious consequences. If you have an aortic coarctation, you should seek medical attention, control your blood pressure, and undergo endovascular repair within a limited period of time to prevent rupture of the coarctation.
