Summary:
Situation: Insertion of tubular stentgrafts in the management of acute type B dissection of the thoracic aorta has recently become
a popular alternative to open surgeries. The classical surgical procedure in complicated dissections is associated with mortality rates of
up to 50% and prolonged intensive care hospitalization. However, endovascular procedures have been associated with significantly lower
morbidity and mortality rates. There is insufficient experience with the stentgraft implantation outcome concerning both the septum dissection
and the lumini.
Case Review: A tubular stentgraft has been implanted to a forty-nine-year-old patient with acute, type B dissection. Immediate ischemic
and neurological complications, requiring reoperation and prolonged intensive care, were recorded postoperatively. The causes and
the management are discussed.
Conclusion: Endovascular management of the type B dissection is a popular, more patient-saving and healthcare professionals-saving
procedure, compared to classical open surgery. Pressure changes in the true and false aortic lumen may result in rapid reduction of the
organ and limb perfusion flow. These complications should be expected and must be managed urgently. Such surgeries should be performed
in clinical centres with appropriate facilities.
Key words:
